genmud··on Twitch to Cut 500 Employees, About 35% of Staff
I feel like free peering is a thing of the past. Verizon/Comcast killed it by forcing people to pay for peering relations about a decade ago.
genmud··on "Twitter is a ghost town."
I have noticed after the holidays many of the people who I followed on twitter, just… didn’t come back, lol.
genmud··on China's home-grown C919 alights in Shanghai on first regular route from Beijing
“Home-grown” my ass. So much of this plane was built on IP theft, it’s kind of a joke in the aerospace industry. This is the difference between western intelligence agencies vs Chinese intelligence agencies, who use IP they steal to help their domestic companies.

genmud··on Why use strace in 2023? [video]
What SoC are you using out of curiosity?

ARM cortex, riscv and espresif all seem like they have first class support. Unless you are talking about peripherals in which case, why would you expect the language to write/maintain low level drivers?

The hurdles to replace it in micros might be worth it depending on the team size and requirements. Personally, I wouldn't expect it to ever replace existing code bases, but could be a reasonable choice for greenfield designs.

genmud··on Ask HN: Good book to learn modern networking?
I'm still a fan of TCP/IP illustrated (book 1) [1] for understanding the fundamentals. The one from No Starch Press [2] is also a great book.

Personally, I think if you understand the fundamentals, you will quickly realize things like software defined networks and CDN technologies are just abstractions on top of other stuff.

genmud··on UniFi U7 Pro
I wish they would get their shit together and have software that isn't buggy / riddled with security issues. Their march to a cloud dependent offering is so disappointing.
genmud··on IT employment grew by just 700 jobs in 2023
Yes, but I would be interested in the gross income of IT vs other occupations and how that is impacting overall economy.

For example, if you drop 2 IT jobs, but each one is 150k, but you create 4x 60k jobs, it looks like you added 2 jobs, but in reality, you removed 60k worth of payroll income.

genmud··on Drones are the new drug mules
Just speaking from the US side of things, there aren't any 20/30/40/80/120mm AA rounds being produced in mass quantity and it is more of a scaling issue. Systems like CIWS are also incredibly bulky, requiring a few semi trucks worth of equipment to operate.

There are some German AA guns that have been used for counter UAS, but their export laws are a fucking nightmare to deal with if you ever want to sell, give or trade those systems later on.

genmud··on Teaching C (2016)
I'm not saying because they need to understand exactly what code gets generated, compiler optimizations can produce interesting results. What I am saying is the idea that an if statement from an assembly is a compare and a jump... knowing what happens under the hood is kind of important for people writing C in 2024.

Like I guess the point I have to make is that if you are writing C in 2024, there is likely a good reason, and if you don't know what's going on in the assembler, I feel like people are playing with fire.

genmud··on Drones are the new drug mules
High energy weapons and EW are the only realistic way to deal with it without slinging 100k or 2m dollar missiles around. One problem is these missiles still have debris, though less deadly than an armed drone, they can still be hazardous. Lasers and other high energy weapons are probably the most cost effective and reliable solution for sub 10 pound drones. You generally need only knock out the MEMS gyro, overheat a motor or blind its sensors.

The problem is that drones are cheap and easy to slip around defenses. The other issue is weapon system reliability... the US military expects an extraordinary amount of reliability from munitions / weapon systems and they are supposed to be near 100% reliability. When they launch a missile, it's unacceptable for the missile to not launch.

The Coyote[1] is an interesting counter UAS concept and could be much more cost effective solution.

genmud··on Teaching C (2016)
I’m actually of the opinion that C should be taught hand in hand or just after someone learns assembly. It’s admittedly a bit gatekeeper-y, but IMHO C should be thought of with same mindset as you would develop an ASM program, but with a bunch of shortcuts and syntactic sugar.

Without understanding what code gets generated, there are so many footguns it can be dangerous at best. Knowing things like calling conventions and how the compiler interacts with memory are really important.

genmud··on Lower Obesity Rate During Residence at High Altitude Among a Military Population
There was a paper about 10-15 years ago where they mentioned that they noticed decreased appetite and increased metabolism at higher altitudes. [1] kind of goes over this. I used to live in a high altitude town (~ 7000 ft) and definitely noticed that my appetite was much lower and whenever I traveled had much more stamina.

genmud··on New U.S. immigration rules spur more visa approvals for STEM workers
If it's just export controlled stuff(radar, dual use stuff), technically you can hire non US citizens, and IIRC it's actually discrimination if you only hire US citizens. But you need to get export licenses, which they might not grant based on the country of citizenship, and they require permanent residence.

But let's be honest, it's pretty standard practice to require US citizenship.

genmud··on New U.S. immigration rules spur more visa approvals for STEM workers
I don't think it would push down wages for high end talent if you keep the requirements they pay prevailing wages. If anything, it would increase the wages for people.

The point would be that we fill and address the talent problem longer term. AKA if you need to hire foreign workers, you have to invest in developing new talent.

I would say that total comp should be taken into account, but we should take a more strategic approach to addressing workforce gaps rather than just relying on importing talent.

genmud··on New U.S. immigration rules spur more visa approvals for STEM workers
I would love to see a revamp of visa system that when someone is sponsored by companies they are required to do a 1:1 match for scholarships on the salary of someone who they are sponsoring. Alternatively make the minimum $100k or max $250k.

As someone who had someone come over on a O-1 visa, I 100% would have been willing to pay double for that person specifically.

It also removes the common issue of people who are hiring people below market rate or are trying to push salaries down for certain industries. It makes companies really make sure they actually need that technical expert from overseas.

Then open it up to everyone else if there are quotas.

genmud··on Ask HN: What's your go-to wireframing tool for MVPs?
For me personally, I am not a designer. So I use a hard cover, square, xl moleskine notebook[1]. I like it because I can have things on a timeline, and look at historical revisions/sketches/notes.

genmud··on The unfortunate math behind consulting companies (2011)
> Sorry, I didn't understand what is the argument bhind your first paragraph: advisory vs. consulting.

It was more to clarify it was proserv work than anything.

In the context of SaaS/tech, typically professional services is implementation, maintenance or break/fix of specific products or technology. Advisory work is supposed to be independent work where you are being paid for (what is supposed to be) unbiased opinions and strategy.

It's the difference between staff augmentation / project work and strategic / planning work.

genmud··on The unfortunate math behind consulting companies (2011)
Yea, but that type of consulting is typically billed as professional services(or similar), not advisory work.

If product companies are smart, they might put this role under costs to acquire customer vs services and then have it as a fee for onboarding. I can’t remember the details, but I’ve been told having really profitable services can really complicate VC/fundraising.

genmud··on LED Industrial Piercing
I live in a place where it didn't really take off like some regions. There are a few with some equipment, but whenever I really inquired it was kind of "we have it, but nobody can use it themselves".

I totally understand though. People don't realize how expensive precision metalworking stuff is. And that's before you start to insure the place.

For something like a really rigid CNC (not a desktop sized one or for wood), someone needs to come up with a reasonable cost machine that can hold thous and has a spindle that isn't stupidly overpriced.

genmud··on JetBrains forces AI freemium plugin that cannot be completely removed into IDEs
Yep, that's what the invoice says... was $90 since like 2014 or 2015 when I bought it.
genmud··on Show HN: Chrome Reaper
Very cool to see government sponsored open source.

IMHO investing in open source is one of the most strategic things that the US government can do over the upcoming decades. Think about how many trillions of dollars in value has been built on open source software in the US... it's mind boggling how much ROI there is on that stuff.

genmud··on JetBrains forces AI freemium plugin that cannot be completely removed into IDEs
I mentioned in another comment I must have been mistaken, I had the all products pack. I went from $89/year in 2019 to $149/year in 2022 which was a 67% price hike.
genmud··on JetBrains forces AI freemium plugin that cannot be completely removed into IDEs
I had the all products pack, so I guess it wasn't just ultimate. Between 2019 and 2022 it went from $89 to $149 + tax, so 160/year. I did not receive a 67% increase in value during that time.

I used to have the same view about idea vs vscode, but the MS provided plugins are solid these days and some of the other ones that are community are equally rock solid.

Things where IntelliJ used to just beat the crap out of code, like managing development environments or debugging are now either on par or better than IntelliJ. I even have it setup for remote debugging and serial debugging embedded devices.

genmud··on JetBrains forces AI freemium plugin that cannot be completely removed into IDEs
I finally cancelled my subscription for their ultimate package as it just kept going up and up in price. They used to be really good for having 3 year discounts, and paying $80 or $100 for a fairly good ide wasn't the end of the world, but VSCode has gotten really good and paying like 160/180/200 a year out of pocket just doesn't make sense to me.
genmud··on 3M knew its chemicals were harmful decades ago, but didn't tell the public
You must be new to politics, lol. I am not sure if modern politicians even pretend to represent their constituents these days. Special interests first, party second, constituents only during an election, but only if you have a close race.
genmud··on Security Issue: Cloud Site Manager presented me your consoles, not mine
Hint: they haven't put controls in place, and it will happen again.

Unifi is one of the companies with awesome potential but they just seem to whiff it constantly on security and software.

genmud··on Rishi Sunak considers curbing social media use for under-16s
I know your being sarcastic, but I genuinely wonder if the net benefits actually outweighs the problems.
genmud··on Intel launches Core Ultra processors
Funny enough, we paid dell to support a number of IBM laptops at one place. Was kind of funny.
genmud··on Intel launches Core Ultra processors
Anecdotally, over the last 15+ years working in tech, only 2 of my employers out of 7 were windows shops. Over the last 10 years it has been 0.
genmud··on Intel launches Core Ultra processors
First off, that is a really faulty assumption. Enterprise laptops make almost nothing for most laptop manufacturers. When I bought Dell laptops at a F500, they were selling us laptops at cost and only making money on support / software contracts. HP/Dell/Lenovo are all making between 2-8% on their profit margin vs 25% with Apple.

Compared to 10 or 15 years ago, mac laptop adoption is increasing. It feels like most tech companies or software engineers are using macs.

Dell, HP and Lenovo all ship massive amounts more laptops, but make a fraction of the margin that apple does on their hardware. IIRC apple made more profit than all 3 combined. And each one of those has software arms of their companies that help their bottom line.
