In case someone finds it interesting, kernel bypass also exposes hardware capabilities which can be used for optimization. A recent research attempts at leveraging NICs to accelerate data serialization https://www.sigops.org/s/conferences/hotos/2021/papers/hotos...

It is interesting to note how it compares to "choose" (also in Rust) in the benchmarks.

single character

    hck           1.494 ± 0.026s
    hck (no-mmap) 1.735 ± 0.004s
    choose        4.597 ± 0.016s

multi character

    hck           2.127 ± 0.004s
    hck (no-mmap) 2.467 ± 0.012s
    choose        3.266 ± 0.011s

The single pass optimization trick[1] seems to be helping a lot in single character case.

Of course, doing away with a pass is suppossed to give 2x, and I am wondering whether the regex constraint lead to this "side-effect".

> I've learned ... instead to simply say "I have a lot of experience with that technology" and leave it at that.

Shows Brendan's maturity.

I am not sure what should be the appropriate reaction or corrective measure in these situations. We should talk more about handling these unfair situations.

Someone else can become more successful building on top of one's open source project. On a resume, a top contributor and a minor contributor to open source project might have same weightage depending on how you present it - making the situation unfair for a person dedicatedly working on a single project (quality) vs minor contributor to multiple projects (quantity).

But deleting name and credits is wrong. An acknowledgement from the benefitting person (if not the recognition/reward) has far more positive impact on career than justifying to other's that your work was stolen.

It was a bit strange to read some of the initial negative comments. I see Brendan being a sport. I would argue that reading the story as a report against unknown persons at Sun makes more sense. I don't see much sense in blaming victim. And, in my opinion, the VIP had a good run but he isn't the bad guy here.

Even RSS (BJP cadres) affliated BKS questioned why the bills were passed in hurry.

They suggested changes to the bill and commented - "We have serious doubts whether the current bills will serve any purpose to the farmers and it appears more of a tool for the buyers rather than the farmers."

Modi's BJP is a power hungry party unlike anything I have seen. I doubt they care about anything (nation, economy, welfare).

The way it has been going on is that government announces something or passes some bill because they have to do something on a particular topic (say black money, taxes, Covid). However, they are incompetent or don't have the willingness or interest in actually carrying it out. So, these changes turn out to be catastrophic. They take toll on economy as well as anyone impacted because of the decision making.

Agriculture reforms are much needed in India. However, the government did it in hurry by-passing rules and without consulting farmers. I guess, they just want to do something so that they can let the marketing take care of the rest (that the goverment has done something for farmers - doesn't matter what or irrespective of whether it really helps them).

With these bills, the concern is that it will let private players take over and exploit farmers because of insufficient provisions to take care of farmers' interest. And then nobody will care (very much a risk because no one raises voice of oppressed which might show government in bad light because of the sold-out media). And the government will push narrative that they did the "reforms" (backed by fake data which is a hallmark of this government).

You are not too off from what has already been stated in the link, just that you cherry-picked it. Regarding criticism, Modi himself tweeted that "criticism makes democracy stronger"[1] so why should anyone get blacked out!

I am talking about Justice Loya [1].

By the way, the govt has been very active in making sure that they have their loyal representatives in bureaucracy as well as in judiciary. Recently, the Supreme Court convicted a prominent lawyer for a tweet criticizing them [2]. It is very easy for them to dismiss cases which might show them in bad light. Media has no independence either. Eg. the case of Punya Prasun Bajpai [3] who's show was blacked out and eventually cancelled because it was critical of Modi.

Since the title mentions the idea as well as the govt, let me add that while the idea is excellent, the current (Modi) govt is incompetent when it comes to execution, or may be has some other interests. Examples - failed demonetization, poor implementation of Goods and Services Tax (GST), failed Covid-19 lockdown. Most of what the govt does benefits select corporates (eg. rise of Jio). Interestingly, Paytm benefited the most during demonetization (2016) which is mentioned in the article and might have catalyzed the idea. The important part to notice is that demonetization was aimed at wiping out black money, GST was supposed to improve taxation, Covid-19 lockdown was supposed to dampen the long-term effect. However, these steps which were supposed to improve economy turned out to be counter-productive. Due to the poor or misdirected execution, India's economic is tanking down. So, although self-dependence is the stated goal, I am not sure where it will land. Moreover, the authoritarian tendencies don't help either. They are known to blackout journalists, assassinate lawyer, conduct media trials and put anyone speaking against them in jail. They will be a bigger bully than Google/Apple and pose a bigger risk to privacy.

Used `checkstyle` 4 years ago to improve the quality of code. Has neat XML based rules and good IDE support. See if it fits your use-case.

'sqlite3VdbeMemRelease' doesn't alter the value of 'c' but may alter the value of 'pmem->flags' which is what the compiler replaced 'c' with.

from the post by Dr. Richard Hipp "From the -S output, it looks like Clang-11.0.0 is compiling these three lines as if there were written as:"

      sqlite3VdbeMemRelease(pMem);
      pMem->flags = MEM_Str|MEM_Term|(pMem->flags&(MEM_AffMask|MEM_Subtype));

Another fix (one mentioned in detailed release notes) is where asinh(-0.0) used to return 0.0

These unexpected behaviours are tough to nail down when one is trying to get the code/setup working. Really appreciate the time these fixes potentially save for future users. The complex nature probably also hints at maturity of Rust codebase.

Completely agree. That ways discussion would be at one place and front page won't be hogged with possible duplicates.

Right now the other post is enjoying more attention and has meaningful engaging discussion. Requesting @dang to remove this (21473257) from front page and possibly tag the other one (21473259) with 1.39.0 release.
