NOTE: I am on the product marketing team at CockroachLabs.

Cockroach Labs has been building CockroachDB for over five years and has reached a level of maturity where many enterprise and community customers are gaining value from the database.

We consider it a cloud-native database as it was architected with the same principles as a distributed platform like Kubernetes. It is built for scale, resilience, is shared-nothing and is comprised of a single binary across all nodes with consistent API. We have also gone to great lengths to ensure it is wire-compatible with PostgreSQL and implements a large portion of standard SQL syntax. \It is used as a relational database.

The key points we typically talk about fall into four key areas, that we lovingly refer to as CRLS (an acronym for Cockroach Labs)

Consistency - the database implements serializable isolation across distributed nodes within a cluster with acceptable latencies even both local and globally dispersed deployments.

Resilience - the database replicates data across nodes in the cluster and you can configure this to survivability at the table level for optimization of a loss of a node, zone or even region. It is an active-active system that is always on and data is always available. Further, you can implement online schema changes and rolling upgrades in production without downtime,

Scale - scaling the database is accomplished by simply spinning up a node and pointing it at the cluster. The database will take care of redistributing replicas to incorporate the new node. This is basically auto-sharding and adheres to the aforementioned policy of survivability mentioned above.

Locality - Unique to CockroachDB, you can also tie data to any particular node in the cluster. You define this at the table level. The database uses KV at the storage layer to accomplish this. Each table is represented as ordered KV pairs using the PK for the table for the Key. You work the location into the key and the distribution policy will ensure data is written to explicit nodes. This is used to ensure low latency access of data and/or to tie data to a location for compliance and privacy requirements. With online schema changes, you can manipulate the PK in production and rearrange where data is physically stored in a live production cluster.

There are numerous other capabilities in the database. We have a complete UI, deliver distributed backup/restore, change data capture and have implemented a cost-based optimizer that uses locality.

It is a relational database that you can deploy the database as a service on kubernetes and or in any cloud.

There are countless more capabilities and we invite you to check out one of our features we are most proud of… our documentation!

Also, please check out customer page - yes, these are high level but there are some stories there.

Biometric "security" on phones is a gimmick.
There would be decreased costs for the entire house as you then no longer need a heat pump in you fridge, water heater, etc if you tried to emulate current hot/cold use. If I designed the system, it would just be a hot and a cold loop that goes throughout the building, with a standard outlet that had both the hot and cold lines present.

For residential, you could install faucets that had a internal heat exchanger that would let you have actually cold or hot water for cheaper than a traditional on-demand water heater. HVAC would be better as individual control of the heat for each room wouldn't add much extra cost, so your south facing rooms can get more cooling without having to freeze everyone in the other rooms.

For restaurants, the system would be particularly attractive as they can have heated/chilled food holding (and work surfaces) and they would be able to be swapped between the two by flicking a switch, so the winter menu (or the lunch menu even) could feature more hot items, and the summer (or dinner) menu more cold things without wasting capital (and space) on equipment that isn't used all the time.
Similar to the Wirecard harassment story, just recently.
It's been a few years since I've followed vertical farming, but I have recalled an argument being made that an artificial light source can be made efficiently by using a single-wavelength, super-efficient LED with a specific color that stimulates photosynthesis.

On the other hand, I've also read (old, long-lost) sources that state that the energy cost per loaf of bread is about $10 for indoor farming, vs $5 for outdoor farming.

These specialized lights won't save vertical farming today, but I will keep following the progress. If nothing else brings value to vertical farming, the fact remains that local food independence is valuable; growing food in a dense apartment or a dense city will pay dividends in the event of large-scale famine or civil unrest.
Why is energy density important in that context? If all other variables were identical between a high density an a low density solution, the high density one would of course be preferable. But if the low density solution is cheaper and relies less on pre-existing long-distance grid infrastructure, why would high density still be considered the most efficient, or possibly the only viable pathway?
If you want to program in Haskell, why don’t you get a job programming in Haskell rather than inventing something so ugly?

You would not get through code review with that in any shop that has discipline.

Using data tables to publish websites and apps is an interesting concept and having an in-house tool to produce most commonly requested ones makes total sense. Look at their templates: Inventory management, Team Tracking, Surveys, Reporting...etc. It makes sense.

One hard problem here though, by the looks of it, the tool is a database designed by engineers in response to a lengthy requirements document. It has no regard for user experience, and is one of those things you can use, only if you go through a 3 week training course.

This, imo, is where AWS could borrow from startup playbook, and instead of launching a spaceship, start instead with a paper airplane. Imagine if all you could do was to publish an inventory-management tool, that in one-click integrated with Amazon Pay and let the customers buy your products on a website?

Maybe Amazon is waiting for someone else to build this on top of their tools, and then make it available, but that poses a question why. Why would someone build on top of Honeycode, only to have Amazon eventually make it their own?

Interesting concept, but it's got a long ways to go before anyone needs to be scared of what Amazon can do with this thing.

What's good for an individual family is not necessarily good for society as a whole.
I am actually excited to see this in the wild.

I wonder how well it would work when cell reception is very bad (indoors or 3G)
You're right, goats can be trouble makers. We use sheep to mow our lawn and they are very easy to deal with. They won't go over a 2 foot fence and don't need a lot of maintenance. Water, occasionally some mineral rich feed, and a shear.
You should pay special attention to the section about attestation, which is not something that is done in a privacy-focused way without an anonymous attestation authority (which is part of the iOS 14 feature)
This was the very first thing I thought of when I saw this submission title! Great talk, well worth watching.
I started following that rule a while ago too, I wouldn't trust some random off-brand food from amazon, but the brand name food has a fair bit of markup.

If the counterfeiters are willing to produce anything to make a buck, and amazon is willing to sell counterfeit goods as legitimate, it makes sense we'd eventually have counterfeit brand name cereal or canned goods.

A while ago my fiancee was having trouble finding some Eagle Brand Medicated Oil (it's this traditional asian stuff her mom rubbed on her), and I saw it was on amazon. It's possible they have changed their manufacturing processes slightly since her previous bottle, or it was different because it wasn't as old, but it just kept being every so slightly different in subtle ways, such as the feel of the bottle and even cap, the texture of the oil, the smell was a bit different, the box was a bit bigger, etc.

I honestly still am not sure if it's counterfeit or not, but that's just the issue, I don't have the means to check. My only choice is to buy from sources with trusted supply chains.

It's ironic, I was the first of all my friends to start using amazon excessively, and got them into it, but nowadays my fiancee remarks she found her workout supplement on there for a few dollars cheaper and I reflexively reply "Hell no! We don't put things from amazon in our body.

At this point I only trust them with things that can fail on their own without causing damage, or for products so complicated no one has made a knock-off yet (I'm waiting on knock-off brand name monitors). They went from this amazing cheaper alternative to big-box stores, to AliExpress with 2 day shipping.
I don't disagree. I just find it surprising that anybody said it.
"apps my mom could build" kind of describes Excel workbooks. People effectively use excel to build (highly constrained) GUIs for processing data using custom logic that they specify themselves. And excel's popularity speaks for itself, it's completely pervasive. So that's the answer; the audience isn't programmers, it's the officeworkers all over the world currently using Excel to automate office tasks and want a better delivery mechanism than a shared Excel file on the office LAN. That's such a big pie that even capturing a small slice of it might be a reasonably profitable endeavor.
It is a risk. There's an easier solution, though.

The comments by Marshall’s granddaughter, Jordan Wright, are remarkable.
The blog is problematic. It came out pre-GDPR and doesn't reference GDPR.

It also has incorrect statements: "A simple attestation by the company along with referencing Privacy Shield creates compliance": No, really it does not.

So yes, would advise you to get a real DPO and Art 27 Rep in. They aren't expensive and with CCPA present now too, will likely be a good investment.
You can also do [a, * b] when constructing a list so that b would be injected into that list after a - makes total sense.
It seems my memory is not useful when it relates to google products.
Then there should be a setting that has to be manually approved to allow the clipboard interactivity feature.

I use a password manager on my iPhone and I am copying and pasting my passwords all the time. If some random app is scraping my clipboard silently and sending the data to a third party, that means my passwords are compromised. I am very much NOT OK WITH THIS.

Keep in mind, this permission should be fundamentally different than the permissions for just manually copying and pasting. I don't want to have to deal with permissions to "allow clipboard use" that I have to approve every time I want to paste something. That would be obnoxious. I am only worried about restricting permissions for invisible passive snooping.
The cynic in me assumes they are doing this so they can make Amazon Basics versions of popular counterfeited money and remove the angle that counterfeiters are using...
While also enabling finger-pointing, e.g. the police can say "We aren't racist or aren't at fault. The system is just faulty." while the engineers behind the facial recognition tech can say that they, "Were just doing their job. The police should've heeded their disclaimers, etc."
I have never heard anyone suggesting that vertical farms enabled 3d planting. It simply removes the linear relationship between square foot of land and number of plants.
I'm in my late 40s and say "Wow, Raku!".

I haven't used it for anything work related yet, but working with it is mind expanding and makes me a better programmer in whatever environment I work in.

The type system, multiple dispatch, literate programming support, and command line scripting features are simply amazing.
I think the suggestion is that fusion power here is a stand-in for electricity that is too cheap to meter -- basically free power.
The header sucks on the ultra-wide monitors as you have one set of the buttons on the left side and other on the right while the main content is in the middle.

It completely destroys typical page parsing habits.
Sure. The context is "dumbed down to make it easier to learn" not dumbed down and forced on everyone. If you want to go full Brian Eno, you can. (https://public-media.si-cdn.com/filer/2b/e0/2be067d0-c428-40...)
> Still, JavaScript is the most brittle of all front-end web technologies.

I don't think "brittle" is the right word. I get what it's going for, but thinking back to the jquery days where the javascript was driven by events fired from the DOM instead of a framework, it was actually really robust - when something went wrong, instead of the whole page crashing, you'd end up with just one feature not working while everything else was fine.
My speakers connected via HDMI and monitors w/ HDMI audio did something similar. It seemed like I got duplicate audio devices, depending on which port I used (DisplayPort or HDMI, via an adapter cable or not). The audio driver seemed to get so confused with this it just stopped working.

I had to unprotect a deep registry entry and clear out my audio devices, at which time the relevant entries came back after a reboot. Any normal user would have been stuck with reinstalling.

It’s quite amazing how many “edges” Windows still has. I’m very close to figuring out how I can have a Windows VM w/ graphics card passthrough just for games on top of Linux. It might have warts too, but at least I can fix it.
There are only two measures there that compare Asian Americans to Caucausian Americans,and both are quite sensitive to being reflective of the high Asian immigration innrceent decades selected for highly educated individuals already qualified for work in highly paid fields, rather than Asians succeeding more from a similar starting point. IOW, they don't do much to cast doubt on racism adversely impacting Asian Americans.
> You can only grow non-calorically dense foods in vertical farms

Purslane (Portulaca oleracea) grows on the sidewalk already, and often next to some wild amaranth (Amarathus Hybridus). What is the point of more efficiently producing specific crops, when there are all these underutilized nutritious plants growing without any human input (or should I say growing despite human input)? This is another problem that I see with the technification of food production in general (including the Green Revolution). Some food wants to be free, but people keep looking for whatever makes the land produce more money in the short term, not what makes it produce more nutrition, etc., because the latter does not adapt so well to the market.
Security of your network shouldn’t depend on your visitors not running malware (and/or Windows). I’d suggest putting them in a separate WiFi network isolated from your internal LAN and from each other. Most decent APs support it and call it something like client isolation, on top of that you might want to assign this traffic to a separate VLAN that only routes to WAN.
Appears that a lot of third party apps are just using an older api that forces this notification to show. a lot less nefarious than it originally appears.

Seems that iOS14 offers a specific new API to check if there's something on the clipboard without actually seeing it which is what all these apps are trying to do.
Speaking of pseudoscience, didn't most police forces just start phasing out polygraphs in the last decade?

That's only the case if the credit card services are powered by a 3rd party.

Chase, Wells Fargo, USBank, BECU, Alliant CU, BBVA, Citi, M&T, and others are all instant if you're paying from an account at that bank.
I migrated our entire fleet to Fleetsmith a few weeks ago, largely due to their third-party catalog and features like Chrome extension deployment.

All third-party apps have now been pulled and we have virtually no fleet management.

Happy for them, but it's painful for us. Classic Apple move.
FIDO/WebAuthn has been designed to be first factor authentication (passwordless) as well as 2FA.

Though, I agree lost and stolen devices are a problem whose solution space needs more exploring than simply multiple auth devices.
"Surprise" is not a good standard for concern.
Didn't remember the name, but of course it's easy to find: Mark Russinovich. Now CTO of Azure. I'm sure he would not have envisioned Azure either when wrote the first sysinternals tools for Windows PCs...
Consider product management - a generalist, problem solving skillset is perfect, particularly at early stage startups. Being able to understand developers and communicate with them, even if you're not a good developer, is a really useful skill.

Shameless (but relevant) plug for a book I wrote about how to find/get your first PM job: https://www.amazon.com/Product-Management-Interview-Manager-....
Too bad this is just another low-code CRUD offering for SMB/Enterprise. This would have been so much more interesting if it allowed me to build an app for mobile and web with a custom domain, database modeling and storage, integration-eque triggers/automations, all while keeping the underlying platform invisible to the user. Instead, I have to create a team on AWS and then invite members who then have to install the Honeycode player on their phones just to use my app.

In other words, Bubble needs more competition.
What a neat idea, almost surprised I haven't seen something like it before.

I get that for print it's historically been best to just stick with black text on a white background, but for computer text I feel like this kind of technology should've been able to exist in the 90s.
Couldn't IOS just have a peek API that tells the application if the clipboard is empty or not without revealing it's contents?
Not entirely correct, Brave allows its own (and others') first party trackers. I'd suggest using ublock origin for greater control.

A lot of texas power grid is renewable however, which helps tilt the scales.
Air conditioning probably makes some people slightly fatter. There is a metabolic cost to regulating body temperature. As the temperature rises you actually burn more calories on thermoregulation.

Google acquired AppSheet earlier this year. AppSheet has been around for longer than Glide and it has more clients and features. They already acquired the leader in building apps from spreadsheets.
I agree. That pink is very hard to read. Might as well use yellow on white.
The total amount of electricity to power those UV lamps should be on par with what the Sun sends to the potatoes fields. Maybe that's the reason for fusion. It didn't do the math.
Depending on your climate and what you mean by "windows cracked", you would be much better off with a heat recovery ventilation (HRV) system. They have the explicit purpose of pulling in outside air while only losing about 20% of the heat difference between indoor and out.

With slightly open windows, you're losing a bunch of heat for very little ventilation.
p.s. One thing I can't figure out is if Honeycode can function as an API. If I am already using AWS for my other infra, keeping my data inside their "Excel" and then auto process and export it to somewhere using drag-and-drop automation, that makes perfect sense.

In fact, the whole "no code" Dreamweaver analogy isn't all that fitting. If they just said "Excel spreadsheet on steroids that integrates with other AWS product," would make more sense, to me at least.
They are the most expensive in the US system, possibly because they can be. US hospitals load costs artificially where they can (e.g. on the uninsured, because the insurance companies actually have bargaining power and wouldn't just pay any price).

Outside the US, many of these aren't the most expensive ones. Furthermore, "multiple surgeries" and "multiple specialist visits" might be caused by an emergency, but are very rarely scheduled as an emergency - the first one, maybe; the rest usually have 48 hours to 14 days in between (which often cannot be shortened for medical reasons even if you wanted). The patient might not be able to comparison shop between while recovering, but their spouse/kids/parents likely could. Also, many of those emergencies cause weeks or months of hospitalization - but often moving to another hospital is medically reasonable, and if it cuts the cost of care down 50%, many people will prefer it over e.g. bankruptcy.

The mere possibility that people will shop around tends to make a market much more fair.

And additionally, on average emergency care, even if more expensive, is small in the grand scheme of things. Continuous treatments and medications, and pre-planned procedures are the majority of the overall costs.
>> First, you have no time. You read a lot but there’s no time to think.

> This is has nothing to do with being a foreigner, or being in any specific country. It's a university culture, and every university has its own pace of teaching, in China or US.

It seems odd to assume that every University's pace is set independently of every other University. The vast majority of Universities and professors base their workload using other similar Universities as a reference. Either explicitly or implicitly. Some professors choose to make their courses more or less demanding, but even this is done as an adjustment from the reference point. Because of this, norms can vary significantly across different parts of the world.

I've never studied in China, so I can't say whether Chinese Universities really are less demanding. But after living and studying in multiple countries, I've certainly seen that norms do exist, and vary across different parts of the world.

> How hard it is to consciously decide to go to a book store when you are in need of a book?

That's the entire point. It's not hard at all when you consciously think about it and decide to do it. But most of our decisions and thoughts are driven by habits, not conscious thought. For example, it is extremely easy to not waste my time writing pointless comments on HN. And yet, here I am, because this is my habitual response to boredom.

Raku's big strengths lie, IMO, in the command line scripting capabilities (the MAIN function), parsing with grammars and powerful new regex syntax, and as a glue language. It's relatively easy to bind to external libraries and work with them.

Look at how easily raku binds to a python charting module in this article: https://www.perl.com/article/plotting-with-perl-6/
If I may ask, what was the use case for this code that they cared so much about a 2% difference in benchmarks? Aerospace? Game engine? Packet routing?
