halis··on Anyone made the jump from MySQL to PostreSQL? It is worth it?
Migrating from Oracle to Postgres is much more appealing because you can avoid the high Oracle license costs.

I don't really see that much benefit in converting from MySQL to Postgres.

While Postgres is a legit database, so is MySQL. If you're looking to scale MySQL, I recommend the book High Performance MySQL.

For greenfield projects I'd be comfortable with either MySQL or Postgres.

halis··on Adobe Warns Customers of Potential Legal Action for Using Older App Versions
Don't negotiate with terrorists. Just cancel and refuse to do business with Adobe for the rest of your life.
halis··on To ORM or Not to ORM
I was pretty excited when I originally learned about ORMs. But I quickly found that their usefulness is very limited in the enterprise, where most of my career has been spent.

You will likely find, as I did, that enterprises literally have thousands of databases of all kinds and many crazy data models.

They have tomes of huge SQL procedures that are still to this day running their business processes. Maybe even a nice older gent that is the only one that really understands how any of that shit works?

If this sounds familiar to you, then don't waste too much time on ORMs. In my experience, they're only good for mapping out your POJO or POCO objects and performing simple CRUD operations.

Use them to stand up simple REST routes that do CRUD on your entities. That can be the API that you use to do development and testing, and possibly even use those CRUD routes to do larger business operations.

But in reality, the business "requirement" is going to come down to you, the developer, in the form of some old terrible blob of shit SQL. Two thousand lines. Ten thousand lines.

You're probably not going to bother deciphering all that and re-writing it. The ORM is going to barf all over itself if you even try to use its API to execute that query. Even if you could express all those joins and case statements via the ORM, it is going to pick an execution plan where the query finishes sometime after the next Hanukkah.

At this point, don't bother with the ORM. Drop down to some driver where you can just run raw SQL and run the raw SQL.

Create a REST route that just calls this whack query directly.

This all may sound cynical and it is. But I know what I'm talking about. Do yourself a favor and remember what I said.

halis··on Base salaries offered to software engineers in SF, NYC, and Seattle
That's sad. For the senior levels, you can almost make that much in St. Louis.
halis··on Ask HN: If my company bills me out at $165/hr what should my salary be?
Don’t agree to a salary. Get them to give you a 1099 and pay you an hourly rate.

Pay your own quarterly and payroll taxes and write off your expenses. Get your own health insurance.

You’ll come out like a bandit. Since they aren’t paying payroll taxes or giving you any benefits, the spread they keep is pure profit.

So why wouldn’t they agree to $140 an hour? Why indeed..

halis··on Microsoft Edge and open source collaboration
This announcement is about 6 years late, but yeah, it makes sense!

Now, there may be some point in the future where I open a Microsoft browser and do more than barf on myself and download Chrome.

halis··on Ask HN: What are your “brain hacks” that help you manage everyday situations?
Do what's right for the company, not what's right for you. It will make it easier to win people over to your side and combat those who are only thinking about their own politics.

If a user tells you the data is wrong then follow the data. Trust but verify. The data may lead you to other data and the solution.

If there's no indicator of bad data then follow the code. There's always a reason. You'll be amazed at what you find.

Presidents can tweet about grabbing pussies.
halis··on Ask HN: How do you feel about backchannel communications for engineering teams?
I think it's fine to have a private channel for developers. If nothing else, it will give you a place to discuss technical problems without all the other noise.
halis··on Ask HN: What can be done to prevent a climate catastrophe?
I feel that unless we make some major breakthroughs in atmospheric carbon capture in the next 30 years, we are going to be royally screwed.
halis··on Boeing may have used a lobbying firm to plant a scathing story about SpaceX
Some companies don't rely on intelligence and innovation. They are one of a small group of big players and their business model dictates that they have to block any competitors from attaining success.
halis··on Ask HN: Was hired to improve company's devops, founder won't listen to my ideas
Maybe he just doesn't like what you're selling. Find out what direction the company wants to go and help them get closer to that.

I would recommend temporary feature branches, that frequently merge into master and also release branches for the code that you want to push to production. You can always do hotfix branches off of the release branch.

There's always that wet dream of no branches at all, every edge case automatically tested and pushing right to production if the tests pass. But this is really not practical for most places of business.

But if you can promote some meaningful amount of: 1) Unit tests 2) Integration tests 3) Functional tests That automatically run when code is pushed, that's a good first step.

Also, if you can get them on a regular release cadence of monthly or better, that would also be preferable, and you should be able to release code to pretty much any environment with the click of a button and with little to no manual intervention.

Oh and use Vault. :)

Stick with the basics and it will take them a long way.

halis··on How true hackers write JavaScript

  My opinion of the code is this. 
  It's pretty tight, which I can respect. 
  I haven't run it, but it PROBABLY works.

  But it's hard to read. 
  Things are named poorly. 
  Many edge cases are missed (not checking args properly).

  These functions are not pure and therefore, harder to test. 
  Maybe true 1337 H@X0Rz don't need to write tests, but some of us have mortgages to pay...

  I didn't re-write all of this mess, but check out the few util functions that I re-wrote.

  As a developer, which version would you rather work with?
  If you said the original version that's cool with me.
  But don't try to come work on my team.

halis··on Engineering whiteboard interviews: yay or nay?
If you're going to interview someone that is going to write code that a computer runs, then make them write code and run it on a computer IN THE FUCKING INTERVIEW.

Silicon Valley is retarded.

This book is very good. If you like Javascript and want to further your understanding of functional programming, then I would highly recommend it.
halis··on Ask HN: Are there any reasonable alternatives to MacBook Pro for developer?
In my opinion, the answer to this question is no. But that's the thing, that's the answer for me. For you who knows!
halis··on Why Can't Hollywood Make a Good Video Game Movie?
I'm a huge RPG fan, so don't get me wrong, I love video games...but let's be honest, the stories only go skin deep. They are mostly shallow and the characters are mostly stereotypes that belong in a D-list movie at best (think Billy Baldwin).

My opinion is stop making super hero movies and video game movies. They may be somewhat fun, but they provide no sustenance, it's like eating Ramen.

Make some movies from the DragonLance books. There are some fantasy stereotypes in there, but the stories are awesome overall.

halis··on Ask HN: Is Vagrant dead or dated? Do people still use it?
In order of complexity you have: * shell scripts * AMIs * vagrant * docker

Depending on what you need, any one of those may be a valid option for standing up a box.

I could use a shell script to essentially do everything to prepare a box.

If it's a stateless server, then creating an AMI is simple and the image can be used to drive auto-scaling groups etc.

If my local development scenario is more complicated or I'm doing it a lot, maybe vagrant is the better choice. Because then it can setup the box as well as provision a vm with virtualbox.

But if you're doing something in the cloud or something beyond an auto-scaling group, I would look to docker for inspiration.

That's where I'm at.

halis··on After 3 Months of JavaScript Linting, It's Pretty Much All Pain and No Gain
We're using prettier on a project at work. I was reluctant, I thought that there would be lots of bugs and mangled code, but it has been wonderful.

We run eslint with the fix option and prettier all in one command. It even formats JSON that you paste in for a test and changes the quotes to your preferred quote.

A+

halis··on ‘This’ in JavaScript
`this` in Javascript is an anti-pattern and so is this article...

I wish classes didn't make into ES6, object-oriented programming is a waste of time.
