The E-Aadhaar Card PDF which can be downloaded from the UID Authority of India contains a signature and some brain damaged verification code. In the middle of the page on the right side it shows “Not verified”, a yellow question mark and some more text about the digital signature. This question mark has to be clicked which then verification process. When this process is finished the question mark is replaced by a green tick and the text reads “Signature valid”. Since everybody just prints the page and deletes the file this verification process is completely superfluous. Since a smart ass wanted to save some money these documents are not signed by a proper key which makes the whole process a bit cumbersome.
The following steps show how to download the Aadhaar Card and convert it to a nice PDF:
wget -q -O - \
| wc -c
Another big problme is, that the code is written by gardeners or lumberjacks, but not by IT professionals. The bugs in the code make it very unreliable. For example on Aliexpress I get the following message pretty often:
Due to network reasons , adding that fails, re-click the "Add to Wish List". But clicking “add to wishlist” again and again and again just results in the same error message. The only thing that helps is reloading the page.
- makes the webpage loading slower,
- causes more load on the server,
- causes more costs for the bandwith of the server,
- and uses up the megabytes of my connection which I have to pay!
- There are probably a lot more…
This article in theguardian.com animated Golem to their office temperature measurement project (german). And this in turn convinced me to connect a temperature sensor to my Alix board at last.
Sometimes systemd feels the urge to wait 2 minutes for some service which makes troubles and then continues to boot or shutdown. Two minute timeout is hopeless insane for this default configuration, even 5 seconds feels like endless waiting.
The timeout can be set in
/etc/systemd/system.conf. Just add the following lines or change them if they already exist:
This Avahi mDNS daemon is for zeroconf. Just uninstall this bloody crApple rubbish:
apt-get remove --purge avahi-daemon
Another annoying delay is caused by the network code trying to get an IP address over a NIC where no cable is plugged in. I have no solution for this problem yet, but with lower timeout it’s not that awful anymore.
Yesterday I stumbled upon a post about free whatsapp softwares. So I thought I give it a try. After some initial troubles and a lot of startpaging I finally got it running.
Today I got an email with link to a facebook page. Actually I’ve seen this link before but ignored it because it links to facebook. But today I opened that page. I was reading a bit, following some links to other pages, coming back, reading more. And suddenly I got this:
This sucks. Why should I login after this page has been showed for 5 minutes? Additionally you can see how completely retarded facebook is: The text on the page is in german, some navigation help texts are in Kannada and the login window is in english.
First I thought “facebook sucks” and started searching for other complaints about facebook. But facebook (and google+ and twitter and…) collect all the braindamaged morons which were annoying everybody in IRC 10 years ago. Now IRC is again the nice and friendly place it was 20 years ago.
Thank you Facebook!
What is worse than a battery powered multimeter?
A battery powered multimeter with an empty battery.
That’s why I have to upgrade this multimeter with a power socket, a step-down converter to support a wide input voltage range, and an isolated DC-DC converter to isolate the input voltage from the multimeter circuits.
Four years ago I enjoyed flying with Qatarairways. But quality of their service has been sinking since then. Also if I compare with other airlines which do not claim to be five star I see a lot of potential for improvement:
A friend gave me a link to an ELV product which I copied and pasted into my browsers URL bar. ELV then presented me with this completely useless warning on their webpage:
Additionally they set a shit load of cookies. Obviously one or more of them are used to prevent this retarded warning.
I wonder why should I run an anti-virus program when I access a website? Especially when my browser is running on a Linux box behind an OpenBSD firewall? I’m sorry but I haven’t seens something this retarded ever.
So my recommendation is:
Fuck ELV. Never ever ever ever never ever buy something from ELV!
Also don’t visit their site, block and delete all their cookies.
