I'm not an expert on these things, but it seems to me if you're implementing a database in Java you wouldn't want to keep your data on the JVM Heap, as this seems to indicate. My understanding is that in most applications (like servers) the average object lives for a very short period of time, and most GC implementations are built from that idea. But, in a database, especially an in-memory database, the majority of the objects are going to live for a very long time. That makes the mark phase of GC a lot more expensive, puts more pressure on the generations, etc.

Is my guess here correct, or are there things I'm missing or mistaken on?
Get a good style guide, read it, and stick to it. I like the Dictionary of Modern American Usage because its recommendations are presented with justifications.
Which were the great UX ideas? I think I missed them... The fact that you had to move your head or phone just to see the time was bad. The 'peek' gesture which required moving your head to the side and looking sidelong at the phone to open a side navigation menu was equally lame.

> Your system makes two assumptions that have been thoroughly, repeatedly proven wrong:

> - It's possible to know what tasks are required to complete a project at the outset of a project.

Contrariwise, if you can't know what tasks are required to complete a sprint, your team is in deep shit. You can get a decent picture over a time horizon of 1-3 months, with certainty going down as the time horizon gets farther out. This is why Agile works.

> - It's possible to estimate how long those tasks will take to complete.

This is part of why you need to capture estimates and actuals. Even if those estimates are wrong, in practice, by comparing estimates to actuals by each developer, a picture will emerge of how far that developer will overshoot or undershoot their own estimates. Those estimates the become actionable data, even if they're wrong 100% of the time.
The bottleneck for DDR memory isn't really the memory controller but rather the memory bus itself. Moving the controller won't change that.

Its very rare to get anywhere close to 100% bus utilization. HMC's real advance is switching to independent serial links which we know how to scale better than parallel busses. Its this improved bandwidth that allows you to pack in more parallelism. We could have more banks in traditional DDR memory but there isn't much point because the data bus couldn't feed it.
Parody is very much protected.

And the Rocksandra fork is already ~3500 commits behind master, so upstreaming this will be interesting.

Oh, and the Rocksandra fork is already kind of abandoned - no commits since 2017 Dec. (which probably means this is not actually the code that runs under Instagram.)
I think it's about force and hardness, contrasted against elastic and inelastic collisions.

Either that, or maybe the caustic qualities have something to do with it? I'm not sure of the chemical aspects of the exhaust, but that part is also mentioned in conjunction with the debris accumulation.

We have an article about how these issues are structural and entrenched issues at the societal level and people offered superficial self-improvement advice to someone whose issues appear to be largely from profound health problems, which misses the point entirely.
Yeah, for Rocksandra, we are able to use much smaller heap size, and most of the objects are recycled during the young gen GC.

>Alternately, people who give advice likely experienced similar issues and overcame them.

Think about this like if someone was talking about fiscal matters. If you had someone who worked their way into the middle class telling poor people helpful tips to do the same, what is the chance they are overlooking factors in their success that aren't easily replicated for others or which was more based on luck?

I grew up in the middle of rural nowhere where most my old classmates hold minimum wage jobs if they have jobs. I worked hard to get ahead, but I was also assisted by things outside of my control. Natural talents and lucky opportunities being the two largest ones. Socially it's the opposite.

For example, contacting a stranger to ask for a ride can be as difficult for someone as learning a new programming language. Some can do it with no difficulty, others have a major block. What happens when someone tries a new hobby and realizes they are still isolated, even from the community of others engaged in the same hobby?

Underlying a lot of this, be it for making friends or finding a career, is the issue of learned helplessness.
I think it's because most people in this community (hopefully) see invasive tracking as being a terrible thing, which is why most of us run ad-blockers.
Well, it works for motorcycles. Sometimes I think I should get back into riding just for that reason.
This is the dumbest thing I've ever heard. The reason for having a performance bonus is to reward employees for doing their job well. The theory is that the employees will continue to do their job well, because they feel a sense of obligation for past bonuses, and a sense of hope for future bonuses.

If what you get is determined randomly, and has no relation to your performance, that eliminates the reason for having a performance bonus in the first place.

Bitwarden (password manager) automatically copies the one time pin into the clipboard when you use the password autofill function. It's great for keeping context. Use autofill, then tap/click the OTP text box and paste in the code.

With that said, I'm not sure it's the best idea to store 2FA and passwords in the same system, but it is pretty convenient.
I think it is a bit unfair to call them myths; they are narratives. All stories are narratives, you can't simply dump EVERY fact about a situation. There are infinite facts and details about how a company came to be, and telling the full story is impossible. Instead, we look at the story, pick a narrative we want to tell, and tell it.

You HAVE to do this when telling a story, and all stories do this. While it is true that believing the narrative tells the full story is incorrect, it is also incorrect to say these stories are 'myths'. They are just one part of the full story.

The Economist has good overview of how inequality affects growth: https://www.economist.com/blogs/economist-explains/2015/06/e...

Particularly interesting is the "savings glut" argument. Rich are spending smaller part of their income. As a result, income equality leads to situation where income flows into investments or property values and demand starts to decrease after a while, leading to smaller return for the investments.
The only biases in this straightforward, factual study are the ones you bring to it.

Congrats on your launch! The website looks very impressive, and I hope it goes well for you. Will you be adding support for any other messenger apps (for example, WhatsApp)?
I'm paying that to Comcast for 25mbit. No competition here.
I think we may be talking past eachother. No one can beat FB directly, with a half-decent chance of success. Lots could, with a very low chance of success.

If lots of people can "enter the market" the one of these might succeed. FB is just an example, but I also mean them. Most of these potential fb-killers don't know that they're competitive with FB.

Think of WhatsApp (again, just an example). They entered the market, at an angle. Within a few years, they threatened FB enough to get bought, just to eliminate the threat.

The end result isn't all that heartening, but everything up to that is. I'm not saying GDPR makes this impossible, just worried about the accumulation of these things. Even a handful of reasonable rules could make things harder, especially if they are different in every country. WhatsApp might have decided to focus on a few core markets, and limited their idea to more local things.
It would be great. But I don't think it could happen. The pluggable storage engine would greatly increase the cognitive complexity of the code.

It would be nice if there was a VC that could operate like the stock market was supposed to. You invest in the VC and you get a share out. But that share can be really really small. 100$ or less. And you get an ROI. I've thought about that before but I have no clue how or what shape that would take with my limited knowledge of the legality behind VC funding.

Just throwing in a argument against hardware keys like Yubikey compared to SMS: Phones are good in that that their owners depend on them and will notice that their phone is missing in a relatively short period of time. Whereas lots of people will have no qualms lending out a hardware token indefinitely in order to help a colleague.

It might not tip the balance all the way back so that hardware tokens end up being worse for security - it just goes to show that security is complicated.
Agreed. Also complete sentences.
The Connect America Fund is funded through a special tax on telcos: https://en.wikipedia.org/wiki/Universal_Service_Fund#Connect.... It's likes taxing cell phone companies to provide free phones for low-income people. Yes, some cell phone companies will end up getting "subsidies" but companies like AT&T (or Apple) would be net payors. And whether or not you call that a "subsidy" in rural areas, everywhere outside of rural areas it's the opposite of "subsidized." The taxes that pay for CAF make service in urban areas more expensive, thus decreasing demand and revenue. Municipalities also treat telecom service as a revenue source (a tax of 5% of gross revenue is typical). And there's all the extra obligations, like build-out requirements.

There was some tax dollar funded subsidies in the ARRA, but it's a vanishingly small fraction of the trillion+ dollars invested in telecom infrastructure in the last few decades.
I'm not on Facebook, but from the outside, it sure looks like pure evil. A tool for the state and other powers that be to gauge the pulse on what is culturally acceptable so they can further shape the narrative of underlying agenda. This one was a miss, but someone is up to something and I'm sure this will re-surface in the future after more time spent blurring the lines. Maybe an army of bots and shill accounts promoting a catchy hashtag aimed at 14 year olds as the new grown and sexy.

We deserve better. Let's build tools truly focused on the community and the well-being of those who participate to better connect and uplift the world around us.

I suspect it's to some degree bollocks, but it's also potentially a testament to the low electricity usage of Icelandic homes.

With the exception of the Westfjords, almost all Icelandic homes and businesses are heated by geothermal hot water. There's such an excess of heat that it's often pumped dozens of kilometers through pipes of varying insulation quality and the heat loss over that distance is still more cost efficient than electricity. They also keep the streets downtown ice-free year round with the extra heat, and dump some of it into a beach behind the city to keep it warm enough for swimming.

Anyway, Orka could be playing with their numbers in order to make sensational statements. Tactically not mentioning the hot water, often the majority charge on a residents bill, would make Icelandic houses some of the lowest energy usage in the world. Pretty much everyone else uses electricity to run their climate control devices and often to heat their home hot water, so no real surprises there.

By contrast, some amount of air conditioners are required to cool data centers even in Iceland. Factor that into your mining cost despite the fact that in a data center doing other things it would be running anyway, and voila, there's your difference. I doubt that much power is going through transistors.
> Pony uses a single message queue for each actor (which is completely invisible at the code level) and typed messages (which syntactically look like functions).

I totally agree with this definition but believe that it leads to awkward programming. The problem stems from forcing the message queue to be FIFO, which does not always make sense. I think the Erlang style selective receive is the correct abstraction, as it avoids having to maintain a separate queue in userland.
I understand why Pony didn't go down that road though, we have a lot more shared experience in type systems for function calling compared to message passing.

We do want to contribute our work back to the Cassandra upstream, instead of keeping it as a fork. So that more users from C* community can benefit from the improvements.

That's pretty wishful (or perhaps naïve) thinking. A family member of mine literary hasn't spoken to me in over two decades because I told her I didn't believe in god when I was 12. She asked me out of nowhere, I said no, that was it, I was no longer to be in her life in any capacity. She also tries to meddle in my business telling other people I am not to be trusted because "you can only trust someone who fears god."

Its been my experience that most people who are devout enough to go to church are exactly the "convert or leave" type. Church is a very tribal place.

Not to mention that the type of people who want to spend their time doing church activities are people I find horrifically boring and have ZERO common ground with. May be less so if you're male.
The reason they're faster isn't so much that as they're geographically more direct. The older fiber networks were already pretty optimized for latency at the network level to the point that the last place to make any real gains was physically shortening the connections. That's hard with fiber because you have to get agreements along the whole route to dig and bury the fiber where microwave links only need periodic installations.
You can play with this in browser.[1][2][3] And there's OpenCV.js.[4] But I more often simply put a small square of yellow gaffer's tape between my eyebrows, and do color tracking.[5] Accurate, reliable, and cpu/battery cheap.

And for expert UIs, one doesn't have to emulate reality. So you might exaggerate parallax, be non-linear or discontinuous, etc. There might be a much larger vocabulary available, than merely "look through the small portal" and "make secondary content conditional on viewing angle". Maybe.

Why might you want this? Consider your primary "desktop" environment shifting into HMDs. But you still need to mix in screen time, to give your eyes a break. It would hypothetically be nice to have similar UI idioms on screen. Especially as your tooling becomes less and less like current 2D ones.

Ethics. Which means I'm hypocritical right now.
However you're defining focus I'm sure correlates pretty well with the personality trait conscientiousness. (IQ is the best single-variable predictor of nice things like life success, for various definitions of success, IQ + Conscientiousness predicts even better...)

The purpose of separating into young and old generation is that it's easier to find dead objects in the young generation (as you said, average object lives for a short period of time). You only have to scan this subset for a minor GC. It doesn't really matter how many long-lived objects you have as long as you can avoid needing to do a major GC.
> Your system makes two assumptions that have been thoroughly, repeatedly proven wrong: - It's possible to know what tasks are required to complete a project at the outset of a project.

At some point though, once you've decided what tasks to work on, how much they cost (in time, dollars, risk, etc.) is a very important question. The answers will always be guesses, but tracking what actually happens over time helps to improve future guesses.

> - It's possible to estimate how long those tasks will take to complete.

One cannot eliminate all uncertainty, but it is possible to decrease it over time. A way to do this that I found works well is to look for past tasks that are sufficiently similar in size and complexity to the one being estimated and use the tracked data to anchor the new guess. You track as you go in order to build this log.

I should emphasize that I think this data should be there to help developers improve their estimating abilities, and not for the management to judge developer performance.

> Furthermore, "if it can't be measured, it can't be managed" is true to a degree, but over-reliance on metrics can result in tunnel vision towards those metrics, resulting in accumulation of technical debt, quality issues, less team cohesion and a host of other problems as your teams myopically focus on hitting their numbers above all else.

Very true. However, never measuring or logging anything out of a desire to avoid the things you've enumerated can deprive a team of valuable information and lead to missed learning opportunities. The trick is to find the right balance.
All that energy and money could be put into good governance and public programs. It has worked before.
