The brain is more like a CPU implemented in FPGA than a CPU synthesised into silicon. Signals are only somewhat local - you get increased activity in this or that region and can correlate it with what happens in the brain - like power analy

What? No. The signature needs to be added by the image sensor as it gathers data. It shouldn't be easy to extract it and that's it. It's even less difficult than keeping the DVD/Blueray keys secure because each device ha

Did YOU even check what you cite? The AUTHORS of the original paper got a dataset from a company. They didn't assume the fraud from the start and published the paper based on it. Later, when they tried to analyze the issue more in-dept

Anything that you access using thunderbird with GPG configured? It gives no worse privacy guarantees than protonmail and possibly way better - because if you use protonmail through a web client and they get a court order to serve you a &quo

Every camera will have a unique key so a single key leaked is still no issue. It's easy to maintain a blacklist - similarly how CRLs work.

I think the solution can be reached following from a set of simple observations about a single line of sight: - in a square room all angles are right - with wall at right angles the laser light will always create an inscribed square and ret

From what happened to me - cards die, especially older ones when there is a lot of data written to them even without power failures (UPS ensured that). And when you have a journaled filesystem there is a lot of writes. I made hybrid systems

Not really. If police is corrupt and want someone to disappear they just won't create arrest records. US police was using black-sites where people disappeared without problem. On the other hand public arrest record put a great opportun

Banks, having surplus cash, offer low-monthly-payment loans which allows more people to buy them, by the way earning 0.6-0.8 * X to the banks. Since there is a lot of cheap credit price stops constraining the demand side. You can get almost

So far in in most of the world even platter disks (which have really poor performance with modern Windows) are faster than network. Which means you can download description of the difference and reorder the file locally much faster than dow

There is no such mechanism in TLS, but HTTP Range header and wikipedia supports it. So if you want to be protected agains this side-channel problem you can use Connection: Keep-Alive header along with Range header to split each request into

Anything that is in web browser (like e.g most uses of protonmail) offloads all security to the security of the TLS connection. Unless you also ensure proper certificate pining, if someone can get a court order for any accepted CA to give t

But those numbers without context are just that - numbers. It's the context that makes it information. GPS coordinates by itself are the same, they're just numbers, but by attaching meaning to them you may make them dangerous or i

"95601890" is just an arbitrary number, the same as any other. Additional metadata, such as "it's a driver's license number", "it relates to person X" gives it context and makes it information. 4037 i

If you're the only person that knows a particular sequence of letters or numbers you own it. If you remove all knowledge of that information you destroy it. And by "all knowledge" I mean every known way to generate it, not ju

Punching holes doesn't work only when network devices in between are broken or are actively preventing it. From the network point of view it looks the same as two hosts starting an outgoing TCP connection through nat - if that works th

If you're talking about assembly then every single statement in python will involve hidden conditions. I was talking about the idea behind the code - that map is a pythonic shorthand for a bunch of if-then statements, it still expresse

In Poland I can get a board or 3 in a week but it will be expensive (about $150-$200 for a small one), normal, cheap delivery time is about 3 weeks. China is even cheaper but takes 4-8 weeks. That's why I made a lot of boards myself as

But there is conditional logic "hidden" in lambda mapping. You want it without ANY conditional logic try this (python3): [str(n)*(n%3!=0)*(n%5!=0) + 'Fizz'*(n%3==0) + 'Buzz'*(n%5==0) for n in range(1,101)]

I don't believe "quantum computing" will get us any step closer to breaking RSA. Similar how complex number theory didn't allow us to draw a square with area of -1. To break RSA-N you need a superposition of all the numb

They don't. You have to rivet vias which, while relatively fast when compared to soldering them, is pretty expensive (~$20/100).

Ordering from china is inexpensive but it takes time. I can send a pdf to a local printing house in the evening, get the negatives around the noon while the PCB is drilled. Then etch and mask it in about 2 hours and solder all the vias in n

You can make a CNC router pretty easily with an arduino, cnc shield and either furniture boards or aluminium profiles. You you can also make a simple probe for autoleveling and mill the pcb too, but imo it takes too much time. Etching has w

For an average SSD - no. It's pretty much multiple times faster than other options.

I just played a bit with CNC engraving and laser projection, so don't have that extensive knowledge, but AFAIK: Even with your example of 10W, 10mm beam it has a bit more than 0.12 W/mm^2. Hundred times the power output from the s

With a proper lens I think it just might work. You need to get huge focal length to make those pixels work. Then you need illumination because with those focal length it will be really dim. Then you need to scan the area because your FOV is
