So, after installing the router DIR-620 firmware dd-WRT , you can connect it to a USB flash drive or external drive via USB, install the necessary programs and receive in addition to the router - NAS with downloading torrents.
Mounting an external drive in the dd-wrt
First you need to enable USB support on the router through the web interface: Services - USB - USB Support - Core USB Support + USB Storage Support. scsi , где строки вида /dev/scsi/host2/bus0/target0/lun0: p1 p2 укажут на подключенный диск (в данном случае мой диск подключен к третьему порту USB-хаба – host2 и имеет два раздела – p1 p2 . After connecting the external drive to check the success by calling dmesg|grep scsi , where the lines of the form /dev/scsi/host2/bus0/target0/lun0: p1 p2 point to a mapped drive (in this case my hard drive is connected to the third port USB-hub - host2 and has two sections - p1 p2.

Set out to home wi-fi network to translate into modern encryption protocol - wpa2. It seems everything is very easy to be even in Linux - you put the wpa-supplicant, prescribe the point name, encryption type and key in / etc / network / interfaces - and it works. But no - fought for four hours, I tried different ways - can not connect my laptop to the network, although the netbook and smartphone easy to pick up her.
It turned out that wi-fi card in ThinkPad T40 does not support wpa2 (and wpa too) at the hardware level. I thought it was solely software solutions and had no idea dig in the direction of hardware support. As a result, had to change the card, good for e-bay sells them a lot. Read more »
It has long been thought about the need to make a home NAS (network drive) to be common to all the home computers (and now - and Smartphone) store music, movies, backups and some shared files that you want to sync between multiple machines . The idea of gathering another computer on something such as an atom after reflection has been abandoned - it turns long and relatively expensive, but certainly interesting. Therefore, I decided to look at the ready with the possibility of flash devices, specifically - routers that support dd-wrt/openwrt etc.
First stop on the D-Link DIR320 - which has already become a classic choice for a home NAS, as a simple and complete network solutions other similar tasks. Pros - very reasonable price, long on the market and already densely overgrown with all kinds of guides for alteration and improvement. However, it turned out that the store did not have it and I bought the DIR-620 - a more modern version of the 320 th. Otherwise, there is no much difference - DIR-620 also has the ability to rewrite party firmware, USB-equipped outlet (USB-host, to be exact) and costs about the same money (in my case it was even 70 rubles. Cheaper). Read more »
Accumulated a few simple recipes work in Linux, which are due to the low frequency of use can not remember by heart. While lying in the drafts - some more than once had to reread to remember how and what to do - the benefits are obvious.
The order of output arguments xargs
Once confronted with the problem of the order of substitution arguments xargs. And like the man revered, and Googling, and met the necessary key-I, but neither of mana, or from not understanding of Google was exactly what he is doing exactly what we need. So, the key-I specifies the desired output order of the argument in xargs, using substitution. xargs -I arg_name command arg1 arg_name arg3 - arguments when you run command will be displayed in that order, whereas in the usual case arg_name will be replaced at the end of the dialing string commands.
Read N lines from the beginning of the file
Together with the previous solution is useful reading from a file some lines that are then converted into a set of arguments. Banal cat is known to all think. Reverse Order - tac. Read N lines from the end: tail -n N . Similarly, but with the beginning of the file: head -n N (vozm. head is not in BSD-systems). And prochtitat rows X to Y: awk 'NR >=X && NR < =Y' Read more »
Ran into a nasty bug in the module Time:: Local (in my opinion, even in kukbuke described) - it seems that the month was inserted into indkes array directly, despite the fact that the numbering starts with zero elements and instead issued in January of February and for the bottom etc. Accordingly, some months were processed correctly, but some - called an error like this Day '31 'out of range 1 .. 30, which by virtue of the rarity it was difficult to detect.
But what prevented the author procteyshim way to generate a test calendar and get rid of it a module? Well would - "for themselves" do so at CPAN module is in the literature mentioned - and such children's bugs. With was still to version 1.13 to version 1.20 has not changed - the same goes through with the first item ...
About the service advertisement (and a set of followers) on Twitter, LiveJournal and Facebook - - Know, I think, for many. Quite a few common notes about how to make a Twight (earnings in Twight comparable earnings in GoGetLinks , instead of just links - Census and retweets). The only problem is the same - there is present at the time and postmoderatsiya withdrawal "outside" the administration will look on your blogging account. Hence, it is necessary to untwist or account for advertising, publicity or spoil your own personal blog. Neither one nor the other I do not want to.
There is another possibility to dispose of their capital on twite.ru - they can throw on your "Account advertiser," it does not need to be checked by moderators, funds remain in the system. The conclusion is simple - you can earn money on advertising your site using bots. And if the twitter account to add to the system as an advertising platform to promote a minimum, the elementary and Learn is added without any checks (though hyped LiveJournal Account issued naturally more attractive promotional offers.)

Tired of the gently become quite noticeable brake Gnome with Metacity and Nautilus in the company (my laptop is fairly old by today's standards - IBM ThinkPad T40 with a Pentium M 1,5 GHz and 1 GB of RAM on board), I decided to try Openbox. Created a test user, and gave him Openbox as a WM, a little set up, popolzovalsya hour and moved the main uchetku him.
The difference in speed of response on subjective feelings (which, incidentally, and it is important in this case) was just tremendous - a terminal emulator ( rxvt ) opens within seconds, vs. 7-10 seconds. a dwarf. The windows fold-unfold and within seconds, a dwarf with a dozen Firefox tabs open can turn out panels 3-5 seconds, all the while cracking HDD, which I also have no official. At the same Openbox indicator to the hard drive works quite rare (in general it seemed that the dwarf, with its "Registry" is getting closer to the windows - and the brakes have to accumulate over time learned to use).
Even Google Chrome feels out of Openbox earned more quickly (and is faster Firefox, which was not under Gnome), although it may have self-deception on the wave of general euphoria of the lightness and speed of WM. Read more »
Was surprised to see that e-mail addresses of users of service "answers" at mail.ru stored in the code page in the clear, as the dawn of the Internet directly. No attempt to hide the addresses - even strange in our time. You can easily and naturally to grab email database for future brute force passwords to them, or such spam (since the service is the category - and likely the target audience can estimate on them).
In general, all done very primitively, in the good old shell, without a different fashion Multithreaded grabber from the cloud (cloud to brute force way must be very interesting):
-wget-q-O -
As you can see - I rip to test the first 10 pages of open responses received as a result 197 unique addresses. In principle, the speed and convenience, you can each category in a separate process to download, with the sort of results after boot directly from a file.
At last Tuning regular season under grep to search for email-addresses.
UDP: under the cut for example, posted a simple script in bash , which parses some of the pages in "Computers and the Internet" with Otvety@Mail.ru and decomposes received e-mail addresses by category. Its easy to add all the same envelope by regular means to automatically bypass the tree sections and parse e-mail addresses of all categories.
Yandex pleased nedovno (ie - September 13 this year) running (For androyd Market and iPhone appstore under - .) Popolzovalsya - was pleased, really comfortable.
On the subject search market as such there is no - you can only go by category, flipping through everything. So to find some kind of thematic softiny I went to the forums and looking 4pda there, then hammered the title or barcode on your phone and only got the desired result.
Lookup service uses HTML5 and therefore earn, not all browsers (eg Opera Mini to work declined only in the standard browser androyda). Phone model determines automatically which is convenient. For the selected application will appear and reviews, screenshots Market. After selecting the installation throws on the market and the whole process goes as usual, followed by a return to the search box.
With no iPhone - I can not say how justified such a search for him. By now he was androyd for me is quite convenient, but that's how long such functionality is not implemented by means of the market - a question.
Not so long ago was talking about his remake automotive compressor eagle R17 (fasten him as "remote control" that the creators of some reason, ignored, although the design of compressor downright screaming about the need for it - Remote control for motor compressor eagle ). But in the further installation of the compressor directly to the car - collided with a small, but very troublesome problem.
Prevented finish the simple lack of available right power connectors - two veins cross-section up to 2.5 square each. To the fact that different tools and equipment needed to fly directly from abroad, I have long been accustomed to - leaves a lot cheaper and without suffering from canvassing endless "online shops" where necessary thing is present in a price and not the fact. But with electronics until then everything was pretty good - though more expensive than the same Chinese directly, but if something is urgently needed - you can go out and buy. As it turned out - not all. Such a trivial thing as connectors, has been found.
During the fruitless searches visited two of the auto market, several auto parts stores and electronics stores. Found on the internet sites of companies allegedly selling the right connectors - e-mail reply does not deign - no longer wanted to call. As a result, the necessary connections have been detected for 20 minutes overseas and yet 5 minutes booked. If I did not try to support domestic "manufacturer", impotent, and immediately turned to those whom we have long been "overtaken and outstripped and left far behind" - would have long since received the necessary upgrades and finished vehicles. Morality is not all it is quite obvious ...
