I think there is a big difference tho. In the United States, a 15% tip is considered the bare minimum from a cultural standpoint. I was raised to always give 20% — 15% is what you give for subpar or bad service. I think I’ve only given less than that once in my life (intentionally anyway).

This is to say nothing of the variation in check size. You have a whole range in full-service dining from small checks all the way to fine dining, where alcohol can add hundreds of dollars to a meal, that can make for really good tips. For the right personally type, this can be really lucrative. (Bar fending is even more lucrative. My older sister was making six figures as a bar tender at a chain restaurant in suburban Atlanta 15 years ago and I don’t even think she worked 30 hours a week.)

Food delivery has always been different. Historically, most drivers/bikers for a restaurant got an hourly wage and tips, but tips aren’t usually based on the price of the order. Sure, there are exceptions (really large orders), but if I order a $45 steak from delivery or a $15 pizza, the tip is often going to be $5 or so either way. That’s just how it works. And even then, tips are often withheld more for issues such as timing, whether food arrives hot or cold, etc.

With food delivery apps, tips aren’t guaranteed the same way they often are for non-apps, in part because the apps charge their own service fees that are often confusingly displayed to the customer (who might not understand the difference) and because the relationship between restaurant and driver/delivery service are often separate. When I call my local pizza place and order delivery, they send their own person. If the order is wrong or late or has an issue, I can call the restaurant and figure out what is going on, demand a refund or get something re-delivered. With apps, I have to deal with the delivery service, which is often a PITA — and in most cases (Seamless/Grubhub being the exception), the delivery driver doesn’t have any connection to the restaurant anyway. (I’ll say that the 7 years I lived in NYC gave me great respect for Seamless (Grubhub) because they always took care of me, but as that service has had to compete with Uber etc., it hasn’t been as good. That could also be a Seattle thing.)

For me, when I use Uber Eats or Door Dash and I’m charged a $5 order fee, taxes, whatever inflated rates the restaurant is charging over menu price, and the delivery driver is often de-incentivized to even come to my door (or in the case of Uber Eats, will not), I have to be honest and say that my inclination to tip more than a few dollars is often lowered. More to the point, if I give a large tip and the driver can’t even be bothered to come to my door (and I get it, go down the elevator and wait outside - but part of the reason I order out is to avoid putting on shoes), I’m now pissed off I’ve given someone $10 to deliver lukewarm food that came with lots of fees. And no matter how unfair it is, that is going to impact how much I’m willing to tip with those apps the next time.
You can't do anything without trust, so drop the faux-contrarian cynicism.

Seriously: everyday, you rely on thousands of facts that get to you via intermediaries. News, obviously, but also the map data for your navigation, the lunch menu at work, the flier with your daughter's soccer schedule on the fridge, etc.

Of that information, you can validate almost exactly zero from first principle. I have not, for example, ever verified that Japan exists or Donald Trump is president.

So what you do is: you develop relationships of trust, with people (you are more likely to give your spouse the car keys than any stranger), or with institutions (google, New York Times, the Iraqi Information Ministry).

These people/institutions have the interest of keeping you as a reader (or lover). That means even if they could profit from selling you out on any single issue, they would risk being found out and losing far more. It's iterated prisoners dilemma, essentially.

Peoples' assessment of quality media like the Times or Economist has also become completely unhinged from reality. Re-read their coverage of both Mueller as well as the current Ukraine affair from the beginning, and it's astonishingly accurate. The Times had an almost complete if maybe rough outline of the Ukraine scandal on day two after the first rumours, for example.

> you basically just "borrowed" money from your vehicle.

so wouldn't it then make more sense to just sell the vehicle for $10003, then place that money in an interest earning asset like a bond, rather than "borrow" from the value of the vehicle?
Support for reader view would be better than any of those options.
There is reason to consider this a possibility, since many molecules may be potentially harmful when inhaled as vapor, with unknown health effects (ie vitamin E acetate), but under combustion would deteriorate mostly or entirely into the carbon forms that have well understood effect on health -- as a previous commenter mentioned, 10yr lifespan reduction from long term continuous cigarette use.

There is just not longitudinal data available for vaporizing plants or synthetic nicotine/thc concentrates. It could be an even higher lifespan reduction than smoking!
Tell HN: As of today I'm swearing off Reddit
Today I was told by reddit that if I wanted to view a subreddit, I would have to download the app. Instead I'm blocking the site and swearing off of it. I want to invite people to join me.

I've slowly come to realize that of all the social media time wasters I use, reddit is by far the most insidious and damaging to the normal functioning of my thinking. I've had several times in normal conversation where I'd mention that some trend or fad was annoying me only to have everyone else I was with agree that they didn't find the thing to be that widespread. Every time i would think back as to why I was so hyperaware of that specific thing, it would come back to the fact that it was a mode of thinking that was super concentrated in the reddit echo chamber but probably not that prevelent outside of it.

It is such an intense echo chamber, and it starts to feel normalized because I relied on it heavily as a crutch when I was bored and I was consuming the same content over and over again.

I'm not going to say I never got any positive interactions out of reddit, but when I think back, those positive interactions are extremely few and far between and are drastically overwhelmed by repeatedly reading low quality content that made me question my sanity and the sanity of the society around me.

I don't use Twitter but I have a feeling everything I'm saying applies there as well.

It's not a healthy place and today I'm swearing off it. If If I could inspire anyone who feels similarly to make the shift with me, I would be happy to hear it.
Yup, exactly. Kimball's stuff is the best. You can achieve on a modest machine what modern techniques would require an incredibly expensive horizontally scaled MPP database. It does require a lot more planning and forethought to be certain.

Pure CBD Tincture
Try not to need to smoke therapeutic weed? A CBD oil tincture can be a reasonable other option, especially for kids. In this way, regardless of whether you're experiencing nervousness, diabetes, sorrow, joint pain, skin break out, or any of different issue for which CBD may be gainful, you can converse with your primary care physician about utilizing a tincture to get results. Ace tip: When looking for CBD drops, stay with items produced using the hemp plant's stems, leaves, and stalks, as opposed to the seeds, which contain little measures of CBD. Note: You don't need to purchase a liquor based CBD tincture on the off chance that you would prefer not to. You can likewise locate that huge numbers of the best cbd oils for torment are made utilizing transporter oils, for example, coconut, olive, and almond oils. A considerable lot of the Specialists have gotten especially captivated by the medical advantages of cannabidiol, so look into has been expanding around there, which is awesome news.
Like you said, not easy: Recreating the functionality of views using triggers is error prone and a heavy maintenance burden, and the triggers have to be implemented differently based on what each query is like... In a lot of cases it's better to just optimize the query and indexing.

In PG you can make a lot of queries run straight from one index if you tailor an index to a query, since you can index your own plpgsql functions.

> Learning to spell isn't memorizing lists of words, it's learning the rules of English and how words are actually put together

Learning those rules involve learning the orthographies of French, Latin, and Greek, etc. as well as their associated transliteration schemes(usually multiple per language), and memorizing which one was used for which specific word(Hamburg[0] vs. burgher[1] vs. bourgeoisie[2] vs. Berger[3]), as well as words where the etymology was erroneous (ex. scissor[4]). I don't think most people actually learn this.

Unikernels Can Fulfill the DevOps Promise
Well, fair enough. Let me explain a bit how it would be done. Finding the "first packets" is not as easy as you may think.

The two fields in the network protocol that matter are the destination address (DST) and the endpoint ID (EID). These identify the flow uniquely. I'll write this header as DST:EID.

So you find some packet that has, let's say 1000:100 as the header. Now, that flow was established at some point in the past with two packets, that are sent between components called the flow allocators. Flow allocator packets are all sent to a fixed EID, 1. So there will have been an exchange in the network of a packet with 1000:1, and a packet send back from 1000 to the source, SRC:1 (you don't know the source yet).

The contents of the first packet will be (relevant fields only)
1000:1:SRC:X
with SRC the source address, and X an endpoint ID chosen by the source. When the destination receives this, it generates its EID=100 and sends the following information to the source's flow allocator:
SRC:1:X:100

The source knows from X that the message is from 1000. This is enough information for both endpoints to know the <ADDR, EID> pair of their peers. An interceptor doesn't know SRC or X. You could look for all packets and find that "100" field, but how do you know it was sent by 1000?

It will take quite some traffic flow analysis to match these two packets. Probably it will be easier to try to match the actual data flows.

Now take into account that networks have multiple layers, and all flows are established this way.

It's definitely not impossible. But it's harder than just reading the first X bytes off a packet.
You don't need a windows build server to build a windows app, its just an executable that targets a given cpu architecture or run-time.

Have you tried building a native or .Net Framework app on a Linux machine? How did that work out?

Its not about affording a Mac Mini its about being forced to do IT on some build servers when the rest are visualised in the cloud. Having your cloud servers ping back into your physical office to do the Mac build is stupid.

Because no one ever pushed code to Github that “pinged” to another server located somewhere else or pulled dependencies from yet another server like Nuget or npm...

I’m all for “the cloud”, but a VM in the cloud is no harder or easier to manage than one in a local server room. Especially since with most build systems, the orchestration is happening on one server with build agents hosted on different servers.

You want to build the product on a dev box? That's not good CI. You want these environments to be clean and preferably spun up fresh each build.

I never said that. But with most build systems it doesn’t matter where the agents are or where the orchestration server is. The agents register with the orchestration server and you can “visualize” where the agents are.
Is this benchmark a good one?

Any benchmark which reflects a task that humans do is a good one, unless it has specific weaknesses that a computer exploits.

I'd use models that are written for this is my work, so I find it useful.

I feel like this is true of any new benchmark.... give some smart folks a few months and they can now beat the task.

In NLP work this use not to be the case. 5 years ago we were stuck at a local maximum.

And this undervalues this task - this bridges the gap between unstructured and structured data. In many ways it is the holy grail for many tasks.
No, because you need the cash now. Doesn't matter that you will have thousands more in a few years when you don't have money to buy food now.
Oh, restaurants totally change prices based on eating in or delivery. Often, places will have different prices in different apps too — depending on what the costs are for them. I’ve literally played arbitrage between Seamless, DoorDash, Postmates, and a restaurant’s own website before to find the lowest price because the price was different everywhere. There are also places that won’t list in an app but will have delivery on their own website that is then sourced to DoorDash.
We have improved it a lot, but the wheel has been round for a very long time. We laugh at people who reinvent the wheel as opposed to doing incremental improvements on it.

We do have ships, rockets, and a few other things that don't need wheels (tough they tend to have wheels of some form inside), but the wheel itself is still just incremental improvements on that first one way back...

1. Owner didn't pay me. Lots of manipulative BS. Wanted more money.

2. Startup seemed okay with me being remote at the start but weren't actually okay with it.

3. Contract ended amicably with contracting company.

4. Job seemed okay but they sold the client on an impossible deadline. Left when shit hit the fan.

5. On a very longterm contract but grew bored with the tech and suspected the contract would get cut short so I jumped to something that seemed more long term with potential to learn something new.

6. CEO made promises and didn't deliver so I'm fielding offers and will probably leave once I get something that pays more.

Lessons:
1. You make more money every time you jump ship.
2. Don't listen to what people say. Listen to what they do.
3. No boss/company is interested in providing you with opportunities to learn. They all want to exploit an existing skill set and all real learning has to happen on your own time.
4. Employers don't really want remote. They give it begrudgingly because enough of the talented people are demanding it.
5. It's probably better to just let contracts end, then double-dip during the transition.
6. These people aren't your family.
One of the key assumptions that's being made, throughout this thread, is that astronomy is mostly imaging. Taking or stacking images. A ton of astronomy is spectroscopy, which is nothing like a stack of static images with one that has a streak in it.

> they're to boost your server's pay up somewhat closer to a living wage.

and by doing this, you're just perpetuating the problem. If the base pay is too low, the worker _needs_ to quit, but if you force yourself to tip just enough to string them along, you're only kicking the can down the road.

Edit: to clarify, the tip isn't included in the sticker price of the meal/service. Therefore, a business is indirectly mis-advertising the true price of their product/service, and thus, gain unfair advantage in the market. The business then surreptitiously charging you more by adding the tip, and therefore, the true price is hidden until after you're already completed the meal, and too late to refuse the tip.

Everything is in your environment generally lower, shorter or inappropriate for you... This trigger improper posture and inevitable backpain.... Chronic backpain in my case.

After passing through everything, including painkiller, osteopathy, chiropractic, surgery (back bone injection) without any better results I tried (pure amator) weight lifting and this was a miracle for me.

My situation get much better, in just a matter of few months.

My 2 cents on that is weight lifting force you to fix your posture and imbalance when you practice it. Muscles have Memory, and this, even if it is counterintuitive, help a lot.
This is just a demonstration of how naively optimizing the expected value is not actually "optimal" in general.

There are two fundamental strategies for the robot. One is to stay on L forever, and have a 50.1% chance of receiving... let's call it `x` amount of reward, and a 49.9% chance of receiving nothing. The other is to move back and forth (L, center, R, center), which has a 100% chance of receiving `x/4` reward. (In theory the robot could also stay on R forever, but that's strictly inferior to staying on L, even if only slightly.)

The robot can also use a mix of these two strategies, e.g. by moving back and forth but waiting an extra turn every time it's on L. This increases the worst-case reward at the cost of reducing the best-case reward.

Let's rephrase in gambling terms. Suppose you have a one-time offer to bet any amount of money and then flip a fair coin (well, a 50.1/49.9% coin). If it's heads, the money you bet is quadrupled; if it's tails, you lose the money. Then the first option above represents betting all your money; the second option represents betting nothing; mixing the strategies is equivalent to betting only some of your money.

What would you do? The expected value of the money you come away with is 2x the money you bet, so if you're optimizing for expected value, you'll bet all the money you own. But most people wouldn't, because the risk of coming away with nothing is not worth the possible benefit. Personally, I might bet some of my money, but there's a good chance I'd bet nothing, because I care much more about the worst-case scenario than the average scenario – at least when the chance of a worst-case scenario is so high (almost 50%!).

You could argue that monetary gain is not the same thing as a reward function, and risk aversion should be modeled as part of the reward calculation, so that you can, in fact, optimize the expected value of the reward function. But in that case, the robot just has a bad (or non-human-like) reward function, so it's no surprise that it makes strange decisions.

There are 2 different "use your own SSL" solutions at the moment (for enterprise):

A. Uploading your own certificate - this just uploads it and CF still does HTTPS interception.

B. Spectrum - Cloudflare will proxy the actual port 443 TCP connections (which might be the plan for SSH connections to GitLab that are not altssh.gitlab.com). The issue is that this only does layer 4 IP reputation DDOS protection; no WAF, etc is done so this most likely isn't what they will do for the main gitlab.com site.

It could apply to chemistry, or physics, or any other lab-centric field.
