Ask HN: 2.5 years old twin boys not showing enough progress in speech
I am father of 2.5 year old twin boys. There are many kids of same age around me and I noticed that all of them have reached to some level of speech progress but that is not the case with my kids. In fact, kids' speech level is not even comparable to a kid who is slightly less than 2 year old.

Except for this concern, they are perfectly healthy and mentally alert. They show no other sign of any kind of trouble. Their hearing capacity is pretty good and have no trouble in understanding what is being said to him. They also learn doing things without much trouble/effort.

One of the twins do blabber a lot but rarely something meaningful. Although he is showing some promises as he started to use words like 'bye' and 'i love you' (he blabbers when it comes to 'love'). He also tries to count from 1 to 10.

The other one doesn't blabber that much or occasionally use some fixed (and usually incomprehensible) lines. Though both of them try to talk with some gestureing.

In general, they are lagging far behind as compared to other kids in speech related matters. How do I deal with this issue?

Edit: Per doctors, this is not a serious issue. They say it is only a matter of time and some kids start speaking a bit late.

It is a widely-held belief that searing a piece of meat before a slow roast will seal in the juices. Actual testing reveals this to be completely incorrect.

Searing (dry, high heat) produces maillard reactions which are responsible for lots of flavors that we like. So searing is good, but it's better to cook your meat to just below the temperature you want, then take it out and sear it. You'll have a more consistent doneness.
Thank you.
I appreciated especially the pattern matching feature of C# 7 while programming the interpreter.
For example:

switch (x) {
case Arg xarg:
return xarg.GetValue(env);
case Sym xsym:
try {
return Globals[xsym];
} catch (KeyNotFoundException) {
throw new EvalException("void variable", x);
}
case Cell xcell:

Same thing for us Amiga-owners. While the Amiga had pretty decent sound/graphics-capabilities in the early 90's, expanding the computer with something like a hard drive (which wasn't standard on the smaller models), or more RAM, or video processing hardware, was simply mind-blowing.

An indirect way of encouraging this is including kids in what you are doing, as opposed to engineering activities for them.

A lot of kids' world these days is an artificial reality, made for them. School, soccer, art class, play dates. The reason the activity exists is to give kids an experience. We're not interested in it, because it's kid stuff.

When I was a kid, some of the most formative activities were fishing, sheep farming & vegetables gardening (grandparents on a farm), home repair jobs like painting or brickwork.

When I was very small (2-4), if my parents were painting a room, I was also in old clothes with a paintbrush "helping". Same with spring cleaning or whatnot. I had a little hammer I could bang, to help my dad assemble IKEA furniture.

You don't have to conciously "engage" in their stuff, just let them engage in your stuff.
I’m aware that they’re low cost, they’re everywhere in sydney. I guess I just am trying to look at the unit economics and reverse engineer the business fundamentals. The bikes came before the users, and i guess even with a couple thousand (probably high end numbers now I think about it) bikes in sydney, Melbourne and then 10s is thousands (if that) in Singapore they could do it with a small capital base, especially with almost no support on the labour side.

Then again they ended up having to spend a lot of money in Melbourne cleaning them up which would have buggered their modelling.

Bottom line of my comment above: the bikes has to come first with a reasonable lead time before the deposit. I see now that they could have borrowed against it as well but it doesn’t look like they had large inflows of PE or VC money?

The following is purely my opinion.

Rust might have gone too far the other way. Yes it strives to be a modern language, with a lot of functional programming features and "OOP" done right (aka no inheritance, simply method polymorphism). To me Rust is more a C++ replacement than a C replacement.

A replacement for C should try to be as simple as possible while fixing C weak typing mess with strong typing for instance, including when it comes to pointers (for instance like in Ada where you can't just take the address of anything you want, you need to declare it as aliased to begin with). In fact Ada tries hard to make pointers redundant which is a great thing. This and range types and bound check arrays( Ada has a lot lot of great ideas, and "C style" Ada is a treat to use).

So a C replacement should keep the procedural nature of C, with closures perhaps, but not go further in terms of paradigm. C aficionados often claim they love C because it's "simple"(it isn't) That's what they mean, they love C because you can't really do OO with it.

On the other hand, Rust macros are exemplary of what a good macro system should be.

The certificate system is broken. Technical people should not be promoting centralization, raising barriers to publishing and empowering middle men. That is not a technical solution, but behavior that favours business and vested interests.

There is now a clear pattern of attempts to raise barriers and cede more control to actors in the middle.

First it was de-legitimizing http, now its standard certs, then it will be 3 years. What's stopping this degenerating into an elaborate 'approval process' from a central authority in a few years which you pay dearly for, all in the name of security?

This kind of control gives some the power and fig leaf of any 'arbritary process' to delegitimize and silence others.

Ask HN: Looking for a simple solution for building an online course
I want to build an online course on graph algorithms for my university. I've tried to find a solution which would let submit, execute and test student's code (implement an online judge), but have had no success. There are a lot of complex LMS and none of them seem to have this feature as a basic functionality.

Are there any good out-of-box solutions? I'm sure I can build a course using Moodle or another popular LMS with some plugin, but I don't want to spend my time customizing things.

I'm interested both in platforms and self-hosted solutions. Thanks!

I'm saying that it very well could have been intentional, yes. Not in the sense of somebody at Google targeting Blender specifically (that's possible but seems very unlikely), but in the sense of somebody at Google trying to see how far they can push forced monetisation through algorithmic coercion.

Blue LEDs are a relatively recent thing, we’ve had decades of green and red LEDs on our gadgets and I’d expect the trend to balance out over time. RGB seems to be going through it’s thing and at least if you’ve got an RGB keyboard you can dial in whatever hue you like.
So the toilet cleaner retrains to become the toilet repair person? What's wrong with that? We all get better toilets out of the deal, too.

One thing I don't see people mentioning too much, but tesla numbers are great for electric cars, but they're tiny, tiny compared to something like ford. I don't get why people assume tesla can negotiate similar prices for these things as other manufacturers can. I don't think they can. Who says it's cheaper for tesla to order like the big manufacturers do?
If consumers don't show a willingness to pay for skilled employees, then it isn't an asset. In low margin, low skill businesses such as retail for everyday items, there simply isn't much value to be provided other than stocking shelves, keeping the place clean, keeping an eye out for theft, occasionally telling people where things are, and scanning items at check out.

I stay at Hilton hotels and they frequently have digital keys that use phone to open the hotel door. I don't even interact with any staff, just use the app and I'm out and in at my own leisure. Some businesses are just skirting the line between do we invest in employees or automate things, and of course automating things is the preferred option.

We have a bike sharing system in my city, but one must always return the bike to an automated bike rental station where the bike is locked. This is how it works in London as well AFAIK. A bike left just somewhere is a violation of the service terms and a penalty comparable to the fine for riding public transport without a ticket is charged from your credit card.

I can understand why bike rental system without proper stations where the bikes are stored would be considered corporate littering.
I would argue the opposite. Especially for Macro. I'd argue that any econ 101 teacher that doesn't consider politics shouldn't be taken seriously. Ignoring political realities is precisely what is wrong with a lot of (but by no means all) economic reasoning in our society.
What the. I thought I recognized that book instantly upon seeing that preview of it and skimming the article, but the fact that it had been released only a few years ago made no sense to me--I was sure I'd seen previews of it something like 15 years ago, and then I suddenly remembered, vividly, how eerie it had seemed at the time, and I remembered being in this same house I'm in right now, looking at it online and feeling weirded out. But just now, after more reading, I found out the book is based on some earlier and similar black and white pages he'd drawn back in 1989 for Raw magazine, which must've been what I saw online 15 years ago.

So basically the last 10 minutes of my life have been super weird and totally appropriate in the context of that dude's work. Gaaah. Thanks for the link, and the bizarre meta experience I just had.

It would be fair if they would provide accurate weekly production numbers for the last 6 consecutive weeks. Maybe the pattern was: 3000, 2000, 1000, 1000, 3000, 7000... Which is quite different than pattern: 3000, 3000, 4000, 5000, 6000, 7000...

It is amazing to me that colors of instrument readouts is not regulated, when the research is extremely clear that red and orange (and yellow) are much better for night vision than white, blue and green. Add to that the huge screens in most cars these days and you have a recipe for night blindness caused by just looking at your infotainment screen for a second and not seeing a pedestrian due to the ghost image left on your retina.

Just because humans can replicate it does not mean that the rules can be expressed in any useful way. Plenty of tasks that replicate easily across humans (such as driving) currently are not automated.

How to ask a stranger on the internet for help
I have a hatred of blue LEDs on household equipment, they always seem to be significantly brighter than their red/green/orange counterparts.

For example: If I need to leave my computer running overnight running a job, I have to tape over or block the power button in order to get a decent night's sleep as it has a nasty habit of utterly illuminating the room - the hard disk activity light is much more tolerable.
I'm not sure I can agree with that comparison because physics, even quantum mechanics, are a still considered a natural science.

Economics, on the other hand, are usually considered part of the social sciences, due to the heavy sociological influences, which make modeling, predicting and testing extremely difficult.

For all the talk of "the market", especially in the financial sector and by glorifying certain successful individuals, the reality seems to be far less understood than many people would admit to. Probably has to do with these people usually trying to sell their services/financial products with a reputation for "understanding and mastering the market".
Glad to see someone else confirm my thoughts.

Maybe the whole industry can reach the true typing nirvana: that Dell keyboard, with trackpoint.
the comparison at the start is nonsense - there is no specification for the ordering or location of stack variables. by taking the address of these variables, you could see that they actually are the same value, and so intuitively you’d think they might be the same, but a different compiler might put them in different locations. or they may be elided entirely through optimisation. it’s far safer to fail the equality test in this case - this is what the model specifies.

this is not even the first example of this counter-initiative behaviour. imagine two floating point values with exactly the same bit-representation. it is possible, without any trickery for them to fail an equality check - i.e, they are both NaN.

this is what IEE754 demands of a compliant floating point implementation. and indeed, it’s a sane choice when you understand why it was made.

similarly, it’s perfectly reasonable for this example to fail.

I just got back from Portland Oregon and used biketownpdx.com several times, it was fine. The only issue was that the bikes were heavy. $20/mo for daily usage was great.
115 bits of security is pretty good, for example 3DES, while not exactly a great choice today, is still considered secure and acceptable for use today, with its 112 bits of security. However, I know of no public key encryption scheme that would give acceptable security with only 115 bits of public key. With RSA, you need at least 1024 bits, and probably should rather use 2048. Elliptic curve cryptography is considerably better here, but an ECC key of length n stil gives you only n/2 bits of security, which would be way too little here.
This seems to be the implementation: https://github.com/wuxb45/LMDB-SLB

Looks like it is effective for small data sizes and pure read-oriented workloads with heavy key distribution. Not sure whether this could work well for writes and uniform random distribution.
