williamDafoe··on Using an 8K TV as a Monitor
You COMPLETELY missed the elephant in the room : 8K TVs have really, really massive CPUs that waste a TON of power (150-200w for the CPU, 300-400w for the TV, often!) Think 8 cores of the fastest arm 64-bit processors available plus extra hardware accelerators! They need this extra processing power to handle the 8K television load, such as upscaling and color transforms - which never happen when you are using them as a monitor!

So, 8K TVs are a big energy-suck! There's a reason why European regulations banned 100% of 8K TVs until the manufacturers undoubtedly paid for a loophole, and now 8K TVs in Europe are shipped in a super-power-saver mode where they consume just barely below the maximum standard amount of power (90w) ... but nobody leaves them in this mode because they look horrible and dim!

If everybody were to upgrade to an 8K TV tomorrow, then I think it would throw away all the progress we've made on Global Warming for the past 20 years ...

williamDafoe··on How the iPhone 16's electrically-released adhesive works
The battery measurement software will never work again with any third party battery replacement. You will never know your actual battery value and the phone may shut off when there is plenty of juice available. Also Apple has software to detect if any part of the phone is replaced and will refuse repairs if any part is replaced. I was told this by the Best Buy authorized repairman as he spent 20 minutes checking my phone and I was told not to leave because they would refuse the repair if my phone had been touched!

williamDafoe··on Panic at the Job Market
Three reasons for techmageddon right now. (1) USA had a boomer savings bubble 2010-2022 with boomers in the peak savings years of their lives, resulting in the lowest interest rates in a century, never to return, (2) Covid19 created a work from home and therefore tech bubble, pulling lots of demand forward, (c) IMHO after a decade of lies from FAANGs about how easy it is to get a $200k salary, and how easy it is to sustain these 60hr/wk jobs (impossible; turnover rates are very very high on purpose), all schools are overproducing CS grads. The three of these mistakes have created a perfect storm, worse than the Y2000 bubble ...
williamDafoe··on Show HN: I made a puzzle game that gently introduces my favorite math mysteries
I remember when our neighbor Ken Appel proved the 4-color theorem (together with help from Arnand Haken). He had help from his teenage kids (Andrew, Laurel, & Peter) who helped him to check the output of the computer program that generated more than 1,000 different patterns and colorings to ensure that they could all be colored with only 4 colors. Andrew (son of Ken Apple) today teaches at Princeton University. https://www.cs.princeton.edu/people/profile/appel
williamDafoe··on An interview with AMD CEO Lisa Su about solving hard problems
AMD basically did not have any money from 2010 until 2020. They were teetering near death. No money for r&d no money for new features in their gpus no money no money no money. There excavator architecture was extremely foolish trying to support multiple instruction dispatches with only 1 ALU and FPU per core! This was corrected with Ryzen and the last 4 years they have been able to pay off their massive debts, especially with the 5000 series!

Going forward I expect we will see much more innovation from them because now they have some spare cash to spend on real innovations hopefully in hardware AND software! Note that Intel is much worse than AMD in software!

williamDafoe··on An interview with AMD CEO Lisa Su about solving hard problems
Intel went into Rest & Vest mode after Haswell (4000 series) in 2013 - they hardly improved until 2020 - 6 lost generations of relabeled CPUs like 13000 - 14000 series (lots of money paid for innovative new igpu marketing names like 520 and 620!). They found out that community college talent does not make good employees in the C-Suite ... The iris pro 5200 (2013) wasn't improved upon until 2020 !
williamDafoe··on My dad and I replaced a 100MB HDD with a 1GB HDD for $100. When did this happen?
1995 is too early. I am guessing 1998-2004. Was the 1GB drive the state of the art? I was buying my sons 2GB drives in the early 2010s for about $100 - you just didnt need that much storage before games like flight sinulator and forza horizon blew up ...
williamDafoe··on The Lunacy of Artemis
This is false most of the fuel is gone by the time it lands and most of the payload is up high that's why the latest designs for starship have diagonal thrusters 2/3 of the way up the rocket so they can stabilize the top heavy part of the rocket without having to control it from a high moment arm
williamDafoe··on A skeptic's take on beaming power to Earth from space
We don't have the tech to send astronauts to work on a geostationary or geosynchronous satellites. Its a high earth orbit (22,000 miles) and all our tech is for low earth orbit (shuttle, ISS, 400-800 miles) where the ship and station are protected by earth's electromagnetic field and the propellant requirements are much less ... To the best of my knowledge we have never repaired a geosynchronous or geostationary satellite..
williamDafoe··on IBM to buy HashiCorp in $6.4B deal
Also you should know that while the terraform language is okay (albeit a little too dogmatic in a functional programming sense for my tastes), the terraform cloud product (runners for terraform executions) is pretty terrible, slow, and overpriced, snatching defeat from the jaws of victory based on the terraform language.

This encouraged at least 4 companies to launch terraform-cloud-like products, and rather than compete and provide better service, Hashicorp responded by saying "take it or leave it, internet!" and they closed the open-source license on the interpreter (BUSL)... At my previous company we were driven away from terraform cloud and into the arms of env0 ... when it often takes 10 minutes for an execution to begin and you have no other executions in progress you realize that the terraform cloud SAAS product is just a total joke...

williamDafoe··on eC Programming Language
First commit in the bug system was in 2008.

https://www.ec-lang.org/mantis/view.php?id=1

To be ready for prime time an enhanced C language should be able to compile and run the Linux kernel correctly. Now that rust is being added to the Linux kernel this gets a lot harder, it must also port rust or compile rust.

williamDafoe··on System/360 – CHM Revolution
TLDR; System/360 was the first true family of architectures that spanned 1000x performance speedup, the smallest models were modest and heavily microcoded.

The Amdahl System/470 was dependent on IBM-compatible disk drives and IBM lost an anti-trust lawsuit in the late 1960s when they tried to deny cpu support contracts to customers using 3rd party disk drives.

Apple today is doing something quite similar by trying to deny repairs by 3rd party companies. IBM broke the law explicitly (tying) through verbal contracts whereas Apple is breaking the law implicitly using needless hardware crypto contracts ...

Thats why Steve Cook should lose the anti trust battle. Just watch.

williamDafoe··on Can Xerox's PARC find new life with SRI?
In 1970 Xerox snapped up most of the top engineers from dozens of silicon valley companies, and was roundly hated EVERYWHERE. Thus began a decade of great research but even greater hype ... But after 12 years of failing to capitalize on all the technologies invented at PARC and Office Systems Division - from 1983 to 1987 - Xerox experienced a mass exodus itself and many researchers in Computer Science joined Dec Systems Research Center or DEC Western research Lab (DEC SRC and DEC WRL).

The latter (DEC WRL) was credited with developing the DEC Alpha CPU; DEC SRC invented Altavista which was the #1 search engine until Google arrived.

I was an Office Systems Division engineer 1984-6 and watched the exodus unfold before I left for grad school. Overall DEC SRC/WRL didn't have as much impact as PARC; there is a time and place for everything and that kind of systems research - its time had passed ..

williamDafoe··on What Happens When a Fifteen Year Old Pumps and Dumps with a Net Profit of $800k? (2002)
No, Lewis argues that SEC is a protection racket! They make a bunch of rules and regulations with the input of Wall Street so that Wall Street can pump and dump legally!! Congress will not touch this radioactive protection racket because they are doing insider trading on legal changes which should also be illegal...
williamDafoe··on The Berkeley Software Distribution
The sword of damacles explanation of BSDi's ending is utter bullshit in this article. BSDi knew they were in direct competition with RedHat in the late 1990s. The President, Rob Kolstad, ran a very lean operation with only about 20 employees. Red Hat managed to IPO and was heavily capitalized. Some BSDi employees and one in particular, argued for an IPO and the particular guy from MIT guaranteed that with an IPO everyone would be rich in one year. The palace revolt worked, the MIT guy took over, Rob Kolstad was deposed, and the MIT guy bankrupted the company in just 1 year (record time). The pieces were sold off to Wind River, which was later absorbed into VxWorks, which finally cancelled development a few years later, and that was the end of BSD/OS or BSDi.

williamDafoe··on Nvidia bans using translation layers for CUDA software to run on other chips
They will lose in court. I am reminded of IBM trying to ban 3rd party disk drive makers for from making disks that fit the IBM disk interface in the 1960s. They lost, too. However, ZLUDA may have to do a clean room reimplementation of all of CUDA, like google did with their javascript reimplementation, however ...
williamDafoe··on Ryzen Z1's Tiny iGPU
Intel GPU performance was totally stagnant from Haswell (Iris Pto 5200) until Iris XE, from 2013-2019. AMD on the other hand was steadily building up their iGPUs, allowing the APUs to work together with external GPUs, and with the 5700g (which imho was a milestone) we finally had 30fps+ for all but the most brain-dead games (alan wake i'm looking at you!)
williamDafoe··on Figure out who's leaving the company: dump, diff, repeat
Epitaths is a Google thing. I had a friend at Qualcomm who wrote a script to sample the employee phonebook every morning before work so he'd know if he were laid off. We used "ph" from UIUC and the company strangely laid people off not by deleting them but instead by putting them into department 700, "The laid-off department".

The web UI allowed elaborate queries so the first time there was a big layoff the ph web page almost went down because everyone was querying to find out who was laid off. Management got mad at this but they really shouldn't have; its correct that you shouldn't work someplace that tries to hide attrition no matter what the source!

My friend never got put into dept 700 because i recruited him into Google a few years later ...

williamDafoe··on Thoughts on tech employment
In industry the chance you work on a project that actually makes money is probably something like 10% per job you have EVER had.

People making the actual money are truly rare. Most employees are doing speculative side projects, infrastructure of the company, field support, etc., but very few are on the critical path to a product that is actually cashflow positive ...

In my career of 30+ years i can claim i was making money in a profitable division that was cashflow positive for 5.75 years

williamDafoe··on Thoughts on tech employment
This is false the rockstar salaries in software started in the early 2010s with the rise of the worldwide software (SAAS) company many CS jobs started paying more than doctor or EE jobs even though the barriers to entry were lower. This directly coincided with the savings bubble from the first boomers - age 65 - finishing their peak savings years 2010 - 2022. This ZIRP savings bubble isn't coming back!

I've got news for you folks. This gravy train is not coming back ...

williamDafoe··on Thoughts on tech employment
In my experience, the USA is shitting on its entry-level engineers. I know 3 junior engineers unemployed 6 months after graduation, from top 20 to top 40 schools. They have 10 total internships among them.

One had a zoom, corp job with 24/7 hours they had no life and quit. One had their offer rescinded 4 weeks before start date. One had their position cancelled 60d after start date. All are now longterm unemployed with virtually no interviews.

Meanwhile overseas hiring and 85k H1B workers are flooding the job markets annually, its galling ...
