TIFF is only huge because people put huge files in it. If I want to save a off a nice huge lossless image I will save it as a 16bpc LZW TIFF. Often this image is around 130 megapixels but may be closer to 40 megapixels (down sampled to this) if it is going out for printing. The largest image I have dealt with was up around.5 gigapixels and those all required lots of individual shots taken with a repeatable setup in very good conditions for it and a bunch of computational power to create. That was more of a could I do it experiment but I now have a nice image that if I really wanted to I could have as a mural and you could stand right up to it and it would look good.
I think the parent poster wanted to say bits per channel not bits per pixel. 32bits per pixel is 8 bits per channel (R G B) with an 8 bit alpha channel, and 16bpc would give you 48bpp (RGB) or 64bpp(RGBA). Tiff will do 32 bits per channel or 96 bits per pixel (no alpha channel) or 128bits per pixel with an alpha channel.

You probably mean taglish. While a joke it wasn't meant to be taken as a slight against them as just about everyone in Manila I have met speaks that mix of Tagalog and English and you hear it on the radio and TV as well.
I am always interested in what people are doing and how things work for them as eventually I will have an off grid system when I get a cabin built as I don't want to pay to have a line run and for a transformer or have to run, maintain, and fuel a generator. I would be curious to hear how the AGMs hold up under use over the years as for the current application I have for them I haven't seen a good use-case to justify the additional cost (trolling motor battery) so instead just got a larger regular deep cycle battery.
Says the imbecile who is not aware of how security works. Just ask the Iranians about how not connecting ICS systems to the internet worked. Yes there are plenty of dumb managers out there who would want to connect these systems to the corporate network (and thus the internet) to save a buck but then there are methods of attack that can work around even an air gapped one. The people who are actively targeting these systems are not just your run of the mill script kiddies, or computer crime orgs, but often are nation states. That is why orgs like NERC have patching requirements for systems even though those systems aren't suppose to be connected to the internet. Layer upon layer of security, so you know if Bill the janitor finds a USB stick conveniently left on the floor near by and then tries to plug it into a server it won't cause issues, or Bill instead is just a bad actor.
I got an offer like that once for a job out on the east coast for a senior position with all sorts of specialized knowledge. I laughed at the recruiter and they asked if that was a good offer. My response was that it was a fucking terrible offer as I make over 3x that now and live in an area with 1/2 the cost of living.
1MWh is is huge battery I've only heard of those being used for grid level storage. Even for a large a 19KWh (48 volts @ 300Ah) storage system you would be looking at about $15,000 which should be a few days if one isn't dumb about usage. That assumes that you didn't build in any additional redundancy into your generation capacity like a couple of those small 700W windmills that aren't that expensive.
Serious question what kind of batteries did you use for your solar install. The Tesla batteries which had a bunch of hype and were pushed as being ultra cheap looked to cost the same as the really old Nickle-Iron batteries. Both of which look to do better than deep cycle lead acid on a cost per watt hour. If you used lead acid there isn't much that can be done to increase capacity or decrease costs, especially since those have fairly short lifetimes so effort has gone into increasing those but that adds costs. At this point I would still probably choose Nickle-Iron over lithium ion batteries because of the longevity of Nickle-Iron cells and how they stand up to abuse and neglect.
The utter best you can hope for out of ICE is 50%, which is theoretical, not economically viable.
Actually it looks like the actual best for a real production engine is about 54% and that is for the MAN S80ME-C7 diesel marine engine which is being built and sold now. Those large slow marine/stationary diesels are very efficient. Only combine gas turbines are more efficient but there you need to have something to use the waste heat to get up to their claims of over 60% efficiency if not they fall below the efficiency of most larger (think train, haul truck, office building backup generator) diesels.
Yes the US GPS system is under control of the US military, but they would likely never turn it off as they are highly dependent on it. They will however turn on selective availability but even that is something that can be worked around with not too much difficulty. If one has the ability to get data out of some CORS stations and some RTK software or one has access to a DGPS system you can get back to good levels of accuracy. Even without all that extra effort all of the other systems would still be available which most GPS newer receivers can also get. My phone, for example, has no problem getting data from US GPS, Galileo, or GLONASS satellites.
I'm willing to bet that if the entire GPS system (US GPS, EU Galileo, Russian GLONASS, and what ever the Chinese and Indian systems are) all go out we have bigger problems than just missing GPS. The systems all operate at similar frequencies, because they wanted to ensure that if someone tried to jam theirs it would also jam the attackers. So I would say if they all went down we either just experienced a massive CME and soon will have melted power lines and transformers, someone nuked them and the whole planet is going to have a really fucking bad few hundred years shortly, or we are going to be enslaved by aliens who just took them out. Much like the people who horde gold and say what if the US dollar collapses not realizing that the lack of regular currency will be among the least of their problems if things get that bad.
I got one of those surprise bills once. My city bills for water quarterly and one day Igot a $170 bill for water when normally it is in the $60-80 range. Turns out that the problem was the basement toilet's flapper valve had worn out and was leaking a bit and since no one really ever uses the damn thing it went unnoticed. That damn toilet used as much water as the rest of the house normally. A small continuous leak over a long time adds up to a lot of water. The next bills was back to normal. As a side bonus I figured out where all the water valves in the house were and what things didn't have them and probably should.
You would be surprised at the dumb shit I have seen in dealing with securing similar systems. Yes it is layer upon layer of security measures, or it should be. But far too often someone forgets about that ancient tape changer in storage room b-37 that is still connected, or some PHB decides that they want to be able to check in on machines and shut them down from their cellphone while at home.
One of the problems with ICS systems and others like them is that they assume that the operator knows what they are doing as most of the time the people who are running these things do. The problem occurs when someone who isn't competent, or is malicious wants to do something else. Here the system may warn them before but will let them do it anyway, unless it was a known bad configuration when initially programed but this often is far too big of a state space to program for. Yes there are mechanical limits put on the machine but that doesn't mean it isn't possible to create an unsafe set of settings as was done with the aurora generator test where it was brought out of phase with the rest of the grid. Under normal operation that would have been impossible but by toggling things correctly it became possible to bring it out of phase. This took a bunch of very smart people to figure out the right sequence of events so while it isn't something that could be done easily it could be and with cellphone apps becomes more likely. That said of all the things to worry about this is very low on the list, unless it is your job, and instead would worry more about squirrels.
Also you seem to have forgotten about the whole Stuxnet incident and other related and similar attacks. All of which were able to abuse equipment. Of course there was the attack against the Ukrainian power grid a little more than 2 years ago too. So I stand by my statement that very often this is overblown in the media who love spreading FUD, there is a nugget of truth hidden there and people who have to deal with these systems need to pay attention.
Not all of it is FUD but it is likely fairly overblown. Remember there was this from 10 years ago where INL let the smoke out of an expensive generator. There is a lot more to the test that was not released to the general public but to those in the industry but it isn't entirely FUD. It also isn't surprising that companies want phone apps to interface with the factory floor devices because that kind of stupid shiny sells to MBA types.
It was more in the 50s and 60s that made in Japan meant garbage. That started changing in the 70s when it meant inexpensive but good quality, and by the 80s made in japan was something to be looked for. Before WWII the Japanese did make high quality stuff but when your country is basically destroyed after a war and then occupied for 10 or so years it tends to be kind of shitty for a while as you rebuild and recover.
I am mostly familiar with this in regards to cameras and optics but I get the impression that most other Japanese industries were similar. While inexpensive at the time those Japanese SLRs from the really late 60s and 70s were really high quality being as good or better than others offered at the time. The lens quality that they produced was great for prime lenses back then which hasn't change much other than better coatings and some different low dispersion glass mixtures (no more thorium glass). Even the quality of work outsourced to them (series 1 Vivitars) which while not Japanese designed are basically as good as can be found now. I still use old Super Takumars (single coating, no thorium glass) from the 60s, SMC Takumars (multicoated optics and some have that wonderful thorium glass) from the 70s, and a Series 1 Vivitar from the 70s (if you don't know what these are and are into photography use one and see just how good vintage glass can be) on modern cameras. For those who pixel peep they are as good, when operated competently, as modern high end lenses and will curb stomp modern non-high end lenses. To be fair modern zooms are almost always better as are ultra wide angles that the old ones as they benefited greatly by the additional computational power that could be thrown at their design although there are some good older zooms from the 80s that while a bit slow are still pretty damn nice.
Well that may be because Hungarian and English are both odd languages. Hungarian because it is off doing its own thing and English because it is the bastard child of multiple invasion forces over several millenniums. Learning a language that (from what others above said) is basically a modern invented romance language would provide at least some basic jumping off point of common knowledge for a Hungarian speaker when learning English. Menj menj magyarul!
As someone who is making a concerted effort to learn Hungarian it really is a difficult language to learn even if you do have a native speaker to work with as it is so different from English. As an added bonus I can carry on a simple conversation with my wife's mother and grandmother and she can't understand.
I would say it would be best done as unsupervised clustering tied into a GIS system. I have written my local reps at my state house and state senate about it several times but they never want to hear it because it takes away their power to help ensure they have a safe seat.
Basically my proposal has been:
1. Initially all districts are centered at their current representative's house. If there are fewer seats this time then last then district centers are removed randomly until the correct number is reached. If there are more seats this time then last then district centers are added randomly until the correct number is reached.
2. The district with the lowest population picks first.
3. Areas (houses, town homes, apartments, etc) are added to a district such that the closet one available to the center added first. If there are 2 equal distance then preference is given for the ones that are on the same side of the road, in the same town, then in the same county. If neither of those are better satisfied then pick one at random and add it to the district.
4. Repeat steps 2&3 until all areas have been chosen.
5. Calculate the new center of each district.
6. If the new center of any district has changed areas from where it was in step 5 of the previous run (step 1 if this is the first run) then save the new centers and clear out the districts assigned to each district and start at step 2.
7. if the new centers of all districts have not changed areas from where it was previously this is your new district map.
I am sure that there are a few more tweaks that are need to ensure that each district has the same (I believe MN law is +/- 1) number of people in it but this seems like a much more reasonable solution instead of the bickering that happens every 10 years. As an added bonus this requires writing the program once and then every 10 years drop it on a computer (really any somewhat modern desktop would be able to do this) and let it run for a bit. You no longer need to pay for the old human process and likely would get result much quicker.
With symmetric key crypto you would need a much bigger quantum computer than that and even there it only makes AES-256 on a quantum computer as difficult to solve as AES-128 currently is on a classical computer. Or to put it another way, it would still require more energy than is consumed by the US over several years.
