The cells_grand_summary()
function is used to target the cells in a grand
summary and it is useful when applying a footnote with tab_footnote()
or
adding custom styles with tab_style()
. The function is expressly used in
each of those functions' locations
argument.
cells_grand_summary(columns = TRUE, rows = TRUE)
| columns | The names of the columns that are to be targeted. |
|---|---|
| rows | The names of the rows that are to be targeted. |
A list object with the classes cells_summary
and location_cells
.
When using any of the location helper functions with an appropriate function
that has a locations
argument, multiple locations can be targeted by
enclosing several cells_*()
helper functions in a list()
. The following
helper functions can be used to target cells (roughly in order from the top
to the bottom of a table):
cells_title()
: targets the table title or the table subtitle
depending on the value given to the groups
argument ("title"
or
"subtitle"
).
cells_stubhead()
: targets the stubhead location, a cell of which is
only available when there is a stub; a label in that location can be created
by using the tab_stubhead()
function.
cells_column_spanners()
: targets the spanner column labels, which
appear above the column labels.
cells_column_labels()
: targets the column labels.
cells_row_groups()
: targets the row group labels in any available row
groups using the groups
argument.
cells_stub()
: targets row labels in the table stub using the rows
argument.
cells_body()
: targets data cells in the table body using
intersections of columns
and rows
.
cells_summary()
: targets summary cells in the table body using the
groups
argument and intersections of columns
and rows
.
cells_grand_summary()
: targets cells of the table's grand summary
using intersections of columns
and rows

Maharashtra govt formation: Shiv Sena scared of BJP 'poaching' its MLAs, says Congress
Despite the BJP and the Shiv Sena in a comfortable position to jointly form government in the state, they have been warring over sharing the chief minister's post.
Amid the standoff between the 'Mahayuti' constituents over government formation in Maharashtra, the Congress has accused the BJP of being "morally corrupt", if its ally Shiv Sena feels scared that the Amit Shah-led party will "poach" its MLAs and asked whether this alliance has a moral right to form government in the state.
The BJP and Shiv Sena contested the recently-held state Assembly polls under the aegis of 'Mahayuti' (grand alliance) along with some smaller allies.
"Shivsena is an alliance partner of BJP and part of Mahayuti. If it feels scared that BJP will poach their MLAs, then we can very well understand how much BJP is morally corrupt and why we must save Maharashtra from them. Does Mahayuti have moral rights to form govt now?" Maharashtra Congress general secretary Sachin Sawant said in a tweet on November 7.
However, despite the BJP and Sena in a comfortable position to jointly form government in the state, they have been warring over sharing the chief minister's post.
The Shiv Sena wants the post to be shared for two- and-half years each on a rotation basis, but the BJP has rejected such an arrangement.
Some BJP leaders and its allies of late claimed a section of Shiv Sena leaders were in touch with Chief Minister Devendra Fadnavis -- apparently to switch sides.
Taking a dig at the BJP, Congress national spokesperson Sanjay Jha said resorts in places near Mumbai, like Khandala, Alibaug, Matheran and Madh Island may soon be blocked.
"But given the money they have, the BJP should also consider Maldives, Bahamas, Bermuda and Pattaya," he quipped.
Without naming the BJP, NCP's Maharashtra unit chief Jayant Patil also claimed that some MLAs were being lured.
"Some MLAs are being lured now. But in case anyone defects (to the BJP's camp), other parties will come together and defeat him/her (in bypoll)," Patil told reporters here.
He, however, said the NCP MLAs were not among those who were being lured.
"Those who wanted to switch sides, left (the NCP) before the election. The ones elected (on NCP's tickets) have people's faith in them and we are ready to sit in the opposition," he said.

_The_Replacements_ (PG-13) ** (out of ****)
Going into _The_Replacements_, one knows exactly what one is going to see: a team of misfit football players comically getting their act together for the big game, during which they enjoy their moment of glory. And, indeed, the only real surprise of this comedy is just how content director Howard Deutch and writer Vince McKewin is with strictly following expectations, not serving up one single deviation from the given formula.
It's for that very reason that I wouldn't be surprised if _The_Replacements_ became a substantial late-summer hit; everything about it is calibrated just so for broad audience "satisfaction." Consider, first, the characters that make up the replacement squad for the fictional Washington Sentinels. There is Daniel Bateman (Jon Favreau), a violence-prone cop who speaks in a growl--leading to lots of easy physical gags involving his penchant for tackling. There's Clifford Franklin (Orlando Jones), the wisecracking black guy.  Rhys Ifans' placekicker Nigel is basically a replay of his popular character in _Notting_Hill_, a scruffy, layabout Welshman. But with all these caricatures, there has to be a straight man, and here he's in the form of a cliché--quarterback Shane Falco (Keanu Reeves), who cannot quite live down choking in the crucial final moments of his last college game.
Will Coach Jimmy McGinty (Gene Hackman) whip these boys into shape? Can Shane find redemption and deliver when put in a similarly nailbiting situation? Will there be a crucial injury before the last game is through? Should there be any doubt? But before _The_Replacements_ reaches its foregone conclusion, there is the expected stream of hijinks. The replacements get into a bar brawl with the on-strike players. Head cheerleader Annabelle (the warm and winning Brooke Langton, who deserves more big-league roles) must preside over a pep squad trained in a different type of spirit-raising--lapdancing. Clifford leads his teammates in a rousing electric slide to "I Will Survive." Yes, these set pieces are engaging enough to hold the attention. What they aren't, however, are original or distinctive enough to hold long in the memory.
Which is _The_Replacements_'s ultimate failing--the film is competently done (though a few of the actors, namely Favreau, are constricted by one-note roles), but there's nothing to distinguish it from the pack of sports comedies and feel-good underdog stories. Perhaps that's exactly what the masses are asking for, but it's discouraging that Deutch and his crew didn't even try to bring anything more to the tired game.

I have considered to use a combination of an Arduino Uno and RPi for my Home Automation Project.
After vigorous research(Googling of cause) on how I am to interface the two, I came to a conclusion that using I2C was the best option as compared to using UART(which required Logic Level Switching as the RPi runs on 3V3 and Arduino on 5V), or as compared to USB communication.
The idea is to have the Arduino doing all Analogue detections and calculations such as a temp sensor, LDR, IR and etc. And also including extra GPIO's for additional controls.
Now back to the I2C, in this case the RPi will function as the Master and Arduino as the Slave.
Hint: The RPI is running on 3V3 while the Arduino is running at 5V. I read some tutorials where they used a level shifter for the I2c communication. This is NOT needed IF the RPI is running as master and the Arduino is running as slave device. You can use the I2C bus without level shifter as only the master will push the data line high!
Make sure your Raspberry Pi is connected to the internet when installing the drivers.
The new Raspbian distro already have the I2C driver installed but they are disabled by default.
We need to download additional drivers and enable I2C.
[sourcecode language="bash"]
sudo apt-get update
sudo apt-get install i2c-tools
[/sourcecode]
Note : The installation could take a few minutes to do, depend on how busy the server is.
Now add a new user to the i2c group:
[sourcecode language="bash"]
sudo adduser pi i2c
[/sourcecode]
Install the python-smbus python module:

Most auto-complete textboxes may have a reverse effect on end-users. Instead of helping them get things done faster, they get irritated by design flaws made by the programmer. (Admittedly, I've made such design flaws too.)
I got to learn this lesson when designing my first auto-complete edit control, found here[^]. Although it seemingly looks intuitive, I forgot to consider the fact that what if the end-user wanted to type just 'ap' but the 'ple' appears out of nowhere? This means that the end-user would then have to hunt for, and press the delete key.
After seeing how GMail made its auto-complete, I took the idea and implemented my own version of the auto-complete control.
Auto-complete textbox control:
The important event that will fire whenever the user press any key is onkeydown
. The onkeydown
event handles all the normal character input and is in charge of creating the auto-complete list. It also handles keys like 'up', 'down' and 'enter'.
Using the JavaScript regexp()
object, the script will run through the array containing the keywords and match them one by one. After which, a DIV
will be created dynamically using document.createElement()
. Finally, when the user presses the 'Enter' key, the DIV
will be detached and the input box updated.
The user can also select the options using the mouse. This is done through a three events: onmouseover
, onmouseout
, and onclick
.
Firstly, include the .js file into your script:
<script language="javascript" type="text/javascript"
src="actb.js"></script>
Next, create an array (in JavaScript) containing the keywords:
customarray = new Array('apple','pear','mango','pineapple',
'orange','banana','durian', 'jackfruit','etc');
Apply the widget to your using javascript:
actb(document.getElementById('textbox_id'),customarray);
And you're done!
This auto-complete edit control has some customizable features:
/* ---- Variables ---- */
this.actb_timeOut = -1; // Autocomplete Timeout in ms (-1: autocomplete never time out)
this.actb_lim = 4; // Number of elements autocomplete can show (-1: no limit)
this.actb_firstText = false; // should the auto complete be limited to the beginning of keyword?
this.actb_mouse = true; // Enable Mouse Support
this.actb_delimiter = new Array(' ',','); // Delimiter for multiple autocomplete. Set it to empty array for single autocomplete
this.actb_startcheck = 1; // Show widget only after this number of characters is typed in.
/* ---- Variables ---- */
/* --- Styles --- */
this.actb_bgColor = '#888888';
this.actb_textColor = '#FFFFFF';
this.actb_hColor = '#000000';
this.actb_fFamily = 'Verdana';
this.actb_fSize = '11px';
this.actb_hStyle = 'text-decoration:underline;font-weight="bold"';
/* --- Styles --- */
this.actb_keywords = new Array();
The styles are pretty self-explanatory; tweak the values for best results for your own website. Firstly, the variable actb_timeOut
controls how long the auto-complete list's timeout should be (i.e., after x ms, the list will disappear). By default, it is set to -1, which represents no timeout.
Next, the variable actb_lim
limits the number of elements the list will show, to prevent over-spamming. If you do not want to set any limit, set it to -1.
Thirdly, the actb_firstText
variable determines whether the match with the keywords-array should only start from the first character or if the match can be any arbitrary match within the keyword. For example, if firstText
is set to true, then a given string "ello" will match with "hello".
Also, the actb_mouse
variable determines whether the control should respond to mouse events. Mouse support works when user clicks on the auto-complete list that appears.
The actb_delimiter
variable allows for the much requested multiple auto-complete feature. Set a custom delimiter, or even multiple delimiters, like semi-colon (;) or comma (,), and the engine will complete words separated by the given delimiter.
Lastly, actb_startcheck
controls the number of characters that must be typed in before the textbox will display the control. Thanks to flyasfly for this suggestion.
As of version 1.3, all of the above mentioned are public variables. This can be useful in emulating controls like Google Suggest. When you apply the control to your textbox using the actb function, it returns an object.
Changing the autocomplete list
obj = actb(document.getElementById('textbox_id'),customarray);
// ... after some time ...
obj.actb_keyword = new Array('this','is','a','new','set','of','keywords');
Multiple auto-complete textboxes
obj = new actb(document.getElementById('textbox_id'),customarray);
obj2 = new actb(document.getElementById('textbox2_id'),customarray2);
Multiple textboxes (different options)
obj = new actb(document.getElementById('textbox_id'),customarray);
obj.actb_mouse = false; // no mouse support
obj2 = new actb(document.getElementById('textbox2_id'),customarray2);
obj2.actb_startcheck = 2; // start actb only after 2nd character
Thank you to all of you who has supported, modified, and offered your suggestions to the control! I'm extremely apologetic for the inactiveness of this project because of schoolwork etc. However, I still try my best to work on it whenever anyone has a new feature request!
This control will be, from effect of version 1.1, published under Creative Common License [^]
actb_startcheck
the number of characters that start the widget contro. Thanks to flyasfly for suggestionactb_keyword
) becomes a public variable, so it can be modified from the parent scriptactb_removedisp()
cannot be executed properly)
actb_timeout
now works fine with mouse support on
clientHeight
which apparently Mozilla does not support. Thanks Cameron Smith for pointing out.


TLDR: I bought an $4.99 app I should have bought 5 years ago which ended up treamendously improving my phone’s battery life and my life as well. Don’t try to be frugal on everything.
The regret
Ever regret not to purchase something while it actually brings way more positive impact than your expectations after you pulled the trigger finally?
Franco Kernel Updater is certainly one of it to me. Android enthusiast must be familiar with this famous Kernal developer who aims to boost phone’s battery life greatly.
While the Franco Kernal only supports dev-friendly phones like the Google Nexus series and One Plus series, the phones I used for the past few years are all in the support list. Couldn’t believe I didn’t get it until now.
Battery health at 85%
I’m using the mighty One Plus 3 which is a 1.5 year-old phone and it still going strong, I really see no need in replacing it but there is 2 issues I’m currently facing. Relatively sub-par camera compared to crazy-ass 3 lenses phone(I can live with that) and the declining battery capacity which is critical to me.
There is no way for me to source a factory battery in Singapore and I do not want to give the beloved phone up just because of battery life. Looking at the solution at system level and tried some tricks, battery life is still draining like waterfall.
I recalled the legendary Franco Kernel updater and finally pulled the trigger, this is when the magic happened.
Instant battery boost, amazingly.
The app automatically download the kernel, flash and reboot the phone smoothly. I wasn’t expected everything will be done in one-go and was quite nervous since things like this could go wrong and I don’t have latest backup. A plus point for the smooth installation!
I’ve been using this app for a few days and the battery life improvement is tremendously noticeable. Got almost 5 hours of On-Screen-Time out of the 1.5 year-old 3000mah battery, could have been easily gone up to 6 hours if this is a brand new phone. Oh man, god knows how much I’ve missed for skimping on a $4.99 app.
The configuration is simple
I’m not gonna make a full introduction for this awesome app but you can help yourself over link below(no referral bonus unfortunately):
https://play.google.com/store/apps/details?id=com.franco.kernel&hl=en_SG
They have tons of features but I only make use of the “Battery life labs”. I have same performance(never wanted to sacrifice this for but way more battery juice for the setting below:
- Underclock the CPU by 25%.
- Underclock the GPU.
- Applied 20% lower max brightness.
- Installed Naptime and enabled Aggressive Doze. Awesome idle time from this app, simply a must-get.
That’s all I did and all the setting will be loaded upon every reboot, so it is kind of a one-time setup. Add the BetterBatteryStats or other battery performance app to monitor the changes.

We've tried several times to define Software Carpentry's aims and content in terms of the questions that researchers ask (see for example our competence matrix and this post mapping eight questions to our current content). Our latest attempt is crowd-sourced with a small 'c': the people who are taking part in the first round of our online study group for instructors and would-be instructors put together their own lists of questions, along with the answers they'd expect from novice, intermediate, and expert scientific programmers. I've consolidated those lists into 25 questions, which I'd like to boil back down to no more than 10. If you'd like to take a crack at doing that, please post your suggestion as a comment, and I'll send you a Software Carpentry t-shirt if we use it.

- How can I fix this program?
- How can I make this program easier to understand?
- How can I keep track of what I've done?
- How can I figure out how someone else's program works?
- How can I avoid putting bugs in my programs in the first place?

Lisa Left Eye Lopes came into the spotlight with the popularity of TLC. A group to this day is the only girl group to go platnium, the number one girl group in American, and number two to the Spice Girls Worldwide. Without any of the members TLC would not have the legacy it has today. An Important part of that legacy is Left Eye. As the rapper of the group she wrote all her parts, but she was not only the rapper of the groups she many times seems to be the visual artist of the group. Something a lot of people may not know. Chilli and T-boz themselves said that she designed all the stage set-up for their concerts. While many only know her TLC, she released an amazing solo album. Unfortunately her record company did not release "Supernova" in the US(meaning it isn't avaliable for streaming to this day in the US). I would describe this album as a experimental(for the early 2000s) and a bit eclectic. Before her passing she was working on releasing her second solo album.
Before her passing she shared her vision of opening a youth center in Honduras with her famliy. Although her life ended suddenly and tragically, her vision came true posthumously. After her passing her family started the Lisa Lopes foundation, which gives youth in need with resources to help them. During her time here there were many literacy programs in Honduras she promoted. Locally, she opened up an affordable recording studio for the people in her community. She also mentored young budding artists. After winner "Who wants to be a millionaire" she donated her winnings to "The Village Foundation" charity.
She on lives on through her music, art, and efforts to better peoples lives. Her family, friends, and fans, keep her legacy alive. To read more about this stellar supernova click Here

Shodai handed first tourney loss
FUKUOKA – Hometown favorite Kotoshogiku picked up his first win of the Kyushu Grand Sumo Tournament on Thursday, defeating previously unbeaten overnight leader Shodai and pulling him back to the pack.
The No. 9 maegashira briefly turned back the clock to his ozeki days as he quickly shoved out his No. 10 opponent, leaving the title race wide open as injuries continue to thin out the ranks at Fukuoka Kokusai Center.
Sekiwake Tochinoshin and the other joint overnight leader, No. 16 Wakatakakage, both withdrew from the 15-day tournament earlier in the day, joining yokozuna Kakuryu, ozeki Goeido and No. 3 Tomokaze on the growing injury list.
All-time championship record-holder Hakuho (4-1) now headlines a group comprising mostly lower-ranked rikishi leading the race for the last Emperor’s Cup of the year that includes Shodai, komusubi Asanoyama, No. 2 Meisei, and No. 6 Enho.
The yokozuna pounced on No. 2 Myogiryu (2-3) to keep his prospects of winning his first makuuchi title as a Japanese citizen.
In other bouts, the upsets continued as ozeki Takakeisho (3-2) and Takayasu (2-3) again crashed down.
Takakeisho tried to push out No. 3 Takarafuji (2-3), but was shoved aside and fell forward to the clay.
Takayasu (2-3) had Meisei (4-1) on the ropes for most of their lengthy bout, but was eventually pulled down as he tired out and struggled to keep his balance.
Mitakeumi (2-3) was defeated by No. 1 Okinoumi (2-3) and fell to his third loss. The sekiwake had Okinoumi in a headlock and tried to throw the maegashira down, but was turned around and driven out.
The komusubi-ranked wrestlers squared off against each other on Day 5, with Asanoyama (4-1) and Abi (2-3) emerging victorious with respective wins over Hokutofuji (3-2) and Endo (1-4).
Asanoyama blasted Hokutofuji with a hard initial hit and steamrolled him over the straw, while Abi drove out Endo with a thrusting attack.
Among the rank-and-file, Enho (4-1) downed No. 5 Aoiyama (3-2) to the crowd’s delight. The top division’s lightest wrestler snagged Aoiyama’s arm and yanked him down, having held his ground against the Bulgarian who is more than twice his weight.
No. 11 Chiyotairyu (3-2) and No. 12 Takanosho (2-3) celebrated their respective birthdays with Day 5 wins.
Earlier Thursday, Tochinoshin (2-3) pulled out with a right rib cartilage fracture sustained in his Wednesday bout against Takarafuji.
The injury-plagued Georgian will likely miss his chance to reclaim the sport’s second-highest rank, needing at least 10 wins over the 15-day meet to secure an automatic return to ozeki.
Wakatakakage forfeited his bout with No. 13 Kagayaki (3-2) and saw his perfect top-division debut come to an unfortunate end.

'Hello World'


For the theme of my dataset, I choose the music of artist Adele. Through lab tasks and extra work I have accumulated a wide variety
of transcribed scores, MEI files, metadata and interesting analysis all available below.
Notated Data
To access the notated pieces that I transcribed, listen to the exported WAV files (where available) and download the MusicXML or MuseScore files, click on the links below:
To accompany my transcribed documents, I carried out some analysis on the pieces using jSymbolic. Below you can access the raw CSV data
or you can access an annotated, edited Excel file where I put some of the analysis into context and made some comparisons between the songs.
Using the Python library "music21", I created piano roll and histogram graphics for all four pieces that can be viewed here.
Other Material
Part of this project involved using computer tools to investigate music as sound and digital audio. This involved tasks such as creating metadata, spectrograms, chromagrams and investigating similarity and computer transcription.
Below is evidence of my work for each of these lab tasks (due to copyright limitations of Adele's music in acoustic form, these tasks were completed with music from freemusicarchive.org):
In Week 8's task, I identified the most important technical / non-technical metadata for three pieces of music sourced online and created spectrograms and waveform images for each song. I also then compared these two visualisations
in order to evaluate advantages of time-frequency analysis over waveform based analysis. I have compiled my metadata, images and files in this document.
In Week 9's task, I created Spectrograms, Mel Frequency Cepstral Coefficient and Chromagrams for three tracks. The second part of the task involved me comparing raw features in Python to produce and compare histograms for each song.
The images, raw data and CSV files can be accessed here.
In Week 10's task, I firstly created a similarity matrix for a selection of songs from different genres and also plotted a graph showing the A note occurance against the C note occurance (with each genre being shown as a different shape) based on Chroma values:
I then sourced a MuseScore composition for ABBA's "Dancing Queen" to test out the accuracy of automatic, computer transcription. My results and analysis can be found here
As an extra bit of analysis, using Python I made a features plot for the four Adele songs I transcribed which plots all the notes present against the time. I also created Mean Chroma Feature graphs showing the number of notes present at the time 456.
These visualisations can be seen here.

Austin Powers: The Spy Who Shagged Me (1999)
Director: Jay Roach Cast: Mike Myers, Heather Graham, Michael York, Robert Wagner, Seth Green, Mindy Sterling, Verne Troyer, Kristen Johnston, Rob Lowe Screenplay: Michael McCullers, Mike Myers Producers: John S. Lyons, Demi Moore, Mike Myers, Jennifer Todd, Suzanne Todd Runtime: 95 min. US Distribution: New Line Cinema Rated PG-13: sexual innuendo, crude humor
Copyright 1999 Nathaniel R. Atcheson
I am a fan of the original Austin Powers, and I'm also a fan of Mike Myers. I don't know much about him, but he seems like a really down-to-earth guy, one of those comedians who doesn't find it necessary to make a fool of himself every time he appears before a live studio audience. I'm glad to see that he's finally found his crowd-pleasing niche; though most of his films have found their audiences on video, Austin Powers: The Spy Who Shagged Me is likely to be the first massive box office success of Myers' career (with the exception of Wayne's World, which doesn't count for various reasons).
I liked AP2, but not as much as I liked the original. My reasons for this should not come as a surprise: too many elements are rehashed or expanded from the first film, there are sizeable gaps in the laugh-flow, and there is way too much toilet humor. The story is goofy and dopey enough to carry itself through the slow sections, and so I never found myself completely bored.  I recommend the film, but I miss the excrement-free environment and hokey originality of the first movie.
However, I think I like the story behind this one better. It has a kind of insane genius about it that makes it entertaining even when there aren't many laughs. Myers also does the right thing by giving Dr. Evil what seems like more screen time than Austin himself. (That also makes me wonder if the series shouldn't be named after the villain.) The basic structure revolves around Dr. Evil -- he goes back in time to steal Austin's mojo. After drinking the mojo, Dr. Evil becomes much more hip, and even has a one night stand with Frau Farbissina (Mindy Sterling). Austin, meanwhile, works to recover his mojo with the help of Felicity Shagwell (the luminous Heather Graham, looking happy to be in an Austin Powers movie). Little does he know that Dr. Evil has new evil cohorts: Fat Bastard (an unrecognizable Myers in an enormous prosthetic suit), and Mini-Me (Verne Troyer), a robot version of Dr. Evil, one-eighth his size.
AP2 is a rare example of a comedy that uses subplots in the right way. Just before things get dull, the scene switches to any one of the three or four subplots, and audience interest in the film is held through the end. The best subplot is certainly the relationship between Dr. Evil and Mini-Me; Troyer is absolutely wonderful as the mute little monster, and Dr. Evil's love for his diminutive pet is actually kind of touching in a sarcastic sort of way. This also adds a new dimension to Dr. Evil's biological son, Scott Evil (Seth Green). Green is a very funny young actor, and the rivalry between him and Mini-Me is quite effective. Mindy Sterling, reprising her role from the first film as the crazy German lady, thankfully is given more screen time here. And Rob Lowe does a perfect imitation of Robert Wager, playing the young version of Number Two.
There's no doubt that AP2 shines in several scenes with inspired brilliance. The two best sequences really can't be described in words, but those who have seen the film will remember the way various people all over the world describe Dr. Evil's phallic space ship as it blasts off. And Myers' love for these characters and this series keeps the film from ever feeling perfunctory or dull. But some scenes go way too far: everything with Fat Bastard, for instance, is not funny, and simply disgusting (laughing and cringing are two separate reactions altogether).
I had the distinct sense of deja vu all through AP2, as if Myers had been afraid to explore new territory. I can't say I blame him; it would have been a mistake to seriously change the look and feel of this sequel. But it lacks the discovery and newness of the first film, and so it comes off almost as outtakes from the original, rather than a new movie altogether. Don't get me wrong: Myers has made a funny picture. And, seeing as how a third installment in this series is inevitable, I have high hopes that Myers will find an all new angle on his series and exploit it into oblivion.

Cocaine |
(powder / crystals) |
Ok, one night I was with a couple friends at their apartment smoking some kind bud. And I guess the topic of doing coke came up (I was later told that I had brought it up). Staci has done it many times before, Shaun only a couple. So anyways, Staci said she would try to get some.
So the next day I go back to their apartment and they have half an 8-ball. Sixty bucks for a bag that small??!! Jesus H Christ! So anyways, Staci and I do a key bump, while Shaun says he is gonna wait until after he eats. When I snorted the bump, there were like these chunks stuck in my nose. Well anyways, we went to get something to eat, the whole time being very attentive to my body and any changes that might occur (even though it was only a 'key bump'). Nothing really unusual. Maybe a little energetic.
So we get back to the apartment and after 5 minutes we start doing it. The old 'What am I doing??' thought came to mind but I just blocked it out. We each took turns doing a line every couple minutes or so while we played Street Fighter II on the Playstation.
Maybe after a couple minutes I felt a little more energetic. I could definitely feel its effects, but it was not like I had heard or had hoped.  Bad, but not too bad. Tastes like you just chewed up and swallowed an aspirin. After an hour all the coke was gone. Shaun and I kept saying 'What?? This is it?? Definitely overrated.' while Staci was on the phone trying to get more. She said it worked on her good, although one could not tell a difference just by looking at her.
Either we did not do enough, the stuff we did was not strong enough, or some people just do not get affected as easily, but we eventually ended up going to get more. Shaun and I are very analytical people, always trying to analyze anything and everything while stoned (as I am sure a lot of people do.)I decided not to do anymore because I did not think it would really do anything plus the nasty bitterness in the back of the throat feeling, but eventually ended doing more hoping it WOULD do something. Of course it did no more than keep me alert and somewhat energetic, but that's it.
I did notice I was getting a little annoyed when Shaun kept scraping the remaining coke into a pile over and over and over )And it is hard for me to get annoyed). I also noticed I did not talk any more than usual, as opposed to Staci and Shaun who were talking constantly about nothing, which also annoyed me. We had some kind bud to do, and I was glad to do it for that is something I could actually feel. It calmed me down and immediately got rid of the anxious feeling I had on coke.
All in all, I just gotta say coke is definitely not worth it to buy or for that matter do, unless of course it is your first time and you want to see what it is like, and you don't have to pay for it. Who knows? It may be different for you. But if you have heard and seen as much hype as I have on the stuff and eventually do it....you will see for yourself. You might be in for a big let down.
Of course, like I said before, maybe the stuff we did was not as good as it could have been. But I now see how cocaine can ruin someone's life. It ruins it by making them spend their money over and over again trying to make the damn stuff work!!

Hey, it's the day after I've written my final univerisity exam. I just have a semester pending now that I'll be spending at my internship. I'm due to join on Jan 3, 2021 and am looking forward to finally getting my hands on some production software.
Since I have some downtime, there's a couple of things I'd like to do.
These are the things I'm going to be working on the coming week and a half.

India climbs one spot to 129th in 2019 human development index: UNDP
In India, 27.1 crore people were lifted out of poverty from 2005-06 to 2015-16, UNDP India resident representative Shoko Noda said
by Press Trust of IndiaIndia climbed one spot to 129 among 189 countries in the 2019 human development index, according to a report by the United Nations Development Programme (UNDP).
In India, 27.1 crore people were lifted out of poverty from 2005-06 to 2015-16, UNDP India resident representative Shoko Noda said.
India ranked 130 last year. The steady progress was due to nearly three decades of rapid development, which had seen a dramatic reduction in absolute poverty, along with gains in life expectancy, education, and access to health care, she said.
As per the HDI, no other region had experienced such rapid human development progress.
South Asia was the fastest growing region witnessing 46 per cent growth during 1990-2018, followed by East Asia and the Pacific at 43 per cent.

Overview
Decentralized Finance (DeFi) emerging on Ethereum is showing promising result towards during a disintermediated financial system. But most protocols exist today lack a systematic way for managing risk and handling system insolvency. In this paper, we will discuss what is the common pitfall for solvency management in DeFi nowdays, and proposed that some constraints can be relieved. We will use balance sheet as tool, and explain how coverage ratio and quick ratio can be used for risk assessment of the system. Lastly, we will combine all these and propose a protocol that can unify all DeFi protocols (including but not limited to: token swapping, lending, stablecoins) into one system and thereby significantly increase capital efficiency.
For this project, we would like to lay out the design of Decentral Bank - an autonomous financial protocol constructed on public, decentralized blockchain (e.g.: Ethereum).
Decentralized Finance
While we have a comprehensive survey paper discussing what is DeFi, it is too pedantic to put on the project website. Instead, we direct interested readers to this video on youtube to understand what decentralized finance is:
A sample DeFi project, Uniswap, can be accessed here.
Our Design
Existing DeFi protocols can be boardly be classified into Token Swapper (Uniswap [1], Balancer [2] and Curve.fi [3]), Money Market (Compound [4] and Aave [5]), Stablecoins (MakerDAO [6]). Decentral bank's design allows integrating all the above protocols into an all-in-one, single system.
Besides, theorotical development is needed as our protocol since it doesn't use Constant Function Market Maker [7] and two-asset model [8] for token swapping. Instead, Decentral Bank relies on single token's coverage rate for defining the curvature.
We will use balance sheet as tool, and explain how coverage ratio and quick ratio can be used for risk assessment of the system, eventually unify all DeFi protocols (including but not limited to: token swapping, lending, stablecoins) into one system and thereby significantly increase capital efficiency.
The system can be described as Actors performing actions against Pools. Actors can be classified into 5 groups:
Liquidity Providers. They provide capital to the system, expecting rewards (i.e.: dividend) to be paid upon withdrawal.
Casual Users. They perform actions (e.g.: swap, borrow) on the system. They can access the system services with fees.
Arbitrageurs. They are paid for helping the system to restore equilibrium via swapping.
Stakers. They are governance token holders who stake their governance tokens, expecting rewards (i.e.: system surplus) to be paid upon unstake.
Keepers. They are paid for helping the system to liquidate bad loans (that are close to or already default).
AMM Design
In traditional exchange models (i.e.: order book), liquidity is provided by market makers who place limit orders in the order book. When a large buy order is being executed, the average price will increase as the order needs to sweep through higher part of the order book to source for sufficient liquidity. This phenomenon is called price slippage.
In a token swapper model, the order book no longer exists, and the liquidity provider has given up their right to set a price. It becomes the system’s sole responsibility to determine a proper algorithm for setting the exchange rate and slippage. As a result, we need to determine an algorithm that has a similar effect as price slippage to penalize large orders. This algorithm is known as an automated market maker.
Our proposed AMM will be used for digital asset exchange. To obtain the price information, price oracles such as Chainlink [9] will be used and the AMM determines the price slippage. Upon token swapping, liquidity for one token is improved while it is reduced for the other token. This increases the solvency risk for the system since the under-covered position is exposed to exchange rate risk. From this perspective, it is reasonable to establish price slippage as a function of coverage ratio. To our knowledge, we are the first to link up AMM with system's solvency risk, enabling single-asset market model and open liquidity pool.
Price slippage curve. Price slippage curve maps coverage ratio to such that its slope will become the price slippage. The price slippage curve should satisfy the following properties:
- is continuous
- is decreasing
- is convex
- is continuous
There are many choices for . The one that our system will use:
where $a$ and $b$ are adjustable parameters.
