Oh gosh, ink and powder, how cute. Our lab SEM/FIB heavily disagrees with your assessment. Even had luck with an interferometer without even trying... Even regions you deem difficult/impossible to find often show up clearly. We see them by accident if something was touched by someone who doesn't wear gloves, you think a state level actor won't find them when trying? That is assuming they don't just force your finger on the sensor...
Fingerprint sensors are dead easy to bypass though. Unless you wear gloves your phone's case contains the unlock information... So intelligence agencies will still get in easily. Bogus argument. Quite frankly there is no reason to encrypt the sensor data on a board level, the moment they had sufficient access to take a desoldering station to your phone it's already past the point of trustworthy. Then again they'd just force your finger on the sensor... And if you want a sneak attack, just bug the screen driver and capacitive touch IC instead... (easier and far more valuable data).
Ever looked at the uptime of other types of plants? Gas and coal is also pretty high maintenance. Comes with the terrain of pushing a few tens to hundreds of MW through a single metal shaft... Keep in mind Doel is 1000 MW electrical! The steam power before the turbine is far larger. If something goes wrong with the turbines or generators at those scales you slam the breaks? Imagine wat a few tons of steel turning at 50 rpm could cause if things go wrong with it. Transformers also blow up and catch fire all the time. These things are all normal for large scale power generation. Only reason wind doesn't have it is the relatively low power, so the stresses are lower. Stop following sensationalist media.
Additionally I can say duct/duck tape is heavily overrated, for most applications I found Kapton tape to be the prime choice. Fire proof, good insulator, usually comes with an adhesive that doesn't leave too much residue, and extremely strong. Only thing speaking against Kapton tape is that once it starts tearing it'll go through completely. Additionally the entire electronics industry runs off this stuff; it's one of those consumables you have in every manufacturing plant that you can't quite explain. But the day it's no longer there everything will stop working most likely.
And his prequels were quite frankly terrible. The Phantom Menace I could sort of live with, Attack of the Clones was ok in a few ways but was mostly still a miss. But lets not act as if his final attempt (Revenge of the Sith) was worth anything, it made everything look like a bunch of toys and was a worst case abuse of CGI. And lets not forget that piece of rubble falling on Obi there, that was the least convincing special effect I've seen in ages. The fact that that made it into the movie alone was already quite saddening. Not to mention Anakin turning went essentially from "No, I won't listen to you" to "Yes, Master" in a single line. And much much more... For that I'm happy Disney bought it, at least Disney will prevent such crap from ever making it out of the writers room.
That's the dumbest thing I read today. And that includes a transcript of a Trump interview. You'd end up blocking loads of legal content using such filter rules...
You might want to look into the machines LPKF is selling these days. Additionally two days is slow, we've gone from initial design to finished device in less than 8 hours at work. I should probably point out that's with some help of a LDI system and the fact we're running our own in-house prototyping lines. Most high-end board houses can also do same day delivery if the laminate isn't too complex and you're willing to dish out the money for it. (Be prepared to cough up a couple of thousand euro for a single set of boards if you do that.)
Please line up with the folks who want convoluted security systems that break constantly and don't actually work when you're on the move. In the meanwhile I'll try to get some work done.
Oh dear, you have much to learn about how to get computers to actually work without convoluted setups that break constantly. There is a fine line between usability and going far over the top in security. I'm exposed to both systems, the one at my desktop at work you only need to SSH tunnel to your computer. This is fine 90% of the cases, though many times that's already near impossible on hotel internet due to extensive blocking of "non-standard" things. The other system I'm commonly exposed to runs several levels of firewalls and requires a VPN client on top of that, it's a nightmare to login to and requires all sorts of specific browser plugins that only work on MSIE, not to mention using it through hotel internet is a no-go. And anyway, if you aren't prepared to leave a service open to the world you probably shouldn't be running it in the first place. Additionally ever tried interfacing to lab instruments over a network filled with firewalls? I can tell you right now simplicity is often a better choice in the long run.
Yes, many advantages to a unique IP for your machine. Especially if you're running terminal services. Even if you're going through an SSH tunnel (and you should) it still prevents many issues. And you can also bind a hostname easily then, which is somewhat more difficult with NAT around.
Screen printed silver is the main conductor for cheap printed electronics... Two barely trained operators with a small machine can run a batch of a few hundred thousand pieces within a week with screen/stencil printing equipment. So a bucket of silver paste, some plastic sheets, and a moderately clean space will do. In the meanwhile copper might look cheaper at first glance, but you need to consider the processing cost as well. When considering a single sided circuit with the same volume you'll need at least a few you need hundred square meters of photoresist, large quantities of obnoxious chemicals (degrease, developer, etchant, stripper, plating solutions or OSP), way more space for the lines (degrease, roll laminate photoresist, illuminate, remove protective foil, develop, etch, strip, OSP immersion/spray or plating), not to mention the cost of the water treatment plant assuming you're not running it in China where you can just dump it into the river I suppose. For assembly the circuit boards still have an advantage: solder paste is a lot more forgiving than conductive adhesives. Needless to say, PCBs are well on their way out for certain applications! Obviously copper still has a few major advantages, it's a great heatsink, mechanically more forgiving, able to carry great currents easily, and is very easy to assemble components on. But think about medium volume RFID, keyboards, signs, etc. and you'll usually end up with screen printed silver paste as most economical solution for medium to lower-end high volume manufacturing. For extremely high volumes you could consider aluminium as conductor in more than a few cases, but lets not get into those pesky details!
Not to mention a toddler could design a better UI than the GIMP team... For being graphics editing software it sure could use a touch of a graphics designer in that department. Then again it is a GNU related project I suppose, which goes a long way explaining why its a piece of condensed misery that doesn't support things the competitors have for 10+ years.
Actually a lot of software is windows only if you want it to truly work. I'm a heavy user of CAD software (electronics mixed with mechanics), I need cisco VPN and Citrix to work together smoothly, and our toolchains consist out of programs written (badly) by vendors who often have no competition at all. So support is non-existent to sum it up shortly. Then you have artwork conversion for manufacturing which is a nightmare in its own right. ( Not to mention some equipment still runs NT 4 which can be very picky about file systems.) Migrating to Windows 10 would be a nightmare, but Linux would be impossible. And even if I could get it to work in WINE the graphics support in Linux is so sketchy that the performance would make it useless. I can already get a Windows server on its knees with AutoCAD and Altium, what do you think would happen if I were to run it through WINE? And I hardly think I'm a lonely case. Additionally the hardware compatibility beyond Windows 7 and in Linux is a disaster, Imagine accessing a GBIP bus or PLC card on Windows 10 or in Linux. The humorous statement "the computer says no" comes to mind.
The issue with considering > GHz radiation's effects are the dielectric parameters of the human body... You'd have to stick your head against the WiFi router for any measurable signal to penetrate deep enough to cause the described effects, or to be more correct the WiFi antenna would have to pierce your skull. But the moment we start using WiFi antennas as crossbow bolts we have other issues arising I fear. But the FM band is favourable because the corrected half wavelength is about the length of a human; Additionally the dielectric parameters in this frequency range are far more favourable combined with multi-kW transmitted power vs. mW.
Yeah, because the 3G bands in terms of wavelengths are completely unrelated to human body dimensions and absorption peaks of common chemicals in the human body. (Hence my statement that it was stupid to use 3G as example.) If anything I'd say the FM radio has the most chance of causing harm, the wavelength is in the right spot vs. the average human's length and limb size. Anyway consider the transmitted power vs. absorption/dielectric properties vs. energy required for biochemical reactions to take place and you'll realise how idiotic this entire concept is. I'm going to agree sitting next to a high power transmitter is a very bad idea, but a WiFi router isn't going to kill you in any reasonable frequency band with the transmitted power it has.
The nervous breakdown is mostly due to the stupidity of bosses and team leaders. Get rid of middle management and you solve that issue. Also the general dislike towards people comes from things like "can you fix my lapyop". I wish it'd be legal to pull out the spinal column of who says that. Additionally we only terrorise social sciences majors by finding loopholes in their silly pseudoscience theories.
But on the other hand this article makes a fatal assumption. Engineers in Africa and the Middle-East are a very different demographic compared to western countries. Additionally of the ones I've worked together with I'd say about 70% of them are grossly incompetent vs. their western counterparts. The educational system there is becoming better in recent years but they have a long way to go. And indeed many of them are hyper religious, while in our group of 50+ engineers at work there are maybe 5 people religious; and only one seriously who happens to be Egyptian. Their mindset is also very different: they think engineers should be at the utmost top of society and think people should have endless respect for them. Needless to say such a group has a tendency to be quite susceptible to terrorist recruiters. Luckily for us I'm fairly certain 99% of them wouldn't be capable of manufacturing high explosives without blowing themselves up in the process.
RAM is cheap these days. 8 GB will get you far, but 16 GB makes 100 not so big of an issue. And it still responds quite fast at that point, even with all the javascript abuse these days...
Try double sided tape, I've managed to stick pieces of Teflon together with some of those for test setups. But for acetal sheets if you really *must* glue first use 250 - 300 grit abrasive cloth and then an epoxy based glue.
Math comes in when the going gets tough. For example, you have a big pile of data and you need to extract data from it and do operations on that part and write it back. I had this issue a few months ago. Initial runtime was more than 20 minutes; and that's when you pull out the data processing sledge hammer, Fortran. But even then you need to know what you're doing. The end result is 0.4 seconds. Required a lot of mathematical understanding of what I was trying to achieve, and a good background in system and CPU architecture to find bottlenecks. When is it safe to split up a step in atomic operations, which operations should I avoid, how much accuracy am I willing to sacrifice,... ? All these things require a good understanding of math. Additionally is your algorithm stable, or will you get oscillations after the filter? These things all require a good grasp of math and systems theory. Yet these idiots claim none of it is necessary...

So you take your phone out of your pockets without using your inner hand surface or finger tips. Interesting...
Just pick it up once and most of your hand is on it... Maybe back of your hand *might* be an option. But still silly looking.
