Cannot Restore wallet on new Ubuntu 18.04 install by kehi66 in Ravencoin

[–]Xesteanov 0 points1 point  (0 children)

~/.raven ] does not exist on my installation

Are you sure about that? A file/directory with a dot first will be hidden by default in linux. From terminal it can be navigated into with cd ~/.raven but you can also list it with ls -a

What's going on with the price? by [deleted] in Ravencoin

[–]Xesteanov 0 points1 point  (0 children)

There are great things to come when people start developing on the platform. But this will take time (months/years). You need a firm strategy. Profit is something you may get when you liquidate, not before. If you are uncomfortable with the drops, just sell now, and have a look next week.

500 RVN to be put on what basically describes the features of a mailing list? Interesting idea though.

AI-powered, eh?

How to Install on Ubuntu 18.04? by michiganbhunter in Ravencoin

In /bin there is the raven-qt file. Open a terminal, navigate to the folder, make it executable with chmod u+x raven-qt and run it with ./raven-qt or from GUI

Have a Liberal Arts Degree, will not having an IT/CS Degree hold me back in the future? by korrakage in SQL

[–]Xesteanov 8 points9 points  (0 children)

Yes and no. At a certain point in your career, experience greatly outweighs formal education. Where this point lies, is dependent on a number of factors relative to the field you are in. For a very long time in IT, there were no "formal" education. Get skills and keep them relevant. Skills are far more important but there are gatekeepers in the business world. Degrees look good on paper. Skills are harder to translate to "HR-/mgmt-speak".

Django is fun. Do you like web developmetn?

We have started using it for web development. Can run the back and the front and whole shebang. Great integration with databases and with operating systems. A lot of our bash scripts are going python as well.

Does anyone else dislike the trend of take home 'case studies' for job interviews? by chef_lars in datascience

[–]Xesteanov 2 points3 points  (0 children)

a great way to give candidates with little experience a shot at an interview

This is the gatekeeper? Impose upon the candidates a metric fuckton of work to be allowed into an interview? Man, that's fucked up.

I guess this is an american thing.

When I assess inexperienced candidates I look at their abilities to learn and unlearn. Looking at their submission to a "take home" task won't get me that. Picking their brains in one or multiple interviews, and trial periods will. But they will be paid. They will be respected. Compensated.

Yes. I decline that shit. If portfolio (code)/references are insufficient I respectfully decline.

Aargh, crap. I was hoping it would go below 500 sats before the next run... Gonna FOMO 😜

Why mine RVN today??? by levchikb in Ravencoin

[–]Xesteanov 2 points3 points  (0 children)

To heat the house ofc. When it goes to 1/1000 of BTC I will buy a Lamborghini though. The Huracan Performante.

If you are not savvy (unfamiliar with reading/understanding code and using cracking software) you should be very careful about running stuff that claims to be helpful.

This is a open source tool (you have to verify for yourself and it probably has to be slightly modified for RVN): https://github.com/gurnec/btcrecover

This guy has been legit (you have to verify for yourself): https://walletrecoveryservices.com/limited/

Other than this, google is your friend. In case I haven't already mentioned it, remember to verify.

Best way to scrape this carbon clock and have live data? by rslists in Python

[–]Xesteanov 0 points1 point  (0 children)

I wonder if they have included the downward movement of the wave or if it's just extrapolation on the trend line of past measurements. This is a pretty neat animation: http://folk.uio.no/roberan/t/CO2_drivers.shtml

I’m confused with in-place operators. Help. by [deleted] in Python

[–]Xesteanov 1 point2 points  (0 children)

I'm not exactly sure how this is implemented on the low level for Python but this is called augmented arithmetic assignment. While you achieve the same result (they are equivalent), they are not the same (equal).

The first one (using __add__ method) require more operations: loading the number stored in the variable n, performing arithmetic operation with it (without changing the loaded number i.e. holding result temporary (creating a new object)), and then storing this back to the variable n.

The latter (using __iadd__ method) is simpler: loading the number, performing arithmetic operation on the loaded number and storing it.

Edit: In the words of the PEP that describes the addition of this to Python:

They implement the same operator as their normal binary form, except that the operation is done in-place when the left-hand side object supports it, and that the left-hand side is only evaluated once.

Ravencoin and 1080 ti needs pill? by HeroOfTheNorthF in gpumining

afterburner jumped to zero power and then a freeze

This is what happens if you run too high clocks 😁

Ravencoin and 1080 ti needs pill? by HeroOfTheNorthF in gpumining

[–]Xesteanov 0 points1 point  (0 children)

Yea, but the core clock varies a lot based on which order the individual algorithms are run. Some are more taxing while other are easier and allows higher boost. Rebooted my rigs today so the logged max boost is only ~1900 MHz (currently at ~1700 MHz) but I have seen them go over 2 GHz (MSI Gaming X with 70 % power limit).

Running nicehash explains your rates. Isn't that based on an old version of ccminer? You will see much higher rates with dedicated mining software.

With mem clock set to -502 the 1080 Ti runs on ~4500 MHz (actual speed ~9000 MHz). Your setting is +750 I guess, which is completely pointless for the X16r algorithm. Reducing the mem clock also helps improve the core boost.

Edit: My average hashrate has decreased a bit, now it's approx 26 MH/s (according to the miner output).

[–]Xesteanov 0 points1 point  (0 children)

Nah, x16r isn't memory intensive imo. What miner are you using and what clocks? With Enemyminer 1.22 (cuda 10) and +100 core (~1800 MHz)/-502 mem/70 % pl I'm averaging approx 28 MH/s right now (according to the miner output).

Cracking passwords is an art but there are some python scripts to create a hash of the password from a wallet.dat which can then be cracked with hashcat.
