Hosting Grumpydev Imageflair locally – part 2 – trying to get the text and images to display
Posted by jpluimers on 2017/04/12
Blank imageFlair
Hosting Grumpydev Imageflair locally ended with two issues left: an empty image and my wish to include more complete StackExchange bits like the current StackExchange flair does.
I thought fixing the empty image would take a rainy day. It actually took a few rainy hours.
No text
The culprit is that I didn’t have the Microsoft Core Fonts for the Web installed. Which was no coincidence as the free download of those from Microsoft terminated in 2002. The upside is that because of their licenses, they are available as open source and most linux distributions have a script package that will download these fonts. OpenSuSE has fetchmsttfonts for this.
Alternatively, you can use the web.archive.org to download manually, but that’s a tad tedious. But if you love tedious: Free downloads – TrueType core fonts for the Web.
zypper install fetchmsttfonts
That installs the fonts in:
/usr/share/fonts/truetypeThe drawback of having fetchmsttfonts is that the original Microsoft versions of these fonts are downloaded from corefonts.sourceforge.net each time the fetchmsttfonts package is updated, potentially overwriting newer versions of the fonts in that directory. If you don’t want that, use the trick at (not yet archived at the WayBack machine) font handling – install fetchmsttfonts, copy fonts, rpm -e fethmsttfonts, copy fonts back.
Having the fonts installed, I thought the only thing I needed to fix were the multiple references in config.php from that pointed to Arial.TTF. I took the poor man’s approach and just did this being in the directory of config.php:
cp /usr/share/fonts/truetype/arial.ttf Arial.TTF
Filled Imageflair
That didn’t work either: still no text showed.
So I decided to run imageFlair.php from the command line after setting $imageflair_debug = true; in config.php which then resulted in all sorts of warnings like
PHP Warning: imagettftext(): Could not find/open font
After reading I decided to build a small php-gd.tester.php script containing phpinfo(); and gd_info showing these portions for PHP GD (non-relevant bits stripped):

Too bad though: no information on where it sources the fonts from.
No image
Having no solution for the font rendering yet, I focussed at the lack of profile picture.
In the past, the images were generated with gravatar information in the JSON, but now that is empty. See for instance the output of http://superuser.com/users/flair/1.json versus his image http://superuser.com/users/flair/1.png

| } |
That reveals quite a change in the JSON that imageFlair expects. Actually there is a lot of HTML in there.
So decided to try http://superuser.com/users/flair/1 in addition to http://superuser.com/users/flair/1.json with this result:

Two downsides here:
- This doesn’t work for the combined stackexchange flair: http://stackexchange.com/users/flair/1.png works, but http://stackexchange.com/users/flair/1 gives a 404.
- Rendering HTML servers side to PNG requires a lot of work.
Time for another rainy day (:

Windows batch file – setting space as delimiter when parsing files
Posted by jpluimers on 2017/01/04
for /f "tokens=* delims= " %%f in (myfile) do
If you put delims as the last parameter, then an ending space will be included as delimiter (at the start or in the middle it won’t).
A great tip by jeb and Joey in an answer for windows – Batch file FOR /f tokens – Stack Overflow

Stack Exchange – Android Apps on Google Play
Posted by jpluimers on 2015/11/18
I missed when the StackExchange App for Android was finally launched, but I totally agree with Paul Lammertsma:
Exceeds expectations This was a long time coming, but it didn’t disappoint. It’s a great aid for a regular on Stack Overflow like me!

Instantly save a web-page to the Wayback Machine (Internet Archive: www.archive.org)
Posted by jpluimers on 2014/11/24
Saving a web page for posterity is really easy: just prepend http://liveweb.archive.org/ in front of the URL in your browser, then open the page.
The Wayback Machine (Internet Aarchive) wil instantly archive it.
See this great answer by Jeff Atwood quite a while ago:
One thing that the ineffable Jason Scott just pointed out to me on Twitter:
if you give the url of the page to http://liveweb.archive.org and wait five minutes, it will archive that page. How about that?
Also you can enter
http://liveweb.archive.org/http://www.website.com/pageto have it happen without visiting the page.So if you want to ensure that a popular soon-to-be or may-possibly-be deleted question gets archived by the Internet Archive, manually feed them to the URL above.
I suppose for already deleted questions, we could also undelete, wait 5 minutes, let it archive, then re-delete.

StackOverflow/StackExchange: two queries to help me improve my questions and answers
Posted by jpluimers on 2014/09/05
On the StackExchange network, I try to keep track of the questions I asked, and answers I gave in order to see if they need follow up.
For instance, questions with answers that have no accepted answer usually indicate there is room for improvement.
On my own questions, it means I could accept an answer, or give out more information on how to better answer that question.
On mu answers to questions from others, it might mean I need to improve my answer, or comment on his question to explain it better.
The first category can be queried easily by the built in search capabilities:
http://stackoverflow.com/search?q=user%3ame%20is%3aanswer%20hasaccepted%3ano
- the ‘me’ indicates it will use the account you are logged in
- replace stackoverflow with superuser, serverfault, apple.stackexchange, etc (stackexchange requires a subdomain)
The second category requires the Stack Exchange Data Explorer (SEDE) to execute some SQL:
My answers to questions that have no accepted answer – Stack Exchange Data Explorer.
- Replace the ‘me’ with your StackOverwlow user ID
(for StackOverflow.com, you can get that from http://stackoverflow.com/search?q=user%3ame as it will be listed in the search box there) - replace stackoverflow with a mnemonic obtained from the main SEDE page (click on the icon you are interested in, then copy that part into the query)
Note some questions (like Wiki: Current state of the art of Delphi 3rd party TCP/IP components libraries – Stack Overflow) are not suited to have one ‘best’ answer.
Note the SEDE can be addictive. If it is starting to become that way, perform a Jon Skeet comparison.
Note the SEDE data is usually at least a few days older than the live data.

Where to watch for StackOverflow / StackExchange downtime status: @StackStatus, @TechCrunch, @HNTweets
Posted by jpluimers on 2014/02/17
Basically, stackstatus.net is not actively updated when severe things like DDoS happen. So the best way to be kept up to date is watch these links:
- StackExchange Status (StackStatus) on Twitter. Not many updates, but at least some updates.
- TechCrunch. (@TechCrunch) They posted Stack Overflow Goes Down, Programmers Around The World Panic (It’s Back Up Now) | TechCrunch.
- HackerNews. (@HNTweets) They posted Stack Overflow is down | Hacker News.
- IsItDownRightNow. They have some sort of uptime history graph at Stackoverflow.com – Is Stackoverflow Down Right Now? and know that Superuser.com – Is Super User Down Right Now? is related, but not that Stackexchange.com – Is Stack Exchange Down Right Now? is related.
- IsUp.me. No history, only a current status like Down For Everyone Or Just Me -> Check if your website is down or up?.

Windows Timer Resolution: Megawatts Wasted (via: Random ASCII)
Posted by jpluimers on 2013/07/11
Don’t increase your Windows Timer Resolution. And keep an eye on programs that do:
Raising the Windows timer frequency is bad. It wastes power and makes your computer slower. Routinely doing this in all sorts of programs that end up sitting idle for hours really needs to stop.
You can use ClockRes to monitor the time resolution and what programs changed it.

c# – What’s the hardest or most misunderstood aspect of LINQ? – Stack Overflow

It is such a pity that StackOverflow is not the place any more for questions like these:
c# – What’s the hardest or most misunderstood aspect of LINQ? – Stack Overflow.
These questions and answers historically got me most of the insight from SO.
Alas, no more.
