Belly or tail lander? Implications pf scifi tech
Shpaget replied to Spacescifi's topic in The Lounge
A "tail" implies a rocket. A sufficiently advanced propulsion system would not require a rocket like configuration. Borg cube. -
Thread to discuss positive things in a general manner
Shpaget replied to GearsNSuch's topic in The Lounge
That sounds awesome! The job, that is. So it's been a few days give us an update. As for a positive thing on my side, I've been working on a control box for a kids model layout, and I'm just very appreciative of a good crimping tool for connectors. Compared to soldering, it's faster, much less fiddly. less prone to failure, and looks better. -
I remember my grandmother had one very similar. She would always take it with her on an evening walk. It worked surprisingly well.

Oh, I didn't buy. I just used their exchange rates to calculate the fees. You're right. I'm not trading, since I don't consider myself good enough to make money Just out of curiosity. You say the graph in first post is from a real account. What are the axis on the graph? How long did you let the bot trade?

ESA, JAXA and CSA to build optionally manned lunar lander
Shpaget replied to insert_name's topic in Science & Spaceflight
If I'm reading the article in OP correctly, 15 kg refers to soil sample mass budget for return from Moon surface to Earth. Also, 90 kg refers to science instruments on top of a rover. Assuming the rover is some 200 kg, the total of ~300 kg is enough for a big guy in a heavy suit. -
Oh. Can you give us more details? How do you deal with conversion fees? For example, if I went to my bank and, using todays exchange rates, converted 1000 € into USD I'd get $1077,49. If I converted those $1077,49 back I'd end up with 924,08 €. That's perhaps a bit exaggerated and I could get better rates outside the bank, but the principle applies, doesn't it? Is the buy/sell automated, or do you have to do it manually?

Trading as in stock market? 5% per month is huge. Well done.

Convoluted and oddly specific arbitrary limitations. FTL drive should not be designed around the role of the vessel. It should be technology driven and the type of vessel that employs it should work with what is available or it just doesn't work. The parameters of the FTL travel should be defined by story - offer the capability needed for the story, but include some limitations, again for the reasons of story telling. Options are: Instant travel, but spool up/cool down time (Battlestar Galactica) Instant start of the drive but finite speed (Star Trek) Special training for piloting or similar limitation that makes it not available to everybody (Dune) Natural wormholes or subspace lanes that put limitations on paths the ships can take (Andromeda). These options are usually well balances, yet flexible enough to give the author some flexibility for future ideas.

From Star Trek Voyager S04E01 Scorpion Part 2. In spoilers because maybe there is somebody out there that hasn't seen it, which they should ASAP.

Both testing and deployment site is not exposed to sunlight. LED roomlights shouldn't produce much IR, but the kicker is that the previous system works fine just a few meters away in the same room. The functionality I get is marginal, but on the good side of margin, so I might just deploy and fix later if needed.

That made me laugh. The problems I face at work are numerous and all equally frustrating. One is the software that runs the layout (I work at a model train museum thing). It runs mostly fine, but if there's a problem with trains that needs manual override in software, there is a roulette table somewhere that if the ball lands on a 00, you get a total system failure where the software forgets where each train is. Hunting down the location of all the trains (150+) manually takes about an hour, which is a bit of an issue if you have customers asking you is it done yet every few minutes. Luckily I usually don't have to deal with this since I moved to R&D, but yesterday was an exception. We were a bit short staffed so I had to jump in and help it have fixed before the announced group of kids arrived. Of course they arrived half an hour early. The other problem, which is more closely related to my responsibilities is the laser trip wire alarm system for the layout. Kids like to touch and we don't like them touching. The configuration of this particular segment that needs protection requires some 40 laser lines. They are not actually lasers, since lasers and kid's eyes don't play well. They are IR LEDs modulated at 38 KHz and the approach worked fine on a 7 meter stretch on another part of the layout. On this particular stretch I can't get 1.5 m to operate properly, using same techniques same LEDs and very similar receivers. Of course, I'm no electronics engineer, so it's entirely possible that I'm doing something stupid.

A bit of a spoiler from the end of the s01e02.

So, the only plane that is comparable in speed with this is the SR-71, which has a total carying capacity of 2 crew and a few cameras. The rest of the plane are pretty much just engines and fuel tanks. Going from that to an airliner is quite a step.

I don't really mind artistic liberties. The overall story seems to check out.

Holey bubbling sluice water cliffhanger in the second episode! Thanks @tater for the recommendation.

https://www.hermeus.com/ These guys want to build a Mach 5+ airliner. They give no technical details about size, capacity, range or anything of substance apart from the Mach 5 number and their wish to do no "R", just "D" part of the "R&D". Apparently they have received some venture capital and their plan is to have something flying in 10 years. My take? A venture caputalist and his money are soon parted. The bad vibes I get from this are strong.

Microsoft announces electronic voting system
Shpaget replied to Shpaget's topic in Science & Spaceflight
I don't mind changing the title, but I disagree with you. Yes, even the MS blog states but it also says: And this here effectively makes it electronic voting system with optional paper backup. It doesn't take much creative thinking to see that even with manually counted paper ballots, this opens a possibility for manipulation during data aggregation. -
https://blogs.microsoft.com/on-the-issues/2019/05/06/protecting-democratic-elections-through-secure-verifiable-voting/ Let me just remind everybody that politics are not to be discussed here. This is about the technology. Tom Scott has a list of things that are wrong with it: I have to agree. There are too many possible attack points that can lead to large scale manipulation. Yes, I know cryptography is complex and there are mechanisms that can be put in place, but there is always a possibility.
