Have you previously realised that www is redundant? If so, I’m preaching to the converted and you can run along back to whatever you were busy with. 😉 Otherwise, stand to attention, soldier!

begin rantish text:

When I’m browsing the web, I’d much less prefer to typewww.xkcd.comthanxkcd.com”. Reason being that if *every* site has to have w’s, what’s the point of the w’s? Not to mention that they’re a bitch to pronounce. There’s 9 syllables in there! You could almost halve that by sayingtriple-w”. I’ve heard people saydub dub dub”. Bleh. Even the World Wide Web Consortium prefers to call themselvesW3C”.

So what exactly is (was?) the point of the www? There might be more to it, however the gist of it appears to be that when Tim Berners-Lee first created the hypertext document retrieval system, he called itWorld Wide Web”. I believe that www became a standard not because it made sense or because it was a good idea, but because it was hyped far beyond the healthy respect it deserved.

Your web browser *knows* you’re dealing with web content solely by the fact that there’s an http:// in front of the url. Therefore I submit, the www is redundant.

Need more convincing?

Search engines see www.dogma.swiftspirit.co.za and dogma.swiftspirit.co.za as 2 separate web sites. Because both sites have identical content, search engines might lower your Search Rankings. Hell, you’d be competing against yourself for rankings. Silly example: instead of 3rd, you might be 5th і 7th. For this reason, it is better to either force www or to force no www. I’m in favour of the latter.

If you browse to http://www.dogma.swiftspirit.co.za/ you will be redirected to http://dogma.swiftspirit.co.za/. Even if you go to the downloads directory of my main domain with a www, you’ll be redirected appropriately. Importantly, search engines will only find one copy of my web site, НЕ 2. And in the long run, I’ll be wearing out my w key a li’l less. 🙂

With the possible exception of a few quick deaths, no w’s were hurt during the production of this post.

The relatively new document types Office 2007 has given some web hosts problems when their clients want to offer documents for download. Most often, the documents are being offered by the web server as text/html which is then rendered as a ton of garbage on the web user’s screen.

The best way to resolve this is to add all the MIME types to the server’s main configuration. IIS7 for Windows already has these MIME types set up correctly by default. IIS6 and IIS5 require the MIME types to be added, as might Apache on older installations. For Apache, there is also a workaround for the individual domain owner to add the mime types via Apache’s ..htaccess файл.

IIS 6 MIME type addition (for the Server Administrator)

Before this can be done, ensure that your server is also set to allow direct metabase editing:

  1. Load IIS Manager: Пуск -> RООН, “inetmgr” -> [добре]
  2. Right click the “сервер” and click “Properties
  3. Within theInternet Information Servicestab (usually the only tab), ensure that theEnable Direct Metabase Editcheckbox is checked.
  4. натисніть [добре]

Be sure to back up IIS’s configuration (тут for IIS5) beforehand. I won’t take any responsibility for an admin breaking his server. I have reason to believe this may also work on IIS5 however I have just as much reason to believe that it might just give lots of errors. If an IIS5 / Windows 2000 admin is willing to test this for me after backing up your configuration please let me know of the results.

Copy the following text into a file named msoff07-addmime.vbs and execute it once from the commandline by typing cscript msoff07-addmime.vbs and pressing Enter. If you run it more than once, the MIME types will be added each time and you will have multiple identical entries:

' This script adds the necessary Office 2007 MIME types to an IIS 6 Сервер.
' To use this script, just double-click or execute it from a command line.
' Running this script multiple times results in multiple entries in the
' IIS MimeMap so you should not run it more than once.
' Modified from http://msdn.microsoft.com/en-us/library/ms752346.aspx
 
Dim MimeMapObj, MimeMapArray, MimeTypesToAddArray, WshShell, oExec
Const ADS_PROPERTY_UPDATE = 2 
 
' Set the MIME types to be added
MimeTypesToAddArray = Array(".docm", "application/vnd.ms-word.document.macroEnabled.12", _

End Sub

Apache MIME type addition (for the Server Administrator)

Apache stores its MIME types in a file normally located at $installpath/conf/mime.types. See the mod_mime documentation for more on how it works. Arch Linux installs its MIME types at /etc/httpd/conf/mime.types і Parallels Plesk installs it in /usr/local/psa/admin/conf/mime.types. Your distribution might have it in another place, so find your mime.types file by running locate mime.types.

Add the following lines to your mime.types file:

application/vnd.ms-word.document.macroEnabled.12                          docm
application/vnd.openxmlformats-officedocument.wordprocessingml.document   docx
application/vnd.ms-word.template.macroEnabled.12                          dotm
application/vnd.openxmlformats-officedocument.wordprocessingml.template   dotx
application/vnd.ms-powerpoint.template.macroEnabled.12                    potm

application/vnd.ms-excel.addin.macroEnabled.12                            xlam
application/vnd.ms-excel.sheet.binary.macroEnabled.12                     xlsb
application/vnd.ms-excel.sheet.macroEnabled.12                            xlsm
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet         xlsx
application/vnd.ms-excel.template.macroEnabled.12                         xltm
application/vnd.openxmlformats-officedocument.spreadsheetml.template      xltx

Apache MIME type addition (For the domain owner with at least FTP accessusing .htaccess file)

Add the following text to your domain’s ..htaccess файл, most commonly in an httpdocs/ directory

AddType application/vnd.ms-word.document.macroEnabled.12 docm
AddType application/vnd.openxmlformats-officedocument.wordprocessingml.document docx

and my Personal Rating (PR) out of 10 😉

I use Firefox so most of these won’t apply to non-FF users. Однак, I’d be very very interested to hear what other addons my friends, subscribers, and random websurfers find interesting or useful to them. Have your say and let us know why you love the addons you love. 🙂

Personally, I prefer addons that aren’t intrusive. Ideally, an addon must have a minimal interface and give me a measurable benefit for me to keep it installed.

Cacheviewer – 7

This is a GUI front-end for the Cache Firefox keeps of the last few pages and media. I’ve found this addon more interesting than useful right now so I’m probably going to remove it soon.

ColorfulTabs – 9

I love the colours. The tab colour-grouping doesn’t work very well when you reach about 30 tabs though… :-/

завантажити Statusbar – 10

I prefer having everything in Firefox in a single window in tabs. Having a download box in a separate window is a big no-no for me. It also saves screen real-estate since it is very minimal. 🙂

Відео DownloadHelper – 10

Відео DownloadHelper шукає потокового мультимедіа – спеціально шукав для будь-якого великого контенту, який завантажується. При натисканні на іконку, він показує вам в даний момент-завантаження потоків і дає вам можливість поставити його в чергу, як “нормальний” скачати.

Так як ви ніколи не знаєте, якщо FF збирається до збою або влада збирається скоротити, Я б вважав за краще, щоб зберегти копію на мій робочий стіл, і я можу переглядати відео без використання більшої смуги пропускання для завантаження відео ще раз. також, на роботі, коли люди надсилають мені посилання на YouTube або інших засобів масової інформації, Я зазвичай не обтяжують дивитися до багато після того, як – в моєму власному дозвіллі або під час перерви.

Expiry Canary – 9

This neat and minimal addon tells you if the SSL certificate for the site you’re currently viewing is soon going to expire. If your own site has an SSL certificate, Я рекомендую вам використовувати цей аддон, щоб допомогти уникнути SSL сертифікату вашого сайту спливала через простого відсутності повідомлення або нерозуміння.

Fasterfox – 8

Fasterfox adds some network optmisation options. Some of the options could make your corporate network admin a little mad with you though. 😉

палій – 9

Для веб-розробок та експериментів зі сторінками. Дивовижний для тестування маленькі шматочки коду, а також налагодження сторінок.

FoxClocks – 6

errtells you the time in other time zones. o.O Was useful for a short timenow its redundant since my head is working it out faster than I can glance. rm -f

FoxyProxy – 9

Дивовижний для перегляду конкретних сторінок за допомогою конкретних проксі-серверів. This is useful for when some sites are blocked or the Saix Transparent Proxy servers aren’t working properly. 🙂

Я використовую це для маршрутизації трафіку через деякі проксі-сервери, які я не хотів би пройти через маршрути за замовчуванням. Its also very flexible. Якщо у вас є більш ніж один проксі-сервер доступний і той, який ви зазвичай використовуєте раптово йде на мерехтінні, просто перейти до наступного. 🙂

Greasemonkey – 10

Right now, I use this only for the GooglemonkeyR сценарій. This script reformats Google‘s search results to your specifications and also has an option to show small thumbnail of the pages Google links to. Greasemonkey can do a lot more and there are plenty of scripts readily available for many many sites.

Live HTTP headers – 8

I’ve used this a few times to diagnose gzip compression issues with IIS web servers. Not much else to say though: It works.

Live PageRank – 10 (so faronly installed it yesterday)

This addon seems simple enough. It gets the PageRank from Google and shows it in the tray.

NoScript – 10

NoScript є дивним на блокування реклами. Її трохи дратує на перший погляд, так як у вас є білий список все сайти, які ви любите – but in the long run it is soooo worth it. 🙂

воскресити Сторінки – 10

Дуже корисно, якщо ви переглядаєте на сайт, і це трапляється вниз. Якщо веб-сайт є статичним-контент-орієнтованих то це робить його легко і швидко знайти зміст, якщо його кешуються онлайн.

Tab Mix Plus – 8

Awesome for if you have more than 7-or-so tabs.

ShowIP (using a version modified for work purposesdisplays company server’s canonical name when browsing) – 10

I cannot imagine the hell I’d have to go through to identify a server without this plugin. Okay, I can. Used to have to do this all the time. I eventually scripted it but I can’t find the original script. Here’s my 60-second attempt at recreating what was in that script:

$ cat /etc/hosts | grep `dig A $hostname @mycachingnameserver | рукоятка . | grep -v "^;"`
$ dig -x `dig A $hostname @mycachingnameserver | grep ^$hostname | grep A | \
  awk '/[.]/{print $5}'` @mycachingnameserver | рукоятка . | grep -v "^;"

Web Developer – 9

I used this once to diagnose some issues with a page. I don’t do much web development so I’m going to remove this one. Its no comment on its capabilities since I believe this is a top notch add-on якщо you’re doing a lot of web development work.

Some of you may already know that I built a home server not too long ago. I documented some of the very important parts of how it was built though I was planning on releasing all the documentation all at once. I was using Arch Linux and I hadn’t nearly finished everything, especially the documentation. Наприклад, it was supposed to be a media server. After some disk shuffling, it was supposed to end up having a RAID1 for the boot and RAID 10 for the rest (the media part).

This didn’t work out at all.

I got as far as having an efficientдобреfirewalled) routing gateway server. I was finally satisfied that the customised local routing* was working correctly and I was confident that my tests with DHCP meant I could disable the DHCP service on the flimsy ADSL router and have all my flatmates start using the server as the Internet шлюз. Instead: I was logged in to the server from the office, I’d just installed Apache2**, and I was about to consult with a colleague regarding getting nice graphs put together so the flatmates could all see who was using up the bandwidth***when I noticed a little message indicating that the root filesystem had been remounted read-only due to some or other disk failure.

And then I lost my connection to the server.

And then I gained a foul mood.

🙁

When I arrived home, I found that, as I had guessed from the descriptive message given at the office, the (дуже) old 80GB IDE disk that I was using for the root filesystem had failed. Unfortunately, the server would never boot again and there was little chance of prying everything off onto another disk to continue where I’d left off.

I’m buying a replacement (SATA) HDD this next weekend just after pay dayand I’ve changed my mind about documenting my progressand backing up my configurations:

Release Early. Release Often.

* ISPs in South Africa charge less (easy price comparison) для “local-only” (within South Africa) traffic on ADSL but only if you use an ADSL account that CANNOT access web services outside of South Africa. This means that if you want to take advantage of the reduced costs but still be able to access the Internet at large, you need to set up some sneaky routing.

** one-command-install: ~$ yaourt -S apache

*** Internet Access in SA is expensiveyou get charged about R70 ($7 / £4.9 / €5.46) per GB when using ADSL, or about R2 per MB if using GPRS / 3G.
