Bigtable and Cloud Datastore (or the newer, shinier Firestore) are very different, and meant for different purposes.

Bigtable is meant for wide-column data at high volume. If your data can be organized into simple rows and columns, and you plan on using massive amounts of it at high throughout (think IoT transactions, for example), then bigtable is the right choice.

Datastore, on the other hand, is for semi-structured data, with parent/child hierarchies, key value pairs, etc. It isn't run on a cluster of nodes like bigtable, but is managed behind the scenes as part of App Engine. It is slower than bigtable, but is more sophisticated, and offers client libraries for ORMs (ndb), SQL-like queries, and the like.

There's a brief comparison chart here:

I also highly recommend the Google cloud data engineering course at Coursera:

Siddon Tang from TiDB here. Thanks for your interest in TiDB!
TiDB uses Snapshot Isolation (https://en.wikipedia.org/wiki/Snapshot_isolation), which is similar to Repeated Read in MySQL. It doesn’t allow Read Phantom but can’t avoid Write Skew. IMO, this can work well for OLTP in most of the cases. If you really care about serializability, you can use `select for update` to promote the Read as Write explicitly like other databases do.

TiDB supports READ COMMITTED isolation which is not the same as MySQL, but it is just designed for some special cases for TiDB itself and it is not recommended for external users.
Why outcompete? Why the need for a quasi-monopoly? Why can't half a dozen companies work a market in competition and create better products for everyone? Many problems with Facebook and Google come from not it outcompeting other companies and making things worse for society as a whole.
But this is a pretty predictable result of having privately owned services like this be such a big part of the Internet. MailChimp, understandably, doesn't want to be associated with this content, and they are under no obligation to allow it.

The problem with that is rotating schedules is more economically efficient than loading all the class-types onto one time of the day. This would mean you need more PE teachers in the morning, more math teachers in the mid-day. There's a reason schools have multiple periods of each course, and that those periods rotate day-to-day.

One interesting follow-up study could be to compare night-owls/morning-larks in rotating schedule schools vs schools with fixed schedules. We could then see do night-owls do significantly worse in the classes they only take in the morning, vs night-owls who take classes rotating throughout diff periods of the day?

>Is one a day already addiction?

Absolutely yes. I have only a cup of coffee (or the equivalent caffeine via tea) per day and get killer headaches if I skip a day. Whether this is okay or not, I'm not sure. I usually see articles saying three or four hundred milligrams is okay, but that seems like a lot to me (that's a few cups a day depending on how you measure your cups).
"Magic Leap Inc. has quietly begun sending its mysterious augmented reality headsets into the wild. A small group of software developers recently received devices at their offices, according to people familiar with the matter. But access to the gadget comes with an unusual caveat: They must commit to keeping them in locked safes."

Let me explain how this works as a marketing person. You create hype for your new thing any way you can, for example if you ask developers getting the device to put it in a safe, all of a sudden you keep yourself in the news, because its stupid. and the news media loves stupid and strange things, they get people to click on it and promote it on HN.

I am not saying this wont be a great device and im excited for this product honestly, but artificial hype like this needs to be seen for what it is. Let them prove their product through its actual technology, SDK's and consumer love, then we'll see.

I wish Magic Leap all the best!
Fairly capable private investigative and security forces are pretty common for tech companies now. I am not surprised Facebook falls into this category.

Google's is run by a guy named Brian Katz, who's been the subject of a lawsuit before: https://arstechnica.com/tech-policy/2016/12/anonymous-google... and the very same has allegedly threatened a bartender who found a prototype Nexus 4: http://www.dailymail.co.uk/news/article-2224589/Google-threa...

Apple security folks have tossed a guy's home looking for a prototype iPhone, escorted by police. All of them, allegedly, had badges: https://gizmodo.com/5836990/lost-iphone-5-investigators-were...

They obviously can intimidate employees into silence, but it's far more useful and beneficial for morale to go for the "loyalty" angle, and make sure employees shame others who leak.

The thesis of the memo couldn't be written any other way?

I think you could write about the ideas contained in Boz's memo in such a way that if the memo leaked you still wouldn't look like huge bleeps.

It's not the conversations that are getting them into trouble. If it were just this memo, then nobody would care.

Their action are getting them into trouble. Leaking memos like this merely offers a window into their souls.
Because otherwise your comment makes no sense. You can already get satellite data rates (100Mbps on a home plan) equal to or greater than LTE, from ~100 times further (36,000 km altitude Geosynchronous orbit) and the distance itself does not fundamentally limit the speed, but the latency there is terrible and is fundamentally limited. LEO satellite constellations address that.

SpaceX's particularly large constellation (allowing streaming from multiple satellites at a time and with large phased array antennae on both ends) will allow much higher bandwidth than existing satellite internet systems, but the biggest deal about these LEO satellite constellations over GSO satellites is the far lower latency.

I would prefer 0 days in prison because I don't think voting while a felon should be a crime. But, if we still want to call this situation voter fraud, how about we sentence them to community service? This person is not a danger to society, so I see no reason to put them in prison. More prion just messes up their life further and costs everybody a lot of precious tax dollars.
Are there no filesystems which address this issue? What challenges are involved? Does hardware support safe append-write filesystems? Why/why not?
Thanks for the advice!

You're right: scientifically/formally speaking this cannot be considered an experiment but, in my opinion, for small and easy-to-change processes, there is no need to be formal. The goal sometimes is just to solve small pain points and make people happier at work, and in such cases the fact that people perceive that things are better after the experiment could be enough :) Obviously, this was just a simple case study and every perceived improvement could be due to confounding factors, as you say, or just to the fact that the experiment created awareness about a problem. Obviously, if an experiment touches something more relevant than slack messages, being more formal is a good thing and A/B testing is for sure a better approach.

The point of the post was just to make people aware of the fact that changes in a team can happen without too much pain and that continuous improvement and experimentation are processes that can be implemented easily.
Prison guard unions and private prisons are effectively the same thing. They are both groups that directly benefit by increasing the prison population.
I'm not seeing it. Can you elaborate?
Kind of, but the legal system is tilted to prevent people from being unjustly imprisoned, not to ensure that every guilty person is locked up. Prosecutorial discretion and the grand jury process is part of that, but there is always a regular jury as a check to determine if the charges should be dismissed and the "default" if no one does anything is always no charges.

Now, its fair that in practice this can be abused to protect people in power by not charging them, or to get people deported by charging with things no jury would convict on, or scare them into a plea deal. But that is where the political system is supposed to step in (most DAs are elected) and remove prosecutors who are making decisions the voting population doesn't like.

But people don't vote (or don't research or don't care) enough to be an effective check on the legal system like that, which is a whole different set of problems... but my point is that these systems are designed to balance each other, not so that each system is perfect by itself.

I'm going to use this opportunity to get up on my soap-box and talk about helm, the "recommended" way to install kubernetes packages.

Helm is not a useful abstraction, and needs to change in a BIG way before I consider using it over k8s_raw and ansible.

My main complaint with helm is that it doesn't allow one to develop decent abstractions over the core kubernetes resources. IMO it needs to move away from `gotpl` and implement the ability to use more sophisticated templating libraries.

I think this block of text elucidates my point:

```

metadata:

name: {{ template "drupal.fullname" . }}

labels:

app: {{ template "drupal.fullname" . }}

chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"

release: "{{ .Release.Name }}"

heritage: "{{ .Release.Service }}"

```

This block of code is in every single resource in every single helm chart. And it's one of MANY similar blocks of code that appear in basically every helm chart. I do not particularly enjoy writing the same massive YAML file over and over again.

Configuration management with helm is difficult. It would be nice to be able to declare "required" fields within an application, and enforce those fields with an error message if they are not provided. Currently, there is no way to do this other than having a "required" template that iterates through your "requiredFields" field and calls `{{ .Values.fieldName | required }}`

Interacting with the helm API server is difficult, which makes integrating helm with other configuration tools difficult. Specifically Ansible. This is also partly k8's fault ( And my fault, I suppose, because I could write it myself... ), because port-forwarding into the k8 server isn't implemented in any languages other than GoLang.
It's not about growth. It's about money. And to get that money, some companies/executives are OK with harming anyone that gets in the way.
Ahh, but the article didn't say that people need Facebook. They said that we need an alternative to Facebook. That's two different things. If people are going to use Facebook (and it's been shown that people will) and Facebook use is going to cause systematic problems (as it's apparent that it does), we may need an alternative to Facebook that is less problematic. That's a very different statement than the one you're responding to.

I definitely remember it differently.

Dean Kamen is a very sharp inventor, and the origin of the Segway was in a radical wheelchair improvement that he designed. (It was a four-wheel design that would "stand up" on its two back wheels to give the user similar height to a standing person. It could even climb stairs! [1])

A lot of the hype came from luminaries who had seen or tried the Segway and were opining on it themselves. The technology was really neat, and is cool to use. At the time, it was plausible that it might change a lot. In practice, though, it turned out to be mainly a niche product, because we already had pretty good solutions for getting people from place to place.

And that last bit is important. It didn't completely evaporate. I often still see a flock of Segways for guided tours when I'm in Golden Gate Park. Segway still exists, and is still producing a variety of models.

But you're right that the hype got out of control, and the vast difference between expectation and reality harmed Segway's brand. That could definitely happen here.

Yup!

Every person is a little different. One of our kids is definitely very alert and ready to learn in the early morning. The other one, unfortunately, isn't. The one-size-fits-all schedule is much more for the convenience of adults than for the effectiveness of education, unfortunately. Some of the other commenters point out that important things should not be too early or late. That may well work better. But I'd be a little worried that there is no such thing as one good schedule that works for every child or even a significant fraction of children.
I don't know a ton about hockey either, but apparently goalie is more analogous to kicker or punter than "regular" positions in football.

Even so, in the case of a kicker/punter injury a NFL team wouldn't call someone out of the stands to fill in - they'd sign someone out of free agency to play the next week and would adjust their strategy accordingly during the current game.

It's really cool that pro hockey has a unique system in place for edge case situations like this.
Calling crimes "mistakes" is a terrible euphemism.

It may be accurate in some cases. But many criminals commit their crimes knowing full well what they are doing, and with no regard for those who are hurt by their actions, and show little or no remorse (unless they think pretending can reduce their sentence).

Now, many are in prison due to unjust laws, selective enforcement, or a flawed prosecution incarcerating the wrong person. But let's not lump those problems together with those who intentionally harm others without remorse.
If you're arguing against having probation you're arguing for longer time spent in prison.

Not necessarily.

I don't think we've gone back to it, it's just taking us longer than we expected.
The hockey goalie is an interesting role because it is a very specialized skill relative to the other players, and typically done by the same person for most of a season, with a backup that plays maybe 10-25% of games.

I think the closest thing would be a pitcher in baseball, but even there, it's hard to imagine an injury scenario that would result in an amateur being put in, because there are so many relief pitchers, and others not in rotation that could sub in.

It's fun imagining this attitude applied to the Space Race.

>So we go to space.

>That can be bad if they say accidents happen. Maybe three of our guys die on the launchpad. Maybe a spacecraft is lost on recovery.

>And we still go to space.

>The ugly truth is that we believe in going to space so deeply that anything that allows us to go to space more is de facto good. It is perhaps the only area where the metrics do tell the true story as far as we are concerned.

>That's why all the work we do in space-going is justified. All the pure oxygen environments. All the hatch designs that can only be opened from the outside. All the ad hoc procedures and cheap wiring. The work we will likely have to do on the Moon some day. All of it.
I posted about my situation and difficulty finding a job on another social media website, and a commenter wrote "Those lists exist for a reason. You made your bed now sleep in it." That's literally what the public thinks they're for, as a permanent form of discrimination and condemnation to prevent people like me from having a job or a good life. It's meant to keep us down all our lives.

If that's what the voting public thinks it's for, then for all practical purposes, that's sure as hell what it's actually for.

Many people feel that probation is inherently unethical. X years of probation seems less harsh than X years in prison but often amount to the same thing.

Without the option of probation prison time is not going to increase 1:1 and depending on the ratio total time in prison may actually decrease.

There's also 'fairness' in law - so you have to serve a sentence similar to others guilty of the same offense. And yes in this strawman case your sentence should perhaps not be a long one.

Except the sociopath angle - a person who commits crime for fun is quite likely to find another fun crime to commit.
It is based in a competition called Speed-Memory a discipline called shapes and colors. With different velocities you can use different memorization techniques. For example First 6 shapes 1.7 seconds per shape you can use element associations (each element is image) example red square a missile white triangle ice cube (a missile explode in a ice cube) . Next two pass more quickly you use a iconic memory (only see the image). Next five (more quickly) you can use phonological loop (only say the name of the image) las two the most rapid passing figures you only see it as a photography of the shape) when the test finish you first respond the las two figures (that are in your eidetic memory) then the phonological loop and the others...

With this system you can use the different forms of mental processing of the mind.

Here the code of veolocity calculation equal to the speed-memory

count word is (0 to 14)

_n=velocity;

if(countWord>=3)
_n = _n + _n * 0.2;
if(countWord>=6 && countWord<9)
_n = _n + _n * 0.4;
if(countWord>=9 && countWord<12)
_n = _n + _n * 0.6;
if(countWord>=12 && countWord<14)
_n = _n + _n * 0.8;

velocity=_n;
