The Zen of Defriending

Seen on facebook:

Welp. There goes another Facebook friend, who decided facts about the southern border were inconvenient and did not fit her worldview, and decided that as a messenger I must be unfriended.

I’d like to remind people that “unfriending” simply means “retreat into my echo chamber”. If I was disrespectful, vitriolic, or hateful, then sure: unfriending would have a completely different meaning. But that isn’t the case. I don’t call people names. I try to respect others’ views. I don’t yell. I try to stay on-topic.

…

Unfriending is a retreat from thoughtful discussion. It isolates you from opinions that differ from your own. Stick to your views, respect your friends’ views, and talk to them. We need more talking

People should be free to friend or unfriend whoever they like. Freedom of Speech doesn’t mean I have to read your shit (or you, mine), and it certainly doesn’t apply to the failure pile in a sadness bowl substitute for real social interaction that is Facebook.

I never unfriended anyone on Facebook (or Twitter) until November 2016, but I never had a problem with anyone unfriending me, before or after.

Nor can I relate to those who do. Personally, it’s been quite a relief when I got defriended — my haters are pruning my social network for me! This way they can spout their shit freely without me. If, by some miracle, they have an original thought about a good programming design pattern, someone will eventually point me to it through a different avenue. I use Facebook for the baby pix and death notices and Twitter for the memes.

I suggest you feel the same/similar about being defriended, because being a butthurt snowflake when someone you don’t agree with unfriends you says more about you, then it does them.

If in our social networks we can unfriend others who are useless shits to us, if we can be happy when we are unfriended when we are useless shits to them, not only we, but everyone will profit from it. This is the most basic kind of social work.

You’re welcome. Just call me the Thich Nhat Hanh of your social network.

Vagrant, Time Machine, and waiting forever for a backup

For some reason, moving to the new MacBook Air hasn’t been very successful. My Alfred spotlight is broken, Apple Mail slows to a crawl for no good reason even though everything is in the cloud, and I have a \<50% success rate of backing up my Time Machine during my workday. Basically if it doesn’t complete before lunch, it isn’t going to finish at all.

That last one seems to be well within the realm of what’s feasible. I mean why is it backing up 15GB of new files each day and why is it when I really get working the last 2GB never seems to complete? Not to mention that this 5TB drive I purchased four years ago to back up what is only a 500GB SSD (was smaller in years back) is now starting to appear full.

Well I think I figured it out. I’ve been using Vagrant for the last 5 years to build out virtual machines for development and each of them is a single (very large) virtualbox file that needs to be re-imaged every time and is constantly changing if the machine is up during the backup process.

After some research here are some suggestions on what to exclude from your time machine backups…

Working scratch folders:

Things like ~/.Trash and ~/Library/Caches should automatically be excluded by Time Machine in general, but for me, I use ~/Downloads as scratch space for stuff that I don’t care if I lose. If it’s important, I usually drag that to desktop, so I added that. You can add something similar

Cloud files

I added ~/Dropbox because that stuff will be built from Dropbox, and Time Machine or migration restores will just confuse the backup system. If I used Google Drive, I’d probably add that too.

Virtual machines and other dev related environments

For me that’s ~/.vagrant.d and ~/VirtualBox VMs where vagrant downloads the boxes and where, by default, it puts the VirtualBox VMs. The actual boxes that I might image to do Windows/IE development are manually created and imaged in ~/Documents so there is no need to exclude those. If you want to keep your plugins then save ~/.vagrant.d/boxes only.

I also added ~/Library/Containers/com.docker.docker because sometimes I did Docker development and that’s where those instances are.

Also if you have a standard place where you put Python virtual environments with virtualenv you should probably add that too. I don’t develop on localhost anymore so that isn’t the case for me.

Local software caches

I added ~/.gem for Ruby and ~/.npm for NodeJS. I’d probably look into what I can torch from rbenv and rvm but I no longer do local Ruby development, but if you do, add those to your checklist.

Games

I don’t have this on my work computer, but on my home one, I added ~/Library/Application Support Steam/steamapps because those are big files that are downloaded from the internet anyway. When I get home, I’ll have to make sure that sort of thing wasn’t moved into /Users/Shared.

Unknown unknowns

I probably should figure out where Ulysses puts its files because every time I do Migration Assistant I have unresolved conflicts which take forever to clean up. It’s not a big deal though since almost all copies are actually the same file.

Know of any other things I need to add?

I’m speaking again!

If you haven’t been paying attention, I’m starting to speak again at PHP conferences. The first one is SunshinePHP in Florida. (I figured I needed to see the Sunshine State again before it all goes under water.)

My talk is going to be a case study on recommender systems. It’s a bit of an odd-ball because it’s not PHP-specific, but that’s because the company I worked at was a Ruby-on-Rails shop. It’s okay, it will still have application and ironically the heavy lifting is done in Python and Go. Lol! Trust me, it’ll be a good talk. Data is an important part of any website and this gets you going into how you can use it without all the bullshit “big data” buzzwords.

I really think you should register for the conference and come see the talk. If you are already going, please stop by and say “hi!” I promise, I won’t bite too much. I’ll be there for the entire event and this time I already have my talk 95% done so I won’t be holed up in the hotel room finishing slides. It’s been much too long since I’ve seen anyone in the community, and I’ve got to earn my place on the PHP terrorist deck.

See you in February!

Running Python scripts on a schedule in AWS

Answered in Quora:

Q: What is the easiest/fastest way to set up AWS to repeatedly run a small Python or PHP script (24×7)?

Probably the easiest way is to use Lambda. It has a built-in scheduler and you only pay for the time it is running. (Note that in PHP you have to create a lambda package using this tutorial or via node Serverless here.)

If you mean continuously, and not repeatedly, then the caveat for PHP at least, it is a bad idea to have it repeat forever in the process because it was designed to be set up and torn down and might leak memory (with the proper setting to set_time_limit and ignore_user_abort, have it run forever). In those cases you would have something else constantly call the php script via command line and restart.

Other than that, whether PHP or Python or whatever, it is better to create a non-burstable EC2 instance and run it, since it will always have some load. You can write something simple to the crontab that will make sure the process is always running or, better yet, use forever.

Old alumni page

One thing I’ll always be grateful to my father for was buying me a lifetime Caltech alumni membership on my graduation.

Dear Terry,

We are writing to share news about your Alumni Website. You may have received this email already, and if so, I apologize for the duplicate announcement.

First of all, wow, we were using a WordPress install for authentication for a CMS? Since when?

Second of all, I had a alumni page? Since when?

Hmm…

&lt;P&gt;I&#039;ll consolidate this sometime. It&#039;ll be so 3leet that it will be 4leet!
&lt;/BODY&gt;

Wow, that’s some old shit. I must have done that over 18 years ago. None of the links there even work. The days when we used to capitalize HTML tags, which is the reason why PHP functions are case insensitive by the way.

I never did get 4leet status by consolidating all my internet sites. They just all went down the memory hole. I think I’m going to let this one go that way also.

What’s something very few people know about PHP?

Answered in Quora:

Q: What’s something very few people know about PHP?

It is mind-bogglingly popular for web development. That popularity hasn’t diminished even though conventional wisdom says otherwise…

Over a decade ago, I said about 40% of the top 100 websites use PHP — a number I pulled out of my ass — but nobody (not even the Ruby on Rails developers I pissed off) argued with that spurious claim. In 2009, Matt Mullenweg, the creator of WordPress became curious with my claim and did a survey of Quantcast’s top 100 sites — he got almost exactly 40. Even today, among the 10 most important websites, four use PHP as their language of choice — 40% again.

Overall, almost 80% of the internet is powered by PHP, and that has held steady for years! Newer web languages such as Ruby or NodeJS have only grown at the expense of other languages such as ASP, Java, or Perl.

Just one single application written in PHP, WordPress, is used by over 30% of all websites on the entirety of the internet. That’s more than double the market share since back when I last worked at Automattic/WordPress in 2011! It grew until it saturated its entire market — over 60% of all CMSs. In the CMS market as a whole, PHP-based CMSs occupy positions 1, 2, 3, 6, 7, and 8 in the top 10. The most popular non-PHP-based CMS is both closed source and sitting at only a 2.5% share.

It was estimated back in 2009 that there were 5 million PHP developers worldwide. It’s difficult to make this estimate today, but it’s obvious that that number has also held steady or grown.

These last few years, I’ve been commercially working in Ruby (on Rails), GoLang, NodeJS (for static servers), and Python (Django), but PHP is still also my love in that love/hate relationship.

What don’t you like about PHP?

Answered in Quora:

Q: What don’t you like about PHP?

It’s a ball of nails with almost no logic to it. From the perspective of software language design — as Tim Bray, co-creator of XML and at the time Directory of Sun Microsystems’s Web Technologies division, once said — “PHP is soul destroying.”

To take one of the most notorious examples: strpos and in_array.

In one, the order of variables is $needle, $haystack in the other it is $haystack, $needle. I challenge even the best PHP developers to remember which it is without a reference. Also, even though they both serve the same purpose they return different things and don’t obey a consistent naming convention: they should be named strpos/arrayin, posinstr/inarray or `str_pos`/`array_in`. That’s three terrible design choices in one single example!

Another example is the namespace separator in PHP is what is an escape sequence everywhere else \\. Why? Because by the time PHP added namespaces, they had run out of ASCII symbols for the lexer.

I could go on and on, but I won’t.

I love the language sometimes because I hate it so much. 😉

After being constantly bothered by your automated help

Let’s just say when my phone buzzes at 10:30pm and again at 12am. I turn into Statler or Waldorf…

Dear DoorDash support,

I did not do this support request. I’ve never used your service. (I believe many at a previous company I worked at would use you when catered lunch wasn’t ordered that day, but I’m among those that subscribed to the theory of “Learned Laziness.”) In fact, initially I thought this was phishing or spam because we have no previous business relationship or customer interaction.

If the person who whined to you to create this support ticket provided a phone number or other contact information —which I’m sure they did if there was a real order attached — please contact them through that order and tell them to not mistype their email in the future. I can understand how not receiving their hot pockets or whatnot on time can be stressful (in my younger years I’d have probably blown up for less if ordering-shit-from-my-iPhone-because-I’m-too-lazy-to-walk-downstairs were a thing), but that’s no excuse for not double-checking what one is typing in the contact field(s).

If I keep receiving these e-mails , I’ll simply train my mail filters to ignore and and all future e-mails coming from you.

I wish you all the best! Thank you.

terry

P.S. There is an apostrophe in “youve.” I normally wouldn’t mention it, but it’s in e-mail template you have probably sent out more than 10 million times and I’d have think it’d be a little embarrassing that the $970 million in venture capital you took in didn’t pay for a spell-checker.

Back Kill Merlin!

My former CTO started to develop a board game with his kids back when I started working there. He just posted it on Kickstarter and you need to back it right now!

It’s pretty amazing seeing it evolve from just a bunch of handwritten cards and a board to what it is today.

But if you don’t believe my review, you can always check out independent reviews on BoardGameGeek.

It was a struggle balancing this game with his wonderful family and a startup to boot. I remember discussing with him the struggles of whether to go to GenCon and still making his kids’ events.

Personally, I wish the title of the game was someone else than Merlin , but other than that, I’d have given the game more thumbs up if I could.

And, Dave, if you are reading this. Yes, I was backer 139. I would have been a lower number but… well you know what’s happening on my end 😉
