Apparently, it worked too well in Lockheed Martin opinion.

>Temperatures on re-entry “were lower than we expected” on EFT-1, Hawes told reporters here during Lockheed Martin’s annual media day.

>That data supports a Lockheed Martin proposal to scrap the current heat-shield design, which features a 5-meter-diameter honeycombed frame, in favor of an alternative composed of rectangular heat-resistant tiles glued together with a silicone-based adhesive, Hawes said.

By that logic, was ISS obsoleted by Skylab?

>They size the zram device to 100% of your physical RAM, capped at 8GB. You may be wondering how that makes any sense at all – how can one have a swap device that's potentially the entire size of one's RAM?

zram size applies to uncompressed data, real usage is dynamically growing (plus static bookkeeping). Most memory compresses well, so you probably want to have zram device size even larger than physical RAM.

Well clearly there is use for these - how do you distinguish what you are accessing in smart-pointer-like types.

It might be challenging to show "substantial similarity" between assembly and C++ codebase after 20 years of evolution.

On the other hand I heard that one shouldn't trim leads after soldering as it might crack solder joints...

In Poland, ticket enforcement from speed cameras is about 50% (because if you don't accept it voluntarily, they need to file court case and burden of proof is on the government here, as with any other criminal case).

The trouble with Solvespace is that using it quickly turns into randomly nudging points in hope to avoid kernel failures. Lately I have been using Dune 3D which uses much more reliable kernel.

>In the latter case, even when the compiler chooses to inline the function, it also emits code for an independent instance of the function, because the function is public and it may be called from another file.

Not in standard C. "inline" function provides implementation for usage iff compiler decides to inline the call. If it does decide not to inline, it will emit call to external symbol that needs to be defined in different TU (otherwise you will get errors at link time).

Is it? 4-9% of unsold portion seems reasonable. Unless they actually mean 4-9% of all manufactured.

https://www.eea.europa.eu/en/analysis/publications/the-destr...

Oh, it's really percentage of all produced. Weird that they worded it in a way that makes their argument weaker.

>Based on available studies, an estimated 4-9% of all textile products put on the market in Europe are destroyed before use, amounting to between 264,000 and 594,000 tonnes of textiles destroyed each year.

I read both and I think rewrite is much better. Though this is specifically because I didn't like the ghosts in the second half of original.

It seems to me that either you want to allow for contraction everywhere, or not all. Allowing it only sometimes is worst of both worlds.

Because it's not about security, and bank doesn't own my device. If it was, I should be able to supply the bank my own attestation keys.
