virtue3··on Nvidia is now more valuable than Amazon and Google
This has happened before and it will probably go the same way. Software and compilers will make up the difference, or hardware will become so cheap and ubiquitous it wont super matter.

In 3-5 years what will a 10% performance difference matter to you? Then calculate how much that 10% performance difference is going to cost in real dollars to run on nvidia hw and then the fun math should start.

virtue3··on Ventum, Dimond, Cervelo – Why do these triathlon bikes look so weird?
I used to do tri's 10 years ago. Was sorta into it. Friend was super into it.

Tri athletes are super into aerodynamics over weight (weight is still important but aerodynamics are more so IE disk wheel inserts etc etc). The reason being because the more effort you spend on the bike the more gassed you are on the run coming up after. (also see below there's no pelotons in tris/TT)

Because of the square law of wind resistance basically bike times haven't gotten faster but run times have because riders are conserving more energy while riding at the same speed because of efficiencies in the bike designs.

Also you are never allowed to draft in triathlons and must maintain a certain distance behind the rider in front of you unless you are passing on the side unlike

virtue3··on Ventum, Dimond, Cervelo – Why do these triathlon bikes look so weird?
Carbon fiber is extremely durable when it is designed to be stressed in the directions it's designed for.

For instance if you eat shit and fall laterally the frame is likely to crack :).

When you invest in these kinds of bikes you end up having to get them x-rayed after accidents to verify they aren't having sub-surface cracks and are safe to ride.

Aluminum will also stress crack and just fracture.

Steel is dramatically more ductile and will most likely deform instead of catastrophically failing.

virtue3··on A French village that voted to ban scrolling in public
Nothing is more American than taking government money and then not paying your workers enough on top of it requiring your customers to determine if your workers receive a fair wage or not.

It's like how CA taxes you on your unemployment insurance income.

virtue3··on Lag in Cybertruck's drive-by-wire system
So if you operate a bicycle you might understand what's actually going on here a bit more.

The first parts of the movement are actually quite responsive but don't result in a huge change.

If the wheels moved as the drive dictated the car would flip over. You can't just magically make all the forward momentum go lateral without relying on road and tire friction to get the job done. This can hit limits / you just end up skidding the tires and going ass over end instead of turning because you yanked the wheels too dramatically.

It would be like riding a bicycle and then turning the handlebars completely to one side while going at a good pace forward.

You could argue why isn't the car just doing it because they're at a standstill and it should be safe to do so? It's probably a sane default in case there are no sensors / no velocity reading / etc.

virtue3··on OPML is underrated
XML was/is great. It was the issue with people abusing the shit out of CDATA and comments to do meta programming inside the XML and making it an absolute nightmare.

I believe it was an additional reason why comments were excluded from the JSON spec. I can't find the exact quote but Crockford's comment about excluding them for parser directive reasoning is pretty bang on considering usage of JSON primarily as an interchange format (and evidence of a good decision based on it's staying power).

virtue3··on Nine US states are teaming up to accelerate the adoption of heat pumps
places where heat pumps are not going to work well when it drops to freezing / below freezing.
virtue3··on Nine US states are teaming up to accelerate the adoption of heat pumps
I believe they run a heat conductive fluid through heat exchange coils in the ground. This allows you to pump heat into the ground during winter and extract said heat (not sure how accurate this is) during the winter.
virtue3··on Funimation End of Services
Actually it's worse than that...

Funimation AQUIRED crunchyroll. Then changed their name. So technically it's still funimation under sony.

virtue3··on Canadian government banning Flipper Zero to combat auto theft
Nah fuck this.

Someone on the plane I was on kept triggering it to do bluetooth attacks ('not your airpods') while I was trying to read (and have my earphones on connected via bluetooth so fuck me right?).

There's hacked firmware's you can install [0]. I understand that there are probably tons of other devices like this out there but this one was SO fucking popular and easily accessible.

I've already seen this thing abused and used in a super obnoxious way. Frankly I think you should be arrested for having it on in the passenger cabin of an airplane.

virtue3··on SQLite-Web: Web-based SQLite database browser written in Python
if it's built in house it's probably got some business logic / rules built into it.

This tool wont necessarily know about any specifics about how the database relates to your business.

virtue3··on The growing inequality of who gets to work from home
How many bad economic decisions were based on cocaine usage back in the day? I think the point is that with higher paying and salaried jobs you are practically exempt from having repercussions due to drug usage while a lowerpaid wage worker is constantly in fear of getting fired over it.
virtue3··on Post-mortem for last week's incident at Kagi
I think your bit at the end is the most important.

ANY communication is better than no communication "everything is fine, it must be you" is the worst feeling in these cases. Especially if your business is reliant on said service and you can't figure out why you are borked (eg the github ones).

virtue3··on A Love Letter to Tinkerable Software
I did the same thing moding a game I loved back then on my mac via ResEdit.

So damn handy. And set me off on the path of programming for sure.

virtue3··on The day I started believing in unit tests
according to some studies it's around 50 bugs per 1,000 LoC.

So that puts it at about 1 bug per 20 LoC

Some estimates are something as high as 75 bugs per 1,000 LoC but that many bugs don't make it out to customers because of QA / Developer actions. So yeah, right on the money.

virtue3··on In 2024, Intel hopes to leapfrog its chipmaking competitors
Does intel actually have success in this space outside of forcing government entities to use their foundries for what I assume is national security level projects?

Quick google on who their foundry customers are appears to be mostly defense sector.

I have heard that intel has not been the best at working with other customers because they have been so vertically integrated for the entirety of their business it was difficult for them to work with others.

virtue3··on The Final Speech from The Great Dictator (1940)
I know a lot of people here are missing the mark - the issue here is EMPATHY not -feelings-.

"We all want to help one another. Human beings are like that. We want to live by each other’s happiness - not by each other’s misery. We don’t want to hate and despise one another. "

"We think too much and feel too little. More than machinery we need humanity. More than cleverness we need kindness and gentleness."

Please take in the WHOLE message before dissecting a single sentence.

virtue3··on Polish Hackers that repaired DRM trains threatened by train company
yeah screw this. if they are claiming that they hacked their DRM they should absolutely counter sue that this DRM counts as sabotage and/or domestic terrorism. There was literally code in there that told the trains to stop working after X date if it sat still for X amount of time.

That's bonkers. And criminal.

virtue3··on Interview: Epic CEO Tim Sweeney after Google antitrust win
You are dismissing a lot of things.

Steams memory footprint is generally lower. The social aspect of it actually works and can be disabled to free up resources (first mover I'll admit). And the UI is dramatically less offensive than the other "game launcher/stores"

Steam gives me the option to launch into my library instead of the store which makes it feel dramatically less "blah".

In comparison, just to play diablo IV I had to click off two popups in the battle.net launcher of "buy this".

When you add shortcuts to games on your desktop it bypasses the steamui entirely and just launches the DAMN GAME. (it still does do an update/validly check with steam if you are connected to the internet tho).

virtue3··on White House threatens to veto anti-EV bill just passed by US House
Another point to consider here.

Even if EVs are powered by fossil fuels. A powerplan producing electricity and transmitting it to your house is orders of magnitude more efficient than generating energy from gasoline in a motorvehicle using an internal combustion engine.

Also we can curb emissions at the power plant and track them dramatically easier.

And more EVs does not mean more power plants turning on per se. Most EVs are charged at night when power usage drops dramatically (and when you get cheaper rates on your electricity).

The real answer here is using more green house gas free power options like nuclear and solar and wind. I doubt we'll see much nuclear in the near future because it is so cheap to create solar and wind farms at this point and there's dramatically less risk despite it being dramatically less productive.

virtue3··on Amsterdam Switches to 30 Km/h on 80% of its Roads
Yeah it's a known thing now that widening highways / adding more throughput does not ease congestion etc.

virtue3··on A decade of Have I Been Pwned
Jobs can ask if you have ever been arrested outside of CA. (Note: not convicted of a crime).

Also you are going to spend a long time being arrested before the appeal goes out.

"In California, a criminal appeal can take several months to several years. The length of time depends on the complexity of the case and how quickly it moves through the appeals process."

virtue3··on GitMounter: A FUSE filesystem for Git repositories
potentially? but you can also extend a patent by adding to it by patenting an improvement on the patent. :/
virtue3··on GIMP 3.0 has a release schedule
From what I understood about GIMPs development is that they have to purposefully make things "different" from photoshop so as to not get sued. Which makes going from PS to GIMP incredibly painful (I too, tried a few times).

I think if you come into GIMP fresh without using other tools it is probably beter.

I usually ended up relying on paint.net back in the day instead of GIMP on windows tho.

virtue3··on Panama Canal is so congested that one ship owner paid $4M to skip the line
I don't think the article mentions this but this is directly related to the drought in Panama.

Apparently they had a huge lake reservoir for storing freshwater that was then used to fill the locks in the canal. And then subsequently release into the ocean.

They haven't gotten the usual rainfall and this is causing serious issues.

virtue3··on A Nuclear Renaissance Is the Best Path Forward
Sunlight: 1.6e-6 MJ/m^3

(I do actually think solar will be the most useful energy source going forward)

virtue3··on Forests with multiple tree species are more effective as carbon sinks
Trees actually carbon sink via growth aka creating wood. The CO2 they breathe in is turned mostly into growth / basic functioning.

So no, you are NOT destroying the potential. In fact, if they grow and die and rot they are going to essentially release all the CO2 they captured.

https://extension.psu.edu/how-forests-store-carbon

So converting mature trees into lumber is essentially locking out the carbon capture more dramatically, especially if used in long term uses like housing etc. Being turned into firewood would be drastically bad for CO2 capture.

What am I missing that makes you think I don't understand?

virtue3··on The US Supreme Court says it is adopting a code of ethics for the first time
Agreed. The most "long term" effect a US president has is nominating supreme court justices.

I also fail to see how a "code of conduct" might change the way individual justices interpret the current constitution.

Worse yet, who is writing the code of ethics? Is it going to be a constitution v2? Constitution-lite?

virtue3··on Forests with multiple tree species are more effective as carbon sinks
Interesting.

I looked up the world consumption of lumber in 2018 (pre-pandemic stuff). ~ 2.2billion cubic meters, a cubic meter of wood is ROUGHLY(really depends on species) 0.55 tons.

So If we doubled lumber production (which would help housing/construction and a lot of other sectors) wed at least offset the carbon created by roughly half.

Still wont come close to solving our CO2 emission issues but interesting because we could "get something" from the lumber vs just storing CO2.

Assuming 100% carbon capture into wood weight which is not realistic but I think it's a good thought exercise.

virtue3··on Why Is It So Difficult to Map the Ocean?
To be honest; that is actually a pretty dramatically good operational excellence.

I wouldn't be surprised if the uss connecticut was a resolution issue with the mapping system. And also I think it might be hard for the USN to get accurate maps of the south china sea currently.

"San Francisco's captain Commander Kevin Mooney was reassigned to a shore unit in Guam during the investigation of the collision. The Navy concluded that "several critical navigational and voyage planning procedures" were not being implemented aboard San Francisco, despite Mooney's otherwise remarkably good record. Consequently, the Navy relieved Mooney of his command and issued him a letter of reprimand."

"The seamount that San Francisco struck did not appear on the chart in use at the time of the accident, but other charts available for use indicated an area of "discolored water", an indication of the probable presence of a seamount. The Navy determined that information regarding the seamount should have been transferred to the charts in use—particularly given the relatively uncharted nature of the ocean area that was being transited—and that the failure to do so represented a breach of proper procedures.

Nonetheless, a subsequent study by UMass Amherst indicated that the Navy's charts did not contain the latest data relevant to the crash site because the geographical area was not a priority for the Defense Mapping Agency"

source: https://en.wikipedia.org/wiki/USS_San_Francisco_(SSN-711)

So it looks like the USN charts are not exactly cheap to generate. And there is a large human element of knowing where the charts are mostly accurate and where there is information missing.

Also keep in mind both of these are attack submarines and not Ohio class which generally are routinely patrolling the sea very deep and remaining as operationally quiet as possible to act as nuclear deterrents.

I think their track record is more interesting because they have to patrol and be extremely quiet (zero sonar).

The SSN/fast attack subs usually are escorting other groups / actively following targets so they end up in situations they can't entirely control.
