penagwin··on Soldiers speak out about being blocked from repairing equipment by contractors
It depends so much on what it is, a simple single component swap seems unlikely to cause issues.

Sure I understand that a full diagnosis/repair of say a water damaged board I might not trust, but if it's just a port or a capacitor then it seems unlikely to cause massive issues if the person has any EE background whatsoever.

penagwin··on Heart inflammation cases in young men higher than expected after mRNA vaccines
As a data oriented person I would prefer if the percentage is always available, otherwise I have to calculate it to use with other numbers.

For example: (chance of getting covid) * (chance of specific side effect) = chance of getting covid and experiencing side effect.

penagwin··on Hetzner has banned crypto mining and Chia farming
I'm in the market for a storage server so hopefully this brings us some stock!
penagwin··on Companies may be punished for paying ransoms to sanctioned hackers
I'm not 100% sure but I'm pretty sure that the sanction laws cover proxies like that.
penagwin··on Why is the Gaza Strip blurry on Google Maps?
I'm not sure about the immediate part. My area only updates every few years on Google maps, they don't exactly provide real-time data (and never meant to)
penagwin··on Stadia’s VP and head of product leaves Google
Not officially _yet_ but between the VP leaving and some other signs, it does appear that Stadia isn't likely to last a ton longer.
penagwin··on Proposed futex2 allows Linux to mimic the NT kernel for better Wine performance
There are pieces of linux - say the networking - that already don't meet many people's use cases. People seem to like BSD for certain networking stuff due to differences in the respective networking stacks.
penagwin··on Coinbase opens at $380, up 60% seconds after opening
> Yeah, which means that reporting the value of a security seconds after opening is an act of advertising, not one that evaluates the securities actual value.

Do you have any other way of evaluating it's value? You have to evaluate it somehow because it's worth more than 0, your broker can't give it to you for free. There is a real bid/ask spread, and I'm guessing you don't want to buy with no idea what price you're buying for.

The pricing is inefficient after opening but it's still real. Also who's to say it'll be over priced? It could just as well be underpriced immediately after listing. I'm not sure how this counts as "advertising"

penagwin··on Coinbase opens at $380, up 60% seconds after opening
It takes time for price discovery - A simplification would be to imagine a simple moving average of say N, Sure it looks very smooth, but if you look at the very beginning where there was less then N datapoints it'll be all jagged because there's not enough data yet.
penagwin··on Surface Laptop 4
I worked in computer/phone repair and a bit of design,

You can see [1] that they are using multiple cells essentially taped together to make their "battery". This isn't uncommon, especially recently in smaller devices, as it lets them fit unusual shapes and other size issues, and saves space because you don't need a shell around them. The biggest (only?) issue is that you have a very delicate batteries taped together, if ripped/torn they may explode. To add to this, because they aren't riggedly attached, they are more prone to movement (and thus tearing). Their solution was to use adhesive across the bottom to make sure they are all firmly in place [0].

From a repair perspective this isn't great. It's not hard to remove if you have a heated plate, isopropyl, and patience, but not very user friendly. The best thing they could do to fix this would be to give the battery a rigid enclosure, but that will of course eat up valuable space, and I have no idea how that would affect the rest of their design. They could also use different tape that's easier to remove, but they may see the taped-together battery as something they don't want to be liable for people replacing (in case they tear it), so I really think the best solution is a rigid shell for the batteries.

tldr; This appears to mostly be a design limitation instead of a purposeful decision. I wish they'd change their design instead though....

penagwin··on How Iraq’s crystal meth epidemic is ravaging the nation
A large part of the issues from drugs are contaminations and inconsistent dosing. Prohibition also pushes people to make/use higher concentration drugs, and forces people to use drugs they can get vs drugs that are safer (meth vs addaral). And forces them to use unchecked (and often untrustworthy) sources.

The idea is that legalization should bring addiction resources, harm reduction, education, and cleaner drugs.

This removes the infamously dangerous "drug deals", "bad batches"/lacing, removes stigma and legal barriers that prevent addicts from recovery, and should make it easier for users to recover.

penagwin··on Argentine president positive for coronavirus after vaccination early this year
Even the better vaccines only have about a ~95% efficacy in preventing symptomatic covid. Notice that's not including asymptomatic covid.

The most important vaccine statistic is the ( I think still current) 0 deaths in the vaccinated groups.

penagwin··on Crazy fast build times, or when 10 seconds starts to make you nervous (2012)
I definitely agree things should be tested on realistic hardware - but one of the big reasons for me at least is using a decked out machine is because of all the dev tools + browser tabs, etc. IntelliJ might be using 6GB, chrome another 6GB, 6GB for teams/discord/figma/gitkraken/vscode/spotify. That's not including any image editing software or vm's but I'm already needing over 16GB of ram.
penagwin··on Why forex trading is exploding across Africa
Ah my bad, I don't have much experience with forex
penagwin··on Why forex trading is exploding across Africa
I guess but then again there's almost 10 million people now on WSB - and people can say anything.

I'm not sure how this is different from say bitcoin, where I've heard estimates of "100k by the end of the year" since 2016

penagwin··on Why forex trading is exploding across Africa
> ~10% annual returns

That kinda checks out to me given the overall markets tend to return ~7% to 8%

I don't think it's fair to call the GME short squeeze a scam, it was just a community taking advantage of the mathematics at the time. There wasn't any misleading information or false promises, just people FOMO'ing in with the bubble.

EDIT: Also GME is at 240, it's not even a short squeeze anymore it's just bizarre

penagwin··on Reddit hires its first chief financial officer as it prepares for an IPO
I doubt this, reddit seems to have embraced the attention wsb has gotten them (see their super bowl ad).

While I can see shenanigans with replacing mods, I don't see them shutting down the subreddit.

penagwin··on 100Mbps uploads and downloads should be US broadband standard, senators say
100Mbps up as a standard? One can only dream. Comcast's highest residential offer is 1Gbps down (yeah right) and 35 mbps up.

My other option is DSL with Att, a max of like 30Mbps down...

penagwin··on Robinhood is facing nearly 50 lawsuits over GameStop frenzy
Is there a source for this? I watched their testimony to congress and they said they aren't even able to place naked shorts/calls.

You can still get a short interest above 100% without selling naked calls/shorts.

penagwin··on Universal Radio Hacker: Investigate Wireless Protocols Like a Boss
Do you have any experience with the limesdr? I've been eyeing those for a bit
penagwin··on Sneakerheads have turned Jordans and Yeezys into an asset class
Oh they already exist :D

Heck I have a feeling adecent number of people who work on such operations are on HN

That just means you need more projects :D
penagwin··on rpi-open-firmware: open-source VPU side bootloader for Raspberry Pi
> Arduino because even though it's sizzling fast compared to a $15 RPi Zero W

Wait are we talking about the arduino uno/nano/pro? Because those are far slower then the raspi zero w, with a magnitude less memory.

penagwin··on Dogecoin Surges as Reddit Traders Push to Make It the Crypto GameStop
Gamestop was a short squeeze though - Dogecoin isn't in that same position as far as I know?
penagwin··on Linux Running on Apple M1
I'm not sure how buying a M1 macbook pro will help considering it also has soldered ram?
penagwin··on SpaceX acquires former oil rigs to serve as floating Starship spaceports
> Also rockets pollute, which is another reason to keep them far away from people.

The falcon rocket's use RP-1 which is kerosene, so the exhaust is just H20, and C02 - Granted C02 isn't great, but it isn't too toxic.

penagwin··on Satran Satellite Tracking Antenna
Hmm this appears to be an alt-az mount. If they made a future version as an equitorial mount it would be even better for radioastronamy, and if it's strong enough astrophotography too. They're a lot more complicated though so it's understandable why they didn't go that route.

Especially if this is meant more for geostationary satellites and I'm guessing most satellites like NOAA aren't too bothered by the slightly rougher tracking. Plus I guess the passes are fairly short anyway...

penagwin··on Beaker Browser – experimental peer to peer web browser
Where did you find community websites for it? I can't find any list of links, and none on hashbase load for me at all.

I can't find any examples of community links or anything built with this
