And, refurbished business laptops tend to have better keyboards than consumer grade laptops, as well as a better build quality (generally speaking).

Don’t worry. It _is_ a neat trick, and it was nice to post complete instructions and benchmarks. And it wasn’t you who put it to the HN frontpage.

There’s a great paper from the group of Emery Berger, where they merge memory pages that become sparse. A kind of garbage collection for C and C++ languages. There’s also a good presentation about it on youtube. https://arxiv.org

If you’re curious to try arthouse/international cinema, give Mubi a try. There is less to choose from, but the selection rotates.

With respect to hallucinating, I never read about training LLM’s to say: “I don’t know” when they don’t know. Is that even researched?

Does this also apply to “supersparpreis” tickets? i occasionally use DB but I find the pricing options and rules confusing.

It’s a billion times integer modulus, summed. Div/mod is by far the slowest arithmetic instruction on a CPU, so it underestimates C/rust performance. I guess the author chose that to prevent the C compiler from optimizing the loop

These extremes exist, and GR predictions are better than Newton’s in those cases. Closest to home is mercury’s perihelion drift. We have observed black hole mergers, gravitational lensing, and GR is also an essential component in understand

The way I thought LCD/LED displays worked was by RGB filtering a uniform white backlight. Is it only this design that does fosforescence per subpixel? Sounds way more energy efficient.

It depends on the application. It’s the easiest way especially if you might encounter right to left script, CJK or emoji. It is worthwhile to cache the textures, most text does not change every frame. It is good enough for us.

I would argue it is conceivable that given enough time, a monkey or ape species can evolve that is intelligent enough to write Shakespeare’s full works.

The RAM is expandable as well… however I am curious how well the extra RAM performs. Part of the M-series performance gain is from having the RAM dies very close to the processor.

An example for those not in the know: to find a shortest route on a realworld map, an admissible heuristic would be that the minimum travel distance between two nodes will be a straight line. While examining options, A* takes this into acco

As an alternative to simulating latency: How about using a VPN service to test your website via Australia? I suppose that when it easier to do, it is more likely that people will actually do this test.

You’re right. I’ll read more carefully next time.

The author wonders why he does not see a memory footprint for the billions of objects, and conjectures they are stored in-line in the array. I suspect that it is actually achieved by the flyweight pattern, where copies of the same immutable

In such an alternative tech free universe, I guess most of us would be illiterate farmers.

I have tried the windows version 2 years ago. The site I copied was our on-prem issue tracker (fogbugz) that we replaced. HTTrack did not work because of too much javascript rendering, and I could not figure out how to make it login. What

It annoys me too, especially when the explanation is: “because RISC simpler so it is faster, duh”. However x64 is at disadvantage for instruction decoding (it’s difficult to decode multiple variable length instructions in parallel), and sec

Such an experiment was described in a science book I read as a kid. They dissolved oil in alcohol so as to measure a very small quantity of oil, and then a a knitting needle was used to stretch the oil film across a plastic container filled

How about applying the idea behind ESCROW: if you market hardware with software dependencies, you are required to provide the source to a trusted third party who will release/opensource it if you stop maintaining said software before t

On a motorway, 50 to 80 eurocents per kWh is what I often see. There is not enough competition. It is still cheaper than what you’d spend on fossil fuels. However, for day to day use you charge at home or at the office which is much cheape

Possibly they ask the text engine to render halfway two pixel lines. It will round up or down quite randomly when fp errors accumulate.

I have recently been wondering how it is possible that they can make features like that, and provide closed captions, but that they continue to insert ads halfway a speaker’s sentence.

The currently agreed protocol leads to < 10 transactions/sec. This can be improved, but 1000x will be challenging. https://en.wikipedia.org/wiki/Bitcoin_scalability_problem

What I think is worth knowing is that compute units in GPU’s also use SMT, usually at a level of 7 to 10 threads per CU. This helps to hide latency.
