We keep master to be the version of the code in production. So any pull request that has to be merged to production is code reviewed, automatically deployed to production via spinnaker in a canary, blue-greened across production, and with splunk and new relic monitoring we know if the code in the PR affects production, and if it fails after 15 minutes in production we rollback the code all the way (back in stg\dev too). One of the key things we leverage is feature flagging and ALL code is behind feature flags using launch darkly...so we do controlled exposure of the code (enabling the feature) for specific users\segments of our population until we enable it for all users.

Biggest issue is the delay between code being deployed and enabled in production and users actually using the feature which allows us to get meaningful metrics on the viability of the feature.

I know the honey I eat is real because it comes from the bees that live downstream of my driveway. My beekeeper tells me they have the best flavor of any of his hives, probably because it is in the middle of a complex beaver habitat.

Depends. My commute home from my office has a 6km of a three-lane road and then a single traffic light. The road never gets backed up more than a couple km from the traffic light, so even dropping it to a single lane wouldn't make any real difference to the throughput. The speed you drive on the three-lane road also makes no real difference to the throughput as long as you get the same amount of cars through the traffic light at each cycle.

A familiar pain to me as well. My solution, at least for software I only use periodically and does everything I want it to, is to just not update it. This is especially true for the times when a company offers a free home version and a paid professional version, and over time slowly strips features from the home version.

Hey, send me an email (should be in my profile, or easy to guess: it's a gmail account) and I'll see what I can dig up. :)

I've admittedly been pretty terrible about actually publishing... But definitely have notes and slide decks that could probably be put together into Something.
The German Post designed the Streetscooter a while back which is an electric delivery van. They also claim "zero fine dust driving". But how does that work? It is quite hard to have a fully closed system so no particles can escape. Well, their solution is quite clever: They are filtering the air in general, so can also consume particles emitted from other cars, even when the vehicle is not moving. So they could even get to net negative fine dust emissions :)

I only buy honey that has crystallized a bit. AFAIK only natural honey does this. It's insane that people don't like this, so sellers are heating the honey to stop the crystallization.
Ok. But honestly, the other 69% of Americans that don't live in California don't get this. Not only that, but it can somehow vary by employer.

Other places simply have it for everyone, and a union negotiation won't take away the safety net, as it is a right. It can only add benefits to the minimum.

I think Protobuf fundamentally can't achieve zero-copy parsing without changing the underlying encoding. That said, zero-copy parsing only provides a significant real-world benefit in certain use cases. For the use case of RPC over a network -- especially over the internet -- zero-copy parsing has minimal benefit. The places where zero-copy parsing can be a big win are when it means you can mmap() a very large file, or for IPC in shared memory.

On the other hand, Promise Pipelining -- and, more generally, object-capability RPC -- could definitely be added to gRPC. In fact, the very first iteration of Cap'n Proto was a Protobuf-based RPC system that used the same service definition syntax that gRPC now uses. "Cap'n Proto" at the time meant "capabilities and protobuf". (That version of the project was short-lived and shares no code at all with the current Cap'n Proto.)

However, I don't think gRPC is likely to add ocaps unless and until the model proves itself by gaining wide popularity elsewhere. It doesn't make sense for gRPC to take the risk of adding a big, new, experimental feature which they'll be forced to support forever when the demand hasn't been proven yet. Ocaps are gaining a lot of popularity lately (with major new tech like Fuschia and WASI being capability-based) but I think there's still further to go before it would make sense for gRPC to adopt it.

they're also measuring vastly more "emissions" over the life of the tire than there is material in the tires, so it appears that what they're actually measuring is the asphalt dust that's being created by the interaction between the road surface and the tire - a longer-wearing tire would presumably be harder material and cause slightly more road wear as a trade-off to less tire wear, so if they had actually tested it a higher-quality tire might cause more of what they're classing as emissions.

but you can't really make an assumption either way when you've only measured on a sample size of one.

I'm on a HSA plan with an absurd deductible. The crazy thing is that the HSA plan is still cheaper given that my family does not have any critical event in the next three years. HSA was a great idea (one of my employer had low premium + low deductible + good HSA account subsidy). But way too many employers and insurance company abuse it where people are afraid of using their insurance because of the out of pocket cost.
While the adulteration problems appear to be real, this reporter goes out of their way to exaggerate the problem. They diss Whole Foods honey for not being raw, when it's...not labeled as raw. Whole Foods certainly does sell some honey labeled as raw, but you pay more for it.
That the Wal-Mart sample wasn’t adulterated isn’t surprising at all. Wal-Mart is notoriously bossy and intrusive to its suppliers; it’s sometimes said that if you sell to Wal-Mart, they end up knowing your business better than you do.

This is the perfect opportunity to link people to Robert Heineken’s story: the Roads Must Roll. In it, there are a series of road towns, where roads are more like moving sidewalks.

My issue with that is how your control comes from the front tire on bicycles. Anytime I have a tire issue the front tire gets the newest rubber. Rotating tires is just spreading the wear and reduced traction to your steering tire.
> The small issue with the append trick is that is that it assumes the reader application will now respect the new format and not open insecure parts... which might not be fully implemented in all cases and is reader specific.

Yes, note my original emphasised use of the term "supposed to".

> Fully sanitizing the PDF yields better guarantees of security at the cost of lost functionality.

Indeed it's a tradeoff. But if you're willing to throw away the features which this extreme sanitization would trample across and have any ability to design PDF out of your system, you're probably better off not using PDF at all in favour of some straightforward image format.
> ...I wouldn't put much weight in the specific wording of job descriptions...

Agreed, and normally I wouldn't care as much. But I'm actively look for work right now...so to invest time and effort only to be met with rejection and disappointment(because of such mismatches), it gets frustrating really fast.

I was under the impression that most of what we consider rural populations are left overs from transportation arteries and extraction industries that popped all over the country during the industrial revolution. I thought the actual number of farmers is vanishingly small and I doubt it takes an entire 3% of the country to support a mostly automated industry.

It's not a topic I've seen well quantified.
In countries where sanitation is an issue will the infection rate ever slow and when people from countries who have it controlled travel to those countries does it restart ?

If you drive less and have separate summer/winter tires, it has the odd side-effect of making long-wear tires not worthwhile, as the life of the tread depth will exceed the life of the rubber due to age.
Oh no. I blame you for this.
I think there are fair questions about the long term sustainability of such safety nets and what place countries without such nets have in propping these places up.

Ask HN: How do I learn C properly?
I have 15+ years of experience in many languages: javascript, python, go, etc.

I can write C, but I'm not confident I'm doing it the right way. There are now decades of forums and blogs I can search through, but I'd love to have a single, clean, clear source of truth for recommendations on how to write C code.

I've started reading "Modern C" by Jens Gustedt. I'm not sure if this is the closest to a modern source of truth.

Note, I'd like my C code to work on Windows, which possibly restricts the "right way" to features provided by C89. But again, I'm not sure, the internet is super clear on this.

Thanks for the tips!
Google Got Its Employees to Eat Their Vegetables
I have a M.Sc in maths. I can derive the algorithm to solve a 2x2 linear system in the reals or the complex numbers, but I’m not sure I know how to do that properly in IEEE floats or doubles.

In particular, I wonder whether ill-conditioned edge cases (https://en.wikipedia.org/wiki/Condition_number) might need special-casing.

Having said that, I’m not convinced I could easily judge the quality of a third party solution, find a library that favors accuracy over speed, if I needed one, or whether existing libraries properly document how much overhead calling a routine taking nxn matrices for 2x2 matrices takes, if I needed a fast implementation.
Why Is Tech Journalism Such Shit?

Pretty sure that data is uncollectible, due to the amount of work it would take to normalize taxes across many decades and the difficulty in simply sourcing it in the first place.

But at the end of the day, what matters is how secure a new mother and father feel and how much time they get to spend with their child. Obviously, one can sacrifice this in the pursuit of income, but who would want their children to have to choose between future financial security and bonding with a newborn?

Sure, and three days is pretty slim - its easy to be pretty sick for three days with a single occurrence of illness. But the above quote is just a wordy way of saying "you aren't entitled to more sick leave than the 3 days provided for by this law".

Federal law [0] says you cant be fired for taking up to 12 weeks off per year to take care of, among other things, "major illness" (understood to mean that it does not cover things like colds or flu, unless they require hospitalization). But, it also only applies to businesses with over 50 employees, so non-chain restaurants are unlikely to follow this law.

The reason I refuse to read about keto is that pretty much all doctors and public health organizations I’ve seen recommend basically the same things: whole grains, fruits, vegetables, replace saturated fats with unsaturated if possible, low fat dairy, nuts, legumes, fish, some poultry sometimes, strictly controlled alcohol.

Until these guys start recommending something such as keto my basic assumption is that it’s either a weird fringe diet or a diet only applicable to very specific medical issues (eg seizures) that me (not a medical professional) should not try on myself.

If I go to a doctor and they ask how my diet is and I tell them I eat the stuff I listed above, I’m fairly certain they will tell me good job. If I do some extreme fringe thing, I doubt it will be their response with the same likelihood (though a few probably like it).

This is just my personal opinion.

Excellent use of back of the envelope math. I wonder if maybe the loss is non-linear, and a bit more is coming off because the tires are brand new. Perhaps there’s some coating on new tires before they ‘break in’?
Our bees get their nectar from from the many nearby gardens. It is really very interesting how much it influences the taste to have nectar from cherries, apples, pears, spring flowers etc. Most of our neighbours say we have the best tasting honey.
I have no problem with Microsoft selling PowerPoint to the military (although it does not mean I endorse Microsoft, or PowerPoint, or the military; I merely mean that if someone is selling a product and some customer wishes to buy it, then they can do that). It is not the provider's fault what the customer is doing with the products, I should think.

But, their collaboration with NSA for illegal mass spying, is certainly a bad thing to do. They have "been letting the feds read whatever they like out of it without a warrant for the last dozen years", which is no good, and especially if their terms of service does not mention this. (But even if they mentioned in their terms of service, this still doesn't make it good.)

i'm pretty far from a crazy hippie, but i always buy local honey when i can - local honeys always have more interesting flavours, don't cost any more than generic grocery store honey does, and are relatively easy to find. there's not really any downside.
You need to take into account dosage.

They usually have to go through it again, FDA clinical trials (phase i, ii, iii) with different dosage to see what's effective. Increase in dosage can increase chances of side effect or create new ones.

There may be laws to get around or fast track that but pharma company have a dedicated department to figure that out. Just like that one company that causes opioid epidemic.
I used to get this quite a bit when I was in college and had a lot of bad sleep habits. I noticed it happened a lot more when I would take a nap or go to sleep super late. Definitely freaked me out a lot at first, but eventually I learned that fighting was futile and made it worse, while the best thing to do was surrender, relax, and just drift back to sleep a little more.

Nowadays I have better sleep habits and this only happens sometimes after overnight travel, but I still usually remember what's happening and can convince the lizard brain we're not dying and to chill out until we can wake up for real.

Yeah, they use dual tires so that they don't pop catastrophically, not to spare the road from wear.

How does the geofence-based system to determine whether you were in the area of a crime when it was committed know what race you are? I'm suggesting that in the absence of a tool like this, cops will use their eyeballs and knock on doors, and we already know that process is racially biased.

I would also point out that actually getting software into Debian is no fun for newcomers either. The whole mentorship process (where you use some arcane command to upload a package you built yourself to a special website, then ask someone to look at it) is wacky. The project could really improve their onboarding process, or at least make it easier for fly by contributions.

Yes sorry, the project improved a lot since then, all the issues raised in that thread were addressed and several new features were added: we now support serving Cloud Storage backend (such as S3) over SFTP/SCP, multi factor authentication, virtual folders, several filters (for example on file extensions, on source ip address), external authentication, serving Git repos over SSH, per directory virtual permissions (not related to OS permissions) ecc..
