So it has the potential to be very widely usable. You don't have to install a program on the users computer so you can skip operating system issues and you don't need a IT administrator to be involved if the users are in a school or university where installing programmes is restricted. Installing something on a users computer before the can take part in a chat is at best an inconvenience and a source of friction. Your saved the work of supporting multiple operating systems and developers who build the programmes. Its also the future so more and more devices and browsers should support it.

Weaknesses

Fundamentally your restricted to the browser so integrating with the users computer outside of the browser box for something like screen sharing or sharing access to an application is cut off. You can create extensions or plugins to enable screen sharing. The user also has to allow their browser to share the video and sound from their system. You prompt them and they click to allow all or in some browsers just a single part sound or video. This shows another potential downside your restricted by browsers some what, you don't have to have the latest shiniest but you need something reasonably up to date. Google Chrome, Firefox work ok, and I think Edge. Unfortunately as you may have noticed those don't include Safari which restricts iPhone and iPad access. I've not found a why to this it just seems to be something Apple don't want to enable, yet. Some plugins exist that claim to enable WebRTC in the deficient browsers. whilst this seems negative I think more widespread support will emerge in the future. There is a browser support page here http://iswebrtcreadyyet.com/.
Mostly communication is peer to peer with some negotiation STUN (Session Traversal Utilities for NAT) server if that doesn't work because of network topology then your forced to use a TURN server. This is not so shiny as it means you using the TURN server to relay message between chat members, this is a potential source of delays and processing demand on the TURN server your running. In my testing though I was able to use just the STUN server, I guess the TURN server would be more likely to need to used when one of the chat members was inside a large organisation. Its worth while considering the peer to per nature of the communication if you want to record chats as the data may not go through a central point where you can push it to a file. Handling between browsers varies slightly so you may want to use a framework that abstracts that away somewhat I used Simple WebRTC (https://simplewebrtc.com/). there are also services that offer WebRTC or parts as a service that you can than integrate into a wider application, if you want to find out more about to about the JavaScript its worth looking at the work of Muaz Khan at https://www.webrtc-experiment.com/. Ultimately I build a demo system in order to demonstrate feasibility and then stopped as there wasn't the budget at that point. Perhaps at some point that project will happen but its always useful to know what is and isn't feasible and what the limits of a technology are to use in others. ]]>

Signed by: coldfusionisalive.com The signed by bit indicates that the email is signed by the coldfusionisalive.com server so you can be somewhat reassured that the email does come from the right server rather than a spammer. Found that most of my email addresses have DKIM set up without me doing anything which is nice. If you find yourself setting up DKIM or want to check its not setup wrong on your mail server you can also send a test email using that account to check-auth@verifier.port25.com and they very nicely send you something back with a summary like this ========================================================== Summary of Results ========================================================== SPF check: pass DomainKeys check: pass DKIM check: fail SpamAssassin check: ham and lots of details which was very useful. I was setting it up on a old server where it wasn't just a tick box and it took me many attempts before I got it all to hang to together and the signing to validate successfully. (Canonicalization was what the last thing I was tripping up over in my opendkim.conf) DMARC Once you have SPF and DKIM setup you can then go on to set DMARC which gives you some reporting on whatis happening when your emails reach bigger mail hosts like googlemail and outlook. It also provides a way of you instructing the receiving mail server to what to do if the mail sent to them fails to pass DKIM or SPF checks. There is quite a lot to a DMARC record the best explanation I found was this one https://support.google.com/a/answer/2466563?hl=en. I ended up with something like this: _dmarc.example.com TXT v=DMARC1; p=none; rua=mailto:dmarc@example.com so I'm not telling receiving servers to do anything other than report to an email address. After a while and as my understanding increases I'll probably instruct it to do more possibly breaking actions (quarantine, reject) None of this really improves the security of email its still at some point being sent in plain text but it does give a receiving mail server another method of verifying that the email its received is legitimately from who it says it is. So in the end is making it more difficult for someone to send emails pretending to be from you. ]]> <![CDATA[Converting flv files to mp3 on CLI]]> http://geeklog.adamwilson.info/article/83/Converting-flv-files-to-mp3-on-CLI http://geeklog.adamwilson.info/article/83/Converting-flv-files-to-mp3-on-CLI Mon, 15 Aug 2016 15:27:07 BST #!/bin/bash # extract audio from flv files to mp3 files # using vlc app for file in /Directory/*.flv; do /Applications/VLC.app/Contents/MacOS/VLC -I dummy $file --sout="#transcode{vcodec=dummy,acodec=mp3,ab=128,channels=2,samplerate=44100,scodec=none}:standard{mux=raw,access=file{overwrite},dst=\"$(echo "$file" | sed 's/\.[^\.]*$/.mp3/')\"}" vlc://quit; done; You end up with the Directory full of the original then converted version. aardvark.flv aardvark.mp3 cartilage.flv cartilage.mp3 This post was very helpful in working out the basis.

Tests: 248, Assertions: 5606, Skipped: 4. Now trying humbug it may take some time ... Humbug on the above set of tests took 1.43 hours and there was a lot of output that made understanding it difficult. The output was quite useful though in that it showed weaknesses in my tests the --incremental flag is designed to speed up the test somewhat although in my circumstances it didn't make a large difference. To be honest at least at first you probably want to try this out on something smaller with just a few tests at first the output is easier to understand when your doing it on a smaller set of tests. You get an output file with diffs so you can have a look through and see how Humbug has twisted your code about. The one produced for the unit tests above was about 6000 lines. Then your left viewing the issues do they matter or are they false warnings. 1) \Humbug\Mutator\ReturnValue\This Diff on \adminLessonAccess::__construct() in /classes/adminLessonAccess.php: --- Original +++ New @@ @@ $this->db =3D dbConnection::get(); - return $this; + return null; } function listLessonsForAdminAccess(){ So my tests did not cover the constructor returning null rather than $this. 2) \Humbug\Mutator\Boolean\TrueValue Diff on \adminLessonAccess::deleteAllExpiredIds() in /classes/adminLessonAccess.php: --- Original +++ New @@ @@ } - return True; + return false; } Looking at the tests, my test covered that the things were deleted but not that the result should be true. Which isn't the end of the world but its a simple line to add an assertion that that should turn True; I think its a really useful tool in blowing a hole through how solid you thought your unit tests were according to code coverage stats and also in helping you improve existing unit tests and create better new ones.

Version

I was using Humbug version 1.0.0-alpha1-18-gd102496 as a phar my humbug.dist.json looks like this { "source": { "directories": [ "../classes" ], "excludes": [ "../classes/PHPExcel" ] }, "timeout": 10, "logs": { "text": "humbuglog.txt" } }

Why do mutation testing at all

Pádraic probably answers that a lot better than I can in his article (currently down) if that link doesn't work try this. Put simply code coverage stats can be pretty overrated. They are good at showing how much of your code has tests but don't answer the other questions.
  • How good are those tests,
  • do they really test the code properly
  • are they just thin coverage filler written to achieve a coverage statistic.
  • are the tests strict or fluffy
  • are the tests redundant
These are some of the things you can get a better idea of with mutation testing. ]]>

First ran least stringent which didn't produce much (possibly my code base is a magical unicorn) ./phan -p --minimum-severity=10 --quick --ignore-undeclared -f files.txt -o out.txt So then went to severest which produced noise ./phan -p --minimum-severity=0 --backward-compatibility-checks --dead-code-detection -f files.txt -o out.txt So then dialed back to ./phan --progress-bar --minimum-severity=0 --backward-compatibility-checks --file-list files.txt --ignore-undeclared --output out.txt There are possibly false warnings but it does give you an idea of places that might need consideration. Here I'm operating on a the result of a function that might return False on no results or an array of results on success. $siblings = $this->getSiblingsForAssessment($siblingGroups,$problemSetId); if($siblings){ $siblings = implode(',', $siblings); }else{ Which causes it to fuss as its thinking that $siblings is a (bool) ie True/False when it gets to $siblings = implode(',', $siblings); /classes/assessment.php:210 PhanParamSpecial1 Argument 2 (pieces) is bool but \implode() takes array when argument 1 is string /classes/assessment.php:210 PhanTypeMismatchArgumentInternal Argument 2 (glue) is bool but \implode() takes string Perhaps in a more functional world we wouldn't want to do something where the type of a value changes but in a php world where variables are mutable and type is flexible perhaps its not so bad. it can produce you more straight forwardly useful things like /classes/bookingChange.php:311 PhanNoopVariable Unused variable which was a pointless line $lessonStartDateTime; and warning you about optional arguments that are followed by non optional arguments in function calls PhanParamTooMany Call with 6 arg(s) to \className::functionName() which only takes 5 arg(s) so thats probably not intentional. Its probably useful as a way of reviewing code occasionally for smells and possible issues. I wouldn't worry about running as often as unit tests. Perhaps it would be useful as a way of viewing other peoples code or new code. Seems like its aimed athelping move a code base forward and stop it slipping back into old ‘bad’ habits.

It is aimed at verifying that when a site is calling resources from a remote resource such as a CDN that the resources returned match that expected and the content have not been modified by some outside agent. For example the page example.com/index.html loads css from cdn.example.com/layout.css but has no idea if cdn.example.com/layout.css is what it expects or has been modified by some malicious agent so all the text is pink. (possibly by militant my little pony fan girls) SRI allows example.com/index.html link tag to include a hash of what the called resource should be <link rel="stylesheet" href="//cdn.example.com/layout.css" integrity="HASH M6kredJcxdsqkczBUjMLvqyHb1KHASH"> With HASHM6kredJcxdsqkczBUjMLvqyHb1KHASH being a hash of layout.css. This integrity attribute can be used by the user agent in this case a browser to avoid executing malicious or substituted code. If you think that the remote resource could be a script and you really don't want some random javascript injected in your page.

There may be fairly simple errors, for example: I upgraded the shop to the latest greatest in the 1.9 line thinking that those issues would be resolved they weren't. Mine were kind of minor, if your bought something with paypal buy now button the name of the customer would be blank on the 5 most recent orders. If you looked at the status of the order it would spray out html code rather than the link to the verify id. These aren't that bad and you can fix, reasonably easily. More to say that don't think everything will work just because its so widely used.
2) You need a beefy machine, this isn't going to work to well on shared hosting and its worth checking out how far you can push the PHP version beyond what versions they officially support. Newer versions of PHP being faster, generally. I pushed to .1 down from latest greatest version with some tweaking of the invoice creation code. Not got it onto php 7 (yet) though. The database is going to be a big and get bigger still so check your MySQL setup.
3) Its never going to be very fast, it wasn't really built to PHPs strengths. You are going to be working on coping with the core design decisions they made. Your back end options include enabling caching on as much as possible, including additional caching levels, I added a full page caching plugin Lesti which seems to work ok and reduced the time taken to actually chuckout the html to under 100ms. You will have to checkout that you have excluded the blocks that are customer specific. Magento have written some whitepapers about performance which are perhaps worth whizzing through. Including some configs that might work as starting points in Varnish, Nginx, PHP-FPM
4) Caching is also the root of problems if things don't appear or don't change on your updates after you 'update cache' in admin. Try emptying the cache directory rm -rf var/cache/
5) Front end performance may not be that fantastic either, check if combining the many and various css and js files speed things up for you and things still work.
6) If you amend a css file, the file name of the combined css will not change to do that you have to change the names of the files or do something like add a blank css file named cssBuster-{monthName}-{dayName}.css and add that to the layout.xml that you upload simultaneously.
7) You can update on the command line checkout ./mage list-upgrades
8) You can do reindexing from the command line php shell/indexer.php help I found reindexing periodically whether it needed it or not worthwhile. Having it update on save or manually is dependent on your evaluation and how understanding the shop keeper is of messages that may get flashed up whilst the are waiting for update. If your indexing is slow out check this plugin out. Depending on your config it skips, non visible and hidden url indexing which can greatly improves the speed, in my case it went from 50 seconds to 8 seconds
9) Log cleaning on the command line, log cleaning does keep the database size down I went from a database archive of something around 600mb to 260mb initially as no one had done it previously.
10) You probably want to enable as much logging as you can System > Developer > Log Settings The logs are quite noisy by default but you can grep out the noise and show the exceptional stuff. I have a rough bash script to process the system log for example.
11) Repeated blocked calls to /app/etc/config.xml in your logs are actually calls from Magento itself checking that that file is hidden, not an attacker. Although people do attack so you want to check your configuration, specifically to Magento files like LICENSE.* and *.sample probably don't need to be there. You also need to consider if you want to have the downloader online.
12) Checkout get.php it may be set to display errors, you don't want it to. It may be worth putting a die() in if you don't want to use it/ disagree with the concept of get.php.
13) If you can't login to the admin on a test server checkout the cookie domain see if it looks right. You can do something like this to make it blank in sql UPDATE prefix_core_config_data set value = '' where path = 'web/cookie/cookie_domain';
14) You can serve your static files from a CDN (and then toggle that according to if you are on https or not).
15) You set the timezone here System > Configuration > General > Locale Options > Timezone but Magento doesn't do British Summer time so you get times in GMT which may confuse you. It seems you can fiddle with it.
I'm still not sure I would recommend Magento to anyone, but I guess it works. ]]>

Then it worked dandy.
Mines a 2007 imac so it may be an older mac issue and different for you. I had changed router at some point and I think after that it failed, which makes it seem obvious that was the issue but because I only used it seldomly and often offline I hadn't noticed.
I had discounted the router being the issue as the connection worked for so many seconds before it died. I looked at error logs (useless), load - nothing and pulled other stuff apart. Seems dumb now but with no error it was guess work. Resetting Pram, updating operating systems, viruses, screen rewrite frequency and repair disk were "solutions" I came across whilst googleing
So if you have something like that happen to you try disabling ipv6 and see if that helps first, before you try more complicated solutions and get more frustrated. ]]>

(This does not occur for other types such as |DATETIME|.) ... ... If you store a |TIMESTAMP| value, and then change the time zone and retrieve the value, the retrieved value is different from the value you stored." That last bit is very important should be in very big letters probably. So for example on my desktop if I store the current time with the computer set to the Australia Sydney Timezone and then set the time zone on the computer back to GMT I get a time out of the TIMESTAMP column that doesn't match what I put in. This is either really great because the values adjusted to the current time zone auto magically or really bad because your not getting back what your put in to your database. DATETIME keeps the same time regardless of the servers change in time zone. As a demonstration if I create this table CREATE TABLE `test` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `ts` timestamp NULL DEFAULT NULL, `dt` datetime DEFAULT NULL, `desc` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; and enter 2013-03-03 03:03:03 In both the 'ts' and 'dt' of the columns whilst my computer is set to 'Australian Eastern Daylight Time'. When I reset my time zone to 'GMT' I get this back ts = 2013-03-02 16:03:03 dt = 2013-03-03 03:03:03 This most probably would never be an issue unless your MySQL server changes its time zone unnoticed (perhaps after a restart) at some point and then you might be glad you had chosen DATETIME. ]]> <![CDATA[Using Selenium to simulate random users]]> http://geeklog.adamwilson.info/article/62/Using-Selenium-to-simulate-random-users http://geeklog.adamwilson.info/article/62/Using-Selenium-to-simulate-random-users Thu, 07 Feb 2013 11:13:33 GMT <![CDATA[Add Wolfram Alpha as a search engine in Firefox]]> http://geeklog.adamwilson.info/article/61/Add-Wolfram-Alpha-as-a-search-engine-in-Firefox http://geeklog.adamwilson.info/article/61/Add-Wolfram-Alpha-as-a-search-engine-in-Firefox Fri, 14 Dec 2012 15:48:19 GMT github here as wolframalpha.xml and save it in (on a mac) to /Applications/Firefox.app/Contents/MacOS/searchplugins/wolframalpha.xml Not sure quite where that file location is on Windows/Linux but guess its a similar path within the program. <SearchPlugin xmlns="http://www.mozilla.org/2006/browser/search/"> <ShortName>Wolfram Alpha</ShortName> <Description>Wolfram Alpha Search</Description> <InputEncoding>UTF-8</InputEncoding> <Image width="16" height="16">http://www.wolframalpha.com/favicon_calculate.png</Image> <Url type="application/x-suggestions+json" method="GET" template="http://www.wolframalpha.com/input/autocomplete.jsp?qr=0&i={searchTerms}" /> <Url type="text/html" method="GET" template="https://www.wolframalpha.com/input/?i={searchTerms}"> <Param name="i" value="{searchTerms}"/> </Url> <SearchForm>https://www.wolframalpha.com</SearchForm> </SearchPlugin> ]]> <![CDATA[Oddity with Javascript name in WordPress]]> http://geeklog.adamwilson.info/article/60/Oddity-with-Javascript-name-in-WordPress http://geeklog.adamwilson.info/article/60/Oddity-with-Javascript-name-in-WordPress Fri, 14 Dec 2012 15:33:56 GMT script src="/js/jquery-1.7.1.js" type="text/javascript" But all that happened was I got the wordpress 404 page instead I thought hmm quite a lot to myself then drank some more tea and tried script src="/js/jquery171.js" type="text/javascript Which works I think its the dots and dashes in the filename which makes the difference.

The site generally doesn't seem that much faster but it was pretty fast to start with. Sue it will affect other sites more dramatically. To be honest this is really excessive for this site, its really simple and I don't pay for bandwidth anyway but it seems better to try stuff out on your own site rather than on a clients. Its free though so no bother to try out and if your on dreamhost you don't even have to mess with dns, only tick a box and let them do it. Some cloudflare oddities : if you add a subdomain they say they have added the root domain so you do add geeklog.adamwilson.info, they say thankyou for adding adamwilson.info. Ignore this. Also they see themselves as a security layer for your site. I wasn't particularly interested in that, there aren't comments on this site and its not really something i'm worried about hackers on. By default they block certain ip's with a captcha challenge. That seemed a bit unfriendly to me so I turned it off you can tweak this how you want. You can turn it for your admin area or some other bit. They also do email obfuscation If your not already doing that. There are a lot of different features including analytics. Its quite neat. ]]> <![CDATA[Easing equations]]> http://geeklog.adamwilson.info/article/55/Easing-equations http://geeklog.adamwilson.info/article/55/Easing-equations Mon, 09 Apr 2012 19:00:15 BST this site lists a whole bunch in actionscript code snippets so you can see what kind of thing your aiming at and get a preview of the what each term means.
