Are you sure COVID-19 didn't partially prick a systemic issue that was hard to see on the rise (as many also missed the housing crisis before the fall)? For example, the amount the stock rise was attributed to stock buybacks in an unsustainable manner caused by late stage government policies (tax cuts, low rates). There has been some pretty extreme levels of corporate debt that correlates with this.
Are you sure it wasn't Google's AI that wrote it?
Although the OP didn't describe as such, but health checks that do a simple query are also testing the connectivity to the db. Someone might have hardcoded a db address in an environment variable, or there are connection pooling issues.
Promises made some very valuable improvements to code patterns relative to callback-based implementations, but as a broader "nodejs vs synchronous style code" its still much harder. You sound pretty versed, but other folks might struggle. Here is an example explanation:

If we're trying to show the simplicity of modern nodejs code with non-blocking I/O, I would suggest we lead with examples like:
const foo = await queryFooObject(id); await writeToFile(foo);
True, there's still plenty of value in promises, especially for things like:
await Promise.all(severalParallelQueries);
Tableau did some research in this area, and found NLP queries were much faster:
We don't use postgres pub/sub for exactly "realtime", but do make use of it in single-page apps that use websockets. A couple notes:
-- LISTEN/NOTIFY has a payload size hardcoded maximum. For big documents, we have to send a record ID then fetch the document upon receiving a message. In practice, it adds 5ms of overhead.
-- One of the best features is that you can combine this with pg_try_advisory_lock to create job queues that use the core locking features of postgres, which are pretty darn reliable and well defined. We use nodejs, and if the server processing a job dies, the lock is released automatically and another nodejs process can pick it up.
Hey I thought I'd reply here on the topic of the blog's usability to not hijack the whole thread....but I still wanted to help the author out with a quick fix:
This text's link doesn't work:
(see http://www.whitedb.org).
"Well, Java isn't verbose."
Maybe its just the code I've read, but its generally much longer than other languages to accomplish the same thing. A bunch of little things add up, such as "extends" instead of ":" for inheritance. Naming things is often longer - maybe its not the language core itself, but a counter example is python coding standards keeps them much shorter. With Go, there's duck typing to not have to declare obvious types (such as for strings).
The goals of the programs in enterprise java apps probably differ by an emphasis on readability and not writing speed. I.e. lambdas are written quicker to write, but maybe a reader would understand a strategy pattern's goal quicker.
Often, the most economical answer is heating a water heater rather than storing via a battery.
Maybe panel prices have dropped enough in the last 4 years that partially-lit areas are now worth covering in solar (cost < savings * acceptable ROI months).

I think NPM 3 is adding flattening. I.e. if A and B both are alright with 1.0.2 of C, then it'll not duplicate it under A and B.
I think the author is referring to using Swift instead of phonegap/cordova/transpilers, since performance will be improved and you're not limited to just javascript as the originating language.
"Red Hat have OpenShift and are making noises about turning it into a Docker+Kubernetes thing in version 3"
They've already decided that, and have even reached code-freeze. Their conference is later this month, so that's when it's going to all be announced and rollout plans detailed.

Our city (Raleigh) had the last B&B close, and the owners blamed it on Airbnb:

" never said popularity was an argument for quality. You did."
I'd tend to think your statement:
"And if MySQL wasn't robust then YouTube, Facebook, Twitter, Alibaba, LinkedIn etc wouldn't be using it for core parts of their infrastructure. It's definitely robust."
..points out that many (popular) sites use it, and a prerequisite is robustness, which thesaurus-wise, sounds a lot like quality.
I get that
a) you didn't actually say it, and
b) you could mean something much more specific, such as "companies with many highly-starred, complex open source projects which have also re-written major parts of their tech stack, but chose to leave mysql in place".
I know thats a bit more verbose, but it just seems to obviously close to the other author's interpretation with the ambiguity of the statement.
"This raises an important question, which is, who was using that wheat that the FDA considers unfit for human consumption? I worry that my dog is eating a lot of vomitoxin."
From Wikipedia:
Vomitoxin is not a known carcinogen as with aflatoxin. Large amounts of grain with vomitoxin would have to be consumed to pose a health risk to humans.
Companion animals: Dogs and cats are restricted to 5 ppm and of grains and grain byproducts and the grains are not to exceed 40% percent of the diet.
A second typo:
"This tools hepls"
Hey curious about downvote (honestly, want to know why). I didn't see anything saying that was a bad idea in the HN guidelines:
https://news.ycombinator.com/newsguidelines.html
I felt the typo was one where I had to do a double-take and make sure it wasn't some purposeful acronym. So, I posted a quick note since it looked like the HN poster also was the article writer, and my comment would drift to the bottom quickly and wouldn't get too far in the way of a larger discussion.
I could see maybe I should have made my comment more verbose so someone wouldn't interpret it as being short or something? Or is there an unwritten rule about not making quick editorial comments?
"Your Product Owner is more like a Shadow Product Onwer"
Typo with 'Onwer'?
Have you thought about JSON as a partial query placeholder, and all the native methods available for traversal, merging, plucking, etc.?
For example, here is :
{ type: 'select', columns: [{ expression: 'orgJobs.org_job_code', alias: 'job_code' }], joins: [{ table: 'org_jobs', alias: 'orgJobs' }], limit: 100, offset: 0 }
which yields:
select orgJobs.org_job_code as job_code from org_jobs as orgJobs limit 100 offset 0
and so its easy to do things like:
query.limit = 100;
and of course:
query.columns.push(additionalColumn);
and use something like lodash/underscore (or equivalent for your language) to add collection/array/object helper methods so you never have to write for-loops for things like mapping and property plucking.
"You still need to supply the local variables to your ORM"
That can be done automatically in many languages. At least in the sense you can do:
"where value=$(bar)"
and not:
"where value = ?", bar
OpenACS was an old web framework for the Tcl language, but it even had that 20 years ago!. The company backing it failed in the .com era, and the lack of types was a turnoff for many - but it made SQL much much more readable. And of course the queries were turned into prepared statements. A query looked like this:
select foo from table where age>:min_age and name != :user_name
Things like this can also be done in node.js (disclaimer: I wrote the blog post below):
No Soup for You!
Yes, that would be interesting data. Most companies would output reports from their HRIS systems in wildly different formats, and you'd have to adjust for industry, geo/currency, year, gender/ethnicity/language, and all sorts of things. But just getting that data and the sensitivity that goes with it would be near-impossible unless you were a salary survey company. And then, they get job-level data and not per employee. They charge serious money for the services of analyzing this data and do not make their data available.
Hey just curious, why did you pick spacemonkeygo/monitor over mozilla-services/heka for data collection?
I was thinking of using heka for a logstash-like project and just wanted to see if you had found several know issues, or that monitor really shined, or that maybe the feature set you needed just didn't overlap to the point they were comparable for your needs?
You can actually load libraries in plv8. Its cumbersome, and not a simple:
var _ = require('lodash');
but it works. Part of the reason is plv8 is a trusted language, meaning it cannot read code from the file system. Basically, the libraries are loaded as text into a table, and then evaluated by v8 using the library loader. Someone could make a gulp task to make that a quick command line tool if they did it often enough....
Followup on this. To avoid the in/not-in <array> expansion, the trick is actually to use:
foo=any($1)
where $1 is an array instead of in ($1, $2, etc.). != any($1) is the same as 'not in'.
RE: expand array for in-clause, its definitely not supported automatically by node-postgres:
http://stackoverflow.com/questions/10720420/node-postgres-ho... https://github.com/brianc/node-postgres/issues/431
which I confirmed:
promise catch err: { [error: invalid input syntax for integer: "{"45","56","33"}"]
but I can make this work by altering my 'sql' tagged template string function, and inspect for typeof <var> array and automatically expand. I wonder if there are there other purposes for arrays other than the in-clause syntax that I should check for.
