How come this crap creeps in for so many years?!

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),
 LC_CTYPE = "UTF-8",
 LANG = "en_US.UTF-8"
 are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

First of all I really have a hard time getting around the fact that I see this on every default installation of Ubuntu (I bet I saw this on Debian too) for so many years and versions…

And I’ve seen a number of useless suggestions on how to fix it. dpkg-reconfigure this, dpkg-reconfigure that, install this, remove that. Generate this, edit that. And so on.

$ sudo echo 'LC_ALL="C"' >> /etc/environment

fixed the crap at last… at least for me… YMMV…

Raspberry Pi, hub USB 3.0, error -71

If you have a USB 3.0 hub connected to your Pi and devices plugged into this hub are not configured properly, you check the logs and you see something like

device descriptor read/64, error -71

around USB activity – chances are that you ran into the same problem as several people, including the author of these words.

The conclusion is that USB 1.1 devices, connected to USB 3.0 hub are not working correctly in such configuration, due to a bug here or there, even if the very same hub, with the very same devices works well when connected to something else than Raspberry Pi. A workaround to this is to add an entry inside /boot/cmdline.txt


which forces the whole bus to 12Mbit/s USB 1.1 speed and lets you configure and use the devices.

Fix Finder’s contextual “Services” menu

I sometimes add or remove “services” to my ~/Library/Services directory. Unfortunately this alone doesn’t make the changes being reflected in the menu…

It might be caused by the fact that I keep things I want to have on all machines in a Dropbox folder and link to it. Or it may be due to some other reasons. In any case. I am not alone as this old hint shows. It was posted in the times of the OSX version 10.6. At the time of writing I use 10.9 and the problem remains. Luckily almost the same solution applies. The only difference is that one has to add an option to the command:

/System/Library/CoreServices/pbs -flush

should do the trick and bring your “Services” menu back to what you want it to be.

From the

$ man pbs

pbs is an agent for the Services menu.  It scans for and vends available Services, to populate the Services menu [and] is NOT related to the pasteboard.

Who would have guessed?

HTTP query strings in Laravel routes

So you read the documentation back and forth, and again, and even more again. And you still can’t make your

Route::get('myroute?querystring=myquerystring', function()


Well – you don’t find it in the docs but what you have to do is:

Route::get('myroute', function()
    $myvariable = Input::get('myqueryparameter');
    // do whatever you want with the variable now

Why git is sometimes more gitty than any other git you are ever about to encounter…

So you work on a project which is version controlled and moreover it is version controlled by the almighty git himself. No matter whether you just got around all the teething problems and a steep learning curve of using git or you are a seasoned git professional – at one point or another you may find yourself in a situation where you want (or need) to:

No problem – you say? Sure – no problem as you can see if you follow the links above – nobody has ever got any problem with any of those operations. And no – using

$ git --follow

is not a solution either. Neither one knows when/where to try using some extra command line switches nor can one do it with non-command-line interfaces.. And no, unless you are a git geek, don’t even try to follow the discussions on those topics out there. The closest to something, which I felt could somehow work were a few discussions involving “filter-branch” command of git but God only knows what those dudes were really talking about. You know, this single big PITA alone can make one scream “GIVE ME MY SUBVERSION BACK!!!”

And you think there are no heroes anymore these days, don’t you? I tell you – There ARE! This awesome dude somehow made something out of this whole pile of conflicting, half-truth, semi-baked, scruffy-looking “advices” or just studied the matter on his own ;-) and came up with a shell script, which does the hardest part for you. I tried it. Sure I made a fresh pull to be up to date as action zero. Then backup of the whole directory first, then –dry-run second, then

$ git-mv-with-history myfile=mysubdirectory/

Don’t forget the trailing slash if you want to move the file to a subdirectory or you may end up with your file being renamed into what you wanted a directory to be named!

I eyeballed all the files (checking them against the original clone of the repository) and the git status results..

silverdr$ git status

On branch master

Your branch and 'origin/master' have diverged,

and have 110 and 110 different commits each, respectively.

(use "git pull" to merge the remote branch into yours)

DON’T! DO! IT! I meant don’t “use git pull to merge the remote branch into yours”! Unless you want to ask for trouble, that is. Don’t try to simply push the changes either (but since your push will be most probably rejected anyway – it shouldn’t at least do much harm if you insist and try anyway). Now – what I did and it worked (but remember: YMMV!!) was:

silverdr$ git push --force origin master

Counting objects: 428, done.

Delta compression using up to 8 threads.

Compressing objects: 100% (398/398), done.

Writing objects: 100% (409/409), 562.33 KiB | 0 bytes/s, done.

Total 409 (delta 154), reused 0 (delta 0)


+ e1ea07c...8879fe2 master -> master (forced update)


YES – there are still heroes. Even these days…

Making Github’s “fork & pull” model palatable

When collaborating with other people using Github’s “fork & pull” collaboration model, it is a real PITA to have to re-fork and re-merge upstream repository changes all the time. The solution is to set your “forked” repository to use different pull (fetch) and push repositories. This way one can always pull/update from the upstream but keep pushing own changes (AND the upstream updates) to the forked repository of his own. This single, simple (when you know it and you know how to do it) step makes a major change in the efficiency and perception of the “fork & pull” collaboration model.

Give me my Save As… back!!

No, I don’t want any “Duplicate”. I don’t want to duplicate anything! The work I have done on the file makes it different than the original file. NOT A DUPLICATE! I want to simply Save [my work] As… [different file]. Understood, Apple?! NO, I don’t want to push Command + Shift + Option + S (thanks God somebody kicked your butt so that at least the function is back there again!) – this is not a convenient shortcut for one of the often used functions. Neither is fiddling with mouse and keyboard (alt key) at the same time. Will you get it?

So much for the rant. Now a (partial but still good) solution to this small part of Apple’s-After-Leopard loss of reason, by tjluoma:

$ defaults write -globalDomain NSUserKeyEquivalents -dict-add 'Save As...' '@$S'

Gosh… thank you TJ!
