What about the name and domain for an app
How do you app builders do with the name of the app and the site's domain?
I'm building an app that is like airBnb but with another thing. Before airBnb became big, people probably didn't search for home to rent. It was probably more a marketing thing or "mouth to mouth" thing. They didn't choose "rentresidence.com" or another SEO name. Spotify didn't choose "streammusicplayer"...

So what should I do? Find a name that will tell what the app will do or take a cool name that no one will ever guess what it does?

They post a profit or about 33% according to others in this thread. This means they still have ~2 billion pounds in actual operating costs.
Not that I support the current model, but that work still needs to be done, and it seems naive to expect it to be done for free / substantially less.

I wonder how far the 'fee per published article' gets to covering bare costs for e.g. the journal Nature.
Services you run on AWS are isolated from Amazon. It is part of their legal agreement. This is important so that businesses can store sensitive data on AWS without worrying about Amazon using this data for their own use cases.
Yes, that's right. NP-hard doesn't mean intractable in general, though it has acquired that reputation among computer types. Large mixed-integer programming programs (millions of variables) are routinely solved in reasonable times (seconds to less than an hour).

Sure, full or brute-force enumeration algorithms makes you hit the worst case complexity every time.

However, most commercial mixed integer solvers don't use brute-force enumeration. Instead they pre-analyze the problem, and then employ a boatload of mathematical techniques--including heuristics--which exploit problem structure and prune off non-solutions and helps the solver reach a solution fairly quickly on average. (luck is involved, of course)
Yeah, and clearly bright as hell if he could string together something as complicated as TempleOS. Imagine what he could have done if he had been able to direct it towards something more globally useful. RIP dude, hope there's a reward for determination in the afterlife.
Except the next generations can't time-travel snatch the current population:

Technically it can put aside money while it operates: this either makes it somewhat scarce now to the benefit of current capital holders, or this encourages injection of fresh money by the central banks.

Then if in a few generations away something goes wrong and the stash of money is released it devalues money by buying up labor manhours (thus making manhours scarcer for all the holders of capital in the future).

That's another thing as well, there's the line that teachers have to provide their own supplies. But the degree to which is left up to the teacher.

And then there's the months off.

I'm pretty orthogonal to it now considering my wife is an elementary school teacher. And there is a degree of truth to the complaints, but they are often exaggerated as well. She still complains about how much I work.

I'm glad people are finally catching on to this fashionable narrative-generation tactic. When a reporter writes "X people are doing Y", all that means is that at least two X people each did Y at least one time. That's it. It doesn't mean Y is common or ascendant among X or the typical X does Y or even that any X is at the present moment continuing to do Y. This kind of headline sure sounds like a broader claim though!

Reporters and editors are people with a knack for language. They understand that for this phrase, the gap between denotation and connotation is a chasm. That we see this particular phrasing constantly anyway suggests a certain malfeasance.

I'm really tired of having to read my news adversarially.
Work starts at 8am sharp. Dealerships around here open at 10am, close at 4pm.

Like I said — Doctor's hours.
I would disagree that it's the "wrong" analogy to make... maybe just different.

To me, insider trading is analogous to court siding, in that, in both cases, someone is seeking to use "private information" (information that isn't yet publicly available) in order to make money. So I would order the system:

1. Action occurs "privately" (firm decides on merger but hasn't announced it publicly; court sider reports data that the ump hasn't recorded yet/doesn't record; player notices how dealer plays the cards)

2. Party with the private information makes bets based on this information in an effort to beat the system

3. The public finds out about the previously private information and responds accordingly.

So, courtsiders don't have knowledge about what the player WILL do, but they can tell people what the HAS done faster than they would get normally.

Though I can understand how card counting may be a better analogy for courtsiding simply because of the fact that they're both legal gray areas, as opposed to insider trading, which is explicitly illegal.

Cars last longer than 12 years. If your baseline is a 20k car then keeping the X for longer than that or buying used is reasonable.

Really though the upside is more you have the performance of a high end car for lower lifetime operating costs not that it’s cheap.
The median personal and household incomes in 2016 were $31k and $59k, so at $38k you're starting your career well ahead of the median for US citizens of all ages. I happen to think teachers should be paid much more because of the importance of what they do, i.e. I think they're paid less than their potential worth, but I don't think it makes sense to paint teachers as low-earners in an absolute sense. Unless the point is that the median american is a low-earner in an absolute sense, which is fair enough.

The trouble is that it's really not possible to be a portable assembler. Sure, most processors have instructions to do arithmetic operations, but at some point you're doing things that not all processors support. So either you're going to have to drop the "portable" or "assembler" part at some point.
No doubt certain other, cough[0], influences inhibit that checker too.

It's partly that a strong USD means that people are buying dollars or moving money to the US. More money to the US means less money to others.

It's partly borrowing. Lots of developing nations' loans are denominated in dollars. Meaning that they have to pay back the money in dollars since lenders worry that developing nations/peoples would just devalue their money to pay back their loans if the loans were in pesos, liras, etc. As the USD gets stronger, the loans become more expensive.

Ok role playing time. Your a teacher. You majored in some subject like music or English. You probably spent 4-5 years in school. Maybe you have some debt. Your working as a teacher right now making 45k. What do you do? Getting an education in something useful could take 4 years + debt. You could goto trade school , 2 years?

Governments are a function of their laws. I'm not sure what you mean by, 'are allowed and expected to keep secrets from each other'.

I don't actually allow or expect my government to keep secrets. I don't think 'they' are even authorized to. If 'they' could, 'they' would not be a representative government, of, for, and by the people.
I saw MoltenVK under KhronosGroup control here, which led to my confusion once more: https://github.com/KhronosGroup/MoltenVK

And yea, the messaging is confusing because of this line on their site:

> As a first deliverable from the Vulkan Portability Initiative, Khronos members Valve, LunarG, and The Brenwill Workshop have released a collection of free and open source set of tools, SDKs, and runtime libraries to enable Vulkan development on macOS and deployment on macOS and iOS platforms

Source: https://www.khronos.org/vulkan/portability-initiative

That led me to think they’re sponsoring it.

It looks like MoltenVK was created by The Brenwill Workshop.

I'm not sure what you mean by open sourcing. There are published procedures in open access journals for creating neural organelles from tissue samples.

It is interesting to think about how organelles might develop around a mesh of stimulating wires in a computer interface.

Using cells from non-primate animals (e.g. rats) might alleviate some ethical hurdles. Still, I am somewhat uncomfortable with the thought of the idea of creating boxes of neurons trained via a interfacing mesh to accomplish certain types of computations, etc. The hard problem looms.

Currently neural organelles are being used to study disorders like autism in humans where taking brain samples is unethical, but taking a blood sample and coaxing them into neurons, is not.

Its hard to add up the entire cost of the car. There's the cost of time spent; time without a car; lost opportunity due to car issues. And in the end, you're driving an old, worn car which isn't as 'valuable' as driving a new, unworn one.

Depending on how all this is weighted and added up, it can be the right thing to replace a car sooner than later.

Most modern solvers like CPLEX and Gurobi have built-in heuristics [1] that are automatically selected and applied without user intervention. They typically exploit the structure of the problem or encode the experiences of the developers over large problem testsets.

The default heuristics for commercial solvers are actually pretty darned good these days and there's typically no need to hand-pick them.

In the MIP world, they are the secret sauce to fast solution times.

Hyperparameter tuning has been studied for MIPs (many papers written on this), but ultimately they are black box solutions. My experience inclines me to not even consider hyperparameters except as a last resort or unless you know something specific that a hyperparameter can exploit; there are other more high leverage things than can be done.

Random perturbations to the problem have been found to be much more fruitful for forcing a diversity of branch traversal paths and have lead to significant speedups. (M. Fischetti popularized this idea in 2010s [2])

A critical advantage of these new FPGA boards is not only are they at the same price point like Arduino clones and many other common maker components, but they are also small enough to be useful as permanent component in a project.

With earlier FPGA Learning boards, the designers tried to cram a ton of stuff into them, usually a gazillion pins, leds, input devices and connectors. You can't easily put that on a Raspberry Pi or Arduino.

> Toys "R" Us went bankrupt because they thought they were a toy-selling company, instead of a child entertainment company. These companies fail to innovate.

Not exactly [1]

"Toys "R" Us' debt problems date back to well before Amazon (AMZN) was a major threat. Its debt was downgraded to junk bond status in January of 2005, at a time when Amazon's sales were just 4% of their current level.
[...]
A year later the company was taken private by KKR, Bain Capital and real estate firm Vornado. The $6.6 billion purchase left it with $5.3 billion in debt secured by its assets and it never really recovered.

But much of the chain's resources were devoted to paying off that massive debt load rather than staying competitive.

When Toys "R" Us filed for bankruptcy in September 2017, it disclosed it had about $5 billion in debt and was spending about $400 million a year just to service that debt."

I really enjoyed Never Split the Difference. It has helped me with negotiation in life.

Ask HN: What methods and tools can I use to decrease my app churn?
About three weeks ago I launched my app as a solo dev and without any marketing or buzz I've been able to convert paid subscribers and sell products. I know its an app with a viable market, and has potential. However I have a high churn rate (install/uninstall ratio) of about 70-80% that I know I could improve. Just to put into perspective I am getting an average of 150 installs/day and about 115 uninstalls. So I gain about 20-30 users/day and of those I am getting 3-5 free 3 day trial signups.

Currently my app has a couple of issues with a few crashes a day which I am working to resolve but I don't think that is the culprit. My design is decent, it performs decently and its not too convoluted. I use google analytics to track events but they are more of a way to report how much activity my app gets rather than reports on how people feel about my app.

I have about 500 active users and about 1,300 accounts. I used mail chimp to retrieve feedback about two weeks ago when I had about 200 active users and 400 accounts and I received only a couple of responses from people saying they really liked it, with just a few minor suggestions but nothing really enlightening. Just today I used to the new search keyword feature in the play console that allows you to see by which terms your users found the app. I have two keywords which I am targeting and have a very nice 50% conversion rate but mostly all of my installs come from keywords that are not listed and get placed in the "other" category. So I am a bit lost since I feel like the app could be optimized right now as its still very new before I try scaling out and just churn through more potential customers.

I am looking for advice in general since I work alone but more specifically are there any tools/methods that could aid me? I came across https://www.appsee.com/ which looks great to be able to see how users interact with my app but I was unable to get a response? (maybe they don't like the little guys)
i'd bet that proto-beer and proto-bread appeared around the same time, and techniques were developed over generations to calibrate different recipes until they resembled what we might recognize as "beer" and "bread" today.

Nice client placement, Teachers Pay Teachers publicity team. You've pulled off a real coup, getting a fawning article in one of the largest news websites in the country.

Poor news judgement, Buzzfeed editorial team. You've taken a handful of wildly successful and unverified samples to make it seem like this is a trend or widespread occurrence among professional teachers.

These two quotes stood out in particular:

School administrators have largely been supportive, too

Henry said her Instagram can help students and their parents connect in a more natural way and have more meaningful conversations about what they’re learning in school.

Really? Administrators have no problem with school facilities being used for this purpose, and parents think sponsored Instagram content is a "natural" way to connect?

I have kids in our local public school system and follow teachers and administrators who use social media channels to share events and special learning experiences. I am also well aware of the struggles to pay for supplies, and have paid the extra fees and donation requests when they've come up. But using these channels as a personal side hustle would be really disappointing, if I learned it were taking place at my kids' schools.

This article does a disservice to the profession, IMHO.
I had some exposure to VHDL, but only from a workshop I attended and it wasn't really any more than you could get from watching YouTube tutorials. I prefer Verilog now anyway as it's way more concise.

The best place to start is to just grab a book and an FPGA kit and go. You'll probably have to try a bunch of tutorials until you find one that clicks for you and after that it gets easier. For iCE40 you can also check out IceStudio, which is a graphical block based IDE that can be helpful for getting your feet wet. Get some hardware to give you feedback and play with, e.g. a 7-segment display and implement a driver yourself. Watch YouTube videos to get an idea of the general flow of things and eventually it'll make sense. IMO it helps a lot if you have a background in electronics, if not you're gonna be in pretty deep.

I use apio because it's convenient. Hardcore FPGA devs are going to use the manufacturer's IDE. The official Lattice tools for the iCE40 are unbelievably awful and there's not much to gain from using their iCECube2 IDE versus open source ones, but in most cases you don't have any choice in the matter and have to use the manufacturers tools. This isn't so bad though, I've had some exposure to Xilinx's ISE and Vivado and they are pretty decent, plus Xilinx gives you access to a ton of free IP cores that you can drop into your design.
FPGAs can have hardware parallelism. And not some specialized SIMD instructions, but the one kind of parallelism you need.

FPGAs can have deep pipelines, so instead of taking data from the memory, working on it, storing it back and moving to the next, you can take serial data, process it in multiple stages and only writing to memory at the end.

FPGAs can have deterministic timing (with a clock). So you can synchronize stuff in parallel, you can have it respond in nanoseconds, you can follow a signal without losing any sample.

FPGAs can have complex pipelines, so you can take an earlier response from the system, but continue processing your data for a more elaborated response later, without performance loss.
