Slack or Discord for building a curated, online community?
Hi hive, I'm the founder of a startup that's building a movement around a new kind of education where families design their child's education through custom classes, tutors, social experiences as a replacement ot traditional school (homeschooling 2.0)

I'm building a community of parents to share resources, ideas, sharing classes/teachers, possibly even for nanny share.

I'm trying to decide whether to use slack or discord and would love feedback from other founders on which has worked better for them and why...and possibly if there's another great alternative I'm not thinking of.

Thanks!
Sure, but my question would be, are you, as the resume writer, more proud of the cert you got via your work or of the work you did at work? I've done cert stuff before as part of my job, but it never rose to the level of being relevant to put on my resume over other things I did.

My rule is always to only put something on my resume if I could talk for 2-3 minutes about it in a way that makes me look good/useful. Most of my certs, the only real thing I could say is "I spent 10-30 hours watching videos and then took a test well." I wouldn't really want to work for a company that valued those skills vs. me explaining how I applied the things I learned from the cert.
Do you have data/source for this? Interested in learning more, didn't think it was this much.
I wouldn't know because I can't see the website.
You are, but you're eating far more grain than you would otherwise be as there are huge energy losses (the animals expend energy being alive after eating the grain) than if you at the grain directly.
And the very next sentence after that one:

"Of the Forbes top 20 private schools, our research found that 14 met fully in person for the entire 2020–21 school year."

So, 6 of the top 20 private schools did not meet fully in person for the entire school year.

Also, that's talking about 14 schools in the entire county, which is a minuscule number of schools and students.

Moreover, what's the evidence for the claim that "COVID did not spread uncontrolled into those homes"? I'm not saying it did or it didn't, I'm just saying there's no basis whatsoever for this claim.

Anyway, the issue isn't just the homes, it's the teachers. Who wants to die for a job? Nobody signed up for that.
Nordic winters are tame compared to those in places like northern north America. I live in a town that regularly dips below -40c.

But a very cold winter is nothing compared to a very hot summer. Look at how many people die in heat waves. Rarely does a cold snap result in more than a handful of deaths, and most of those will be traffic-related. Heat waves can result in hundreds dead very easily. I'll take a Canadian or Norwegian winter over a Texas summer any day.

Parts of Canada are actually about to mandate air conditioning (aka active cooling) in new buildings in recognition of the danger that summer heat can pose in Canada.

I just discovered amex has all these purchase protection features built into their annual fee cards and am finding ways to use them. 90 day return protection here probably would have helped this situation.
Topic reminds me of the book, A Burglar's Guide to the City:

https://www.amazon.com/Burglars-Guide-City-Geoff-Manaugh/dp/...

Which started out as a blog:
https://bldgblog.com/

Unlike the book, this city appears to think the solution to all their problems is to remove the architectures causing issues, instead of trying to make city planning and management choices that enable positive behavior; successful areas don’t have abandoned building, bus stops that function as distribution point for illegal drugs, etc. Police are the last profession that should be making choices like that for a city. Using this sort of thinking, what’s next, make warrentless, no knock searches legal and require every lock uses a masterkey the police have?
Cool, but that’s a different point to make than “I didn’t read the tweet properly and thought my reverse image search was a gigantic gotcha that I’ve proudly posted several times”.
Man, it really is history. Crazy to think had things been a little different how different would things be today. If kid me knew one day I'd run across this in an online forum I don't think I'd have believed it.

As others said- thanks for sharing the insights, made my week.

Every time this stat is brought up I always think it doesn't convey the full context. Even though its in terms of per capita, it's still an absolute amount, I think a better data point to illustrate if the US was overspending compared to outcomes would be what % of disposable income is spent on healthcare vs outcomes.

For example, let's say the US spent 2x on healthcare as some country, but had 4x the disposable income, would this still be overspending or would it be more efficient given the amount relative to income? The closest I can find is health spending as % of GDP but that doesn't capture what a person's income, since it includes government spending too, so it obfuscates whether or not the inefficiency (if any) lies in private or public healthcare in the US.
Ask HN: Autocurrying Syntax Sugar?
Full disclosure: I'm not a computer scientist, I'm just a programmer who uses these tools. Also I mainly use javascript and go, I need to spread out more but these two tools fulfill 99% of all my needs.

I had a 2am idea and when I looked it up I couldn't find any mention of someone else thinking of it. Here it is:

Function currying is a method for saving arguments on the callstack so they don't have to be copied in memory between calls. Here's a javascript example of currying:

```js
const add = (leftOp) => (rightOp) => leftOp + rightOp;
const addThree = add(3);
console.log(addThree(4)); // 7
console.log(addThree(-2)); // 1
```

I think all PL that support the "putting-functions-in-variables" paradime can do this. BUT. If you try to call a normal function that requires all of its arguments up front without all the arguments it will throw an error. So what if it didn't? What if instead of throwing an error, the function call returns a curried function with the first arguments filled and the unfilled arguments left to be inputted.

```js
// with autocurrying
const add = (leftOp, rightOp) => leftOp + rightOp;
const addFive = add(5); // addFive is defined like addFive = (rightOp) => 5 + rightOp
console.log(addFive(3)); // 8
```

This could work in Javascript(/Typescript), Python, Go and similar languages. By encouraging currying you could potentaily get memory saving, readibility, and performance. But I won't ever try to sell you a stack of pros without a foundation of cons: any syntax sugar has the potential to cause logic bugs, reference bugs, and missuse.

What do you guys think?
> In the large, I don’t think the prob­lems open-source authors have with AI training are that different from the prob­lems everyone will have. We’re just encoun­tering them sooner.

Call me a pessimist but it seems really unlikely that AI will cause problems so much as continually increasing automation. It makes such terrible choices around qualitative decisions and increasing existing AI to a general solution pretty much always fails.
My 1955 M3 with a f/2 Summicron, that I talked my dad into buying back then, still works fine. A new aspheric 50mm f/2 Summicron, lens alone, is now $12,560, about 25x what we paid for the camera and lens together.

The new lens is "better", but the old one gives a classic softness.

And, good b/w film is still available[0], though Kodachrome is, sadly, gone.

> It think Rust is easier on beginners, in many ways, than C. And C is easier on beginners, in many ways, than assembly or machine code. But if you want to really understand computer programming, starting at machine code or at least assembly isn't a crazy way to start.

I mean sure. But equally, starting with Python isn't a crazy way to start. And Python is much easier language to learn than any of those (esp. if you want to actually create something practical with it).
Yes, Justice Thomas mentions some of the most major 14th amendment rulings and says they were ruled wrongly. One conspicuously missing ruling was Loving v Virginia. The one that prevented states from banning interracial marriage. Does this sound like someone standing on principle? Or perhaps more like someone who doesn’t care about others’ rights but don’t touch his own?

Several states have already had debates in their state houses about outlawing some forms of birth control (Louisiana and Missouri off the top of my head). This was prior to the decision, now they will be more emboldened.

The Texas governor when asked if he could go further and outlaw birth control simply responded “I don’t know.” You wildly underestimate how extreme these people are and how little they care about what the majority want.

To answer your final paragraph, there is a very long history of _certain_ particular states in a _certain_ region in America with a _certain_ evangelical Christian makeup who has been trampling rights for centuries. These people argued states should decide slavery and Jim Crow laws as well. Being blunt, history has proven over and over you’re on the wrong side of this.

And, for what it’s worth, until gerrymandering is fixed there is a tremendous problem with letting the minority political party in the state govern.

For instance, in Wisconsin over the last 3 elections, Democrats have been +4%, +8%, -3%. One would expect their state house to slightly favor Democrats. Republicans have held a +29%, +27%, and +23% edge.

Almost every red state is like this. This is how you have relatively purple states like North Carolina, Texas, and Florida take absurdly hard right positions that in no way represents their populations.

The Texas GOP just days ago released their platform calling for a state-level electoral college for all state-wide positions so they can maintain control of governor, secretary of state, attorney general, etc. without coming remotely close to winning the popular vote.

Hope that helps explain how it is very much the DEFINITION of undemocratic and what’s wrong with it.
Personal story time. Back in 2005 I came to the US for the first time through the Work and Travel program. I was working as a lifeguard and had a lot of free time while nobody was in the pool. I decided to take a Zend Certified Engineer certification - back then it was PHP 4 - thinking it might help me get a CS internship in the US next summer. I passed it and 3 months later Zend offered me to take a PHP 5 certification for free. I was already back in my home country and of course I agreed. After passing the exam it turned out I was #8 overall and #1 in my country to pass it. I put it on my resume.

6 months later I found a job and moved to Boston. After working at that company for a few months me and my boss went out for drinks and I asked him why he decided to hire me. He said that my certification was basically a deal-maker. He thought it was a sign that I was at the top of my profession. I thought it was funny, but, hey, it worked.

Super fast forward - a few years later I Fat FIREd at the age of 33 and I'm absolutely sure that the initial certification set a certain chain of reaction that led to it. So even though I think in most cases the certifications are absolutely useless, I'm absolutely sure that when you have to stand out from the crowd, especially at the junior level - they are super useful.
In my home state of Wisconsin, redistricting used to be completed by a panel of elected judges. This process Created competitive districts that both parties grumbled about but lived with. This process was take away from the judges and put in the hands of the elected representatives, but those representatives have a direct personal interest in trying to draw those lines such that the districts are non-competitive in their favor. I’m not sure why you view this outcome as more democratic.
> Variable-gauge trains are things we can build, and as a matter of fact there are a bunch of them crossing the French-Spanish border every day.

The high speed lines are all standard gauge in both countries.

At the crossing between Puigcerdà and La Tour de Carol the Catalan regional train goes one stop into France on an Iberian gauge line which ends there (English Wikipedia needs to be updated to reflect this). At the crossing between Cerbère and Portbou it's the opposite, with a French train going one stop into Catalonia on a standard gauge line which ends there.
Maybe, but that's assuming criminals are no more likely to opt instead for going clean if circumstances change in such a way that committing crimes becomes less rewarding than it is for homeless people to "opt" for purchasing/renting a home if circumstances change that make sleeping rough less attractive.
I mostly see it as a bad faith argument for why the only possible productive use of x fraction of land is for growing feed and herding cattle and didn't know the 'animal feed corn' and corn as a grain for people are the same crop.

If it's basically the same level of involvement as as bleached flour, then the only real relevant issues are how to source a balanced protein so you don't have to eat half a kilo of carbs when you don't need the energy and how distructive other micronutrient sources are.
The headline is "Our European visitors are important to us." Clearly they are not. I most often see this on US local news sites.
It is a tricky thing. At some point someone needs to be paid for writing the article. I can think of 3 ways to accomplish that at the moment:

1. Government subsidizes media. No cookies or profiling required. However, unclear if one government should support articles that are mostly read abroad and, of course, there are many issues with this related to equitable distribution of funds and impartiality.

2. They can run ads. However, ads tend have better ROI when well targeted which requires profiling. For instance, if I am reading an article about suits. If they know my age they can make sure to show me people around my age wearing that suit. Which makes me more likely to envision myself wearing it and thus buy it. Cookies (or similar) required.

3. A paywall where the reader pays for it directly. However, we seem to be very resistant to that idea given we were trained to use a "free" (sell your data model) internet. Nonetheless, by seeing your browsing history from your account server-side (no analytics cookies needed) they can place you in cohorts server side. So not that much more private. If anything, less private since they have your real data through your payment method.

Ensuring privacy while still getting access to free things and not bankrupting companies (especially small ones) is a hard problem.
Excellent. Moved me.
A great teacher once said to me that freedom without heart is a very dangerous thing. I thought that was wise.
I grew up in a land where 95% of the farms grew the same two crops and it was unsettling if you think about it. When mosaic virus started to become a problem here there were a number of stories published about how few grains represent most of our calories and two epidemics happening in the same year or couple of years could put us into a very, very bad situation.

I decided probably 20 years ago that the simplest thing I could do was to eat multigrain bread, based on the observation that it's not just acres of alternative grain that matter in a situation like this, it's experience with grains that matter. A farmer who has grown 5 acres of millet for a decade can easily ramp that to 50, 100, and his neighbors can impose upon him for advice to do the same (probably the next year or the year after since farmers gonna farm).

But if you don't know anyone who grows millet or sorghum or chia or whatever, it's going to take you years to sort that out, and if you're older you might just decide to try to avoid having to change at all.

My kid goes to a private school. Not only was it closed less time than the public schools, but when my second grade daughter fell behind in reading (because distance learning doesn’t work) she got private 1:1 tutoring every morning to catch up after returning to in person school.
I definitely wish more recent tech had gone the standardized way similar to how IBM standardized computer building. We’re into four decades of being able to build PCs from customized/off the shelf parts because IBM didn’t go the “make it impossible”/proprietary route.
It's a bit glib to say that even the most leetcode interviews "require memorization". It's certainly possible to do most of them from "memorized" first principles of how various bits of CS components work instead of brute-force memorizing, and in general even when I do code problems on interviews, I mostly try to use them to either demonstrate that or determine that the candidate actually understands WHY you would do things that way.

Certs on the other hand are often just pure memorization. There's not really any way to "infer" which AWS service name matches to which service function. You either know the name of the API call or you don't. It doesn't provide much signal that you actually know how to apply that information to anything practical.

Even at their worst, most crappy whiteboard code interviews are still literally testing if you can literally write functional code, which is closer to what you do on the job than memorizing the Cisco books.

Definitely going to give that a read. Now that you both mention it, many BigCo's did have fragmented segments back then, were I suppose now everything is helmed by the head (Alphabet/Google).

Maybe it was some kind of turning point. Also about that time did CEO age drop through the floor? They went from all being ancient to mostly 40 and under somewhere along the line.

Thanks for the book suggestion!
Yes, but a reasonable bitcoin wallet wont let you spend the same coin twice, even if offline. As far as I know, none of the common wallet software that support offline transactions will let you do this by accident.

Credit cards suffer from a similar problem, the transactions will not necessarily go through when you get online.
Or do both!
It is a really depressing reality that we have carved out. It isn't even clear to me at all what we've gained through this destruction. It also isn't clear if the Green Revolution was a net long-term benefit.

You might be interested in the book Against the Grain: A Deep History of the Earliest States by James C. Scott. I have it sitting on my desk and have watched some talks by the author, but I haven't gotten to the book yet.

That would be an argument against any attempt to clean up crime that wasn't done at a greater-city-wide scale. And maybe that really is true - the only genuinely effective measures you can take to reduce crime have to be applied to a sufficiently wide area. I'm not sure if we have enough data points to draw that conclusion though.
The problem with this kind of post is not, as you might surmise, that people disagree with the notion that reducing meat consumption is helpful from an emissions perspective.

It is that the binary presentation implies an either-or when in fact both are helpful.

Plus it just shits on people and nobody likes that.
I was going to add the EPA 608 as well. Not only does it allow you to buy/use refrigerant, but it usually counts for warranties for HVAC equipment. Mini-splits and things like that usually want a 'certified technician' to do the install (or at least the refrigerant work), and your EPA number qualifies you. My state doesn't even have the concept of an HVAC licensed contractor, only the EPA cert applies.

Note: the EPA 608 has multiple levels. For mini splits under about 2 tons, you might be able to get by with just your EPA 608 core and Type 1 (small appliances, <5lb of refrigerant) Type 1 + core can be done online, open-book, and costs $25. Nobody should install a mini split without it!
String used to be StrBuf first. The rename to String was intentional because String was the more commonly known name in other languages.

I'm a sales engineer and I think this tool could be useful.

I would also look at driving leads based on customer pain points.
If I could train your system to use my docs that would also be useful. I would also want to exclude my competitors from my training data.

Maybe also focus your tool around government RFPs. There are a lot of consultants out there who make a lot of money writing proposals for various companies and it is quite
time consuming.

Other questions:

Does it make sense to have a salesforce integration?
Does it make sense to have a Jira integration?
Does it make sense to have a confluence integration?
Does it make sense to have Google Doc or Office 365 integration?

Maybe make these plugins and attend a Salesforce and Jira conference or two.

Good luck!
Agriculture consumes a lot of water in this drought stricken state. The worst part is that many of these farms pump water from the ground thereby collapsing underground aquifers. This is an irreversible change and has caused the Central Valley to sink by several feet over the last few decades. There is zero political will to solve this. Instead we waste time and energy on pointless green initiatives, desalination and harassing homeowners to stop watering lawns. Keep in mind the labor used to grow these plants is imported as well.

California is a very wealthy state and giving up some of these agricultural businesses to other states and maybe even to our poorer southern neighbors will be an overall good thing with minimal loss in tax revenues. These lands should be used to grow trees instead.
Aurora still can't do zero downtime upgrades though, which surprised me. You get closer with vanilla RDS PostgreSQL. And if you use RDS proxy or pgbouncer it's better.

At a previous company I had to tend to a large here of MySQL clusters and we did all sorts of zero-downtime stuff there. I've found MySQL replication far easier to work with.
If you need this, you can split your application in two parts: one which creates the objects, then these objects are serialised to a 'configuration file formats' which can be audited and then used by the 'real' application.

IMHO this kind of audit is useless because even if one option has the expected value what guarantees do you have that this option is used as expected? Well you have to audit the code!
