If you capture the heat from the burning, e.g. to generate electricity, then that can save burning oil/gas/coal instead. Furthermore, the landfill will usually also generate gasses like methane, which need to be burned off too.

Nobody says they have no limitations. The question is are those limitation fundamental, i.e. can we expect improvement, say within a year.

No need for radical changes. def visit_bf(g): n, children = g yield n if children: iterators = [iter(visit_df(c)) for c in children] while iterators: try: yield next(iterators[0])

Well, the article says that the effect of the impact was much larger than the scientists expected. That doesn't really give a lot of confidence in how good we are at predicting these things.

I'm sorry, that second reference was actually for the 3.5ULP variant. The 1 ULP is here: https://github.com/shibatch/sleef/blob/master/src/libm/sleef...

One of the ways that the classics can be improved is not to take the analytic ideal coefficients and approximate them to the closest floating point number, but rather take those ideal coefficients as a starting point for a search of slightl

That's not just a good prediction—it is literally already happening right now!

Nothing on that list has been named that way by Euler himself of course.

That seems to be due to he microcontroller using its pins in duplex. There is indeed no radiation being emitted in that case, just the lamp and rotation. https://news.ycombinator.com/item?id=46979936

I saw that you used `float z;` to later use `z` instead of the constant `0.`. You can also apply that to get a zero vector: `vec3 y;` and use `y` in place of `p-p`. It seems that leaving the obsession behind some more can save another byte.

Another two bytes found (I think) (d==0.?K*.01*h:c-c) could become (d>0.?.0:.01)*K*h

Especially in HPC there are lots of workloads that do not benefit from SMT. Such workloads are almost always bottlenecked on either memory bandwidth or vector execution ports. These are exactly the resources that are shared between the si

Sort of niche indeed. In addition to needing SMT to get full performance, there were a lot of other small details you needed to get right on Xeon Phi to get close to the advertised performance. Think of AVX512 and the HBM. For practical ap

I'm not sure what the OS on the X32 (or the Midas M32 sister model for that matter) is from factory. The higher end Midas Pro consoles do definitely run on Linux though.

It is the performance win for similar looking results that I find improbable. For a box blur to look like gaussian blur, you would need multiple passes. Even though each pass is now O(1) instead of O(n) (with n the blur radius), due to ca

That link is not a box filter, as it still uses weights to approximate a gaussian convolution kernel. It just uses some special hardware to do less texture fetches. But that is a constant 2x improvement over the full 1D convolution, not t

Do browsers really use a box filter to approximate a gaussian blur? That seems implausible to me, as they produce pretty different looking blurs.
18.
by mkbosmans 2y ago
I noticed the blur only "sees" the underlying pixels directly below the glass surface. Any pixels outside that box, but within the blur radius do not get used in the gaussian filter. Probably the edge pixels are just repeated.

Why do you say a tritone substitution turns it in a II-bII-I? Can it be as easily said to be II-#I-I? In that case it would be C#.

This looks to me like actual correct usage of the term exponential. Surprisingly correct usage of that term is rare, even in technical writing. Let's say each dimensions added has a finite set of N possible values. Then for k dimension

by mkbosmans 2y ago
Yes, I think it is valid usage. Why do you think usage of the term _curse of dimensionality_ is different in ML?

Nothing requires an ESOP to skip on a separate retirement fund for employees and expect them to retire from their share of the investment. In the contrary, I expect the owners of an ESOP are very much in favor of having a well managed separ

It is not an unconstrained optimization problem. The constraints in which the company operates might result in a feasible region where even the most profitable point is still a net loss. Those constraints may of course be self-imposed, like

I do agree about the virtues of a resume that shows that it has been put together with care and attention. But don't forget that while coding, the IDE, compiler, or whatever will correct your spelling mistakes in a very short feedback

I think that is unique to Gitlab though. For example Azure DevOps will rebase the branch for you when completing a pull request.

The big difference between adding the first `== true` to `if (x)` and adding more is that for a bare `x` you need more context to know whether the expression inside the `if` is of boolean type or something that will implicitly be casted to

That's doable with the Python interface to GnuCash. I hacked together a little script that sucks out invoice data out of a register file and creates PDFs for new ones using a LaTeX template. My wife uses it for her business, mostly wit
