| void calibrate_accelerometers | ( | void | ) |
Function for calibrating the accelerometer biases.
This function is used to calibrate the biases of the accelerometers in the IMU and requires the users to place the IMU into at least three different orientations. The calibration method is based upon the calibration algorithm described in the paper Calibration of the Accelerometer Triad of an Inertial Measurement Unit, Maximum Likelihood Estimation and Cramer-Rao Bound, but does only calibrate the accelerometer bias.
Before the calibration is started the flags new_orientation_flag and acc_calibration_successful_flag should be set to false. Then the function should called every time new IMU-data have been read from the IMU and as long as the new flags new_orientation_flag and acc_calibration_successful_flag are false. When the flag new_orientation_flag becomes true a message should be sent to the user, which then should place the IMU in a new orientation and reset the flag. When the flag acc_calibration_successful_flag becomes true the calibration is finished and the accelerometer calibration parameters have been written into the memory of the IMU.

The estimated errors in the navigation states are then used to correct the navigation states.

The initialization is finished when the flag initialize_flag becomes false.
The initialization function first runs an initial alignment of the navigation system, where the roll and pitch are estimated from the average of the accelerometer readings.

Makes 8 soufflés
Dietary
Prepare these soufflés the day before your meal, then put them in the fridge overnight and simply bake for 10 minutes the next day – easy! They’re perfect as a veggie alternative for Christmas lunch.
Preheat the oven to 200C/180C Fan/Gas 6. Lightly butter eight ramekin dishes and line the bases with a circle of baking paper.
Peel the onion, leaving the base intact. Press the cloves into the onion, then put it in a small heavy-bottomed saucepan. Add the bay leaf and peppercorns, then pour in the milk. Heat gently until it comes to the boil, then remove from the heat and leave to stand for at least 10 minutes. Strain the flavourings from the milk and discard them.
Melt the butter in a heavy-bottomed frying pan over a medium heat. Stir in the flour and continue cooking, stirring all the time, for 1–2 minutes. Slowly pour in the warm milk and beat well using a whisk until it comes to a simmer and you have a thick sauce.
Crumble in the Stilton and add 50g/1¾oz of the grated cheddar, then continue to stir over the heat until you have a smooth sauce. Remove from the heat and beat in the egg yolks, nutmeg and thyme. Stir in the walnuts.
In a clean glass bowl, whisk the egg whites until stiff peaks form. Fold a tablespoon of the beaten whites into the soufflé mixture. Add the rest of the whites and fold in well.
Spoon the mixture into the prepared ramekins to just below the top. Bake for 15–20 minutes, or until risen and cooked. Leave to cool, then run a knife around the sides to loosen them. Line a baking tray with baking paper. Turn out the soufflés on to the prepared baking sheet, so they are bottom-side-up. If refrigerating and eating the following day, cover with cling film.
To finish the soufflés, preheat the oven to 200C/180C Fan/Gas 6. Sprinkle the remaining cheese over the soufflés and spoon a tablespoon of double cream over each one. Bake for 10 minutes, or until golden-brown. Serve.

The R community found ramazon a really helpful package.
And I actually think it is: Amazon AWS is nowadays one of the most common tools for online web applications and websites hosting.
The possibility to get your Shiny App on it just running a function make it even more desirable for the amusing R people.
Therefore, even if I developed ramazon for personal purposes , I now feel some kind of responsibility to further develop it and take it updated.
Well, to be honest: is not such a bad feeling…
A matter of packages
One of the main issues with the first release was the lack of support for multiple packages:
Shiny Apps often rely on different packages, but ramazon was only able to install the shiny package.
So I developed and just released a new version (0.2.0) able to detect and install on AWS all required packages.
You can try this new feature installing ramazon package on your R environment. Find more detailed instruction on the introductory post.
In the following lines I would like to highlights some code specs that could be interesting for the R programmers.
How ramazon lists loaded packages
This is how ramazon detects and installs al required packages.
clean the R environment
using the detach()
function, with no arguments, we are able to unload all loaded packages,
Doing this, we can be sure that no unneeded package will be installed on the AWS server.
source the app .R files
with this step, ramazon run the app source files in order to load all required packages within the current R environment.
Shiny apps can be written using:
-
two different files: ui.R and server.R
-
one unique file: app.R
ramazon can distinguish the two cases and sourcing only the existing files thank to the following conditional statement:
[code language="r”] if (file.exists(“ui.R”)){ source(“ui.R”) source(“server.R”) }else { source(“app.R”)} [/code]
.
In the hypothesis of developer using a global.R file in order to make variables available both to UI side and Server side of the app (more on the Shiny help page), one more conditional statement is introduced with consequent sourcing:
[code language="R”]
if (file.exists(“global.R”)){ source(“global.R”) }
[/code]
store all loaded packages within a data.frame
Now is time to get a list of all loaded packages.
To get this done, We use the search()
function, assigning the output to a data.frame object.
[code language="r”] environ <- data.frame(“envs” = search(),stringsAsFactors = FALSE) [/code]
the result will be something like the one below:
[code language="r”] envs 1 .GlobalEnv 2 package:stats 3 package:graphics 4 package:grDevices 5 package:utils 6 package:datasets 7 package:methods 8 Autoloads 9 package:base [/code]
As you can see, there are some unneeded values (.GlobalEnv and Autoloads), and all packages are preceded by the “package:” wording. We are going to handle this within the next paragraph.
clean the data.frame
Leveraging the grepl()
function ramazon removes all rows not containing “package”, excluding that way all non-package records:
[code language="r”] environ <- environ[grepl(“package”,environ[,1]),] [/code]
Finally, using gsub()
the “package:” wording is removed:
[code language="r”] packages <- gsub(“package:","",environ) [/code]
write the system command
The main output of the ramazon()
function, as explained in the previous post, is a bash script.
in order to install all the required packages ramazon needs to create a system command similar to the following one:
[code language="r”]
sudo su -\-c "R -e \“install.packages(c(“shiny”,“ggplot2”), repos = ‘http://cran.rstudio.com/', dep = TRUE)\"
[/code]
First of all we need to create the vector containing the needed packages.
This is obtained with a sequence of paste()
functions:
[code language="r”] packages <- paste("'",packages,"'",sep =”") packages <- paste(packages,",",collapse = “") packages <- paste(“c(",packages,sep =”") packages <- substr(packages,1,(nchar(packages)-1)) packages <- paste(packages, “)",sep =”") [/code]
finally, we have to deal with escape characters contained within the system command.
This is appropriately done using the cat()
function, that makes the lower number of manipulations on the given input.
Unfortunately, this function doesn't give any value as a result, and therefore we need to directly catch the console output and store it within the bash_script file.
Here it is the complete code for this alchemical job:
[code language="r”] sink(“bash_script.txt”, append = TRUE) message <- cat(“sudo su -\-c "R -e \"install.packages(",packages,", repos = ‘http://cran.rstudio.com/', dep = TRUE)\""") sink() [/code]
And here we are: ramazon automatically detects and install all required packages for your Shiny App on the AWS server.
getting further
Current version is somehow complete since it allows to deploy any kind of shiny app on an Amazon AWS server.
Even so there are some further possible developments:
-
I have been requested of a Windows version, and I will try to develop one. that said If anyone out there would like to help with that, just whistle!
-
ramazon is still missing some serious testing, and a log of all the console output would be really useful to help with debugging tasks.
As usual let me know if anything is going wrong &/| you have got suggestion for making ramazon a better word :)

Kohli reaches another milestone after Ishant flattens sorry Bangladesh
by Sports DeskIshant Sharma claimed a five-wicket haul as India dismissed Bangladesh for only 106, quickly seizing control at the start of the historic day-night Test at Eden Gardens.
Having hammered the Tigers in the first match of the series, India appear destined to secure a sweep after they ended a dominant opening day on 174-3, giving them a 68-run lead over their injury-hit opponents.
Ishant showed a liking for the pink ball, taking 5-22 with support from Umesh Yadav (3-29) and Mohammed Shami (2-36) as the tourists were bowled out in 30.3 overs.
Bangladesh also required two concussion replacements, with Mehidy Hasan and Taijul Islam replacing Liton Das and Nayeem Hasan respectively after they were struck on the helmet while batting.
Virat Kohli became the first Indian - and only the sixth from any nation - to score 5,000 Test runs as captain, reaching stumps on 59 not out following a gritty 55 from team-mate Cheteshwar Pujara.

Install a firewall between the DMZ and the internal network.
The DMZ has machines accessible from the Internet and is therefore subject to attack. In the event that machines in the DMZ are compromised, the firewall should protect the cardholder data environment from the DMZ. Installing a firewall between the DMZ and the cardholder data environment is a defense-in-depth measure - it offers an extra layer of security in the event that some of the network is compromised.
Install a firewall between the DMZ and the cardholder data environment. Install a firewall between the DMZ and any other internal network segment. Configure the firewalls in accordance with the firewall configuration standards. Add any new firewalls to the network diagram in the network documentation.

NEWSBEUTER(1) NEWSBEUTER(1) NAME newsbeuter - an RSS feed reader for text terminals SYNOPSIS newsbeuter [-r] [-e] [-i opmlfile] [-u urlfile] [-c cachefile] [-C configfile] [-X] [-o] [-x <command> ...] [-h] DESCRIPTION newsbeuter is an RSS feed reader for text terminals. RSS is a number of widely-used XML formats to transmit, publish and syndicate articles, for example news or blog articles. Newsbeuter is designed to be used on text terminals on Unix or Unix-like systems such as Linux, BSD or Mac OS X. OPTIONS -h Display help -r Refresh feeds on start -e Export feeds as OPML to stdout -X Clean up cache thoroughly (i.e. reduce it in size if possible) -v, -V Get version information about newsbeuter and the libraries it uses -i opmlfile Import an OPML file -u urlfile Use an alternative URL file -c cachefile Use an alternative cache file -C configfile Use an alternative configuration file -x command ... Execute one or more commands to run newsbeuter unattended. Currently available commands are "reload" and "print-unread". -o Active offline reading mode. When Google Reader synchronization mode is configured, then the list of feeds will not be loaded from Google Reader, but instead from the local cache. This makes it possible to read locally cached articles even without internet connection to connect to Google Reader. -l loglevel Generate a loglevel with a certain loglevel. Valid loglevels are 1 to 6. An actual logfile will only be written when you provide a logfile name. -d logfile Use this logfile as output when logging debug messages. Please note that this only works when providing a loglevel. -E file Export a list of read articles (resp. their GUIDs). This can be used to transfer information about read articles between different computers. -I file Import a list of read articles and mark them as read if they are held in the cache. This is to be used in conjunction with the -E commandline parameter. FIRST STEPS After you’ve installed newsbeuter, you can run it for the first time by typing "newsbeuter" on your command prompt. This will bring you the following message: Error: no URLs configured. Please fill the file /home/ak/.newsbeuter/urls with RSS feed URLs or import an OPML file. newsbeuter 2.4 usage: ./newsbeuter [-i <file>|-e] [-u <urlfile>] [-c <cachefile>] [-x <command> ...] [-h] -e export OPML feed to stdout -r refresh feeds on start -i <file> import OPML file -u <urlfile> read RSS feed URLs from <urlfile> -c <cachefile> use <cachefile> as cache file -C <configfile> read configuration from <configfile> -X clean up cache thoroughly -x <command>... execute list of commands -o activate offline mode (only applies to Google Reader synchronization mode) -q quiet startup -v get version information -l <loglevel> write a log with a certain loglevel (valid values: 1 to 6) -d <logfile> use <logfile> as output log file -E <file> export list of read articles to <file> -I <file> import list of read articles from <file> -h this help This means that newsbeuter can’t start without any configured feeds. To add feeds to newsbeuter, you can either add URLs to the configuration file $HOME/.newsbeuter/urls or you can import an OPML file by running "newsbeuter -i blogroll.opml". To manually add URLs, open the file with your favorite text editor and add the URLs, one per line: http://rss.cnn.com/rss/cnn_topstories.rss http://newsrss.bbc.co.uk/rss/newsonline_world_edition/front_page/rss.xml If you need to add URLs that have restricted access via username/password, simply provide the username/password in the following way<EMAIL_ADDRESS>In order to protect username and password, make sure that $HOME/.newsbeuter/urls has the appropriate permissions. Newsbeuter also makes sure that usernames and passwords within URLs aren’t displayed in its user interface. In case there is a @ in the username, you need to write it as %40 instead so that it can be distinguished from the @ that separates the username/password part from the hostname part. You can also configure local files as feeds, by prefixing the local path with "file://" and adding it to the $HOME/.newsbeuter/urls file: file:///var/log/rss_eventlog.xml Now you can run newsbeuter again, and it will present you with a controllable list of the URLs that you configured previously. You can now start downloading the feeds, either by pressing "R" to download all feeds, or by pressing "r" to download the currently selected feed. You can then select a feed you want to read, and by pressing "Enter", you can go to the article list for this feed. This works even while the downloading is still in progress. You can now see the list of available articles by their title. A "N" on the left indicates that an article wasn’t read yet. Pressing Enter brings you to the content of the article. You can scroll through this text, and also run a browser (default: lynx) to view the complete article if the content is empty or just an abstract or a short description. Pressing "q" brings you back to the article list, and pressing "q" again brings you back to the feed list. Pressing "q" a third time then closes newsbeuter. Newsbeuter caches the article that it downloads. This means that when you start newsbeuter again and reload a feed, the old articles can still be read even if they aren’t in the current RSS feeds anymore. Optionally you can configure how many articles shall be preserved by feed so that the article backlog doesn’t grow endlessly (see "max-items" below). Newsbeuter also uses a number of measures to preserve the users' and feed providers' bandwidth, by trying to avoid unnecessary feed downloads through the use of conditional HTTP downloading. It saves every feed’s "Last-Modified" and "ETag" response header values (if present) and advises the feed’s HTTP server to only send data if the feed has been updated by modification date/time or "ETag" header. This doesn’t only make feed downloads for RSS feeds with no new updates faster, it also reduces the amount of transferred data per request. Conditional HTTP downloading can be optionally disabled per feed by using the "always-download" configuration command. Several aspects of newsbeuter’s behaviour can be configured via a configuration file, by default $HOME/.newsbeuter/config. This configuration file contains lines in the form "<config-command> <arg1> ...". The configuration file can also contain comments, which start with the # character and go as far as the end of line. If you need to enter a configuration argument that contains spaces, use quotes (") around the whole argument. It’s even possible to integrate the output of external commands into the configuration. The text between two backticks ("`") is evaluated as shell command, and its output is put on its place instead. This works like backtick evaluation in Bourne-compatible shells and allows users to use external information from the system within the configuration. Searching for articles is possible in newsbeuter, too. Just press the "/" key, enter your search phrase, and the title and content of all articles are searched for it. When you do a search from the list of feeds, all articles of all feeds will be searched. When you do a search from the article list of a feed, only the articles of the currently viewed feed are searched. When opening an article from a search result dialog, the search phrase is highlighted. The history of all your searches is saved to the filesystem, to \~/.newsbeuter/history.search. By default, the last 100 search phrases are stored, but this limited can be influenced through the "history-limit" configuration variable. To disable search history saving, simply set the history-limit to 0. CONFIGURATION COMMANDS always-display-description (parameters: [true/false]; default value: false) If true, then the description will always displayed even if e.g. a content:encoded tag has been found. (example: always-display-description true) always-download (parameters: <rssurl> [<rssurl>]; default value: n/a) The parameters of this configuration command are one or more RSS URLs. These URLs will always get downloaded, regardless of their Last-Modified timestamp and ETag header. (example: always-download "http://www.n-tv.de/23.rss") article-sort-order (parameters: <sortfield>[-<direction>]; default value: date) The sortfield specifies which article property shall be used for sorting (currently available: date, title, flags, author, link, guid). The optional direction specifies the sort direction ("asc" specifies ascending sorting, "desc" specifies descending sorting. for date, "desc" is default, for all others, "asc" is default). (example: article-sort-order author-desc) articlelist-format (parameters: <format>; default value: "%4i %f %D %6L %?T?;%-17T; ?%t") This variable defines the format of entries in the article list. See the respective section in the documentation for more information on format strings (note that the semicolon should actually be a vertical bar; this is a limitation in AsciiDoc). (example: articlelist-format "%4i %f %D %?T?;%-17T; ?%t") auto-reload (parameters: [yes/no]; default value: no) If enabled, all feeds will be automatically reloaded at start up and then continuously after a certain time has passed (see reload-time). (example: auto-reload yes) bind-key (parameters: <key> <operation> [<dialog>]; default value: n/a) Bind key <key> to <operation>. This means that whenever <key> is pressed, then <operation> is executed (if applicable in the current dialog). A list of available operations can be found below. Optionally, you can specify a dialog. If you specify one, the key binding will only be added to the specified dialog. Available dialogs are "all" (default if none is specified), "feedlist", "filebrowser", "help", "articlelist", "article", "tagselection", "filterselection", "urlview" and "podbeuter". (example: bind-key ^R reload-all) bookmark-cmd (parameters: <bookmark-command>; default value: "") If set, then <bookmark-command> will be used as bookmarking plugin. See the documentation on bookmarking for further information. (example: bookmark-cmd "~/bin/delicious-bookmark.sh") bookmark-interactive (parameters: [yes/no]; default value: no) If set to yes, then the configured bookmark command is an interactive program. (example: bookmark-interactive yes) browser (parameters: <browser-command>; default value: lynx) Set the browser command to use when opening an article in the browser. If <browser-command> contains %u, it will be used as complete commandline and %u will be replaced with the URL that shall be opened. (example: browser "w3m %u") cache-file (parameters: <path>; default value: "~/.newsbeuter/cache.db") This configuration option sets the cache file. This is especially useful if the filesystem of your home directory doesn’t support proper locking (e.g. NFS). (example: cache-file "/tmp/testcache.db") cleanup-on-quit (parameters: [yes/no]; default value: yes) If yes, then the cache gets locked and superfluous feeds and items are removed, such as feeds that can’t be found in the urls configuration file anymore. (example: cleanup-on-quit no) color (parameters: <element> <fgcolor> <bgcolor> [<attr> ...]; default value: n/a) Set the foreground color, background color and optional attributes for a certain element (example: color background white black) confirm-exit (parameters: [yes/no]; default value: no) If set to yes, then newsbeuter will ask for confirmation whether the user really wants to quit newsbeuter. (example: confirm-exit yes) cookie-cache (parameters: <file>; default value: "") Set a cookie cache. If set, then cookies will be cached (i.e. read from and written to) in this file. (example: cookie-cache "~/.newsbeuter/cookies.txt") datetime-format (parameters: <date/time format>; default value: %b %d) This format specifies the date/time format in the article list. For a detailed documentation on the allowed formats, consult the manpage of strftime(3). (example: datetime-format "%D, %R") define-filter (parameters: <name> <filter>; default value: n/a) With this command, you can predefine filters, which can you later select from a list, and which are then applied after selection. This is especially useful for filters that you need often and you don’t want to enter them every time you need them. (example: define-filter "all feeds with fun tag" "tags # \\"fun\\"") display-article-progress (parameters: [yes/no]; default value: yes) If set to yes, then a read progress (in percent) is displayed in the article view. Otherwise, no read progress is displayed. (example: display-article-progress no) download-retries (parameters: <number retries>; default value: 1) How many times newsbeuter shall try to successfully download a feed before giving up. This is an option to improve the success of downloads on slow and shaky connections such as via a TOR proxy. (example: download-retries 4) download-full-page (parameters: [yes/no]; default value: no) If set to yes, then for all feed items with no content but with a link, the link is downloaded and the result used as content instead. This may significantly increase the download times of "empty" feeds. (example: download-full-page yes) download-timeout (parameters: <seconds>; default value: 30) The number of seconds newsbeuter shall wait when downloading a feed before giving up. This is an option to improve the success of downloads on slow and shaky connections such as via a TOR proxy. (example: download-timeout 60) error-log (parameters: <path>; default value: "") If set, then user errors (e.g. errors regarding defunct RSS feeds) will be logged to this file. (example: error-log "~/.newsbeuter/error.log") external-url-viewer (parameters: <command>; default value: "") If set, then "show-urls" will pipe the current article to a specific external tool instead of using the internal URL viewer. This can be used to integrate tools such as urlview. (example: external-url-viewer "urlview") feed-sort-order (parameters: <sortorder>; default value: none) If set to "firsttag", the feeds in the feed list will be sorted by their first tag in the urls file. (example: feed-sort-order firsttag) feedlist-format (parameters: <format>; default value: "%4i %n %11u %t") This variable defines the format of entries in the feed list. See the respective section in the documentation for more information on format strings. (example: feedlist-format " %n %4i - %11u -%> %t") googlereader-flag-share (parameters: <flag>; default value: "") If this is set and Google Reader support is used, then all articles that are flagged with the specified flag are being "shared" in Google Reader so that people that follow you can see it. (example: googlereader-flag-share "a") googlereader-flag-star (parameters: <flag>; default value: "") If this is set and Google Reader support is used, then all articles that are flagged with the specified flag are being "starred" in Google Reader and appear in the list of "Starred items". (example: googlereader-flag-star "b") googlereader-login (parameters: <login>; default value: "") This variable sets your Google Reader login for the Google Reader support. (example: googlereader-login "your-login") googlereader-min-items (parameters: <number>; default value: 20) This variable sets the number of articles that are loaded from Google Reader per feed. (example: googlereader-min-items 100) googlereader-password (parameters: <password>; default value: "") This variable sets your Google Reader password for the Google Reader support. (example: googlereader-password "your-password") googlereader-passwordfile (parameters: <path-to-file; default value: "") A more secure alternative to the above, by storing your password elsewhere in your system. (example: googlereader-passwordfile "path-to-file") googlereader-show-special-feeds (parameters: [yes/no]; default value: yes) If this is set, then "special feeds" like "People you follow" (articles shared by people you follow), "Starred items" (your starred articles), "Shared items" (your shared articles) and "Popular items" (articles considered to be popular by Google’s magic algorithms) appear in your subscription list. (example: googlereader-show-special-feeds "no") goto-first-unread (parameters: [yes/no]; default value: yes) If set to yes (the default), then the first unread article will be selected whenever a feed is entered. (example: goto-first-unread no) goto-next-feed (parameters: [yes/no]; default value: yes) If set to yes, then the next-unread and prev-unread keys will search in other feeds for unread articles if all articles in the current feed are read. If set to no, then the next-unread and prev-unread keys will stop in the current feed. (example: goto-next-feed no) highlight (parameters: <target> <regex> <fgcolor> [<bgcolor> [<attribute> ...]]; default value: n/a) With this command, you can highlight text parts in the feed list, the article list and the article view. For a detailed documentation, see the chapter on highlighting. (example: highlight all "newsbeuter" red) highlight-article (parameters: <filterexpr> <fgcolor> <bgcolor> [<attribute> ...]; default value: n/a) With this command, you can highlight articles in the article list if they match a filter expression. For a detailed documentation, see the chapter on highlighting. (example: highlight-article "author =~ \\"Andreas Krennmair\\"" white red bold) history-limit (parameters: <number>; default value: 100) Defines the maximum number of entries of commandline resp. search history to be saved. To disable history saving, set history-limit to 0. (example: history-limit 0) html-renderer (parameters: <path>; default value: internal) If set to "internal", then the internal HTML renderer will be used. Otherwise, the specified command will be executed, the HTML to be rendered will be written to the command’s stdin, and the program’s output will be displayed. This makes it possible to use other, external programs, such as w3m, links or lynx, to render HTML. (example: html-renderer "w3m -dump -T text/html") http-auth-method (parameters: <method>; default value: any) Set HTTP authentication method. Allowed values: any, basic, digest, digest_ie (only available with libcurl 7.19.3 and newer), gssnegotiate, ntlm, anysafe. (example: http-auth-method digest) ignore-article (parameters: <feed> <filterexpr>; default value: n/a) If a downloaded article from <feed> matches <filterexpr>, then it is ignored and not presented to the user. This command is further explained in the "kill file" section below. (example: ignore-article "*" "title =~ \\"Windows\\"") ignore-mode (parameters: [download/display]; default value: download) This configuration option defines in what way an article is ignored (see ignore-article). If set to "download", then it is ignored in the download/parsing phase (which is the default) and thus never written to the cache, if it set to "display", it is ignored when displaying articles but is kept in the cache. (example: ignore-mode "display") include (parameters: <path>; default value: n/a) With this command, you can include other files to be interpreted as configuration files. This is especially useful to separate your configuration into several files, e.g. key configuration, color configuration, ... (example: include "~/.newsbeuter/colors") keep-articles-days (parameters: <days>; default value: 0) If set the a number greater than 0, only articles that are were published within the last <n> days are kept, and older articles are deleted.

(example: keep-articles-days 30) macro (parameters: <macro key> <command list>; default value: n/a) With this command, you can define a macro key and specify a list of commands that shall be executed when the macro prefix and the macro key are pressed. (example: macro k open ; reload ; quit) mark-as-read-on-hover (parameters: [yes/no]; default value: no) If set to yes, then all articles that get selected in the article list are marked as read. (example: mark-as-read-on-hover yes) max-download-speed (parameters: <number>; default value: 0) If set to a number great than 0, the download speed per download is set to that limit (in kB). (example: max-download-speed 50) max-items (parameters: <number>; default value: 0) Set the number of articles to maximally keep per feed. If the number is set to 0, then all articles are kept. (example: max-items 100) notify-format (parameters: <string>; default value: "newsbeuter: finished reload, %f unread feeds (%n unread articles total)") Format string that is used for formatting notifications. See the chapter on format strings for more information. (example: notify-format "%d new articles (%n unread articles, %f unread feeds)") notify-program (parameters: <path>; default value: "") If set, then the configured program will be executed if new articles arrived (through a reload) or if notify-always is true. The first parameter of the called program contains the notification message. (example: notify-program "~/bin/my-notifier") notify-always (parameters: [yes/no]; default value: no) If no, notifications will only be made when there are new feeds or articles. If yes, notifications will be made regardless. (example: notify-always yes) notify-screen (parameters: [yes/no]; default value: no) If yes, then a "privacy message" will be sent to the terminal, containing a notification message about new articles. This is especially useful if you use terminal emulations such as GNU screen which implement privacy messages. (example: notify-screen yes) notify-xterm (parameters: [yes/no]; default value: no) If yes, then the xterm window title will be set to a notification message about new articles. (example: notify-xterm yes) notify-beep (parameters: [yes/no]; default value: no) If yes, then the speaker beep on new articles. (example: notify-beep yes) opml-url (parameters: <url> ...; default value: "") If the OPML online subscription mode is enabled, then the list of feeds will be taken from the OPML file found on this location. Optionally, you can specify more than one URL. All the listed OPML URLs will then be taken into account when loading the feed list. (example: opml-url "http://host.domain.tld/blogroll.opml" "http://example.com/anotheropmlfile.opml") pager (parameters: [<path>/internal]; default value: internal) If set to "internal", then the internal pager will be used. Otherwise, the article to be displayed will be rendered to be a temporary file and then displayed with the configured pager. If the pager path is set to an empty string, the content of the "PAGER" environment variable will be used. If the pager path contains a placeholder "%f", it will be replaced with the temporary filename. (example: less %f) podcast-auto-enqueue (parameters: [yes/no]; default value: no) If yes, then all podcast URLs that are found in articles are added to the podcast download queue. See the respective section in the documentation for more information on podcast support in newsbeuter.

This is equivalent to the -r commandline option. (example: refresh-on-startup yes) reload-only-visible-feeds (parameters: [yes/no]; default value: no) If yes, then manually reloading all feeds will only reload the currently visible feeds, e.g. if a filter or a tag is set. (example: reload-only-visible-feeds yes) reload-time (parameters: <number>; default value: 60) The number of minutes between automatic reloads. (example: reload-time 120) reload-threads (parameters: <number>; default value: 1) The number of parallel reload threads that shall be started when all feeds are reloaded. (example: reload-threads 3) reset-unread-on-update (parameters: <url> ...; default value: n/a) With this configuration command, you can provide a list of RSS feed URLs for whose articles the unread flag will be reset if an article has been updated, i.e. its content has been changed. This is especially useful for RSS feeds where single articles are updated after publication, and you want to be notified of the updates. (example: reset-unread-on-update "http://blog.fefe.de/rss.xml?html") save-path (parameters: <path>; default value: ~/) The default path where articles shall be saved to. If an invalid path is specified, the current directory is used. (example: save-path "~/Saved Articles") search-highlight-colors (parameters: <fgcolor> <bgcolor> [<attribute> ...]; default value: black yellow bold) This configuration command specifies the highlighting colors when searching for text from the article view. (example: search-highlight-colors white black bold) show-keymap-hint (parameters: [yes/no]; default value: yes) If no, then the keymap hints on the bottom of screen will not be displayed. (example: show-keymap-hint no) show-read-feeds (parameters: [yes/no]; default value: yes) If yes, then all feeds, including those without unread articles, are listed. If no, then only feeds with one or more unread articles are list. (example: show-read-feeds no) show-read-articles (parameters: [yes/no]; default value: yes) If yes, then all articles of a feed are listed in the article list. If no, then only unread articles are listed. (example: show-read-articles no) suppress-first-reload (parameters: [yes/no]; default value: no) If yes, then the first automatic reload will be suppressed if auto-reload is set to yes. (example: suppress-first-reload yes) text-width (parameters: <number>; default value: 0) If set to a number greater than 0, then all HTML will be rendered to this maximum line length. If set to 0, the terminal width will be used. (example: text-width 72) ttrss-flag-publish (parameters: <character>; default value: "") If this is set and Tiny Tiny RSS support is used, then all articles that are flagged with the specified flag are being marked as "published" in Tiny Tiny RSS. (example: ttrss-flag-publish "b") ttrss-flag-star (parameters: <character>; default value: "") If this is set and Tiny Tiny RSS support is used, then all articles that are flagged with the specified flag are being "starred" in Tiny Tiny RSS. (example: ttrss-flag-star "a") ttrss-login (parameters: <username>; default value: "") Sets the username for use with Tiny Tiny RSS. (example: ttrss-login "admin") ttrss-mode (parameters: [multi/single]; default value: multi) Configures the mode in which Tiny Tiny RSS is used. In single-user mode, login and password are used for HTTP authentication, while in multi-user mode, they are used for authenticating with Tiny Tiny RSS.

(example: ttrss-url "http://example.com/ttrss/") unbind-key (parameters: <key> [<dialog>]; default value: n/a) Unbind key <key>. This means that no operation is called when <key> is pressed. Optionally, you can specify a dialog (for a list of available dialogs, see "bind-key" above). If you specify one, the key binding will only be unbound for the specified dialog. (example: unbind-key R) urls-source (parameters: <source>; default value: "local") This configuration command sets the source where URLs shall be retrieved from. By default, this is ~/.newsbeuter/urls. Alternatively, you can set it to "opml", which enables newsbeuter’s OPML online subscription mode, to "ttrss" which enables newsbeuter’s Tiny Tiny RSS support, or to "googlereader", which enables newsbeuter’s Google Reader support. In order to make Google Reader support work correctly, you also need to set googlereader-login and googlereader-password, while the Tiny Tiny RSS support requires login, password and URL of the Tiny Tiny RSS installation to use (see above). (example: urls-source "googlereader") use-proxy (parameters: [yes/no]; default value: no) If yes, then the configured proxy will be used for downloading the RSS feeds. (example: use-proxy yes) user-agent (parameters: <user agent string>; default value: "") If set to a non-zero-length string, this value will be used as HTTP User-Agent header for all HTTP requests.

TAGGING Newsbeuter comes with the possibility to categorize or "tag", as we call it, RSS feeds. Every RSS feed can be assigned 0 or more tags. Within newsbeuter, you can then select to only show RSS feeds that match a certain tag. That makes it easy to categorize your feeds in a flexible and powerful way. Usually, the ~/.newsbeuter/urls file contains one RSS feed URL per line. To assign a tag to an RSS feed, simply attach it as a single word, separated by blanks such as space or tab. If the tag needs to contain spaces, you must use quotes (") around the tag (see example below). An example \~/.newsbeuter/urls file may look like this: http://blog.fefe.de/rss.xml?html interesting conspiracy news "cool stuff" http://rss.orf.at/news.xml news orf http://www.heise.de/newsticker/heise.rdf news interesting When you now start newsbeuter with this configuration, you can press "t" to select a tag. When you select the tag "news", you will see all three RSS feeds. Pressing "t" again and e.g. selecting the "conspiracy" tag, you will only see the http://blog.fefe.de/rss.xml?html RSS feed. Pressing "^T" clears the current tag, and again shows all RSS feeds, regardless of their assigned tags. A special type of tag are tags that start with the tilde character ("~"). When such a tag is found, the feed title is set to the tag name (excluding the \~ character). With this feature, you can give feeds any title you want in your feed list: http://rss.orf.at/news.xml "~ORF News" SCRIPTS AND FILTERS From version 0.4 on, newsbeuter contains support for Snownews extensions. The RSS feed readers Snownews and Liferea share a common way of extending the readers with custom scripts. Two mechanisms, namely "execurl" and "filter" type scripts, are available and supported by newsbeuter. An "execurl" script can be any program that gets executed and whose output is interpreted as RSS feed, while "filter" scripts are fed with the content of a configured URL and whose output is interpreted as RSS feed. The configuration is simple and straight-forward. Just add to your ~/.newsbeuter/urls file configuration lines like the following ones: exec:~/bin/execurl-script filter:~/bin/filter-script:http://some.test/url The first line shows how to add an execurl script to your configuration: start the line with "exec:" and then immediately append the path of the script that shall be executed. If this script requires additional parameters, simply use quotes: "exec:~/bin/execurl-script param1 param2" The second line shows how to add a filter script to your configuration: start the line with "filter:", then immediately append the path of the script, then append a colon (":"), and then append the URL of the file that shall be fed to the script. Again, if the script requires any parameters, simply quote: "filter:~/bin/filter-script param1 param2:http://url/foobar" In both cases, the tagging feature as described above is still available: exec:~/bin/execurl-script tag1 tag2 "quoted tag" filter:~/bin/filter-script:http://some.test/url tag3 tag4 tag5 A collection of such extension scripts can be found on this website: http://kiza.kcore.de/software/snownews/snowscripts/extensions If you want to write your own extensions, refer to this website for further instructions: http://kiza.kcore.de/software/snownews/snowscripts/writing COMMAND LINE Like other text-oriented software, newsbeuter contains an internal commandline to modify configuration variables ad hoc and to run own commands. It provides a flexible access to the functionality of newsbeuter which is especially useful for advanced users. To start the commandline, type ":". You will see a ":" prompt at the bottom of the screen, similar to tools like vi(m) or mutt. You can now enter commands. Pressing the return key executes the command (possibly giving feedback to the user) and closes the commandline. You can cancel entering commands by pressing the ESC key. The history of all the commands that you enter will be saved to \~/.newsbeuter/history.cmdline. The backlog is limited to 100 entries by default, but can be influenced by setting the "history-limit" configuration variable. To disable history saving, set the history-limit to 0. Starting with newsbeuter 2.0, the commandline provides you with some help if you can’t remember the full names of commandline commands. By pressing the TAB key, newsbeuter will try to automatically complete your command. If there is more than one possible completion, you can subsequently press the TAB key to cycle through all results. If no match is found, no suggestion will be inserted into the commandline. For the "set" command, the completion also works for configuration variable names. In additon, some common key combination such as Ctrl-G (to cancel input), Ctrl-K (to delete text from the cursor position to the end of line), Ctrl-U (to clear the whole line) and Ctrl-W (to delete the word before the current cursor position) were added. Please be aware that the input history of both the command line and the search functions are saved to the filesystems, to the files ~/.newsbeuter/history.cmdline resp. \~/.newsbeuter/history.search. By default, the last 100 entries are saved, but this can be configured (configuratin variable history-limit) and also totally disabled (by setting said variable to 0). Currently, the following command line commands are available: quit Quit newsbeuter save <filename> Save current article to <filename> set <variable>[=<value>|&|!] Set (or get) configuration variable value. Specifying a ! after the name of a boolean configuration variable toggles their values, a & directly after the name of a configuration variable of any type resets its value to the documented default value. tag <tagname> Select a certain tag goto <case-insensitive substring> Go to the next feed whose name contains the case-insensitive substring. source <filename> [...] Load the specified configuration files. This allows it to load alternative configuration files or reload already loaded configuration files on-the-fly from the filesystem. dumpconfig <filename> Save current internal state of configuration to file, so that it can be instantly reused as configuration file. <number> Jump to the <number>th entry in the current dialog FILES $HOME/.newsbeuter/config $HOME/.newsbeuter/urls SEE ALSO podbeuter(1). The documentation that comes with newsbeuter is a good source about the general use and configuration of newsbeuter.

We seamlessly transition between developing for the Browser and Node.js (and sometimes both!)
We can take advantage of the great extensions and frameworks around Backbone.js
We can mix-and-match databases to choose the best tool for the job
We focus on solving problems not memorizing APIs that may differ client/server
I wrote intial mongodb version and thought I was half way. More like a quarter
There were many long days and late nights filled with epiphanies: "So that's why A/B/C did X/Y/Z"
Things like: What do we do when adding related items are not loaded?
How far do we go to ensure database integrity? (it depends, both is the answer)

MIT Sloan Management Review and Deloitte’s 2015 global study of digital business found that maturing digital businesses are focused on integrating digital technologies, such as social, mobile, analytics and cloud, in the service of transforming how their businesses work. Less-mature digital businesses are focused on solving discrete business problems with individual digital technologies.

Introduction
Before we start
I looked up from the screen of my iPad to my father, lying unconscious, amid tubes and wires, in his starship of a bed, in the irresolute darkness of an I.C.U. at 3 a.m. Ordinarily when my father lay on his back his abdomen rose up like the telescope dome of an observatory, but now there seemed to be nothing between the bed rails at all, just a blanket pulled as taut as a drum skin and then, on the pillow, my father’s big, silver-maned head. Scarecrow, after the flying monkeys had finished with him.  All the darkness in the room seemed to pool in his open mouth. Hey, Dad, I need a line, I said, breaking, if only in my head, the silence that reigned between us. I’m writing dialogue for Mr. Spock.
 There was never any trace of a response. No twitch of an eye or a cheek, no ghost of a tender or rueful smile. I wanted to believe that he’d heard me, heard that I loved him, that I forgave him, that I was thankful to him for having taught me to love so many of the things I loved most, “Star Trek” among them, but it felt like throwing a wish and a penny into a dry fountain. My father and I had already done all the talking we were ever going to do. Can’t help you there, said my father, a pediatrician, though long retired from practice. Now, if you were writing dialogue for Doctor Spock . . . My father had slipped into unconsciousness twelve hours earlier, about an hour after we stopped the intravenous adrenaline that had been keeping his blood pressure up. Until then, he’d been responsive, aware, irritable, funny, querulous, weak, confused, furious, loopy, but recognizably himself. A studied, even militant avoider of exercise all his life, he had been seriously overweight for most of the past forty years, diabetic for a decade. His kidneys were failing. So was his liver. The latest enemy was acute hypotension, which when untreated would drop him into the scary nether regions of the mmHg scale. But the norepinephrine drip that could magically restore my father to a close approximation of the man we remembered was likely to put him into cardiac arrest. His caregivers had gently and regretfully begun to suggest that it might be time to stop treating this particular element among the complex of things that were killing him. A heart attack would be painful and frightening.

Slate roofing tile has a long and storied history, and is generally known as one of the highest quality, longest lasting roofing materials on the market. But there are many things homeowners should be aware of before choosing slate roofing tile. Homeowners are drawn to slate tile mainly because of its beauty and longevity. Slate tile can come in varying thicknesses and natural mixed colors. When properly installed, slate tile is buit to last at least a century. On the other hand, slate tile can be very costly and it can be very hard to replace damaged tile. Homeowners also need to have their residences evaluated before installing slate tile to make sure their homes can support the weight.

Arrays and Hashes
1.3.2016Ruby uses Arrays and Hashes to store collections of objects. Objects include strings, integers, arrays, hashes, nil, true, false, etc. While they both fundamentally do the same thing, they do so in different ways. Before we get into their differences let's look at some more similarities.
As noted above, they both store a collection of objects. Additionally, arrays and hashes both share a lot of similar notation. To create a new array you could use either:
Array.newAnd as you can imagine Hashes can be created like so:
array = []
Hash.newYou may have noticed that arrays use square brackets
hash = {}
[]
while
hashes use curly brackets {}
Now that the Array and Hash exist, we can add data to them.
array[0] = 72Here is where we start to get to their differences. Both store data which can be accessed through an index. Arrays use an integer index. In the example above we are setting the 0-th spot of the array to 72. Hashes use a key/value pair. The key can be anything as long as it is unique and it will be assigned to a specific value. Arrays also remember the order in which objects were entered into them. Hashes now also remember the order of insertion (thanks to Ruby 1.9!) though they previous did not.
hash = ["key"] = "value"
The two seem pretty similar, so when do you use which? If your data needs a specific label, a hash is the best answer. This way you can customize the keys to all of the data. Otherwise you could use an array. If order is important you can use an array. Yes, hashes now too keep order in mind but it seems that arrays are usually used to store ordered information. Lastly, arrays are good for queue or stack structure.
