Всем доброго времени суток, возможно опытные жители данного сайта могут помочь и подсказать. Есть необходимость каждый день выгружать csv файл с транзакциями с etherscan или ethplorer, кошельков 7-8. Каждый день занимает прилично времени.

Какими парсерами для этого пользуетесь вы? или возможно какой-то бот в телеге, а может даже свой софт
2  Alternate cryptocurrencies / Mining (Altcoins) / How to choose\check USED graphics card before buy. part II on: June 11, 2018, 12:13:28 PM
Hello my friends,

First part how to properly evaluate the graphics card externally: https://bitcointalk.org/index.php?topic=4416801.msg39350487#msg39350487

After you looked at the video card, if nothing has alerted - we go further.
We paste it into the computer, connect the monitor to the card and turn it on. You will need drivers, programs: GPU-Z , benchmark of type 3dmark and FurMark.

1. Install drivers if they are not present
2. We launch GPU-Z. We will consider GTX1060 3GB, because I found the screenshots from her.

We are looking for the characteristics of the video card, in particular the number of cores and the frequency of operation of the GPU and memory. All google in 10 seconds, here is an example of a table for some green cards:


Pay attention to the lines Cuda cores and Base clock, as seen for the GTX1063 is 1152 and 1506 respectively.

Now we looking at GPU-Z


Shaders this is Cuda cores. Shaders number should coincide. The frequency may vary slightly, depending on the acceleration by the manufacturer, but not by 50%.

Now look at the fake 1063


As you can see the name, the amount of memory is the same as on the real 1063, but the shaders and frequencies are very different.
192 cuda core has a card of 2011 GTS450, therefore, before us is a real fake, such tons are sold on Ali and ebay, and then they are resold to gullible people as a kind of real


Go ahead. Test. Running FurMark


The resolution is better to choose under the screen and include fullscreen. We press the GPU stress test and for 10 minutes we spin it.


The card should not make a whistle, restart the computer and give out errors. If a message appears that the video driver stopped responding and was successfully restored or the PC just turned off, we do not take a card.

We twisted the circle, it's time to start the benchmark. Better something more heavy, for example unigine superposition. In the settings, select the maximum memory usage and start.


Everything should be beautiful, without interference (artifacts).

 If there is artifacts such:


We do not take the card.

My opinion about the cards after the mining. As practice shows, the factory marriage gets out in the first months of using the card. In the case of mining, it will happen much earlier. If the card is used in mining, say a year, then it will work for a very long time, most likely it will simply become obsolete before it dies (if, of course, it was taken care of).
There is also a blade of a video chip, mostly the cards of 2011-2013, such as the GTX560 or HD6970, are sick, so I highly recommend that they not be bought. Without fear of dumping it is possible to take cards of 9 series and above for green and RX4xx and above for reds.

3  Alternate cryptocurrencies / Mining (Altcoins) / How to choose\check USED graphics card before buy on: June 04, 2018, 10:29:25 AM
Hello my friends,

first of all I want to warn - do not buy a card without checking, even if there is a check, the box and the card looks like new.

You met with the seller, in the beginning you need to look at the video card, pay attention to:

1) Presence of seals (not an indicator, because you can disassemble the card without damaging them)
2) The color of the textolite. If the card was being repaired, for example, the video chip was heated, the card would be slightly darkened\brown. It is best to focus on the white silkscreen, which is drawn around the details and written the names of the elements. First of all it darkens.

Left  example of a normal color of textolite(images from Google):


And right this is how it looks after repairs(They are more brown)

You can see with the naked eye the difference of the color shade. It is better to bypass these cards, because it is not clear what they did there and how long she will live. Here is another example of a repair card:

the PCI slot is darker than the rest of the textolite


3) If there is a possibility to look under the radiator, then it is worth to look there. Around the video chip should be clean (does not apply to memory chips, because many cards leak thermal pads).

On the left photo this is how a card looks like in which 99% of people have not repaired anything

On the right everything is clean, the edge around the chip is white and one shade. Well, even comments are superfluous. Do not take it in any way.


4) Also it is worth paying attention to all the stickers, everything should be evenly glued without any signs of dismantling. On the card there can't be no stickers, even on the cards with the backplane there is a sticker with the serial number.

5) Turn the fan with your finger, without fanaticism. It should spin easily and without unnecessary sounds, there should also be no backlash if you swing the blades sideways.



P.S.:
How to programmatically using GPU-Z, 3dmark and FurMark(or another software) to check the video card, I will not write here, there are a lot of guides/topics, if there are needy people, I will write

Update:
If some one will be interesting, I make part 2 guide on "how How to choose\check USED graphics card before buy". there I will explain how to test the graphics card programmatically

9  Local / Разное / Как продать свои старые прокачанные аки с  on: May 02, 2018, 04:57:33 PM
Уверен в том, что на этом форуме очень много людей играли в разные игры, и имеют уже ненужные прокачанные аккаунты. Так же как я.
Отдавать бесплатно жалко, а вот обменять\продать - все будут рады этому, но нету особо времени и желания разбираться в ценах, найти покупателя и вообще чтобы не кинули, короче много гемора, а аки пылятся.

Кто в теме, подскажите надежные площадки? или возможно схему таких продаж\обменов.  
10  Local / Разное / Как помочь развлечься пожилым людям on: March 15, 2018, 01:42:14 PM
Возможно каждый из нас часто сталкивался с ситуацией когда гораздо старший человек(возможно пожилой) просит установить ему каких-то игр на компуктер. Но проблема в том что таким людям чаще всего сложно разобраться в современных играх, и для них в основном подходят очень простые (чисто мышкой управлять) игры.
В моем случае подошли эти игры:

Блицкриг (2003) - только первая часть, вторая оказалась уже слишком сложной
call of duty 4 - банально побегать и пострелять

Кто какие игры знает для таких ситуаций?

The question to those who have long been in the crypto topic. PC protection is an important part of monitoring different ISO and others, even if all the keys are stored on a USB flash drive.
How to secure yourself more than usual? Maybe there are some special antiviruses, or extensions in the browser from phishing and illegal mining.
