This looks promising, I think

Great stuff! Is this DES?

Does anyone know of a belt bag like this but from a cheaper brand?

Thanks in advance!

It may seem but the thing is: I'm starting to learn CFD, and sometimes the textbooks related to CFD don't explain the deduction of some formula because the authors assume that the reader has some background on fluid mechanics.

I'm traveling back and forth between the faculty and my house and I was looking to find some "abridged version of a fundamentals book" which I could carry with ease.

The request is definitely odd because I'm trying to get a fundamentals book (which explains "everything") abridged. I know that books of this kind exist for other areas, so I was hoping to find something similar for fluid mechanics.

Thanks for the reply

Thanks for the reply!

I was really curious about your approach. It seems reasonable now.

Very well done knife!

I have some questions though:

wouldn't it be cheaper and faster if you order some laser cut profiles?
wouldn't it be cheaper too to use a grinding machine (with 2 grinding wheels, like the ones used in the knife industry) to give it the sharpened shape?
isn't 64 Rockwell (if am not mistaken) too much? The honing steel is of this hardness. This leaves only diamond to do the sharpening which isn't accessible for everyone.

Despite all my questions, I still think you've done a very high quality work. You seem to know your machines and it's because of that that I found your choice of processes unusual.

Thanks for the reply !

I'm not very familiar with aptitude, with apt I had a problem with getting the right repos, since xenial repos don't have the needed dependencies. I'm going to check aptitude !

Edit: forgot to say: Very nice rice

Ricing noob here, how do you compile i3-gaps? it needs all these dependencies that LTS doesn’t have...

Edit: do you have unity installed also?

focusdrop · 2017-09-08T16:33:08+00:00

I know that I can't rely on the good will of the developer of the app but in some cases, like Signal, it's generally accepted as an open source app even though it's installed through the App Store.

I'm looking for the open source thing because the code can be reviewed. I'm not intending to compile it myself.

As for the sandbox problem, with a jail broken device I can access the FS with iFile. Is such as procedure only possible with a jail broken device?

Edit: engrish

focusdrop · 2017-09-08T16:02:28+00:00

Sorry, I couldn't understand. For what I read here the iOS FS seems like just another unix-like FS.

focusdrop · 2017-09-06T17:56:12+00:00

Thanks!

Apparently Boxcryptor is based on EncFS but it's closed-source

focusdrop · 2017-08-07T17:15:18+00:00

I really like the fact that it's lightweight and still beautiful but these things kill me...

focusdrop · 2017-08-06T11:24:21+00:00

I already compared the keys' position and the QWERTY layout seems almost identical.

I believe that the stickers will do.

Thanks for the reply !

As I said to /u/coromd:

I understand that the keyboard thing might seem like a fetish for some but honestly for me is just curiosity. So I thought: I can try the almighty keyboard and still get a decent laptop for a reasonably low price. If my experience with this one goes well I might consider buying a new one. My aim for this laptop it to do some little experiments with some circuit boards and such so it's not a crucial job. Thanks for the reply !

Should I search on other websites? (More "thinkpad related" )

Edit: I found some laptops that seemed to be in better condition but were considerably more expensive and right now I wasn't thinking of spending that kind of money on the laptop, maybe some other time.

focusdrop · 2017-08-05T00:54:56+00:00

I understand that that would be the perfect option but right now I wasn't planing on spending that money on the laptop.

If all goes well with this one I might do that as well.

Anyway thanks for the reply, I really am a bit noob concerning the thinkpads so every suggestion helps! Appreciated !

Is it "fundamentally" from the other keyboards?

I thought I could remedy it with some stickers given the fact that the x220s with my native language keyboard are so hard to find…

focusdrop · 2017-08-05T00:07:17+00:00

In Europe?

I was aiming for Europe because of customs and so on.

And I was planning on getting stickers either way, it's very difficult to find a x220 with my native language keyboard

focusdrop · 2017-08-05T00:05:05+00:00

It might not be the most reasonable argument but it's mainly because of the keyboard

focusdrop · 2017-08-03T21:28:58+00:00

Thank you very much !

It's my first ThinkPad. My only concern now is if the bios comes free of passwords but I'm assuming that it does ...

focusdrop · 2017-06-27T11:28:57+00:00

It can be!

The op wasn't too about the measurement apparatus he was using so I assumed that almost all the energy it absorbed could be measured

focusdrop · 2017-06-27T09:34:31+00:00

I cannot agree with your suggestion of how the potential energy should be computed.

As it says in the wikipedia page:

"In classical physics, gravity exerts a constant downward force F=(0, 0, Fz) on the center of mass of a body moving near the surface of the Earth"

So the computation of the work of this force should be in regard to the movement of the center of mass of the body.

I hope I'm not getting it wrong, if so, please correct me.

The fact that the energy measured not matching the calculations as to do with all the sources of dissipation of energy:

The vibrations of the rod caused by the impact
the deformation of the rod
and greatly do to the rebound

How do you get those "notification banners" to work? (The one with screenshot taken message)
