Comment Re:Should have (Score 3, Interesting) 112

Go back and get them to do this 8 years ago? Just looked it up- in Texas at least, you need 4000 hours of experience as an apprentice to get a tradesman license, 8000 additional hours to get a journeyman's license, and 8000 more hours to get a master plumber's license. You can become a physician in that time. Yeah, as an apprentice, you do get paid, but you're also doing the carpiest jobs available.

Still, the hours are actual work hours- in the trades, few are actually employed 2000 hr/year. It is all hourly.

Over on reddit, I saw another post that mentioned to become a journeyman plumber, it takes 10,000 work hours, and 1000 classroom hours.

An SQL query is only as good as the data. A huge amount of the data is still not in a form that can be queried.

Many of the records involved easily go back 40 years. The solution is not to say "it's broken" - the solution has to both do what is necessary now (for those applying for entitlements [the things they EARNED]) while also fixing it for those that retire in the future.

Like the reforms to the FAA: we need to fix a running engine, not just stop it with no clear plans to restart it immediately.

Comment Their CPU strategy lost (Score 3, Interesting) 120

(Purely technical perspective, don't really know much about the business side.)

I may have some good insight here- worked for a major computer manufacturer in networking. For at least 20+ years (30?), their strategy has been to pull as much computing back in to the CPU as possible. There are some good reasons- high bandwidth, low latency. (and problems, heat and analog performance). They kinda did a "pshaw" with all the video stuff, and maybe a half-hearted attempt, but when the algorithms broke out into the GPU, they were in trouble.

Overall, I expected that the concentration on the CPU itself was the downfall. Yes, Intel is active in many other technology areas, but their focus on all these areas is that they are peripherals of the CPU, connected as close as possible to the CPU. When the peripheral does not push its work to the CPU, it wasn't prioritized.

Government contracts of the size that Boeing gets (~30% of annual revenue) do NOT in any way reward mediocrity- they reward predictability of performance, and try to make costs predictable, but performance is paramount. No company in the production stage gets a contract that is not already well reviewed for the costs involved (except, perhaps when bribery is involved) and that it can be done at that level, though not everything is so predictable. I worked in government contracting, and we had 2 types "firm fixed price" and "cost plus" - it was far more difficult to get a cost plus contract, as they were more open ended.

As to "Government Insiders" and pet projects, IME those were all elected officials or served at the whim of elected officials.

Comment Re:RTFS! Is to be used in FORKLIFTS, not "vehicles (Score 1) 77

Very hard to use an ICE forklift in an air conditioned area. Guidelines I've read suggest an air exchange of 5,000 cubic feet per minute per propane forklift, 8,000 per gasoline forklift. Considering the carp that Amazon has gone through with reports of high temperatures in their facilities, It would be pretty hard to have "climate controlled" facilities (their words) and combustion forklifts (and these forklifts are fuel cell).

Comment Not combustion. These are fuel cells. (Score 1) 77

The article is not accurate when it mentions "combustion" - these are fuel cell forklifts. Hydrogen and Oxygen from the air in, water + electricity (and some heat) out.

Fuel cells are a pretty decent option (when you're not generating the Hydrogen from fossil fuels), since the working temperatures are far lower than combustion. When you burn a fuel in air, the high temperatures lead to reactions with the Nitrogen, producing NOX gasses.

Comment Re:of course it comes pre-mixed with oxygen (Score 1) 77

It isn't ignition- the article is not accurate when it mentions "combustion" - these are fuel cell forklifts. Hydrogen and oxygen from the air in, water + electricity (and some heat) out.

To the point of flammability, Hydrogen is way less dense than those other flammable gasses, and dissipates (goes up) far faster. It is easy to ignite, but it does not sink and pool.

The speeds involved kinda make the "module" idea impossible. The interconnect winds up being far larger and expensive than everything else. High speed connectors that can reliably plug and unplug many times are really difficult to make.

The $2000 radio of 20 years ago would have been much more expensive, larger, and power hungry, if it was built with interchangeable parts.

Comment 2005-2020 Dell Power Edge 420 SC (Score 1) 288

I worked at Dell at the time (and employee discounts were limited and NOT great, so this was *my* money)- the 420SC, PowerEdge "value line" of servers (internal code names for that generation were Ford cars, imagine the cheapest Ford in the early 2000s). The server was mostly a rebadged desktop, to make it a very inexpensive machine, but ended up being quite different from the desktop. Still, the design was to put good, but inexpensive, parts together. Minimize the initial BOM price, but also minimize the add on service "tax" that warranty implies.[***]

My job was in the server networking group- mostly hardware related, making reference designs, testing to the IEEE spec, etc. I was impressed that this was the first of the "cheap" servers that would do "wire speed" on gigabit Ethernet. Since it was PCIe, the bus could actually handle everything the network could throw at it (process it... maybe?). Add to that, it was capable of running ECC DRAM.

Ran it as my home network server- NFS/SAMBA, local DNS, DHCP, and even as a public web/DNS/SMTP/Majordomo server for a time (when I could get a static IP) for my personal domain until 2012 (?) or so. Stopped when it just got to be too much work and expense (and cloud hosting services got somewhat reasonably priced), and SQUIRREL!

I was quite impressed by the uptime- I am 100% sure that having ECC was the largest influence on reliability. Had a few drives fail, and maybe a DRAM stick. Same processor, fans, and PSU for the entire time. I decommissioned it when I realized a Raspberry Pi (when you could actually get one!) would do as much/more. If only that architecture supported ECC DRAM.

[***]: when calculating the price for any product with a warranty, the expected cost is added to the overall price-tag. The warranty is NEVER "free."
