Tom1971··on Used GPUs flood the market as Ethereum's price drops below $150
The theory out there is that the 480 has lower performance due to TLB trashing. So it's not DRAM size specific but GPU architecture specific.
Tom1971··on Caffe2 adds 16 bit floating point training support on the NVIDIA Volta platform
Your table doesn't include the new "tensor core" TFLOPS of V100.

That's a core that does 4x4 FP16 matrix multiplication + 4x4 FP32 accumulation in one go.

That's where V100 gets its boost, up to 120 TFLOPS.

And if that's too much, there are boards like this: https://www.amazon.com/RioRand-EP2C5T144-Altera-Cyclone-Deve...

Together with a $10 USB dongle, you can get going for $35.

It's still big enough to store small CPUs etc. A lot of fun!

Digikey is a terrible price indicator though.

A good first order estimate for FPGAs is a factor of 10 between digikey pricing and volume price.

My wife's manager at big tech company used to get an email whenever she inserted a USB stick.
Tom1971··on AMD Zen and Ryzen 7 Review: A Deep Dive
I don't think spending time and effort to optimize code for Ryzen will be time well spent.

Would you do it if you had the choice between that or adding new money making features/fixing bugs?

Tom1971··on Nvidia GeForce GTX 1080 Ti
A 1080Ti with 352 pins at 11Gbps has almost the same BW (484GBps) than a Vega with 2048 pins running at 2Gbps (512GBps).
Tom1971··on LG 5K display must be kept at least 2 meters away from Wi-Fi routers
I went from 2 1440p to one 32" 4K and 1 1440p.

It's been one of the biggest productivity improvements since moving from 640x480 to 1024x768.

The 1440p is now only used for minor stuff like email and not really necessary anymore.

I soon moved to a 32" 4K at home as well, because I just couldn't stand just 1440 anymore.

One of the interesting parts is that I don't use 4K fully: it's too much surface are and your head tilts too much to see everything at once. But what's great is that I can put a background process as full screen in the background and have a 3500x1800 window in front in which I do my real work. So I can observe the proceedings of the background talks without having to toggle windows all the time.

In my worgroup of 7 engineers in your successful high-tech company, there's on employee younger than 40.
Tom1971··on 2016 Retina MacBook Pro Caveats
I tried that at the Apple Store.

It's an option.

But there are so many programs that require ESC, so it's only a half-way solution.

Tom1971··on 2016 Retina MacBook Pro Caveats
Yes, the old Apollo HP workstations (on which I initially learned vi before it became vim), ESC close to the left shift. Very convenient.
Tom1971··on 2016 Retina MacBook Pro Caveats
Work: a metric ton of #defines that are generated by our hardware register addressmap generator, as well as a very particular file naming convention, which has a heavy mix of uppercase.
Tom1971··on 2016 Retina MacBook Pro Caveats
While, over time, a lot of today's annoyances with the new Macabook's will fade away, the lack of ESC key is a deal breaker for me.

I tried it at the Apple Store and it's pretty much unusable. (It had the seen issue as the writer, apparently relying on the physical click to know whether or not I had pressed it. In addition, I also mistyped it a lot. Maybe hack to replace the whole touch bar as one single ESC key will do it...)

I've been told to remap the ESC to CAPS LOCK to vim usage, but I seem to be one of a rare breed who uses the latter the way it was intended to be, so that's a no go for me.

Tom1971··on Software Developers: how to get a raise without changing jobs
In a large HR department, chances are you're dealing with somebody for whom you're just a number instead of somebody has a personal grudge.

Nothing personal, just business is the attitude you want when handling something as trivial as a salary negotiation.

Tom1971··on Software Developers: how to get a raise without changing jobs
That's a rather narrow minded way to thinking about the issue.

I've accepted a counter offer twice, and both times I was glad that I did.

There could be many other reasons for a company not paying what you can get somewhere else. A very trivial one is the yearly update cycle: that may happen in January whereas you get an offer in June. Companies that hire don't align to the schedule of your current one.

And hiring companies inherently know asking somebody to quit and somewhere else carries a risk that needs some amount of kind of reward.

Hell, how can one personally even know what he/she is worth? There are so many factors at play. It'd be narrow minded to expect pricing perfection on something nobody really can get right.

Tom1971··on Microsoft Shares Soar to Record on Earnings Boost From Cloud
They buy back stock all the time.

Just a few weeks ago they announced a $40B stock buy back program.

Tom1971··on [dead]
Yes. And far more than hanging chads, that election was primarily decided by thousands of potential voters being incorrectly purged from the voting lists.
Tom1971··on [dead]
Depends what you mean by electoral fraud. In the US, the only electoral fraud that has a significant impact is one where groups of voters are prohibited/prevented from voting. Pennsylvania is particularly vulnerable to that one due to very broad rules that allow people to question the legality of other people to vote. It's why Trump has been calling PA supports to do exactly that.

Other types of fraud (ballot stuffing, voting multiple times, voting when you're not allowed to etc.) are exceedingly rare, and it would have to happen at a massive scale for it to make an actual impact.

That's just not going to happen, especially with it being a felony.

Tom1971··on OpenAI is Using Reddit to Teach An Artificial Intelligence How to Speak
Gimping, in this case, is actually: adding hardware, that costs quite a bit of silicon area, on one chip that will probably never be sold as a consumer GPU.

I don't see the issue with a company making a very high-end product, adding stuff that doesn't have good use for consumers, and asking extra money for their effort.

AMD doesn't have double speed FP16 on its current FPUs either. The latest version has FP16 at the same speed as FP32, but if you're doing that you might as well use FP32 always.

And let's not forget: the Nvidia consumer GPU have deep learning quad int8 operations enabled at all time. They didn't need to do that and could have reserved it for their Tesla product line only.

Tom1971··on Show HN: InstaPart – Build circuit boards faster with instant parts
At the very least, you should have allowed new users to change the screen name first, and inform them of this.

I assume you want commercial users to use your service as an alternative for DigiKey etc. Some prefer to stay under the radar in everything they do.

Second remark: for all components that I select, the 2D view shows:

   Th
   P
The rest falls off the screen on an iPhone 6. I'm guessing it wants to say "this part is not available" or something.

You need to test drive your website on more browsers.

I just created an account with the LinkedIn login option.

When I get back to the front page, it shows for everybody to see with my full name that I just joined snapeda.

Why???
