Узнать код бронирования PNR в Аэрофлот

При покупке билетов на рейсы Аэрофлот у лоукостеров (обычно всё же выходит дешевле :) посредник стандартно выдаст вам номер брони, номер заказа, но не внутренний код бронирования Аэрофлота PNR, что надо вводить на сайте http://www.aeroflot.ru/cms/online_registration. Так вот, извлечь этот номер можно на одном из этих сайтов систем резервирования:

• http://classic.checkmytrip.com
• http://www.viewtrip.com
• http://www.virtuallythere.com
• http://www.myairlines.ru
• https://mytripandmore.com
• https://www.tripforyou.net

Так, когда заказ идёт через supersaver.ru, то помогает поискать свою бронь по его номеру брони на первом и втором сайте из списка. Если вы покупаете в долларах, также рекомендую попробовать expedia.com, места в нём можно забронировать сразу, даже на Аэрофлот!

Network Folders work slow in Windows 7

These steps helped in my case.

1. Rename registry folder HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\RemoteComputer\NameSpace to something else, like -NameSpace.
2. Run netsh interface tcp set global autotuninglevel=disabled.
3. Restart.

Can't read 32 Gb SD Card with Ricoh Reader on Lenovo ThinkPad W520, T430s, and others

I had lots of trials and errors with this, but here is the solution for Windows 7 x64. Please do all the experiments with clean SD-card, or you might loose your data on it! Just believe, if you fail at one of the steps, then you'll loose your data.

1. Google for Ricoh_Card_Reader_2.25.17.01, install and reboot. Official Lenovo's http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS028931 simply don't fit, and even drivers for T431s http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS034692 won't fit, they are 2.14 only, very obsolete.
2. After insertion of your SD-card, go to Device Manager, locate your "Disk drive" and set "Better performance" instead of "Quick removal". Otherwise you will have terrible lags and fails while opening the card. If you still have lags, try deactivating your security software, especially Microsoft Security Essentials.
3. Also check that you have "Integrated Smart Card Reader" in "Smart card readers" , but not some default device. If not, please update the corresponding driver online just from Device Manager. Otherwise you may find your data on the SD-card damaged!

Overlay icons limit

Installed some new stuff like SkyDrive and lost your overlay icons for TortoiseSVN? That's because of the overlay icons limit in Windows 7 — no more than 24. You can fix this only by removing some of the registered overlays from here:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers
0Ynd is for Yandex.Disk overlays.

String as a template parameter in C++03

So you want to instantiate your template with a string literal, but you can do this only by defining it as a constant. This code should work:

#include <iostream>
template <const char* p> Foo () { std::cout << p; }
extern const char s[] = "Hello world!";
void main () { Foo <s> (); }

The tricky part here is extern for s. C++03 requires template arguments to have external linkage. I can't remember any other reasons for using extern const in production code. The reason is that the C++ specs in that point are simply over-restrictive. Fortunately, C++11 doesn't have such a mess.

"Director of technologies propagation"

There is a guy in Yandex who's name is Grigory Bakunov, and he is somewhat legendary person among the Russian developers community, more on him here:

• http://habrahabr.ru/company/yandex/blog/210638/
• http://habrahabr.ru/company/xakep/blog/205832/
• http://ria.ru/generation_s_interview/20131014/969847973.html

He is a person of broad expertise, so there was a problem with a title of his position after he had turned his career into Yandex. Therefore they have invented the title "Director of technologies propagation". It means that he is responsible for revealing the value of technologies being invented inside Yandex to make them a) usable and available across different teams in Yandex, b) known and popular outside Yandex (through API's, competitions, etc).

What I want to notice here is that such a role is strictly important in science-intense working environments. Each IT-person in the company should be aware of what his/her colleagues are working on, and what technologies does the company already have to be reused. That is an essential part of the overall company's efficiency and the key to elaboration of the company's "school".
