Why do some militaries use LCD or plasma displays on aircraft?

LCDs suffer badly from effects of humidity or altitude changes, lose pixels often, have low service lifetimes, limited view angles, have resolution problems and a far greater latency rate compared to traditional CRT...

I'm specifically interested in why LCDs are used on aircraft such as the AWACS, which don't care as much about weight or power generation, and more reliable lower latency CRTs might make more sense

Ah, my first LCD monitor, 2004. Running on a second computer that I used to host our teamspeak channel. I had a screenshot of the map and strat for the upcoming match. I could also move people between the offense/defense channels on TS.

The LCD monitor is still being used on our server, and it works fucking fine.

Interestingly, I'm still using both of those keyboards, and the MX300 (the right) mouse. The HP was my first USB keyboard and was $8.

The other mouse is the Logitech MX500, which I wore out. I've since (in like 2008) replaced it with a MX518 optical mouse. I had a laser mouse in between, but that thing was shit. Twitchy as all fuck.

The man he had said bet with talking about the vagueness and contrarian nature of Hawking's bet and statement regarding the loss of that bet has nothing to do with your dumbass re-interpretation despite this is what we've been discussing? That's some impressive mental gymnastics on your behalf.

>proper interpretation

Oh wow... The last time I heard that unironically, it was from a Christian fundamentalist that was saying the Bible provided justification for "killing faggots." Interesting that you and him seem cut from the same cloth.

>Jesus, how long did it take you to find all that unrelated anecdote just to make yourself look less stupid?

About 5 minutes.

I'm fascinated by alternative protein/meats. I'm no vegetarian but with future water shortfalls, less grazing land and a wealthier global population wanting to buy meat.

First up is the Beyond Meat company: http://www.outsideonline.com/outdoor-adventure/culinary/Replacing-Meat-Plant-Based-Meats-Vegetarian.html

Brown’s first breakthrough came when he discovered Fu-Hung Hsieh, a food scientist at the University of Missouri who had perfected a way to turn soy protein into strips that chewed like chicken. (Top secret, can’t tell you, but it has to do with heat, kneading, and cool water.) Brown founded Beyond Meat in 2009, and in 2012, its inaugural product, Beyond Chicken Strips, began wowing the gatekeepers of the food world.

“Most impressive,” said Food Network geek Alton Brown. “It’s more like meat than anything I’ve ever seen that wasn’t meat.”

“Fooled me badly,” Mark Bittman admitted in his New York Times food column. It also fooled Twitter cofounder (and vegan) Biz Stone, so he invested in the company.

So did Bill Gates, whose Gates Foundation backs potentially world-saving innovations. “I tasted Beyond Meat’s chicken alternative,” he wrote online, “and honestly couldn’t tell it from real chicken.” Gates quickly realized the blockbuster potential. “Our approach to food hasn’t changed much over the last 100 years. It’s ripe for reinvention. We’re just at the beginning of enormous innovation.”

Alright, so my POS laptop that I've been nursing along for two years now has decided that it doesn't want to work charge unless I'm physically holding the cord at just the right angle, with just the right force. Which kinda precludes all two-handed activities like gaming and typing, and frankly, even browsing the internet is a pain in the ass when I have to deathgrip the computer to make it work.

Time for a new one, although I really didn't want to spend the money on one right now.

Yes, I know it's cheaper to build a new one, but not by much, and I don't have the know-how to do it, so unless someone in PDX wants to help out with that, I'm stuck buying one from a box store.

I have one damn standard for a new computer: It has to run STALKER. Well, and Supreme Commander, but that doesn't have the hardware requirements that STALKER does. So I've been looking up technical specs on the cheap desktops ~$500-$700 at Best Buy, and none of them come near the 4.2 gigahertz processor that STALKER wants, but some of them have quad-core processors.

I haven't worked with a computer's guts since 2001, so I've missed a few things. Would something like this work?: http://www.bestbuy.com/site/hp-pavilion-desktop-8gb-memory-2tb-hard-drive-black/5814032.p?id=1219194065876&skuId=5814032

I'll pick up monitors off craigslist or from a pawn shop or something, but I don't want to deal with another second-hand computer. This one was new, but a lemon, and I would LOOOOOVE to have the warranty, but don't. C'est la vie, and I try to learn from my mistakes.

It's not the physical aspects of putting parts together that bothered me, it was the technical aspects of compatability and software. Which is apparently quite easy, according to the various posters in this thread.

That said, since >>7163 I've totalled a car and bought a semi-beater SUV that's a rolling project (I can drive it daily, and do my own work, but it does need work), and moved. My rig was full on the move here, so until I'm trailer-born, I'm very, very tight on the total volume of possessions I can have with me.

I don't mean to shit on your advice or anything, and I'm thankful for it, but a computer is just not on my priorities list right now. I'm going to consider this thread closed.

>the bug behaves like a regular virus from the outside: infecting the device, operating undetected, and coordinating actions through a peer-to-peer network. But instead of performing DDoS attacks or looking for sensitive data, Wifatch's main role seems to be keeping other viruses out. It stays up to date on virus definitions through its peer-to-peer network, deletes any malware discovered, and cuts off other channels malware would typically use to attack the router.
>(...)the virus seems to make little effort to conceal itself, and leaves various benign messages in its code. One, triggered when a user tries to access the Telnet feature, reminds users to update the device's firmware. Another, dropped as a comment in the source code, repeats a statement from free-software icon Richard Stallman:
> "To any NSA or FBI agents reading this: please consider whether defending the US constitution against all enemies, foreign or domestic, requires you to follow Snowden's example."
>Symantec estimates "somewhere in the order of tens of thousands of devices" are infected with the virus, with infections largely focused on Brazil, China, and Mexico. Resetting a device is enough to remove the infection, but the firm warns that a router may become reinfected over time. "Symantec will be keeping a close eye on Linux.Wifatch and the activities of its mysterious creator," the post concludes. "Users are advised to keep their device’s software and firmware up to date."

The Commodore Datasette has been around since 1977 or so, and the Kansas City standard a couple years before that, so yes, using audio cassettes for data storage is possible. But VHS would be more practical, since it has a bandwidth of ~3MHz versus audiotape's ~30kHz.

You'd be better off getting some old SCSI tape drive and using that. Otherwise... I suppose it wouldn't be too difficult setting up a raspi or some little shitty microcontroller to control some VCR guts.
Hmmm.

In the early 1980s Hewlett Packard were experimentally using standard VHS tapes for backups. They even released a box that could be hooked up for data backup.I know this as fact because I was working for HP at the time, it was released at the same time HP was demonstrating 3.5 inch hard drives with 40MB storage.

your research is off by several orders of magnitude.

They are much improved from older styles of tape as to magnetic resistance. the CIA, FBI, Google, IBM, NASDAQ, NYSE and Chicago Mercantile Exchange and dozens of other major businesses all use mass magnetic tape storage for total catastrophic data loss and recovery.

The sneakernet is also another good reason why high density tapes are still used.

16kHz to answer OP's question for standard audio cassettes

This isnt anything new BTW, there were peripherals in the 70s and 80s that allowed you to store and load data on cassettes as a low cost option instead of diskettes. They were shit. Relatively low capacity (like 200kb), slow, and not random access. Also, it would just crash periodically and the whole process would have to be restarted. The cassette was always a shitty compromise format even when it was "the standard". Reel to Reel was far and away superior but expensive and vinyl isnt portable.

Tape backup at the high end of server farms and such has never gone away but its pointless for users.

Paging Acid or other likeminded folks.

Prefacing this with the fact that I know very little about what I'm asking:

As I understand:
1: A major difficulty in the proliferation of 3D printed guns is getting ammo for them in some places

2: if you take the tinfoil wrapper from gum and apply the metal side to a 9 volt battery it makes fire

3: some old school guns used paper walled cartridges

4: Blackpowder is easier to make our of local shit you have lying around, and lower pressure making it less likely to cause a kaboom.

Would it be possible to make a firearm with a paper rolled cartridge and a 9volt and gum wrapper ignition system with a blackpowder load?

What about injection molding one's own cases? Dave of Vince Gingery wrote a book on making one's own injection molding machine.

There used to be a device called a Tap O Cap that allowed people to make their own percussion caps out of soda can aluminum. I suspect one would be able to use such a device to create a Berdan primed polymer cased ammo using black or red powder and a cast lead or maybe copper bullet.

Walls are generally too thick to work well. To fit in a SAAMI spec chamber and hold a bullet, the bullet will either have to be undersized or heeled. You might be able to swing it with a minie-style hollow base in the former situation.

There's also the possibility of cases splitting so badly as to FTE or not springing back enough to provide sufficient clearance for extraction. With enough experimentation and custom-reamed chambers, though, it's feasible to make old Maynard-style cases from tubing and sheet brass/copper stock. Personally, I'd first try making foil cases a la .577 Snider.

As some of you know, I work on gas turbine engines. As such, I get to play with some cool toys every now and then. Unfortunately I can't post pictures of work stuff, because on the list of things that'll get me fired, posting pictures on social media is right between shooting up the place and using the company credit card to buy hookers and blow. (That's "customer entertainment" only.)

So anyhow, I was using the FLIR to troubleshoot some stuff, and in the process learned a lot about thermography and the electromagnetic spectrum.

Here's a link to the FLIR brand FLIR I was using. Short story: Older model, $6k, 140x140 resolution. Two temp ranges, -4°F to 302°F and 32°F to 662°F.

One of the things I've always wanted to see experimented with FLIR/thermal video and never had is porn/sex scenes. Might be boring. Might be interesting. Never know until you try.

I'd be hot. Measurably.

I'm interested in seeing a large bukkake scene. I'm actually curious what it'd look like with the mix of cooling jizz and fresh jizz.

After a while, it'd probably look like abstract art.

I'm guessing for Predators, it'd look something like tigerstripe pattern.
