Here's an article (not written by me, just found by using google) that has an example how the VHDL/Verilog compiler infers to use a dual-ported SRAM from code that describes the behavior, including the bugs you'll encounter.

Especially “note the soccer pitch for scale”, which has not been drawn to scale, it's blown up by a considerable margin! That machine is HUGE! UPDATE/EDIT: The "socker pitch for scale" might be the 2 pixel wide small dot

You can have arbitrary indices being created by arbitrary users. The database(s) that is(are) used by the locate command can be specified by command-line option or by an environment variable.

That's certainly true. But also (from a investigation point of view) more suspicious than a filesystem covering the whole harddisk, but only filled to 20%. That will always be a problem, as long as the "visible" filesystem just maps block 1

You could measure a lot of things when messing with power lines, but ultimately someone has to be responsible that circus that are powered of or safe for any reason stay safe. You measurements cannot give that guarantee, but installations h

Yes, that's for sure the smartest way to deal with it, if you have such a specific requirement. New filesystems (zfs, btrfs) with their sub-volumes also make that much easier, because they can dispose of subvolumes, and recreate them very

I abhor deep indents, and when I have deeply nested loops that just serve to trivially enumerate things, in C I sometimes add a helper function for the iteration. e.g. instead of: for(int i=0;i<N;i++){ for(int j=0;j<K;

Depending on the cards and their configuration, you could generate the key outside (say, on a trusted machine at home) and upload it to the card. If the cards gets stolen, and you trust the security of the card to not leak the key, you coul

You can certainly ignore both limits in your homemade-receivers, but if you ever want to ride faster than 1900km/h you will have to account for an increased doppler shift (I hope I'll not help any terrorists by explaining that ;-) ), and ev

I have to join in to say that this page (which exists since some time, only has recently be updated) is really impressive, and a very good educational material for everyone wanting to really understand the workings of GPS. Nevertheless it's

I think truck drivers are more or less trained to ignore everything but the last-resort sign. Near where I live, there's a small bridge (railroad on top, road crosses below) with not enough height. It has some limit on vehicle height that i

Yes, you are absolutely right. But I think this is not the main point of the article. The main point is that in a huge corporation with rules for purchasing and choosing suppliers, there's an insane amount of labor spent in administration e

But as far as I have read the article the glitch is not about the simulation of cards but rather about game mode flags you can carry unintendedly between different game modes. The quoted example makes him pause game one at a high win, switc

I've read a little bit of the material, but I don't get the feeling that they looked beyond block-level RAID5/6 (which btrfs/raid5, as far as I understand, is not). [1] mentions that RAID5 never checks parity on read, which is not an issue

But of course "access to a repeater" violates the part of "with no centralized infrastructure to fail" in the parent's post. But one also has to distinguish old-school repeaters covering a medium-diameter area from the worldwide, internet-c

Dialing is "out of band" everywhere except analog phones, and dialtones are just the reverse channel giving feedback to the user (just because there's only audio information, a "single band"). The TL;DR of the article probably is: The inve

I think Python is an excellent choice for people transfering their know-how from other platforms (e.g. Linux) to Windows. The win32* libraries (as installed on a stock ActivePython .msi install) allow you to automate a lot of the windows pl

It's more readable with openssl rsa -inform DER -in Ivy_Bridge_018s/Keys/FW/.priKey -text But still, I don't know how to verify that this key is not the one refered to by the "DO NOT USE" certs (which, to me, sounds pretty reasonable to a

Yes, but you'd expect the key (Keys/FW/.priKey) to be accompanied by some useful metadata (naming the entity the key belongs to, and a certificate from microsoft validating the key) to be added to the firmware image, wouldn't you? And if th

The single most useful thing to address perceived performance problems: Measure your performance. A often neglected part of the "list, rank, iterate" cycle is generating performance indicators that can be quantitatively assessed.

/me too/ I like it (tar|nc) as a quick alternative when moving data to or from low performance devices such as Android phones. Rsync/SSH really burns a lot of power for encryption. Makes a full x GB Backup much faster to pipe it through net
