svggrfgovgf··on George Goble died recently – known for first dual-CPU-Unix and fast BBQ lighting
Wrong George Goble - this is the computer scientist not the actor.
svggrfgovgf··on George Goble has died
Sorry to hear. I remember George running the EE PDP-11 as a time share system with Lear Siegler ADM-3A terminals at Purdue while the CS department (as part of the school of science) was using punch cards! The EE department had a room with 10 or so ADM-3As connected to a single PDP-11 that had a few 100KBs of RAM (512KB?).

(photos of ADM-3A at http://dunfield.classiccmp.org/altair/altair5.htm It has 24 lines of 80 characters with green text on black background plus some graphics characters which could be used to draw pictures.)

svggrfgovgf··on Why Los Angeles Stopped Repaving Its Streets
Here's a service in a medium sized town of Colorado:

"Large or Complex Projects - extensive curb modifications or custom installations can cost $1,200-$3,000 or more. These projects often involve additional planning, permits, or structural considerations, which can increase overall costs. Many jobs are completed within the lower part of this range.

Full Replacement - complete curb or sidewalk replacements typically start around $3,000 and can exceed $5,000 for larger, more involved projects. These are less common and usually reserved for significant repairs or upgrades, with most projects falling into the lower to mid portions of this range."

svggrfgovgf··on Ask HN: Is Mythical Man-Month still relevant in todays AI Vibe Coding world?

I think the idea had a lot of merit, but have never seen it in practice.

svggrfgovgf··on Blue Origin lands New Glenn rocket booster on second try
The two launches scheduled for today (Nov. 14th 2025) are both on the East coast and are scheduled to be within an hour (22:08 EST and 22:55 EST according to Spaceflight Now) from: Launch Complex 39A, Kennedy Space Center, Florida, and SLC-40, Cape Canaveral Space Force Station, Florida.

If those launches go on schedule, that will mean 4 launches (New Glenn, Atlas 5, and two Falcon 9s) in 31 hours from the Cape Canaveral area in Florida.

svggrfgovgf··on Democrats meet to discuss deal to reopen government
Yes, the republicans hold a majority in the Senate, but the Senate rules require 60 votes to stop debate on a bill (ie cloture). So, the Democratic members are holding up the CR by not voting for cloture.

Cloture is a very valuable tool for the minority in the Senate to keep the majority in check. Cloture is just a rule which can be changed by just a majority vote. I think it's a mistake for either party to do away with this rule. For example, during the Obama Administration, the Democratic members of the Senate changed the rules to allow federal judges to be approved with just majority vote. Then, during the first Trump Administration, the Republican members changed the rules to include supreme court judges, which lead to the current supreme court.

svggrfgovgf··on Newsom says CA will hold special election to combat Trump, TX redistricting
So, am I understanding this correctly?

TX has D's at 12/38s with proposed changes bringing D's to 7/38s (ie 31% to 18% D)

And in retaliation, CA wants R's to go down from 9/52's to 4/52's (ie 17% to 8% R)?

BTW, IL has R's at 3/17s (ie 18% R).

But, somehow, TX changing the D's percent to match CA's and IL's R percent is somehow beyond the pale?

svggrfgovgf··on The Difference Between Downloading and Streaming
>Since these streams are purely unidirectional, users don't have a way to notice that they're not literally live.

Depending on the delay, this can cause problems when switching from delayed streaming to real life. For example, watching the countdown on a rocket launch via streaming then going outside to watch the actual launch. Usually, for me, a few seconds delay is OK, because I can't see the rocket until about 30 seconds after liftoff due to trees. But when I have a better view of the launch pad the delay can become an issue.

svggrfgovgf··on Big slowdown in hiring here? June U.S. jobs report not showing it
I agree that the tech sector in general went through a lot of growth in the past 20 years, with a lot of new products.

But, I think the level of interest rates has a large impact on which projects are funded. With interest rates at zero (actually negative given inflation), almost anything is worth trying because you don't need a big return to come out ahead. And lots of those projects fail (never produce a product which can be sold), but while the projects are active people are employed. It's sort of like Venture Capital, but inside big companies: when interest rates are low, they run a lot of different riskier projects expecting some of them to pay off enough to make up for the failures.

When interest rates are higher, a project has to have a more certain return and a higher projected return in order to get funded. So weak projects are cancelled, or not started, people are laid off and hiring becomes really slow.

The mystery to me is why the rest of the economy didn't take off. Real estate did, and equities (stock market) did. But not the "main street" part of the economy or the industrial part of the economy. I think that since these parts of the economy did not take off, overall inflation remained relatively low.

svggrfgovgf··on Big slowdown in hiring here? June U.S. jobs report not showing it
I think the tech sector was pumped up by the long period of zero interest rates and falling back down since interest rates are up, have been up for a while, and looks like they will stay up longer than expected.

Meanwhile, most of the rest of the economy didn't benefit very much from the zero interest rates - it didn't grow like crazy with huge job demand and high wages. So, it isn't as affected as much by the higher interest rates. Which makes the overall job growth look stable even though the tech sector is hurting.

svggrfgovgf··on IRS Direct File to open to all 50 states and D.C. for 2025 tax season

Looks like exactly half and half, Democratic/Republican to me ...

But, who knows maybe next year ...

svggrfgovgf··on Consumers Hate 'Price Discrimination,' but They Sure Love a Discount
I think it's a matter of expectations. When I go to a restaurant, I'm OK knowing the price is X, but today (or right now due to whatever) the price is lower, but I don't want the "surprise" the price is X+Y when it's usually X due to something, e.g., shortage, high demand, or time of day.

If restaurants want to have time of day based pricing, I'd be OK with the base price being the highest price, with discounts during other parts of the day. For example, early bird specials have always been a thing (lower prices late in the afternoon before the evening rush). What I find objectionable is there being an unknown, unexpected, up charge based on anything, time of day, day of the week, phase of the moon, ... It's objectionable even when the up charge is mentioned when I arrive due to the overhead of having to go somewhere else.

svggrfgovgf··on Measles erupts in Florida school where 11% of kids are unvaccinated
Before you move, be sure to check out the local vaccination rate. For example, according to: https://www.ppic.org/blog/school-vaccination-rates-vary-acro...

>More than half of Oakland Unified’s 48 elementary schools and eight of its schools serving seventh graders are on the audit list for 2022-23. This includes Markham Elementary where 65% of the 66 kindergarten students were not fully vaccinated last school year. The school had the highest percentage of kindergartners in California’s traditional public schools — with over 20 students — who were not fully vaccinated.

>Of the 27 Oakland Unified elementary schools on the list, more than 20% of kindergarten students in a dozen schools did not have all the required vaccinations last school year.

May 30 2023 Bloomberg article:

Of course, the May 30 article is about the decline in interest rates over the last 8 centuries, and the current article is only talking about the next couple of decades, so both can be right.

svggrfgovgf··on U.S. has world’s highest rate of children living in single-parent households (2019)
> nobody goes into it wanting to go it alone

I think this is missing the point of the controversy. The argument at the time was that it was fine for women to chose to have a child without being married. It was not about "couples should stay together for the sake of the children".

The whole point of the TV show was "Murphy Brown was divorced, and then she decided it was fine to have a child." That is, if a single women wanted to have a child, she should. There was no need for her to first establish a working marriage first.
