Good question! Sorry to be kind of cryptic there in the interest of brevity.

Lodash is sort of a query language for data in JavaScript. The name is a play on Underscore, the name of a rival implementation. So Lodash is literally a "lowered dash character"... i.e., an underscore.

Anyway, here's an example in the code for the website I mentioned above[1].

In this example, Lodash is wrapping a JavaScript array of objects named "rows", filtering out just the "keys" in the objects, further filtering down to only the ones that are numeric, and then mapping those to an array of strings that are properly-formatted dates.

The original array came from Hugo-generated JSON exposed as a read-only REST API[2]

You don't need a single tree across the entire timespan you want to look at. You can assemble a series of overlapping samples from a number of trees that lived at different times during the timespan of interest.

From Wikipedia [1]:

> A fully anchored and cross-matched chronology for oak and pine in central Europe extends back 12,460 years, and an oak chronology goes back 7,429 years in Ireland and 6,939 years in England. Comparison of radiocarbon and dendrochronological ages supports the consistency of these two independent dendrochronological sequences. Another fully anchored chronology that extends back 8500 years exists for the bristlecone pine in the Southwest US (White Mountains of California).

> I'm not sure I can answer this, but it might help anyone who could if you know an example of an application that does the nature of tracking you are concerned with?

Using any map application (especially google maps) does not actually need to store my location for posterity to give me useful service, and I did not opt-in but android still does; Perhaps it's because I haven't been back inside Europe in the last month or so (and when I do, I'll get a "please opt in" prompt).
I went this way too. If your site has a dynamic/interactive frontend, Gatsby makes it super easy to build a static-but-interactive site. Another huge plus with Gatsby is that it uses React's server-side-rendering to ensure that the site is still seo-friendly.

If you have more than a few snippets of JS on your site, Hugo comes up way short. It's great for simple things though.
Meijers is really the HEB of that area. I couldn't imagine living out there long term as a non-religious, non-straight person.
Interestingly, The NY Times is also extremely influential in US politics, so it does seem that reducing Facebook’s influence has a benefit to The NY Times. Anyone have any data on the tracking that The NY Times website uses? Just curious if there is any hypocrisy or conflicts of interest. Most news orgs seem to aggressively track.
While the oldest living trees are there, its not living trees that are being dated. If you find a timber used in the construction of the pyramid, you can then match its tree rings up with another set of tree rings that overlap, and so on back to the present age. In theory.

See https://www.crowcanyon.org/index.php/dendrochronology

The challenge is there are gaps and spots where it doesn't quite match up. A bad few years and it throws the tree rings off. However, if you can pinpoint some reference event that spans the globe, you can line the samples back up again. This is known as cross dating ( http://www.ltrr.arizona.edu/lorim/basic.html ) - it doesn't need to have a living tree.

Radiocarbon dating will never be precise (being able to pin down a specific year) because of the probabilistic nature of decay and the errors on that are on the sample. Carbon dating only gives a one sigma. Something that is 3500 BP (before present) can have a +/- 60 year error on it. Give https://en.wikipedia.org/wiki/Calculation_of_radiocarbon_dat... a read.
Not sure what that has to do with anything, I was posing a question.

Rebellion against the status quo has an equally rich academic tradition. "Education" in the abstract doesn't prefer one view over the other.

Further education is in no way a guaranteed path to success: I have two BS degrees Physics and Geology with math and CS minors, and yet I am a stock boy at Target.

Nothing is a path to anything. We of course hear from the successful children of "tiger moms" but how many stories in the last 50 years do you remember with the headline "my mother demanded everything and I am a fork lift operator at an industrial door warehouse" and yet https://m.huffpost.com/us/entry/us_58ff7f40e4b0c46f0782a5b6 Asian Americans are statistically poorer than most...
It's not quite that simple. I have three kids who were all raised with the same emphasis on the importance of education. They all have different levels of motivation at school, different interests, different passions. Most of the people I know with more than one kid say the same thing. Same with my brother and me. We were both raised by the same parents, in the same house, yet he was much more motivated to go farther with formal education than I was.

Patents are strictly an offensive measure: They only allow you to sue/stop someone else from using them. They do NOT give you approval to do something.

Some people mention "defensive" patents; They are only defensive in the sense that "the best defence is an offence" - that if someone attacks you, you have something to attack them back with. But that's not actually useful against entities that aren't practicing, such as Intellectual Ventures.
How eBay shaped the modern internet
> Once you get above about 256 GB of RAM

I think it might be as high as 1TB these days, though with what's going on with DDR4 prices, the situation is strange at the moment.

Of course, I don't disput your point that a 100+TB database isn't all that large, especially with indexes.

I suspect that it's this false dichotomy of "fit in RAM" and "big data" has resulted in many needless forays into distributed computing.

I'm no expert, but Cats and Squirrels would be pretty good at hearing and seeing danger, even feeling vibrations nearby. I doubt they'd get caught by a lawn mower at walking speed.
From my experience, Tiger Parenting is a very effective way of propelling people through standardized testing and competitive exams/admissions. I think it tends to stop working once there is not a clearly delineated pathway to achievement - for example in independent research.

It's absurd to think that no-one who came up with a Tiger Parent philosophy won't be a good researcher or independently creative, but there does seem to be a rapid winnowing of people who were previously overperforming on tests and 'routine intellectual work'.

> Rebellion against the status quo has an equally rich academic tradition. "Education" in the abstract doesn't prefer one view over the other.

Before you can rebel academically, a decade of conformism is required. So few nonconformists survive that such traits are immediately valuable - but do not mistake that for neutrality, modern education is conformist above all else.

> Further education is in no way a guaranteed path to success.

Sure, and I made no such claim, the article author is concerned about educational achievement in and of itself.
No we have to filter people because if we did not there would be chaos, and everything that makes America a great place to live would disappear.

Not necessarily. Currently a topic is simply the keyword when you do search on HN powered by Algolia.
What do you mean when you say 'database migration'?

In my mind, there could be a few things:

1) Migrating the database from server A to server B where the server is on Kubernetes

A1) Don't do this. Don't run a (traditional) database server in Kubernetes. Sure, you can do this - there are all kinds of volume support for all kinds of things. Everything I've ever heard and read has told me that containers aren't a good for for this type of long-term service that gets refreshed infrequently.

2) Migrating the database from server A to server B where you have to tell all of the clients what the database is

A2) This should probably be done via service discovery or even just by a short TTL on a CNAME in DNS.

3) Something else?
The fact the UMich is one of the top schools in the country definitely helps.

TLDR: very few stocks have outsized returns over a relatively short period of time (usually early in the life of the companies). Most stocks (>50%) in the S&P500 (which suggests the DOW would be worse) are just outright bad investments.
>Asian Americans are statistically poorer than most...

Not only is that untrue, it's the exact opposite of the truth.

No, Hebrews 11 only provides an interpretation for what happened in Genesis 22. Coincidentally, it's also the interpretation that's the most logical in light of the context; one can come to a similar conclusion without ever reading Hebrews 11. The context is provided by Genesis chapters 15 to 24, as well as all criticism on child sacrifice for the purpose of worship in Leviticus, Deuteronomy, Isaiah, Jeremiah, Ezekiel, etc. Now infanticide does happen in the Bible, and some of it is condoned by God, while some of it isn't. The times it is condoned by God, there are interesting situations and reasonable explanations. The times it isn't condoned by God, there is consistent logic as to why it was OK one time but not OK another time.

Now of course, all of this understanding by people of faith could be completely wrong. But there is often difficulty having dialogue on the matter because when skeptics criticize what they find to be odd behaviour or odd contradictions in the Bible, they often lack comprehensive knowledge of the Bible needed to come to logically valid conclusions (note I said logically valid, not logically sound). Bertrand Russell did it when he criticized Jesus for making the fig tree wither, he didn't understand what was happening there. He lacked Biblical context of certain passages about fig trees in the Old Testament, and he also lacked botanical context of how fig trees grew in Palestine.

When people make conclusions without getting the full picture, it is natural to come to strange conclusions. This applies to any area or body of knowledge and analysis from the study of physics to language acquisition. We wouldn't say that Bilbo was an evil character because his true colours were revealed when he saw the One Ring in Frodo's possession in Fellowship of the Ring. No, we'd understand what Bilbo went through with the ring and what kind of person he really is because we read The Hobbit first. And there are aspects of the One Ring and The Hobbit that we cannot fully understand without reading The Silmarillion first.

I believe I shouldn't try to have these types of discussions on HN. Sorry if it is too much. If you're interested in taking this discussion offline to really dig into it, let me know. :)
Payroll companies (ADP etc)

Background check companies that do employment reference verification checks for employers

All three credit reporting companies have employment history products. So for example if your rental application includes your current and/or past employers, those will end up permanently with the credit reporting agency.

Plus others. Basically anyone that gets your employment info will sell it since as far as I'm aware it is not protected in the same way your credit history is.
Ask HN: Version control for hundreds of Wordpress sites
Howdy!

I'm in way over my head on this project!

I've got ~500 Wordpress sites I'm managing and I need a reliable way to backup sites. This would be for both security and development purposes.

I know there's a lot of redundant files across sites, so I think I should approach it in two ways. I should have a system to backup the MySQL databases and then another way to backup critical files from /wp-content and other folders.

As I mentioned before, I'm in way over my head with this! I'd greatly appreciate any tips or advice.

Cheers!

To play devil's advocate, there are not enough raw materials on earth to produce close to the amount of necessary devices that would fill the ipv6 space.
I can be convinced that this large amount has other benefits, but not that this number of IPs was needed for futureproofing.

Ask HN: How good are the “MasterClass” online classes?
To be clear, I'm referring to https://www.masterclass.com/.
I'm not really a professional in any of the fields they offer classes in, and am looking to take it out of curiosity, to get a sense of the different industries (like space exploration, investigative journalism etc). For those who have taken classes, how has your experience been? Is it worth the money and time? Do they come off more as a documentary (I felt the trailers do) or are there clear, useful takeaways?
Anthony Pompliano's Daily Crypto Newsletter
Hehe. Apparently, for Ender's Game, there were actors who actually refused to read the book because they feared it would affect their work.
OLPC did for Netbooks what Raspberry Pi did for Single Board Computers, essentially creating a new & much larger market for devices that existed, but had been priced much higher before either of those entrants had entered the market.

I don't think this upstart will see much success though, as the price point is out of reach for most locals. Refurbishing laptops en masse for less than half the cost would likely get more powerful hardware into the hands of notably more people as compared to buying new hardware from an ODM.
That inconsistency is that users are generally on much less trustworthy networks and DNS right now is rarely authenticated (DNSSEC is not wide spread and even then most clients don’t authenticate it)

While not perfect it’s generally quite true for the majority case.
>“Perhaps Facebook should consider not aggressively getting more people online through its free internet program, and on its platform, until it has fully realized the scope of various ways it impacts a society, and often the whole nation,”

Imagine the amount of first world privilege you need to have to be able to say this with a straight face. While we're at it how about we don't spread education and vaccinations across developing countries as well, until we "fully realized the scope of various ways it impacts a society, and often the whole nation".
It seems to be a bit of a disservice to be running such a flashy GTK 3+ desktop. I would have picked a stock Lubuntu with just a branded desktop wallpaper/theme. Haven't personally used Budgie Desktop so maybe it's fine. Anyone have experience with it?

Of course I'm not in sales or marketing so the appearance of the latest Mac (even if on insufficient hardware) may sell well and work well enough for casual users. Actual developers should quickly find ways to make it more usable.
Ask HN: Simpler alternatives to LaTeX for note system
Wondering if others could share some ideas about typing up notes - workflow, software, typesetting system wise? Preferably options that will output to PDF and are command-line oriented.

Currently have some notes in mostly plaintext with some LaTeX markup in it. It renders fine, but its difficult to maintain.

I'd like to try out a different workflow software / typesetting wise. ConTexT seems to be a viable option. The sytax is an improvement for me anyways.

I've looked into lightweight markup but some don't seem very flexible or have long dependencies. Org-Mode might be a good choice but I'm mostly used to working with Vim.

Wiki and Note-taking systems (notebooks) systems don't appeal to me much, though I've seen they are popular.

There are several on-going or deprecated projects that are of interest, mostly 'Tex engine replacements. (I've spent more than a few hours searching through many linked on Wikipedia like here https://en.wikipedia.org/wiki/Typesetting and some more obscure ones. I like some of the Scheme and OCAML projects, but all seem to be difficult to compile on several systems I tried.

So, other than ConTeXt, I'm considering Org-Mode.

Is there another option being overlooked?
With how low the average salaries are in Cambodia, it is financially out of reach for most of the population.
As a counterpoint, I would like to say that a lot of research still is 'routine intellectual work'. Movers and shakers are rare and far apart. The vast majority of academia are collectively and slowly boiling over problems, rather than taking bold and independent strives.
I try to wire my brain to do routine tasks without having to give many thoughts. Besides the usuals where electronics, gadgets, and computers are involved, I'm more interested in the ones that I cannot use machines but my own body and brain. My wife believes that I know almost everything where they are and will likely be -- I just define a pattern based system of keeping things -- think massive CSS with Classes/IDs all over and how I could quickly navigate without much effort (before Google Chrome Dev Tools and all the niceties we have these days).

Here is an example. Every morning, I have a routine where I prepare my daughter for school. I don't even have to prepare the night before.

I wake up at 6:00 AM by a soft alarm. I'm kinda beginning to wake up on my own more often these days. I go to my daughter and try to wake her up but I also know she would reply, "Give me few more minutes, please." "Ok, 5 minutes." I then line-up her school uniform by the edge of the bed -- shirt and skirt at the bottom, then the underwears on top.

I flip the light switches on from the hallway all the way down to the kitchen liting them up to make it full daylight when she wakes up. I quickly check her school bag, fill-up the water bottle, and line-up all the tiffin materials at the kitchen counter. Then pour out the milk/juice with egg/bread for her and keep it ready. When all that is done, I put the socks that I picked up while preparing her uniform, in her shoes and is kept ready by the door.

I start the tea going. To the Bathroom, brush my teeth, wash-up, dried up. Then, I go wake up my wife, "Tiffin ready to be prepared." I go to my daughter, "Times up, very late." I lift her up and show her to the bathroom door. She would have slept for about 15min instead of the 5 but that is what I intended.

Wife goes to the kitchen and cooks, prepares the tiffin, packed it and keep it in the kitchen counter. She then prepares the milk formula for our younger daughter, give it to her (she holds it in her sleep and drinks). Wife goes back to bed. I go in and finish the tea which the wife had adjusted for it not to spill over.

Daughter comes out of the bathroom, get dressed, comes out of the room and drinks/eats her breakfast. During this time, I'm in my study room, logged into the computers, get the emails flowing in for me to look later. I finish my first tea of the day.

Escort daughter to her school bus.

This is one routine that has worked really well for the family with little to no adjustment or breaks. That one hour from 6 to 7 AM in the morning all goes without much thought but more from my muscle memory, following patterns of where things are kept and where to keep them.

I hope I can call this automation.

Tracking Progress in Natural Language Processing

Totally unsupported by examples, but it seems like the huge economic benefits will cause society to underestimate to risk of autonomous vehicles. We'll debate and distort the relative risk and provide plausible deniability for the right people. In the end, we'll tweak the AI based on real world failures until it's good enough to win the PR battle. This is assuming it can be tweaked to work. The key will be protecting (or limiting) the liability of car manufactures from lawsuits. If AVs are involved in 37,000 fatalities a year (the 2016 human stats) the lawsuits will be untenable. Maybe there's a plan to handle this, and I just haven't seen it. Just my opinion...
Products like these will change the future of how learning and new skills will come out of Cambodia.

I just returned from Cambodia last week. I have been around the provinces with my Cambodian friend. What I came to know is many young people who are also smartphone users are not able to read or write Khmer, let alone English. The smartphone usage is mainly around using facebook, mostly to post pictures and watch videos. Though the internet infrastructure is good in Cambodia, it's underutilized.

What I wish to see is how localization and learning software powered by TTS/AI along with inexpensive hardware would inspire them to learn and acquire global outlook.
They could support tracks on existing vehicles by making new hubs/shafts. You remove the hub, add a shaft extension, replace the hub, then get spare rims and tracks out of the boot and do an Indy 500-style fast wheel change. If you hustled my bet is you could do this in 2 minutes with four people. Would add significant unsprung weight but would support existing vehicles.

If you modify the vehicle you can support this without changing the hub and shaft/extension, just change the wheels and add tracks. But I'm assuming they wanted to work with a mostly stock vehicle.
So, the way I think this should work is that there should be a way of addressing the table sources in a query from an application that has them parsed, and then externally (i.e., in the application) provide planning hints to the compiler.

Something like (in some terrible pseudocode):

q = parse_query("...");
q.hint(FIRST_TABLE, "a");
q.hint(INDEX, "b", "b_idx1");
c = q.compile();
r = c.run(...);
