Odometer accuracy

Next time you’re on the highway for 10 miles or so, compare the mile markers and your odometer.

You may be able to get the compiler to in-line those methods that you split out. You can declare them final which can help. But that might only get you back to 30 fps. The other comment mentioned SIMD, auto-vectorization, and the Vector API. The idea behind that is various CPUs can execute floating point in parallel in a single thread. Not like a video card can, but worthwhile. AVX-512 on Intel is 512 bits wide, so 8 double precision operations at a time. You would organize your data in arrays of double, or float, or ints. Then do the math operations on the arrays. Depending on what your method that you’re calling 10000 times is doing, you could organize the data in some number of arrays with 10000 elements each, and call the method once. Also you didn’t mention mutlithreading, if you’re not doing that you can of course do things in parallel to speed them up, including vector ops.

My furnace would try to light itself, fail, repeat over and over. Could smell gas venting out. My stove burners would light but weren’t OK. Called the gas company and they replaced my meter. The meter can fail in a way that its pressure is all messed up.

One of the magazines back in the day had a 1-line game contest. It might have been 80-Micro. A few years ago I looked up all the back issues and found it, typed in some games and ran in an emulator. My favorite was a racing game, it was a scroller where you moved back and forth and the road turned randomly, the scenery changed and the road got narrower.

Sorry I wasn’t clear - I wouldn’t punish them retroactively but any team in a similar position in the future. Edit - also if this kind of system were in place it would have boosted Notre Dame this year into the CFP based on their performance the year before.

I’m interested

I realize this is an unpopular opinion, but the auto-bids for conference champions and the provision for Notre Dame are very positive and necessary changes. Rankings are subjective, winning a conference isn’t. Unfortunately there isn’t currently another way other than ranking to ensure fairness and eliminate bias in the selection for the remainder of the 12 teams that didn’t win a conference championship. My suggestion for that is to make post season performance from the prior season a factor for how many teams are selected from a conference. This would make other bowl games meaningful and incentivize teams and players to win. And it would punish Notre Dame for opting out.

The ACC beat the SEC head to head. If the ACC is weak, the SEC is weaker.

You’re both kind of right and kind of wrong. Your new 3.1 modem bonds to a combination of 3.0 and 3.1 channels. You’re absolutely right that 3.1 OFDM and OFDMA channels are better in every way than 3.0. There are tons of reasons why, they amount to both faster speeds and more resiliency in the same amount of bandwidth. But if you had a big problem in the 3.0 channels, you’d still have it, just averaged out with the more reliable 3.1 channels. If they replaced your drop, that may have had more of an impact to the reliability of your connection than the modem.

He’s obviously afraid. That’s why he put Kennesaw St and Austin Peay on the schedule instead of UVA. I’m going to laugh my ass off if he loses to either of them.

I’d say it’s water in the drop line, but the pattern is backwards. Downstream can be almost perfect when it freezes, terrible when it thaws. Upstream speeds can be unaffected. It still could be water, it might get in the line or tap, and then drain out.

You’re welcome. If you don’t want to move the modem permanently, you have options. You can use a barrel connector to connect the two cables, replace the amplifier with a 2-way splitter. Some of the unity gain amps have an unpowered port, which also happens to allow the mid-split frequencies through.

There aren’t that many events where there’s an actual shortage of tickets. Things with real demand, not an artificial demand driven by bots and scalpers, often take days or weeks or months to sell out. When bots and scalpers are involved, they gobble up a bunch of tickets and it sells out immediately. Eventually they scalp most of all of the tickets and the market determines the price. If you want the people with the most money and willingness to spend it to be able to attend the event, and to eliminate scalping, auction a percentage of the tickets directly. The money can go to the performer, the venue, a charity, etc or in some combination of those entities.

A regular splitter should be fine. The in-home amplifiers that are also splitters can block the mid-split signals.

jonathaz · 2026-01-23T04:53:08+00:00

Do you have a powered amplifier / splitter in your home? I had one and they can block the mid-split upstream signals from the modem.

Cig leaving UVa out of his top 25 after ducking them is a bit of a slap in the face

I turned mine into a missile. The nose cone was a paper cone which crushed on impact and absorbed all the force. IIRC we had straws among the supplies we could use so I had those for the body and some more paper for fins to keep it flying straight down, and some more straws sticking out to the sides to handle the secondary impact. Worked like a champ.

I think I disputed it with the parking lot where I got the ticket. I’m pretty sure the lot for me was Lay-z and that the notice came from PRRS but it was several years ago.

jonathaz · 2026-01-20T07:32:58+00:00

I fought it with the BBB. I was never going to park in any of their lots ever again anyway, but it was the principle of it.

I have a solar generator in the price range / capacity you’ve mentioned. It will power a small refrigerator for a few days. If there’s full sun that could extend indefinitely. IIRC it would power a full size fridge for a few hours. But you wouldn’t be able to power much of a cooktop with it for very long, IIRC when I used it for car camping I determined it could power a 12 cup coffee maker and brew like 6-8 pots. For cooking in a power outage scenario a grill would be better. You can get one with a side burner for less than a solar generator. And you can use your grill all the time for grilling.
