genmud··on We saved battery in our ESP32 WiFi circuits (TCP vs UDP)
Depends on your budget, but the JouleScope [1] can measure down to half a nanoamp. Absolutely amazing piece of kit for the price ($1,000).

They also have a python library [2] so you can do lots of stuff inside Jupyter.

genmud··on TSMC founder says Intel has neither a strategy nor a CEO
I don't think that they should have TSMC do everything, but being coupled at the hip with the foundry business has not been, and is still not a winning strategy.

If the foundry business could execute (in timelines, in yields, and in sales), then having a vertically integrated company makes a ton of sense. However, that has not been the case for a while and will take years to get them back in a position where they can execute on the foundry side.

Right now the market and the board is dealing with the company equivalent of having your 25 year old kid stay their home rent-free, while spending tons of money, and getting piss drunk, then taking a shit on the hallway rug. At a certain point, you have to kick them out and tell them to get their life together, because the alternative is being homeless.

What they are doing / have done is obviously not working, they aren't being judicious in their spending, they aren't innovating, and everything is being dragged down due to institutional mediocrity.

genmud··on Intel announces retirement of Pat Gelsinger
I think that Pats strategy is what the fab needs to do to be successful.

However, I think the fab and design should be separate companies, with separate accountability and goals/objectives. There is just too much baggage by keeping them coupled. It doesn't let either part of the company spread their wings and reach their full potential when they are attached at the hip. From the outside perspective, that is the thing that Pat has seemingly been focused on, keeping it together, and its why people have lost faith in his leadership.

I also don't think that from a investment / stock standpoint that accelerating the depreciation / losses related to restructuring on the most recent quarter was a wise decision, since what Intel really needed was a huge win right now.

genmud··on Wordpress.org locks out developer of Pods, plugin similar to ACF
I'm starting to think this Matt guy might not be the right person for leading the Wordpress community.
genmud··on Ask HN: What will the WordPress meltdown mean for Automattic's other products?
Anecdotally, I'm a near daily user and have noticed the platform has significantly more latency, a massive uptick in spam as well as strange / intermittent bugs.
genmud··on Show HN: 4B+ DNS Records Dataset
That would be incorrect, they get subdomains for passive dns feeds.
genmud··on Show HN: 4B+ DNS Records Dataset
Neat! How is this different than domaintools/farsight [1]?

Passive DNS [2] has been in my toolbox for 15+ years, and is invaluable for security research / threat intelligence. Knowing historical resolutions to something are so helpful in investigations.

For anyone interested, they should check out the talk by one of the DomainTools people [3] on how it can be utilized for investigation.

Are you passively collecting this data, or actively querying for these records?

genmud··on Ask HN: What do embedded engineers do?
Software companies have focused on efficiency, which is why the cost of building software has steadily decreased over the last 30-40 years.

From my perspective a lot of that is because the tooling and mindset for hardware is stuck in 1980s/90s. Compared to modern software development, there is very little to no automation in hardware design.

Things like CI for hardware designs and even automated version control are just starting to become a thing in the embedded space. Automation like building Bill of Materials, build pdfs, gerbers are not in any way optimized.

Scaling embedded stuff (design, manufacture, etc.) is very much a linear thing today, which is why salaries are low.

genmud··on Raspberry Pi Pico 2 lands with RISC-V cores
Its actually really nice and well supported. I personally prefer the sdk style that PICO does it over the cubemx stuff.

genmud··on Dell employees used company's corporate survey to tell bosses post-RTO feelings
... and then they promptly ignored the results.
genmud··on Apple's risky bet on CarPlay
I sold my GM truck because of how horrible the head unit was. I am still driving my 8 year old f150 because the infotainment system works fairly well.
genmud··on Ask HN: What job titles involve designing chips?
ASIC, RTL, tapeout, FPGA and Verification are all keywords you can use to find job descriptions. Each company is a tiny bit different, so there is a fair bit of variation.
genmud··on TCS sued for discriminating against Americans for H1Bs
Good. Tata, wipro and the other Indian H1B shops have been gaming the system for decades. The way they do things are exploitive, bad for H1B employees, bad for US employees and bad for the employment market.
genmud··on Why does part of the Windows 98 Setup program look older than the rest? (2020)
IIRC you could actually run XP themes on 2k3 if you started the theme service. Under the hood they were almost the same exact same kernel (I think server / 5.2 had a slightly different IP stack and some server tweaks for task scheduling, shadow volumes and memory caching).

Likewise if you wanted the non XP (Luna I think it was called?) styles you could just stop the theme service and it was effectively win2k style.

genmud··on French company ramps up production to meet demand for its military drone radar
The US has had this capability for quite a while with the LCMR (AN/TPQ 48/49/50), which has been produced in large quantities (1k+, per mfg) and at least a few were in Ukraine.
genmud··on It's time for a hard reset on notifications
Yea, I pretty much turned off notifications off across the board. It's gotten to a point where I don't want anything pushed to me, only pull, because there is no granularity in notification systems.
genmud··on A16Z blogs are just glorified marketing
Most blogs are just glorified marketing, full stop. A blog that isn't marketing is the exception, not the rule.
genmud··on Why are most sofas so bad?
You are absolutely incorrect. Most of the LED bulbs on the market have incredibly poorly designed power circuits that absolutely cook the passive components.
genmud··on Boeing ousts 737 MAX chief
I doubt it will ever be certified by any aviation authority outside of China, which will pretty much make it the tu204 of CN.
genmud··on Nine US states are teaming up to accelerate the adoption of heat pumps
What a clickbaity, poorly written and sensational article.
genmud··on Ask HN: Does anyone care about OpenPOWER?
Nobody cares about it because unless you use IBM, or use it in some embedded use cases it’s irrelevant.

It’s irrelevant because while they would openly license it, it wasn’t open source as you think about it traditionally and would require you to cross license derived technology to the consortium, which was effectively Freescale and IBM if I recall correctly.

IIRC they have only recently open sourced and freely licensed the ISA. Even then, there isn’t much interest in it outside big iron or niche platforms.

genmud··on New IBM LinuxONE 4 Express – Rack-mounted pre-configured Linux mainframe
When I moved from a tech company to an aero company who used mainframes, there were literally hordes of IBM contractors who helped maintain the mainframe environments. Getting anything done in those environments was a multi month project, even for basic stuff like patching the OS. There were probably 2 or more sysadmins per rack, employed to just keep the damn lights on those boxes.

For context, there was about 1 admin for every 400 servers at the tech company, and that was for the entire tech stack (LAMP).

Mainframes require a lot of care and feeding. In my experience, having worked at 3 different companies who relied on them (education, aero and finance), their capex is higher, their opex is higher and their uptime / reliability is entirely dependent on the facilities / staffing.

genmud··on New IBM LinuxONE 4 Express – Rack-mounted pre-configured Linux mainframe
> Mainframes are unbelievably powerful, feature-full, and cost-effective.

Maybe things have changed in the last 10 or 15 years, which is the last time I had a legit mainframe at a day job, but back then none of those things were true if you looked at it more than 20 minutes.

I seem to remember nothing being included in the base mainframe… when you started to add things like DR and data duplication and virtualization, it became extremely expensive. Like on the DB side, effing Oracle was much cheaper.

genmud··on Cops bogged down by flood of fake AI child sex images, report says
If this is real, please hit up ICE C3 [1]. They specialize in investigations for this type of thing, specifically sexual exploitation and trafficking.

genmud··on Reddit Advised to Target at Least $5B Valuation in IPO
Hope they get it, because that will be great for the valuation of other, more successful companies.
genmud··on Inclusive Language for IT
Just think of how many people were involved in making this happen. Like nobody thought to themselves, wow... this is fucking stupid and is really cringe, maybe we shouldn't put it out for the world to consume.
genmud··on Thousands of small businesses are struggling because of R&D amortization
Which is why so many are having issues. Having to come up with a 30-60k per engineer on top of your expected salary burn rate can have serious impacts to a startup runway.
genmud··on Thousands of small businesses are struggling because of R&D amortization
Taking a 30% hit on business income is a significant thing.
genmud··on It sure looks like X (Twitter) has a Verified bot problem
Inauthentic (bot) behavior on Twitter has gotten insane, nearly any political or social issue is like watching ants fight another colony and pick at each other.
genmud··on Air travel is not ready for electronic warfare
Radio goes through and reflects off things, including aircraft. GPS signals are incredibly weak, and even if an aircraft attenuates or reflects 99.9% of the signal, a ground based system will nearly always be able to overpower it.

It can be as simple as reflecting off the tail section of the aircraft.
