9659··on Ask HN: Advice for Imminent Pip?
Don't waste your time comparing your productivity with others. What you think or what the real facts are do not matter. This train has left the station.

Focus on getting off the train.

9659··on Living Computers Museum to permanently close, auction vintage items
Personal collections are for enjoyment, not investment.

I liquidated some of my fathers things for effectively nothing. That he spent decades acquiring.

9659··on GCC's new fortification level: The gains and costs (2022)
This brings up a question. I think we can all agree that detecting an overrun shows a fault in the system. But does it create an error?

Could this could be changed to where the overflow does not cause an abort; rather the next read of that location, without a corresponding legal write causes the abort. A buffer overrun does not mean the answer is wrong, but the use of memory that was overrun will.

In that case, production or not, you would want an abort. The answer is wrong!

(Perhaps this makes no sense. If so, sorry, the idea just came to me after reading the article.)

9659··on Unschooling Is the Parenting Trend That's Pissing Everyone Off
do it like every other business. double it. that leaves you with 1/2 a million profit per classroom, per year. ripe for disruption!

but, that 1 to 32 might not be accurate. special ed is required by law, and the ratio in those classes are probably 5 students, 1 teacher.

and then we have the 'additional teachers'. in middle school you might have a gifted and talented teacher, a music teacher, and maybe a PE teacher. they would not count as overhead since they are direct instructional.

and, and, and. my point is your model is too simple.

in the end you will probably find that the overhead is 400%, and it is there because of principals, assistant principals, curriculum specialists, behavioral interventionists, speech therapists and...

we have allocated dealing with a lot of problems to the public schools system, and it costs a lot of money.

what is reasonable is determined by your local school board. they levy the taxes, they spend the money.

9659··on What everyone gets wrong about the 2015 Ashley Madison scandal
Those two acts have the same direction, but very different magnitudes.
9659··on Julian Assange has reached a plea deal with the U.S., allowing him to go free
heard that he has a tax issue that he will be hit with as soon as he returns to the mother country.
9659··on Astronauts stranded, multiple issues w Starliner – return flight window closing
rather kill the program than lose a couple of astronauts. my opinion, Boeing stockholders may feel differently.
9659··on Continuous Software Delivery for National Security Missions
Is this a joke? I cannot tell.
9659··on B-Trees Require Fewer Comparisons Than Balanced Binary Search Trees
Just because it was first discovered 15 years ago, does not mean it wasn't still a good idea.

Keep on thinking. You never know what else you will come up with.

9659··on Spending 3 months investigating a 7-year old bug and fixing it in 1 line of code
If you are honest, it may not even alternate. Both feelings can exist at the same time.
9659··on Spending 3 months investigating a 7-year old bug and fixing it in 1 line of code
$50 for a one off thing, for a gym buddy is fine. in the blue collar world, that would be a 'case of beer' for helping me out.

But in business, you need to charge an honest / fair amount. (sure, sometimes that 1 hour bug fix had $100K of 'value', but we could argue about honest / fair).

You mention being an employee at $100K a year. Double that, gives you a contractor rate of $100 an hour. That is the floor of what you should be asking floor; as in the absolute lowest. Another $50 or $100 an hour is still fair and honest in todays economy.

9659··on PaperTapeReader: A DIY reader for vintage 8-bit paper tapes
Absolutely.

At one time in my life I spent many hours every week decoding MS1553 traffic. basically, 4 digit hex numbers.

after about 6 months i was able to subtract in hex. and add. in my head. without writing anything down.

some parameters where in 'BAMS' (look it up, it is cool). could look at 2 4 digit hex numbers and understand the magnitude of the angle differences without thinking about it.

today, i need a calculator for anything...

or, feed the cards into a reader.

put them in a file.

sort the file.

send the file to a cardpunch.

recycle the original card deck

i don't remember how to do this on a CDC mainframe, but at one time in my life it would only have taken 15 minutes. of which 14 minutes would be waiting for my job to run.

9659··on PaperTapeReader: A DIY reader for vintage 8-bit paper tapes
my experience was with an ASR-33. The paper was not oiled and it did not travel all that fast through the reader. yes, i used ordinary scotch tape. how it was done:

punch your 'patch'. make sure there are a couple of feet of nothing before and after (no data, just paper with the sprocket holes in it).

cut into the 'master' tape at the right point.

tape in your patch.

duplicate the 'master' to make a new master. the ASR-33 had a mode where it would duplicate a tape.

9659··on PaperTapeReader: A DIY reader for vintage 8-bit paper tapes
Nice project. I like the idea of using the fill of the input buffer to control the motor speed. Excellent.

For those that never have used paper tape, it had one big advantage. You could edit it. Using tape and a pair of scissors.

Storing more than 1K or 2K in a roll becomes unwieldy to store and carry around. And do not drop it so it comes unrolled !!

9659··on The number of CS grads who don't even know basic Git commands is astounding
I have worked with people that have a command of a given programming language, and algorithms such that it appears to be magic to me. (C++ is common for this problem).

The readability problems may be the reader.

9659··on The number of CS grads who don't even know basic Git commands is astounding
The two degrees are distinct and accredited differently. One is engineering, the other is computing science.
9659··on The number of CS grads who don't even know basic Git commands is astounding
It could be they are working at a level higher than you understand.

Not being snarky, but the elite schools are significantly advanced.

Imagine learning algorithms from Knuth (yes, I know he hasn't taught undergraduates in 50 years). Looking at the results after being taught by Dr. Smith at Generic State University, you might be unable to recognize the genius.

9659··on SGI Internal Memo: IRIX 5.1 40% slower than 4.0 (1993)
History repeats itself. Note the agonizing over memory. They were targeting a 16 MB machine.

We have the same problem. Ever try running linux on a 4GB machine? It naturally desires 16 GB nowdays.

9659··on Fast linked lists
if the value really is 0.01%, then the education pipeline needs to be revised. 'blue collar' programmer positions should be the majority.

9659··on AM radio law opposed by tech and auto industries is close to passing
modulation does not matter for range. however FM requires a greater signal strength to convey the information. if you are trying for distance, AM works with less recovered signal.

exclusive of digital modes, the most distance effective signal is CW. unmodulated signal, on or off.

9659··on Bayer is getting rid of bosses and asking staff to ‘self-organize’
a time honored and tested management philosophy.
9659··on Death and typos: my six years screening online obituary comments
"The Obituary Show" was probably a big money maker. Sponsored by a funeral home, I expect. Great place to be heard by your future customers.
9659··on The Lost Worlds of Telnet (2019)
I used to read 73 and QST cover to cover. Every article, every ad. Then came the "Computer Shopper". Too big to read.
9659··on Boom announces successful flight of XB-1 demonstrator aircraft
Maybe not a 'good time', but a safe one. Commercial airliners have standby instruments and a VHF radio that works on a battery. Which is all you need to get it on the ground in one piece.
9659··on United Airlines tells Boeing to stop building Max 10s and to switch to max 9s
Sure. But they would not be cost effective.

Building ~ 160 F-35's a year, with special alloys and coatings is a lot different than building 200 commercial aircraft, made out of aluminum and rivets.

Like Haskell vs. Cobol.

9659··on Pilot of Boeing flight says he lost control after instrument failure
Of the three, Manning and Winner, have been convicted (or pleaded) in a court of law, been sentenced to confinement, and served the time.

As far as I am concerned, those two have paid in full what they owe our society. Leave them be.

9659··on Ask HN: Which skills are least likely to be replaced by AI?
The military is reluctant to take the decision to kill someone out of human control.

The AI may fly the plane, but the trigger is squeezed by a human.

9659··on The worst possible way to be rejected for a job
I like getting a phone call. Zoom call would be OK, too. In fact, an e-mail would be good.

Even without feedback, the job hunter can scratch that opportunity off of the list, and move on looking for something else.

Yes, it stings. But the finality of it allows you to move forward with your life.
