If I'm understanding the article correctly, the hackers are using a easily reversed cypher for storing configuration data for their malware, which was reversed by assuming the presence of the string "C:\Windows\System". In th

The DEA could hypothetically ask the treasury to reprint a note with a particular serial number, given enough time. So random selection is an important property.

I think this would be a good starting point for what you are trying to achieve: https://libsodium.gitbook.io/doc/public-key_cryptography/aut... The first example shows both sides of the communication. The public k

Another option would be to use colour correction gels like from Rosco. They publish transmission curves for their gels: https://emea.rosco.com/en/products/filters/r3220-double-blue... (click on the little i).

That's a point, I was assuming low impedance output stages as would be standard for any ordinary hifi equipment these days (but not necessarily for the really expensive stuff of course...). Some of the expensive cables are over-dimensi

At audio frequencies (and well beyond), you won't be able to measure any meaningful differences: https://www.lifewire.com/speaker-cables-make-a-difference-31... And the absurdity becomes much more obvious when contrast

That only shows differences in white balance and tone. It can't give you any information about the CRI since you only have 3 channels of colour sensors in your camera. If you use a colour swatch palette that would be different.

Has anyone seen a description of the "misconfiguration"? It appears that both iOS (is) and Android (will) ship mitigations which disable the existing keys, but I can't find a description of the actual issue.

You can measure all the differences in TV picture you described (and you didn't even mention colour gamut & dynamic range). You can measure the differences in optical glass. You can't measure the difference between a $10&#x2F

I'm assuming safer loadable modules (there's no memory protection on most mcus) and choice of languages that have wasm backends. In some circumstances being able to run the same code in a browser in a test environment as on the de

I was wondering if it would be suitable for micro controllers (with let's say a few hundred kB of memory, not MB). I can't immediately find the answer but there appears to be a port to Zephyr OS in the repo so that is promising. T

Have you tried it the other way round... set the alarm those 30m later but if you wake up earlier, just get up?

That's an overly rosy comparison of money transfer fees. To make it a little more fair, it makes sense to compare against a competitive money transfer service rather than typical bank fees... For example transferwise offer transferring

Two things: - When you do actual product design, a lot of it is basically copy&paste from example circuits in data sheets. Over time you learn to recognise common patterns. The "trick for young players" though is that often th

I doubt there's much market demand for 1000 quantity bottles of Ibuprofen in Germany. If you need daily pain killers I would expect the insurance to pay for (most of) them.

Well.. Walmart is a large chain of supermarkets in China, and Costco operate there too, so they're not entirely irrelevant ( http://www.wal-martchina.com/english/walmart/index.htm ). Fortunately China has like

I would argue that with the extremely low cost of PCB manufacturing (and... if you have access to it... assembly) it's easier now to just lay out a PCB and get it made. The trick is to build up a library of circuit "modules"

A more developer-friendly language like Swift would give you an ArraySlice type with performant views on arrays, and developer-friendly syntax.

by janekm 8y ago
Python supports slice[-1] for the last element... Pretty reasonable. Also slice[0:-1] etc. Swift also has a lot of array slice sugar, like array.last, array.endIndex, array.removeLast ... Obviously there is a trade-off to adding a lot of su

I like the idea, and am certainly going to keep it on my reading list. I would really appreciate some indication of the strength of the evidence in a paper though... Some combination of the quality of the methodology, statistical relevance

What compiler does that? None of the ones I tried on god bolt seem to (after fixing the missing type on the function parameter)? And what's the undefined behaviour here?

Of course currently only TI can make these (though no doubt everyone else is going to make a real effort to replicate). The chip in question is rather pricey though, $11.44 in thousand quantities vs. $3.54 for the very similar NRF52840 + ab
