For a counterpoint, read Derek Lowe’s “Curcumin Will Waste Your Time” about all of the issues with Curcumin research: https://blogs.sciencemag.org/pipeline/archives/2017/01/12/cu... It’s also worth noting that Curcumin has been trialed for several conditions with no significant positive outcomes that I’m aware of.

I think the truth falls somewhere in the middle. Curcumin isn’t the broad-acting wonder drug that some of these articles claim. However, it doesn’t appear to be completely inert, either.

Be careful with marketing material from supplement vendors that focuses only on the positives. It’s not hard to find reports of Curcumin having various vague negative effects like reducing libido (apparently reverses several days after cessation) and other hard to pin down side effects.

Finally, it’s important to keep in mind that not all inflammation is bad. Inflammatory signaling plays an important role in many biological processes and it is entirely possible to overdue it with anti-inflammatories in ways that become counterproductive.

We offer usage-based billing at $0.10 per GB of memory hour. (https://www.pinecone.io/pricing/) For this app, our eng team knows for sure but I think the entire index is less than 1GB so it would be just $73/month if we keep it running 24/7.

Vector similarity search is new for most companies, so we want to make it very easy to try and test stuff out in production, without cost being a barrier. Even for larger volumes (40GB+) we offer volume and pre-commitment discounts.

I wonder what the general split is.

As a single person who does not have a family, working from home permanently sounds horrifically lonely. I only made it a month of solitude before I terminated my lease and moved back in with my parents (the rest of my siblings joined as well).

I also have ADHD, and sharing a space for work and play has been terrible for my ability to focus.

That being said, I totally understand the other viewpoint(s). I watched my father spend 3 hours in the car every day to commute to offices he hated for the majority of my childhood. He worked from home during the first few years after the dotcom crash, which was a wonderful opportunity for him to spend time with my siblings and I when we were young children.

My response to seeing that as a kid was making the decision that I would do whatever I could to avoid commuting. Since I'm still single, this has meant living in an apartment a short walk from where I work. Admittedly, I'm lucky in the sense that the office is in a relatively suburban setting. We're outside the city, so it's not city life but it's not suburban sprawl hell either.

Obviously the dynamic may change if I meet someone and have kids in the future and decide where the office is is not where we want to raise kids.

We don't gain anything from just having a knee-jerk reaction to the opposite solution. You just have a different set of happy and unhappy people.
There's a viral pandemic?

At the beginning of the pandemic, I wanted my child to go back to school ASAP, but then I reminded by a teacher friend that their health was important, too.

I believe no one should be forced to work if the health conditions are unsafe, why should teachers exempt form this? There are too many examples of teachers who did die from COVID-19.

Show HN: Superintendent, a desktop app - load CSV files, and write SQL
Hi HNers,

I'm Tanin and have built Superintendent.app which enables you to load (large) CSV files and write SQL on them. You can export the output back and/or make charts.

There are 2 problems working with CSVs using Excel:

1. Excel and Google Sheets have row/cell limits. When a CSV exceeds the row limit, you are kinda stuck. There are some workarounds (e.g. connecting Excel to Data Source), but they are difficult to setup.

2. Excel formula is also clumsy to use; this is especially for people already know SQL.

I'd claim that Excel formula is probably harder to master than SQL.

Superintendent.app is built, so I can work with CSV files more smoothly in my day job.

I'd love for you to try it and give me feedback. I hope this will be useful to you as it has been for me.

Thank you!

This take ignores the fact that frequently the underlying condition is known, it just doesn't have any cure known to science.

You've already been given the example of rheumatoid arthritis - another one is Crohn's, where "treating the symptoms" with anti-inflammatory treatments like infliximab or even just common-or-garden steroids vastly improves patient's quality of life. You can't tell these people to hold out until the researchers figure out how to cure the underlying condition, because that means consigning them to a life of painful intestinal scarring, blockages, fistulas, and ultimately surgery up to and including bowel resection.

Amazon was rebranded LeetCode for their "entrance level". FB was writing code in what appeared to be more Microsoft Word-like. (There was no console to check my work). But the conversations with actual humans was where things diverged. The systems design stuff for Amazon was very "we're looking to zing you". Facebook was definitely "hmmm, that's an interesting approach, have you considered....?" or "That sounds like it would work but, what if we...." That type of interviewing really makes one feel like they're part of a team instead of being completely alone. Amazon seemed to thrive on the "you're scared, alone, and you need to build a bloom filter and figure out an efficient hashing algorithm NOW." I realize this is probably not everyone's experience. I am not saying "Amazon sucks, all their interviews are bad" I was simply sharing my experience as it's what led me to remove my candidacy.

I think both efforts have been important and have benefitted each other. Nix has always had purity/reproducibility as tenets, but indeed it was Debian that got serious about it on a bit-for-bit basis, with changes to the compilers, tools like diffoscope, etc. The broader awareness and feasibility of reproducible builds then made it possible for Nix to finally realise the original design goal of a content-addressed rather than input-addressed store, where you don't need to actually sign your binary cache, but rather just sign a mapping between input hashes and content hashes.

Reviewing additional posts I don't think we seem any more alike than a random pick.
> manhandling /dev/nvme0 seems equally likely to corrupt data in the event of a power failure.

If we make the reasonable assumption that this subthread is discussing a server use case, then we can assume that the SSD is tolerant of power failures and has the capacitors necessary to finish any cached writes it has reported as complete. Thus, having fewer layers between the hardware and the application means there are fewer opportunities for some layer to lie to those above it about whether the data has made it to persistent storage.

Whether or not you're bypassing large parts of the operating system's IO stack, the application needs to have a clear idea of what data needs to be flushed to persistent storage at what times in order to properly survive unexpected power loss without unnecessary data loss or corruption.
Some of the issues were really difficult to tackle, like the linux kernel generating random hashes.

The last mile was done by removing the use of ruby (which uses some random tmp directories) from the final image. Asciidoctor (ruby) was replaced with asciidoc (python).

My favorite take on the Overton Window is this monologue from The Good Fight:

https://www.vulture.com/2019/04/the-good-fight-recap-season-...

Is it alright to hit a Nazi unprovoked? I was always taught never to throw the first punch, never to instigate. Defend, but don’t attack. But then I saw a video of the white nationalist Richard Spencer being punched in the face during an interview. I realized Spencer was in a pressed suit, wearing a tie, being interviewed like his opinion mattered — like it should be considered part of the conversation, like neo-Nazism is just one political point of view. And then I realized there’s no better way to show some speech is not equal. Some speech requires a more visceral response. It’s like Overton’s window — that’s the term for which ideas are tolerated in public discourse. Well, Overton’s window doesn’t mean shit unless it comes with some enforcement. So yeah, this is enforcement. It’s time to punch a few Nazis.

Certainly there's likely to be no reason that knock-offs can't be the same quality as, or better than, the original for much less price—but making the knock-offs appear to be the same quality while actually being lower quality is even cheaper still. As a counterfeiter, why wouldn't you make the cheaper product if no-one can tell the difference?

I am thinking here particularly of counterfeit chargers, which are designed to mimic the originals to comical extremes—so that you essentially wouldn't know without tearing them apart—but which are missing crucial safeguards that mean that they are much more prone to catch fire. If, as ClumsyPilot suggests (https://news.ycombinator.com/item?id=27573695), you are thinking only of fashion items, then it's probably less of an issue.

That was a nice read, thank you.

I was interested in how the author describes his father’s philosophy of wanting to let his children make up their own mind, then later seems to take no interest in the interest/life work of his child outside of how it related to the bubble of England. If I understand him, he is sad but understands and “gives up” his father at the end.

He obviously still very much cares about his father and his legacy, as he admits being underwhelmed with the minister’s eulogy and eight years later writes this tribute. It feels like a half-finished thought writing this out. I’m not sure there is a bigger lesson to be easily drawn other than people are complicated and the ways we are influenced and try to influence are hard to understand.

> Good luck to raise non IT capital in tech without patents

Again, this wouldn't be a problem if there were no patents
Between these sorts of experiments and the effects of the U.S. stimulus payments, I think we have a growing body of evidence indicating that some type of UBI is not only fully compatible with a traditional understanding of capitalism, but can actually enhance the positive effects of capitalism on the middle class (i.e. grow it, instead of shrinking it).

The problem, of course, is that the story around taxation will have to change dramatically. Think the endless debate over whether the 1% are paying their fair share is tiresome now? That's nothing compared to the upcoming fight to make any progress whatsoever on progressive tax rates at the high end of the spectrum in order to fund UBI.
> Let's not write this off as due to a less-effective vaccine until we find out whether or not this is in line with the expected effectiveness of that vaccine.

Sinovac does not have usable effectiveness data, due to the manner and place of its development. It is well-known internationally to be less effective than many other options.

> With each variant, nature gets another shot at obsoleting all existing vaccinations.

Please don't hyperbolize. "Obsoleting all existing vaccinations" means a new disease, not a variant. And every mutation is a tradeoff: if COVID-19 "starts over", it may well be much less virulent: less transmissible, or less deadly, or both.
Here’s an informative podcast episode on Nix with one of its maintainers, https://changelog.com/podcast/437.
In principle, diverse double-compiling merely increases the number of compilers the adversary needs to subvert. There are obvious practical concerns, of course, but frankly this raises the bar less than maintaining the backdoor across future versions of the same compiler did in the first place, since at least backdooring multiple contemporary compilers doesn't rely on guessing, well ahead of time, what change future people are going to make.

Critically, it shouldn't be taken as a demonstration that the toolchain is trustworthy unless you trust whoever's picking the compilers! This kind of ruins approaches based on having any particular outside organization certify certain compilers as "trusted".
I really worry about headlines like this. It can lead people to believe that the vaccine isn't worth getting because "SEE breakthrough!" Keeping the nuance in headlines for this matter is key for adoption.

One key unknown is whether the infection of those health workers was better/worse than the normal response post vaccine.

Breath through infections are expected. Vaccination isn't fool proof. The primary goal is herd immunity at the community level, and that those who do have a break through, their experience isn't nearly as bad without the vaccine.
Efficacy test of Sinovac show it has ~50% rate

Typically the Host and NAND interface have custom hardware. When the host issues a command, the hardware might validate it and queue up data to a buffer. On the NAND interface there might be a similar queue for NAND commands. You might have multiple queues for different priorities of operation. The error correct will also be in hardware. When you issues NAND reads and writes, the ECC will be checked or encoded. The rest of the FTL might all be in firmware. Perhaps a single core does everything. Or maybe its partitioned between two cores, one for the host related code and the other for the FTL related. Some companies have tried lots of cores, each with a dedicated state machine to handle some part of the operation. These can be complex to coordinate their operation and to debug. Some companies convert some of these state machines into custom hardware.

The only open SSD platform I've read about is http://openssd.io/ but I've never played with it. One of the challenges is the NAND manufacturers a lot of the critical documentation under an NDA these days. You really need that information to make a reliable SSD. When you learn how the internals of an SSD work, its a wonder that it retains data at all!

In terms of integrating SSD with the higher software level, I believe FusionIO was doing this in the past. They put the whole logical to physical mapping into the host memory.
This is fundamentally false. Witness the many conservation easement programs, or the agreements that have made possible many trail systems.

We UFS for content serving, and a mix of UFS and ZFS for boot/log/config filesystems.

We use UFS for content because we rely on zero-copy async sendfile for our high performance video serving data path. When using ZFS, sendfile is not async, and because ZFS uses ARC rather than the page cache, it requires a copy from ARC to network with ZFS, so its yet ready for our high performance workload.

We don't use RAID at all.
