Instagram (IG) is a mobile-first photo and video sharing platform offering two types of publishing formats, one is a post featuring an image or video with a description, the other is a story, featuring an ephemeral image or video with face-filters, stickers, polls and more all embedded in your story so there’s no further text attached it.
Since the launch of its Stories feature aimed at battling it out with Snapchat moments, Instagram seems to have unilaterally conquered the stories market, good move Zuckerberg 👏
Throughout 2017 Instagram has added an enormous amount of features aimed both at user engagement and business and advertisers. Features such as face-filters during live-stream and direct BigCommerce shopping integration, hmm.
Setting up your IG business account is pretty straightforward, as can be reviewed here and here. Make sure to fill in all your details (below) so leads can easily find and engage you.
* Profile picture - 110x110 px, circular
* Website (URL) - The URL can be changed throughout your account lifespan to feature specific campaigns and landing pages in place of your homepage.
* Bio (description) - you may use *#hashtags*
* Email
* Phone number
* Address
* Connected accounts - FB, twitter, etc.
* Start following - industry influencers correlating to your brand keywords.
A standard post contains either a picture or video attached to the description with text, #hashtags, @mentions and a geo-tag. IG allows you to run these posts through a color-filter giving images a distinct style. while private users tend to use these filters to give each image a unique style, successful brands use them to give their entire brand that same unique vibe by choosing a standard or custom filter and applying it consistently to each of their posts, allowing their content to be instantly recognizable, in time.
Posts may include up to 10 images and videos allowing for a broader story to be told through context.
Stories, which have a 24-hour life-span and are then deleted, feature face-filters, stickers, #hashtags, @mentiones, interactive polls, geolocations, text and a lot more all embedded in your picture/video making them standalone, with no description attached to them. Here’s a complete guide to this feature-filled medium.
While stories aren’t long lasting you can leverage popular stories you’ve posted via screenshots you’d then post back to IG or even use them as stickers in another story.
The live stream feature available via stories comes naked from all those amazing features we were getting used to from the regular stories. So it’s a plain live stream with the possibility to make it available for the next 24 hours. You can take screenshots of your story after the fact to post it back to IG or use’em as stickers in another one of your stories.
Since Instagram is such a limited platform in terms of functionality, marketers have to be exceptionally creative in order to create audience engagement with such limited resources.
Sprout article - There’s a lot to learn from the brands presented in this article, from multi-account segmentation to brand engagement. Do take time to look up the actual brands on IG and not just sift through the article.
Adobe - featuring artists using their products and hosting competitions such as #PeekAtProccess and #AdobeRemix, Adobe is hot with a capital H, do take some time to review their IG profiles.
TechCrunch article - since most of these are celeb brands which are not so akin to the brands you’ll be working on, please focus on storytelling techniques and branding user-generated content (UGC) which are a surefire way of engaging your target audience.
Community reach is extremely important in IG, as we mentioned you can @mention users in your post description as well on your stories. Also when commenting on user stories you can attach a photo of their story and use it as a sticker in yours, which is an amazing way to have a visual and engaging conversation with your audience.
Since you can’t attach URLs to your posts or stories, marketing efforts are practically non-existent on IG thus they are dependent results of your branding efforts and your profile set up i.e when you have engaging brand content on the IG platform and properly filled out your profile with a website URL, phone number etc. leads will come, unfortunately for us we can’t really force it as with other platforms where it’s possible to construct posts with calls-to-action (CTAs), links, etc
What you can do is change your website URL to a specific campaign or landing page at certain times when your branding efforts shift from your homepage message. You can always change it back to your homepage when these efforts come to an end.
One exception to this grim reality are IG Verified accounts who can attach URLs to their stories. The problem appears to be that there’s no genuine manner in which to request or attain an IG verified account, they’re just a Fugazi.
The second exception to this rule is instagram’s BigCommerce integration allowing you, as an e-commerce advertiser, to post your product catalog on Instagram where users can click and shop right from IG 🤑

While understanding our competitors is quite important, understanding our audience is valuable as well.
Instagram offers in-depth insights regarding the audience engaging with our brand. Starting from 100+ followers you’ll have the following information at your disposal:
Gender
Age group
Top Locations (cities) of your followers
Follower Hours - Hours of day your followers are engaged.
Follower Days- Days of week your followers are engaged.
Below are several suggested OKRs & KPIs aimed at measuring your continuous success on Instagram.
* Account Followers
* Post Impressions / Reach
* Profile Views
* Account Website URL Clicks
* Account Call Clicks
* Account Mail Clicks
* Account Mentions
* Branded #Hashtags in user posts
* Post Likes
* Post Comments
* Post Saves
* Video Post Views
* Story Impressions / Reach
* Story Exits
* Story Replies
* Measured on our own domain via GA, Mixpanel etc.
For suggested KPIs check SMM Fundamentals.
There are many different tactics available for you to try out and optimize in order to best reach and engage your audience. Below are several of those for your inspiration. I’d advise against counting on them alone but continuously research what sort of tactics have worked or might work well for your brand, industry and audience, and do not forget to measure the result of the tactics you engage against your original OKRs, in contrast to counting on any and all available metrics which might result in a focus on vanity metrics with no real impact on the business.
Unlike other platforms, IG is very visual, thus your polling story should be visually engaging as well. Opinion polls are available via IG Stories, allowing for two-predetermined-opinions, and viewing polling results per user. Though the story, as well as the poll results, disappear after a short 24 hours.
Once your polling is almost done, and before your story is deleted, make sure to take screenshots of the poll results along with your story to post back to IG once more, This should re-engage the same user base within the same context, it couldn’t get better than that.
Asking users for content such as images or #hashtagged stories could be an awesome, growth-driving endeavor if done with authenticity, and user-centric thinking. It could also easily backlash if done with a brand-centric perspective. Turns out users like feeling included but now feeling used, shocker.
This HubSpot article features several success stories for UGC generating campaigns on IG.
There could be no better way to engage your audience, generate hype, leads, subscriptions, conversions, and even UGC, like a prized contest. You may choose your winner in any number of ways, either editors-pick, most engagements collected, at random, or even give a prize to all participants as a promotion. Your prize must be something that users find valuable, but also something that’s connected to your brand. You can even give out coupons for your services at reduced prices.
Live streaming is a great way to engage your audience, offer live prizes and promotions, direct to your website URL or campaign landing page, and get more followers. Before streaming, make sure to publish posts and stories promoting the live stream at the time & date.
Social users love useful content, you could try uploading stories and or bulk-posts with multiple images to explain how to do something related to your brand.

Instagram is a very different platform from both FB and Twitter and is much closer to Snapchat than anything else. While converting users can be challenging, it can be done by having an i distinct brand image, engaging visual conversations and full-features posts telling a real story about your brand and it’s users.

Strictly's Kelvin Fletcher has viewers in tears telling romantic story about how he met his wife
The former Emmerdale star was in tears and so were viewers as he talked about Eliza
by Katie Fitzpatrick, Jasper KingStrictly Come Dancing fans were left in tears after Kelvin Fletcher told viewers the story about how he met his wife Eliza, reports the Manchester Evening News.

Kelvin played Andy Sudgen in Emmerdale and met Eliza at school and she was the first girl he ever kissed.
However, the pair lost contact when she went to university because Kelvin was working on Emmerdale. But their future together appears to have been mapped out.
The Oldham actor was in a bar in Manchester when by remarkable chance he found Eliza again.
"I'm in a random bar in Manchester and who of all people appears in the crowd dancing towards me?" he said.
Kelvin married Eliza in 2015, and they welcomed daughter Marnie in August 2016 and son Milo last December.
During the weekend's Strictly performance, he performed to their first dance song Do I Love You (Indeed I Do) by Frank Wilson with his dance partner Oti Mabuse.
"It will mean so much," he said ahead of their performance.
"When she walked down that aisle she took my breath away. Best moment of my life, it was just amazing," he said about their wedding day.
"I just want Liz to know how lucky I feel. Thank you for giving me two amazing incredible children."
And Eliza said about her husband: "He's everything, everything."
Viewers watching at home took to Twitter to say the introduction had melted their hearts.
"The way Kelvin speaks about his wife thoughhh..." said one.
"Kelvin's intro brought tears to my eyes. Could he be any more adorable? and his wife and children are beautiful," tweeted another.
"I’m in bits at how loved up Kelvin and his wife are and how perfect they are for each other," said another viewer.

Problem Solving and Javascript events and DOM Classes
Responding to user input and changing the web page
by: Peter Torr Smith
18th September, 2018
Tags/Categories
Tell your non-tech friend a story about a time you:
Got blocked on a simple problem
What was the problem?
Simple Javascript functions not being run when loading a test HTML page
What problem solving techniques did you use?
Debugging the Javascript as it ran (or didn't run) in the browser
Google searches for rules on the order of Javascript link tags.
How did you feel throughout the process?
Good, knowing there's a reason and that I'll find it if I just work the problem.
What did you learn?
For simple Javascript files that have some functions to run or call, the script tag to link in the .js file has to be after the html tag.
For more well structured .js files (libraries), these can go in the head tag as the .js files always wait for the document ready event before running the start() function to do things like add event listeners to the elements in the DOM.
Solved a problem in an elegant way
What was the problem?
The latest Dots Challenge I felt I solved in a relatively elegant way.
Instead of working through the sprint Javascript Dots Challenge instructions step by step, I first outlined the goals of the "game"
I then worked through the challenge on my own without looking at the hints in the instructions.
I came out with a working solution very similar to those outlined in the hints, so was proud of that
What problem solving techniques did you use?
Pseudocode in the form of // comments explaining what the goals and steps and mechanisms are
Debugging the Javascript as it ran in my browser.
How did you feel throughout the process?
Relaxed knowing that the problem was not that hard and that I'd learned all these techniques before in earlier exercises.
What did you learn?
that well worded pseudocode in comments is a fantastic way to keep the code honest.... that every function or line has a purpose, and to see ways to simplify or "refactor" the code to make it simpler, more re-useable, and easier to maintain.
Reflect on how confident you feel using the problem solving techniques and processes
They are
- Pseudocode
- Trying something
- Rubber ducky method
- Reading error messages
- Console.logging
- Debugging
- Googling
- Asking your peers for help
- Asking coaches for help
- Improving your process with reflection
I'm most comfortable with comment-style pseudocode, trying something, Reading error messages (often in the browser DevTools window), Searching online, and debugging.
I'm not using console.log too often anymore as the in-browser Javascript debugging is way easier and more powerful.
I've not had to use the Rubber Ducky method yet, but I do talk to myself ;-)
I've not felt I've needed too much to reach out to my peers or the coaches so far, but I expect that will be essential shortly as things get more complex.
I do think my process and proficiency are improving with reflection... both formal and informal.
- I have been capturing and posting about some experiences and learnings and research on good practice, so that has help reinforce my learnings into my practice.
- I have also been capturing random thoughts, learnings, questions, links, etc in some scrapbook / notebook files. They are not for presentation, but just to capture questions or learnings to let them ruminate or gestate as I work through the exercises, readings, examples and videos.


Airtel, RJio and 2 others bid for RCom assets
Creditors panel likely to meet on Friday
by Rajesh KurupBeleaguered telecom major Reliance Communications has received a total of 11 bids from four companies for assets housed under various subsidiaries, including that from India’s richest man Mukesh Ambani-controlled Reliance Jio Infocomm (RJio).
The others in the fray are Sunil Mittal-backed Bharti Airtel, PE firm Varde Partners and UV Asset Reconstruction Company (UVARCL), sources privy to the development told BusinessLine.

Bharti Airtel, which had earlier withdrawn its bid citing unfair treatment, has submitted a revised bid for RCom assets.
“The bidders have placed multiple bids for separate assets, and hence RCom has received a total of 11 bids from four companies. The Committee of Creditors (CoC) is slated to meet again on Friday to decide on the further course of action, including finalising a winner,” one of the sources said.
RCom’s assets include spectrum, tower, fibre, media convergence nodes and real estate, housed under three companies — RCom, Reliance Telecom and Reliance Infratel. The bids were invited separately for each firm.
₹33,000-crore debt
RCom, which is undergoing insolvency proceedings, has a total secured debt of about ₹33,000 crore. The Anil Ambani group company’s assets include spectrum, tower, fibre, media convergence nodes and real estate.
RJio placed its bid on Monday, while some of the bids, including that of Varde Partners, came in much earlier, sources added. Airtel also submitted its fresh bid on Monday. When contacted, RJio and Bharti Airtel spokesperson declined to comment, while Varde Partners and UVARCL could not be contacted.
On November 13, RCom had received bids from firms, including Sunil Mittal-controlled Bharti Airtel and Bharti Infratel and PE firm Varde Partners. However, RJio did not place its bid, but had sought a 10-day extension, which was granted by the CoC. Later, on November 17, Bharti Airtel withdrew its bid citing extension of deadline as unfair.
The extended deadline for the bids ended today.

By default, graphics go to the last graphics "device" you created and dev.off closes the last graphics device created. --- ## Vector versus Raster (pixel) graphics ```r pdf(file = "test.pdf", width=3, height=3) ggplot(cars, aes(x=speed)) + geom_density() dev.off() ``` ``` ## quartz_off_screen ## 2 ``` ```r png(filename = "test.png", width=3, height=3, units = "in",res = 100) ggplot(cars, aes(x=speed)) + geom_density() dev.off() ``` ``` ## quartz_off_screen ## 2 ``` --- ## File Size test.pdf: 9KB test.png: 16KB Raster graphics take more space but give worse results! In general, you will be better off using vector graphcics when makeing plots and graphs. --- ## Error Bars You create error bars in ggplot by adding an extra plot argument, geom_errorbar. You specify the top and bottom "y" position of the error bar, and optionally the width. You will have to calculate where the error bars should be and choose what they should represent (standard deviation, standard error, 95% confidence interval). --- ## Calculating Standard Error A standard method to achieve error bars would be to calculate standard error and store the value in a column. Be careful! There is a standard error function in R (stderr) that has nothing to do with standard errors! But you can define your on function to calculate it or use a package that supplies the standard error function. ```r sem <- function(x) sqrt(var(x, na.rm=T)/sum(!is.na(x))) cars %>% group_by(speed) %>% summarize(meanDist = mean(dist), semDist = sem(dist)) ``` ``` ## # A tibble: 19 x 3 ## speed meanDist semDist ## <dbl> <dbl> <dbl> ## 1 4 6 4 ## 2 7 13 9 ## 3 8 16 NA ## 4 9 10 NA ## 5 10 26 4.62 ## 6 11 22.5 5.5 ## 7 12 21.5 2.99 ## 8 13 35 4.12 ## 9 14 50.5 12.1 ## 10 15 33.3 10.5 ## 11 16 36 4 ## 12 17 40.7 5.21 ## 13 18 64.5 9.54 ## 14 19 50 9.45 ## 15 20 50.4 5.31 ## 16 22 66 NA ## 17 23 54 NA ## 18 24 93.8 10.2 ## 19 25 85 NA ``` --- ## Error Bar Example ```r sem <- function(x) sqrt(var(x, na.rm=T)/sum(!is.na(x))) cars %>% group_by(speed) %>% summarize(meanDist = mean(dist), semDist = sem(dist)) %>% ggplot(aes(x=speed, y=meanDist)) + geom_bar(stat="identity") + geom_errorbar(aes(ymin=meanDist - semDist, ymax= meanDist+semDist)) ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-5-1.png) --- ## Adjusting factor ordering If you are plotting a factor, you can determine the order that ggplot arranges things by changing the order of the factor ```r ggplot(chickwts, aes(x=feed, y=weight)) + geom_boxplot() ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-6-1.png) --- ## Changing the factor order ```r chickwts <- chickwts %>% mutate(feed = fct_reorder(feed, weight, mean)) ggplot(chickwts, aes(x=feed, y=weight)) + geom_boxplot() ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-7-1.png) --- ## Changing the axis title ```r ggplot(chickwts, aes(x=feed, y=weight)) + geom_boxplot() + labs(x = 'Feed Type', y = 'Chick Weight') ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-8-1.png) --- ## Changing the axis limits ```r ggplot(chickwts, aes(x=feed, y=weight)) + geom_boxplot() + scale_y_continuous("Chick Weight", limits=c(0,500)) + scale_x_discrete("Feed Type") ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-9-1.png) --- ## Log scale ```r ggplot(chickwts, aes(x=feed, y=weight)) + geom_boxplot() + scale_y_log10("Chick Weight", limits=c(10,500)) + scale_x_discrete("Feed Type") ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-10-1.png) --- ## Coloring of Factors ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500))+ labs(fill = 'Feed') ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-11-1.png) --- ## Manual Color Scale ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500)) + scale_fill_manual("Feed Type",values = c("red","orange","yellow","green","blue","violet")) ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-12-1.png) --- ## Fill Color Brewer ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500)) + scale_fill_brewer("Feed Type") ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-13-1.png) --- ## Fill Color Brewer ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500)) + scale_fill_grey("Feed Type") ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-14-1.png) --- ## Changing Plot "Theme" ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500)) + scale_fill_discrete("Feed Type") + theme_bw() ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-15-1.png) --- ## Minimal Theme ```r ggplot(chickwts, aes(x=weight, fill=feed)) + geom_density(alpha=0.5) + scale_x_continuous("Chick Weight", limits=c(0,500)) + scale_fill_discrete("Feed Type") + theme_minimal() ``` ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-16-1.png) --- ## Personal theme .pull-left[ ```r mytheme <- theme(axis.ticks = element_blank(), axis.text = element_text(color = 'blue', family='Times New Roman'), axis.title = element_text(color = 'red', family = 'Times New Roman', size = 20)) ggplot(chickwts, aes(x = weight, fill = feed))+geom_density(alpha = 0.5) + labs(x = 'Chick Weight', y = '', fill = 'Feed Type') + mytheme ``` ] .pull-right[ ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-18-1.png) ] --- ## Graph Refinement Chances are that you will continue to refine your graph during the manuscript process. Make the code for each graph a separate "R script", so that it is easy to: - Make changes - Regenerate the graph - See what data and commands were used to generate each graph - Cut and paste for similar work later --- ## Example Script  --- ## Multiple Graphs The packages `cowplot` and [`ggpubr`](https://rpkgs.datanovia.com/ggpubr/index.html) make putting different graphs on the same panel pretty straightforward. ```r # install.packages('cowplot') library(cowplot) p1 <- ggplot(iris, aes(Sepal.Length, Sepal.Width, color = Species)) + geom_point() + facet_grid(. ~ Species) + stat_smooth(method = "lm") + background_grid(major = 'y', minor = "none") + panel_border() + theme(legend.position = "none") # plot B p2 <- ggplot(iris, aes(Sepal.Length, fill = Species)) + geom_density(alpha = .7) + theme(legend.justification = "top") p2a <- p2 + theme(legend.position = "none") # plot C p3 <- ggplot(iris, aes(Sepal.Width, fill = Species)) + geom_density(alpha = .7) + theme(legend.position = "none") # legend legend <- get_legend(p2) # align all plots vertically plots <- align_plots(p1, p2a, p3, align = 'v', axis = 'l') # put together bottom row and then everything bottom_row <- plot_grid(plots[[2]], plots[[3]], legend, labels = c("B", "C"), rel_widths = c(1, 1, .3), nrow = 1) plot_grid(plots[[1]], bottom_row, labels = c("A"), ncol = 1) ``` --- ## Multiple Graphs  --- ## Multiple plots .pull-left[ ```r library(ggpubr) data("ToothGrowth") df <- ToothGrowth df$dose <- as.factor(df$dose) # Create some plots # :::::::::::::::::::::::::::::::::::::::::::::::::: # Box plot bxp <- ggboxplot(df, x = "dose", y = "len", color = "dose", palette = "jco") # Dot plot dp <- ggdotplot(df, x = "dose", y = "len", color = "dose", palette = "jco") ggarrange(bxp, dp, common.legend = TRUE) ``` ] .pull-right[ ![](lecture_pubgraphics_files/figure-html/unnamed-chunk-23-1.png) ] --- ## Fine-tuning the theme ```r plt <- ggplot(bl, aes(x = estimate)) + geom_histogram(bins = 50)+#geom_density() + facet_grid(Event ~ Race, scales = 'free', switch = 'y', space = 'free_x') + geom_vline(xintercept = 1, linetype = 2) + geom_segment(data = bl2, aes(x = estimate, xend=estimate, yend = 5, y = hts), color='red', size = 1.5, arrow = arrow(length = unit(.2, 'cm')))+ scale_x_continuous(breaks = c(1, seq(0.7, 1.8, by = 0.2)))+ # Unified the x-axis ticks labs(x = 'Adjusted HR, compared to Whites', y = '') + * theme(strip.text = element_text(size = 14, face = 'bold'), * strip.text.y = element_text(angle = 180), # Rotate the y-axis labels * strip.background.x = element_rect(fill = 'white'), * strip.placement = 'outside', # Move labels outside the borders * axis.text.y = element_blank(), * axis.ticks.y = element_blank(), * axis.text.x = element_text(size = 8), * panel.spacing.x = unit(2, 'lines')) ``` --- ![](lecture_pubgraphics_data/Figure2a.png) --- ## Directly creating PowerPoints You can now use RMarkdown to create PowerPoint presentations [reference](https://bookdown.org/yihui/rmarkdown/powerpoint-presentation.html){target="_blank"} ``` --- title: "Your Presentation" author" "James T. Kirk" output: powerpoint_presentation --- ``` This might be useful if you want to copy slides into different presentations directly. --- class: inverse, center, middle ## Final Presentations --- ## Final Presentations I would like to suggest that everyone send their final presentation to me as a "pdf" file, with the file name being "LastFirst.pdf" (for example "BuehlerEugen.pdf"). This will make it easy to order the files into a single presentation. Two hours is not a lot of time for so many people to present, so there may be only ~10 minutes per person for presentations. It is OK to add slides that you want us to see but that you have to skip over for time. --- ## Final Presentation Contents Should include the following five elements, demonstrating the code and the results of the code to

Use a package not loaded by default in the base distribution
Read in a data set from a file
Manipulate the data in some way
Do a statistical test of the data
Make a graph from the data
 The material doesn't have to be presented in that order, and could include more (data background, more than one graph or statistical test, etc). Your grade will be determined based on how many of the five requirements your demonstrate (in your slides). --- ## Grading Scheme

A = All five elements demonstrated
B = Four elements demonstrated
C = Three elements demonstrated
D = Two elements demonstrated
F = One or zero elements demonstrated

SIMPLIFYING CONCEPTS
The Internet is a structure made up of millios of computers whose users can communicate with each other and share information.
The World Wide Web (WWW) gives Internet users easy access to information on the Internet.
HTML is Hypertext Markup Language and it is the main, or most common, type of document on the web. There are other types such as text, images, videos, and music. HTML was designed to describe the contents of a web page in a very general way.
HTTP is Hypertext Transfer Protocol that sends requests to a srver.
 The programmers have to write in a language that the computer can read. This is referred to as CODING.
Let's take a look at some of the basic HTML vocabulary.
ELEMENT: Everything within a set of opening and closing tags.
TAG: Turns on a feature which is indicated by an opening tag, and turns off a feature indicated by a closing tag.
INLINE ELEMENTS: Tags that do not require a closing tag.
BLOCK ELEMENTS: Tags that require a closing tag. Block Elements are similar to an invisible box being placed around the text.
ATTRIBUTE: A property of an HTML element.
There is a tag to do BOLD text.
There is a tag to do emphasis such as italics.
There are also tags to do line breaks and paragraphs.
There are many others. There are tags to do almost everything.


Intel Turns to Foundries to Fix CPU Shipment Delays, as OEMs Fume
“We have not yet resolved this issue”
Intel has apologised to customers for ongoing CPU shipment delays, telling partners “we appreciate [this] is creating significant challenges for your business” and admitting that supply-demand balance “remains a challenge”.
“Despite our best efforts, we have not yet resolved this challenge” (recent PC CPU shipment delays), Intel GM Michelle Johnston Holthaus said, in a letter that suggests it is giving customers revised shipment schedules for PC CPUs.
The letter of apology is just the latest in a drumbeat of regular apologies from Intel: “We’re letting our customers down” CEO Bob Swan said bluntly on an October earnings call of the issue, which first hit headlines in 2018.
Holthaus said Intel is doing all it can to ramp up production of its 14nm PC CPUs, amid growing OEM frustration, including “increasing our use of foundries” (something the company declined to specifically commit to in response to questions from analysts in a Q3 earnings call).
“In response to continued strong demand, we have invested record levels of Capex increasing our 14nm wafer capacity this year while also ramping 10nm production,” she said, adding that “in addition to expanding Intel’s own manufacturing capability, we are increasing our use of foundries to enable Intel’s differentiated manufacturing to produce more Intel CPU products.”
The capacity boost will let Intel increase its second-half PC CPU supply by double digits compared with the first half of this year, she said.
“[But] supply remains extremely tight in our PC business where we are operating with limited inventory buffers. This makes us less able to absorb the impact of any production variability, which we have experienced in the quarter. This has resulted in the shipment delays you are experiencing, which we appreciate is creating significant challenges for your business.”
Intel is speaking to customers directly amid freshly revised shipment schedules, the company admitted. Whether rivals like AMD can ramp up enough production to steal some of that frustrated demand, and OEM’s have enough contractual flexibility to do so should they wish is something of an open question: OEMs are no doubt thinking hard about diversifying more.

In this tutorial we will show the application of the forward-backward dynamic mode decomposition (see Dawson et al.) applied to the numerical solutions of a fluid dynamics problem. We run a simple simulation with the software OpenFOAM, taking one of the several tutorials provided: in this case, we simulate the flow of an incompressible turbulent fluid around some buildings by solving the Reynolds-averaged Navier Stokes equations using the k-$\epsilon$ model. We will not discuss the simulation details, since the main purpose of this tutorial is to show a PyDMD usecase with numerical data, you can find all the information at this link.
First of all we import the FbDMD and the DMD classes from the pydmd package, we set matplotlib for the notebook, we import numpy and we import Ipython widgets (for some magic trick).
%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
import time
from pydmd import FbDMD
from pydmd import DMD
from ipywidgets import interact_manual, interact, interactive, FloatSlider
Now, we import the $x$ component of the flow velocity at the ground. In order to visualize the dataset, we load also the points coordinates.
snapshots = [
np.genfromtxt('data/velocity0.{}.csv'.format(i), delimiter=',', skip_header=1)[:, 0]
for i in range(20, 40)
]
pts = np.genfromtxt('data/velocity0.20.csv', delimiter=',', skip_header=1)[:, -3:-1]
We show some snapshots: since the original system was discretized using an unstructured grid, the visualization is not easy. We use a simple scatter plot in order to have an idea of what we are trying to analyze.
plt.figure(figsize=(16, 16))
for i, snapshot in enumerate(snapshots[::5], start=1):
plt.subplot(2, 2, i)
plt.scatter(pts[:, 0], pts[:, 1], c=snapshot, marker='.')
plt.show()
Alright, now we can decompose the snapshots matrix: we instantiate the new object then fit the snapshots. We remind that the argument of the fit
method can be a 2D numpy.ndarray or a simple iterable object, like a list or a tuple.
fbdmd = FbDMD(exact=True)
fbdmd.fit(snapshots)
fbdmd.reconstructed_data.shape
The forward-backward version reduces the error by computing the low-rank linear operator as the square root of the product between the operator for the forward evolution and the operator for the backward evolution. The FbDMD
class has the same attributes and methods of the DMD
class. Try to compare this version with the original one, by checking the stability of the dynamics.
dmd = DMD(exact=True)
dmd.fit(snapshots)
print('[DMD ] Total distance between eigenvalues and unit circle: {}'.format(
np.sum(np.abs(dmd.eigs.real**2 + dmd.eigs.imag**2 - 1))
))
print('[FbDMD] Total distance between eigenvalues and unit circle: {}'.format(
np.sum(np.abs(fbdmd.eigs.real**2 + fbdmd.eigs.imag**2 - 1))
))
dmd.plot_eigs()
fbdmd.plot_eigs()
The eigenvalues from the forward-backward dynamic mode decomposition are closer to unit circle, compared to the ones from the standard DMD! Dealing with numerical solutions, where a small noise is often present, this algorithm can be the right way.
Now let's manipulate the temporal window in order to have a small future prediction of the system. Moreover, we halve the delta-time in order to have more reconstructed snapshots.
fbdmd.dmd_time['dt'] *= .5
fbdmd.dmd_time['tend'] += 10
plt.plot(fbdmd.dmd_timesteps, fbdmd.dynamics.T.real)
plt.show()
To conclude the tutorial, the coolest part! We create a simple function that plots the proper reconstructed snapshot given the right time. Then we use the Ipython widgets to interactively show the states of the system, allowing the user to understand the evolution just touching a slider. If you have an old version of the ipython widgets it is possible that this line: output.layout.height = '500px', produces some trouble. Just comment it in that case.
def plot_state(time):
i = int((time - fbdmd.dmd_time['t0']) / fbdmd.dmd_time['dt'])
plt.figure(figsize=(8,8))
plt.scatter(pts[:, 0], pts[:, 1], c=fbdmd.reconstructed_data[:, i].real, marker='.')
plt.show()
interactive_plot = interactive(
plot_state,
time=FloatSlider(
min=fbdmd.dmd_time['t0'],
max=fbdmd.dmd_time['tend'],
step=fbdmd.dmd_time['dt'],
value=0,
continuous_update=False
)
)
output = interactive_plot.children[-1]
output.layout.height = '500px'
interactive_plot
We successfully use the PyDMD package to data that comes from a real application, using the forward-backward algorithm in order to delete the numerical noise.

Ombudsman Exposition - Kevin Rattai
Ombudsman Candidates
As we approach the velection of the vOmbudsman, I offer myself to the voting
populace:
I am Kevin Rattai from Beausejour, MB, CA. I am an independant computer
analyst/programmer by training, I am a VR enthusiast by design.
My roots in the VR community are deep. I became a proponent and student of
Human/Computer Interaction and Useability in 1979 with a letter to
Intellivision (one of the first North American CGA home entertainment
makers, aside from Atari) stating that they might have something that would
really make people notice them if they were to give the player a 'first
person' viewpoint. (btw, they wrote back saying, "thanks, we have people
doing that type of research"). The rest is history. I started writing ray
tracers, CAD/3D modelling, simulation, and user interface software in 1989
because I couldn't find anything that _really_ fit my needs. In 1992 I
heard about VR while at a User Interface Stratagies Seminar, read about it
in a book by Howard Rheingold "Virtual Reality", and haven't slept since.
I've maintained close relationships with Tony Havelka of Liquid Image
(they're local) and Karen August of VRASP since the beginning of 1993. I
became involved in VRML after doing a search of VR on some webcrawlers back
in October of 1995.
I am interested in being on the committee because I believe the technology
is more than ready to be placed into the publics hands. As this community
grows, there will be issues that may not be able to be resolved. At that
time, those of the committee need to take a holistic view of the issue and
consider the implications for now and into the future. I believe that I am
quite capable to perform those duties. I do not believe that the committee
should be a governing body. It should be an Ombudsman, to resolve
conflicts. As well, it should be a guiding light as to where this project
may lead to in 6 months, 1 year, and 5 years.
Thank you for listening,
Kevin

---
The goal of this game is to choose your own adventure, and learn how to navigate the internet, also known as the Web!
- Learning Goal: Learning how to navigate the web!
- Setting: Both a web, and the internet. It's playing upon both meanings of web!
- Things to Collect: Flies, before they are eaten by spiders
- How to Win: Collect ALL of the flies
- How to lose: Miss a fly and it gets eaten in the web


THE RAGE: CARRIE 2 (M). (MGM/UA/UIP) Director: Katt Shea Stars: Emily Bergl, Jason London, Dylan Bruno, Amy Irving, Zachery Ty Bryan, J Smith-Cameron, John Doe, Gordon Clapp, Rachel Blanchard, Charlotte Ayanna, Justin Urich, Mena Suvari, Elijah Craig, Eddie Kaye Thomas, Clint Jordan, Steven Ford, Kate Skinner, Katt Shea Running time: 104 minutes.
The scene: the offices of MGM/UA studios in Hollywood, sometime last year. We are privy to a rare conversation between two production executives.
"We've got a pretty thin slate this year until the next Bond film comes out. What can we do to beef it up a little?"
"Sequels and remakes always do reasonable business."
"Yes, but we've already done The Mod Squad, and we've still got the remake of The Thomas Crown Affair on the way."

"I know the perfect film, too! Remember that fantastic horror film from 1976. That one about the tormented adolescent with telekinetic powers who destroyed her school on prom night. That one that made the reputations of both Brian De Palma and Stephen King? What was it called... Carrie? It's old enough now that most of today's audiences probably won't have seen it, or won't remember it."
"So, what's the hook?"
"We set it 20 years later, and we bring back Amy Irving's character. She was the only one to survive that spectacular conflagration. We make her a guidance counsellor at her old high school. She can recognise the telekinetic powers in another outcast, and try and prevent another disaster."
"And, as an added twist, we'll make the new kid the illegitimate daughter of Carrie's father, a sort of half- sister. Things will escalate until she erupts and unleashes her full fury."
"We'll get some unknown actress to play our heroine."
"This will be her big break, just like the original was for Sissy Spacek!"
"And let's have the football jocks be her tormentors. They're playing a kinky and cruel game whereby they score points for seducing various girls at school."
"And we'll have our spunky male hero also an innocent victim of a prank organised by a vindictive student."
"Yeah! Our film will really explore the bitchy politics, the cliques and social undercurrents that are an integral part of contemporary high school life."
"But, hasn't that angle already been explored ad nauseam already this year?
"Yeah, but they were all comedies. This will be a horror story for adolescents."
"You mean like Scream and I Know What You Did Last Summer and that ilk?"
"Yes, but without the scary bits."
"And we've got to have a scary coda. Like that final scene in Carrie when the bloodied hand reaches out of the grave and grabs Amy Irving's arm, and it turns out to be a dream. I really jumped at that bit."
"Even if that sort of thing has now become a cliché and not terribly scary?"
"Yes, we've got to have that. Audiences expect that sort of thing nowadays."
"Will we have some big names in the cast? I mean the original had people like Sissy Spacek, John Travolta and William Katt before they really became famous."
"Well, we could have a tv star in it. What about that kid from Home Improvement?"
"You mean Jonathan Taylor Thomas? He'd be a big name and would draw in the female demographic."
"No, I was thinking of that other one, the guy who plays Brad. Zachery Ty Bryan."
"He'll be great, especially when cast against type as a villainous sort. And we'll have lots of fresh young faces play the rest of the students."
"Will we show the script to Stephen King first for approval?"
"No, he'd just hate it and what we've done to his story. And he'd probably want to direct. We all know what happened with Maximum Overdrive!"
"So who will we get to direct?"
"Probably a woman, who will bring an added dimension to the horror genre. Someone who has made a few teen flicks and has indy credibility. And most importantly, someone with a unique visual style - lots of moving cameras, flashy and atmospheric switches between colour and black and white. Someone whose pretentious style will distract from the lack of originality and credibility and the ham fisted performances of the cast."
"I think we have a real winner here!"
Cut to the present day. Distressed film reviewer wakes up in a darkened cinema with the credits rolling across the screen, hoping that it was all just a bad dream. No! Unfortunately, it was a very bad film!

Today I ate a big salad with tuna, split the salad in two, ate two apples, each with a whole meal, and one yogurt. In general, she was thoughtful of satiety, I felt good and drank lots of tea.
In the evening I did a workout for the lower body, for the core that is ABS and shoulders, I started with cardio to do body warming and I did well in all the other exercises I did, hoping to see very positive results over the weekend.
wish me luck.
Good night.

When is it more effective to call/email/mail and why?
We recommend that you show up to town halls or call if the matter in hand is urgent or if your message is short. For a more detailed message, we recommend sending emails or mails. While the Congress staffers may send you generic letters in response to your email or mail, they have to interact with you directly if you call or show up at a town hall. Thus to spur a more rapid change, phone call or town hall attendance are helpful.
Why do we insist on personalized letter?
Generic letters tend to generate generic responses. If you take your time to produce a personalized letter with facts and figures, Congress staffers are more likely to consider your letter seriously and send you a personalized response.
How does the language generation work?
Answer
Why is it more effective to send an email from the representative’s site, rather than from an aggregator or an organization?
Answer
Why is it important to ask for a specific response from your representative?
If you do not ask for specific responses, the office of the representative may send you a generic response. When you ask for specific responses, the office will have to send you a personalized response and you will know more about whether your representative supports your cause or is against it.
Which members of Congress should you contact for which issues and why?
Answer
Why should you focus on contacting your own representatives?
Because your vote directly influences the status of your representative, it is more likely that your congressional representative will take your letter more seriously than a letter from someone whom he or she does not represent. Thus we strongly recommend that you include your address or use a phone number with your home address area code to have more impact.
When is it effective to contact members of specific committees?
It is best to contact members when laws are being drafted or are being debated in the Congress.

Version: 1.2.0
Authors: John Krukoff (github@cultist.org).
An Erlang/OTP library for working with iterators; an opaque type that is evaluated as a lazily evaluated list of elements. This allows for memory efficient processing of sequential data and easy composition of processing on such lazy lists.
An interface identical to the stdlib lists
module is implemented, allowing
for easy conversion between list processing code and lazy list processing
code.
This library is published to hex.pm as llists. If you're using rebar3 as your build tool, it can be added as a dependency to your rebar.config as follows:
{deps, [{llists}]}.
To use this library, it is first necessary to create an iterator. This can
either be done from an existing data structure using functions like
llists:from_list/1
or by expressing the continuation programmatically using
functions like llists:unfold/2
.
Once an iterator is constructed, it can then be evaluated an element at a time
using llists:next/1
or by using one of the many utility and evaluation
functions in llists
or llists_utils
.
llists
contains an iterator aware version of every function in the stdlib
lists
module, with guaranteed identical behaviour for side effect free and
finite iterators.
lfiles
contains file utility functions replicating functionality from the
file
and io
modules. Read functions create impure iterators that should
only be evaluated once. Write functions consume iterators and write the
produced data to a file.
An iterator is an opaque record created by the llists
module to represent a
continuation. When evaluated by llists:next/1
an iterator returns a lazy
list, represented by one of two options:
[]
: An empty list, signaling that no more elements are available.[Elem | Iterator]
: An improper list consisting of an element and an
iterator to continue evaluation.As an example task, let us calculate the mean difference between a list of
integer pairs. These pairs are stored in a file as
comma separated values, one per line. We can use the llists
module to both
read lines from the file and calculate the average lazily, thus avoiding
loading the entire file into memory during computation.
First, we need to construct the iterator:
> {ok, File} = file:open("doc/example.txt", [read]). {ok,<0.227.0>} > I = llists:unfold(fun(File) -> case file:read_line(File) of {ok, Data} -> {Data, File}; eof -> file:close(File), none end end, File). {iterator,#Fun<llists.2.38967554>}
Next, a loop to parse the strings and calculate the mean difference:
> F = fun Calculate(I, Sum, Count) -> case llists:next(I) of [] -> Sum / Count; [Elem | Next] -> [A, B] = [list_to_integer(string:trim(Part)) || Part <- string:split(Elem, ",")], Calculate(Next, Sum + (A - B), Count + 1) end end. #Fun<erl_eval.17.3316493> > F(I, 0, 0). -0.42
We could also make use of the utility functions in llists
and lfiles
and
compose the same result as follows:
> {ok, File} = file:open("doc/example.txt", [read]). {ok,<0.227.0>} > I = lfiles:read_line(File). {iterator,#Fun<llists.2.38967554>} > Split = llists:map(fun (Elem) -> string:split(Elem, ",") end, I). {iterator,#Fun<llists.23.38967554>} > Integers = llists:map(fun (Parts) -> [list_to_integer(string:trim(Part)) || Part <- Parts] end, Split). {iterator,#Fun<llists.23.38967554>} > {Sum, Count} = llists:foldl(fun ([A, B], {Sum, Count}) -> {Sum + (A - B), Count + 1} end, {0, 0}, Integers). {-42,100} > file:close(File). ok > Sum / Count. -0.42
In both examples, we read only a single line of the file into memory at a time.
Notice that we couldn't use llists:sum/1
and llists:length/1
here instead
of llists:foldl/3
, since our input iterator has side effects and can only be
evaluated once.
Please fork the repo and submit a PR. Tests are run automatically on the master branch by GitHub actions or can be run locally via:
make deps make check
If a Unix environment is not available, tests can be run inside a docker container via:
docker-compose build docker-compose run check
Documentation is autogenerated using edown and edoc via:
make doc
Development of the library should be done with an Erlang/OTP version of 25 or greater.
The library requires an Erlang/OTP version of 21 or greater to function. Earlier versions may work if functions involving maps are avoided.
Streams and lazily evaluated lists are common language constructs and much prior art exists. Scheme's SRFI-41 served as a useful design document to base this work on.

Sticky toffee pudding made easy - no steaming, no caramel to make, just tasty springy sponge and a treacle toffee sauce.
Preheat the oven to 190C/375F/Gas 5.
Butter eight small pudding basins (dariole moulds) and sprinkle demerara sugar inside, coating evenly. Shake any excess sugar out of the moulds, and place them on a baking tray.
Place the dates with 250ml/9fl oz water into a saucepan and bring up to the boil. Reduce the heat and simmer for 2-3 minutes. Remove the pan from the heat.
Stir the vanilla extract into the date mixture.
Blend with a stick blender until the date mixture is thick and soupy.
In a large bowl, beat the butter and muscovado sugar together until smooth.
Stir in the syrup and treacle, then the flour, mixing well.
Break the eggs one at a time into the bowl, stirring well after each one.
Add the bicarbonate of soda to the date mixture, then pour into the flour mixture and beat well to blend.
Pour the mixture into the prepared pudding basins, filling them two-thirds full.
Put the puddings into the oven immediately, and bake for 20 minutes until well-risen and springy to the touch.
For the sauce, gently heat the cream in a saucepan. Add the sugar and butter and whisk until melted. Whisk in the syrup and treacle.
To serve, turn the pudding out onto a plate, spoon the sauce over the top and around, then finish with a dollop of ice cream.


Once I made my portfolio, GitHub, and first project, it was time to to take the next step. Front end development is by no means easy, but it is quicker to pick up and far more rewarding for beginners than back end because you can see the changes you are making in real time.
Modern front ends are built with “single page applications.” To summarize SPAs in one sentence; instead of having many HTML pages they only have one. The server sends sends the appropriate data to display on that page. This has all kinds of benefits, one of which is component-based development. When an SPA is interacted with, the entire page does not need to reload; only the parts, or components, that have changed need to reload. This creates opportunity for lightening-fast loading and more enjoyable user experiences.
I could write an entire page about SPAs, but that is not what this article is about. As I said before, modern websites are built using these frameworks so it is a good idea to learn one. The big three right now are React, Angular, and Vue. React was made by Facebook and the other two by Google. As a beginner I highly suggest picking either React or Vue because Angular is harder to jump into without a ton of preparation. If you are really stuck on which to choose, try looking at your area's job market. Go on Indeed and see which of the three is most in-demand.
Picking a project for your application can be tough because it should be complex enough to warrant using a framework. Basically, your website needs to be highly interactive before using a framework is necessary. I'm into fitness so I decided to make an application where you could make exercises and track them. Yes, this was basically a glorified shopping list, but that's alright. I was learning while being mildly creative which is all that really matters.
I will provide links to things I think helped me learn about front end web frameworks. I highly suggest picking a framework, making a simple interactive project, and adding features until you feel like you understand the technology. In my next post I hope to begin diving into coding concepts instead of another “how to get started.” Stay tuned, thanks for reading.

I think it's about time I started to blog more again. This site has been woefully neglected over the last year or so so I'm going to commit to writing more of my thoughts down on here. Previously, this blog was called STEP (Society, Technology, Education and Politics). At the time, I was working in the education sector but now I'm in housing so I've got to come up with some sort of name change I guess. Not quite sure STHP works so well. Answers on a postcard (comments feed!) for a new name for the blog.

(Sample Data taken from wikipedia on jQuery article)
jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML. jQuery is the most popular JavaScript library in use today, with installation on 65% of the top 10 million highest-trafficked sites on the Web. jQuery is free, open-source software licensed under the MIT License.
jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications.
The set of jQuery core features—DOM element selections, traversal and manipulation—enabled by its selector engine (named "Sizzle" from v1.3), created a new "programming style", fusing algorithms and DOM data structures. This style influenced the architecture of other JavaScript frameworks like YUI v3 and Dojo, later stimulating the creation of the standard Selectors API.
Microsoft and Nokia bundle jQuery on their platforms. Microsoft includes it with Visual Studio for use within Microsoft's ASP.NET AJAX and ASP.NET MVC frameworks while Nokia has integrated it into the Web Run-Time widget development platform. jQuery has also been used in MediaWiki since version 1.16.
jQuery, at its core, is a DOM (Document Object Model) manipulation library. The DOM is a tree-structure representation of all the elements of a Web page and jQuery simplifies the syntax for finding, selecting, and manipulating these DOM elements. For example, jQuery can be used for finding an element in the document with a certain property (e.g. all elements with an h1 tag), changing one or more of its attributes (e.g. color, visibility), or making it respond to an event (e.g. a mouse click).
jQuery also provides a paradigm for event handling that goes beyond basic DOM element selection and manipulation. The event assignment and the event callback function definition are done in a single step in a single location in the code. jQuery also aims to incorporate other highly used JavaScript functionality (e.g. fade ins and fade outs when hiding elements, animations by manipulating CSS properties)
jQuery's architecture allows developers to create plug-in code to extend its function. There are thousands of jQuery plug-ins available on the Web that cover a range of functions, such as Ajax helpers, Web services, datagrids, dynamic lists, XML and XSLT tools, drag and drop, events, cookie handling, and modal windows.
An important source of jQuery plug-ins is the plugins subdomain of the jQuery Project website. The plugins in this subdomain, however, were accidentally deleted in December 2011 in an attempt to rid the site of spam. The new site will include a GitHub-hosted repository, which will require developers to resubmit their plugins and to conform to new submission requirements. There are alternative plug-in search engines like jquer.in that take more specialized approaches, such as listing only plug-ins that meet certain criteria (e.g. those that have a public code repository). jQuery provides a "Learning Center" that can help users understand JavaScript and get started developing jQuery plugins.
jQuery was originally released in January 2006 at BarCamp NYC by John Resig and was influenced by Dean Edwards' earlier cssQuery library. It is currently maintained by a team of developers led by Timmy Willison (with the jQuery selector engine, Sizzle, being led by Richard Gibson).
jQuery has also an interesting software license history. Originally under the CC BY-SA 2.5, it was relicensed to the MIT license in 2006. On end of 2006 it was dual-licensed under GPL and MIT license. As this led to some confusion, in 2012 the GPL was dropped and is now only MIT licensed.
As of 2015, jQuery remains the most widely used JavaScript library on the Web. According to JavaScript library analytics service, Libscore, jQuery is in use on over 63% of the top million most popular sites by traffic volume. Notable sites using it include Twitter, LinkedIn, Pinterest, and eBay.


Dogma 95 Comments by Mark R. Leeper
What is Dogma 95?
My review of the BLAIR WITCH PROJECT made reference to the fact that it was very nearly a Dogma 95 film, probably without even trying. In the September 13 NEW YORKER David Denby makes the same observation. In the most recent episode of Roger Ebert's review program on TV he said that JULIEN DONKEY-BOY is a Dogma 95 film. Now a correspondent has asked me to explain my take on Dogma 95. Well, I cannot claim to be an expert, but here goes.
Back in the 1960s an issue of MAD MAGAZINE talked about audiences who went to see foreign films. Their illustration was an audience watching a film and the image on the screen was of water with one arm, limp at the wrist rising above the surface. In other words they were watching something depressing. Even then there was the idea that European art films were serious, depressing, nihilistic affairs and American films were somehow lighter. There was probably some truth to this. Most were not as glum as the MAD image would indicate though maybe Andrzej Wadja's KANAL, which takes place mostly in a sewer, might be a candidate. Roberto Rosellini's OPEN CITY is very downbeat also. It is an anti-Nazi film shot secretly in Rome while it was still occupied by Nazis. (I picture Rosellini setting up on the street like we see the title character do in ED WOOD. But when he yells "run" his film crew really had something worth running from.) American films of the post-war era like John Wayne westerns were generally lighter fare.
Flash forward to the 1990s and there is still the division. We now have computer techniques to create visuals that are spectacular. Films have never looked better. On the other hand, there are very few films of much substance. The American film industry is catering in large degree to the public who spends the most money on films. That is people from age 15 to 25. That audience tends not to like a lot of deep thought in their films. So the formula is to aim films at that range, make them dumb if necessary but very visual, and if the film is not theatrically marketable, it can go direct to cable or cassette. There are not many films of any substance being made these days by the major American studios. It is too easy to make a nice looking film without much substance that will appeal to the affluent but not well discerning audiences. Compounding the problem is that good filmmakers like Paul Verhoeven make substantial films in their own country, then get seduced by the big budgets of the American film industry and never make a film of real substance again. A set of European filmmakers have said that they are not going to make artificial special effects driven films, they are going to make films in what appears to be the tradition of Roberto Rosellini. They will follow a list of ten rules drafted by Danish filmmaker Lars von Triers:
I swear to submit to the following set of rules drawn up and confirmed by DOGMA 95:
1. Shooting must be done on location. Props and sets must not be brought in (if a particular prop is necessary for the story, a location must be chosen where this prop is to be found).
2. The sound must never be produced apart from the images or vice versa. (Music must not be used unless it occurs where the scene is being shot).
3. The camera must be hand-held. Any movement or immobility attainable in the hand is permitted. (The film must not take place where the camera is standing; shooting must take place where the film takes place).
4. The film must be in color. Special lighting is not acceptable. (If there is too little light for exposure the scene must be cut or a single lamp be attached to the camera).
5. Optical work and filters are forbidden.
6. The film must not contain superficial action. (Murders, weapons, etc. must not occur.)
7. Temporal and geographical alienation are forbidden. (That is to say that the film takes place here and now.)
8. Genre movies are not acceptable.
9. The film format must be Academy 35 mm.
10. The director must not be credited.
Films that already have been made following these conventions include BREAKING THE WAVES and THE CELEBRATION. Obviously the mystical number ten was important in the rules since even von Triers himself has never followed his own tenth rule. (Or perhaps is it just not that we know of.) THE BLAIR WITCH PROJECT, by chance, or perhaps inspired by the same concerns followed Rules 1 to 7. And that film's appeal is the immediacy of its action which is certainly one of the goals of Dogma 95.
The Dogma 95 directors are in a sense the puritans of the international film industry. This is not in the sense that they eschew sex and naughty words in their films, but they have reacted to what they see as excesses in the film industry by creating their own strict set of rules to live by apart from the mainstream. They want a more natural, less gimmicky and not by chance a less expensive mode of filmmaking. It itself is a gimmick and I am sure even the Dogma 95 filmmakers admire a great many films that break many of their rules.
Is Dogma 95 in itself a good idea? One might as well ask if Cubism is a good idea. It is a movement that will appeal to some and not to others. Most people I talk to do not like Dogma 95 films. A common objection is the use of the hand-held camera. This is not a device that a filmmaker like Rosellini used because it was not around in his time. But he undoubtedly would have appreciated the naturalism of filming with a box you hold in your hands. The over-use of hand- held cameras does lead to motion sickness in some viewers.
One thing certain is that Dogma 95 strips away from film a lot of the folderol that distracts from the theme and essence of a film. Like other forms of Puritanism it clearly is intended to elevate substance over style, which is probably a good thing. And it is not a movement that is going away after one or two films. I think it will be with us for a while at least.

 They consist of a array of pins, power, input pins, output pins and ground pins. Take note of the image in figure 1.1.
|
Figure 1.1: This explains what and where every is |
|
Power pins give a +5 volts to any wires or other devices conected to them.
Ground pins are grounded and are needed to complete a circut.
Dip Switches labeled 1 to 8 toggle the power flow through the input pins A to F respectively.
Input pins supply a +5V when the corrasponding dipswitch is on. The LED located above each one lets you know if that group of input pins has power.
Output pins are grounded and turn on when a power is supplyed to them.
Pin array is where all your circutry is done. It incorperates the power, input, output, and ground pins.
The pin array can be broken down even further into the top rail, the top half, the gap, the bottom half, and the bottom rail (Figure 1.2).
|
Figure 1.2: This explains in depth the pin array |
|
The top and bottom rails are connented horizontaly. So if power is supplied to any pin in them they all are connected. You generaly connect the +5V to the top rail and the ground to the bottom rail. From there you would distrubute the power.
The top half and bottom half are different. Their pins are connected vertically and are separated by the "Gap". This means that if power is given to a pin in the top half all the pins vertically from that pin in the top half would then have power.
The gap is a very useful part of the breadboard. It is the right space for a chip to be inserted (it also is the only place the "Virtual Breadboard" will let you put it). Since the top and bottom half's pins are connected vertically it allows you to control each pin individualy.
To illistrate how the board is wired up please see the interactive Figure 1.3

Yesterday i recieved a JIRA issue from QA that the iOS application is very slow apparently the issue was in application services(API) being very slow to perform any operation. I started to investigate in the issue and there was a use case that the user select a file then there was a 2 API that should be called to process this file to be previewed in PDF previewer, So i started to think about a way to calculate the time the process it takes starting from selecting the file untile it’s previewed. i eneded up with profiling and therfore i did some research on how to do a profiling in Xcode and i found that Xcode has an addition to unit testing it provide the ability to measure the performance of a piece of code. This allow developers to gain insight into the specific timing infotmation of the code that being tested.
Performance Testing
With performance testing you can know the average time of execution for a piece of code. Also you can define a baseline exection time. This means that if the code that’s being testd deviates from that baseline, the test fails. Xcode will repeatedly execute the code 10 times and measure the average execution time. To measure the measure the performance of a piece of code, use the “measureBlock:” API. This is one of the test cases i prepared:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
|
But what is XCTestExpectation in this block of code, Right this is a class that enable you to test Asyncronous code. The flow to test Asynchronous code is as follows, define an expectaion, wait for the expectation to be fulfilled, and fulfill the expectation when the asyncronous code finsish executing.
Then i started to run the above test in Xcode and this was the result:
Now you can edit the baseline time of execution for the performance test.

Each year, the shallow waters of Hudson Bay start to freeze around November and from mid-November until June, the bay remains largely frozen.
For the western Hudson Bay polar bear population, which is made up of approximately 935 bears, the sea ice pack becomes their hunting ground and is where they spend most of their lives hunting their primary food source, the ringed seal.
Churchill is one of the few human settlements where polar bears can be observed in the wild.
In the isolated Arctic town of Churchill, the bears wait around the shore for the sea ice to form every autumn having left their dens on the tundra surrounding the town, where the subsoil remains permanently frozen.
By autumn, it has been about four months since their last meal.
The Churchill bears are one of 19 polar bear populations in the world, and by far the most accessible due to their habitual autumnul wait on the edges of the coastal town. Churchill is one of the few human settlements where polar bears can be observed in the wild. According to Manitoba Conservation, polar bears in this area are in decline due to a three per cent loss to the extent of the ice pack every decade, and a spring ice break up occuring approximately three weeks earlier than historical records indicate. When the ice melts, the bears come ashore and fast for about four months, living on stored fat until the following winter. While the majority of bears fast for about four months, pregnant females remain on land to give birth and fast for about eight months. The changing seasonal conditions are also affecting the ringed seal, according to Manitoba Conservation, due to spring rains impacting their maternity dens.
In fall, as the ice forms, ringed seals cut breathing holes in the ice using the sharp claws on their foreflippers. These holes are kept open all winter in ice that can get up to two metres thick. The seals surface every few minutes at one of these holes, or use air pockets trapped under ice to breathe. Polar bears stalk their prey by waiting at a breathing hole, sometimes for hours or days. Weighing in at around 500kg, an adult polar bear can drag a seal from the water with its claws. But ringed seals also bask on the ice and make easy prey for the bears who use the seals’ sleep-wake pattern to slowly creep up on their prey before darting at the seal at explosive speed and killing it before it can retreat to the safety of the ocean.
The polar bear season, in October and November each year, is the largest contributor to the Churchill’s tourism, and there are a myriad of ways to explore the region at this time of year, including secluded lodges, retreats and from purpose-built viewing vehicles.


Avoiding Burnout and Increasing Happiness
by Creating Better Work-Life Balance
(I learned this the hard way.)
...or I was going to die.
Literally: “death from overwork” in Japanese.
“I’ll sleep when I’m dead.”
“I can’t hang out tonight; I’m working on this really important deadline for work.”
Compared to the same period of time at 40 hours a week.6
Because that's how impaired your performance is.9
But don't give up hope just yet.
We can’t sacrifice our long-term well-being for short-term gains.
Fixing the way we work is worth the effort. Remember…
(Let’s be friends on Twitter.)

Zone Launcher Makes It Easier to Access Your Apps with One Swipe
by George KamauIf you’re on the lookout to experiment with new custom launchers for your Android device, then Zone Launcher is one to download. Android phones come with their default launchers and the Google Play Store has a ton of launcher apps you can choose that offer customization options to your liking.
If you’re trying to dip your toes in new launchers, check out Zone Launcher.
Zone launcher works by giving you an easier way to access your apps with one swipe from whatever app you are in – this removes the extra step of going back to the Home Screen and swiping up to get the app you want.
The app works like the Smart screen found on Infinix, TECNO and OPPO devices or Samsung Edge that gives users quick access to apps and actions from any screen on your Android app.
How it works
Once downloaded, you can bring up the app by swiping from either the left or right side of your phone and then hover the interface across the alphabet list were hovering on a letter will pop up apps that start with that letter. To select an app, you hover over it and let go to launch it.
You can customize the app by adding “Zones” with select apps either social media or productivity or streaming depending on your choice. For each zone, you can add your favourite apps and choose to colour code them.
Other features include customizing background blurring, opacity change effects and support for launching actions.
I’ve been using the app together with Nova Launcher to quickly access my social media apps while I’m browsing the web or when switching between Instagram and Twitter.
I’m pretty sure you’ll love the convenience of not heading to the app drawer or home screen each time you want to open an app. Zone Launcher comes in handy especially if you’re a huge multitasker.
