NYC PHP Reboot - First up "Getting Specific About APIs" with Phil Sturgeon

engineering:

tl;dr Come and join us for the NYC PHP meetup @ Tumblr on March 1st 2018.
When
March 1st 2018, 7pm - 9pm
Where
35 East 21st Street (21st & Broadway), New York, 10010
Details
The monthly NYC PHP Meetup is getting rebooted in 2018! The first meetup will be hosted at Tumblr HQ in New York City, with Phil Sturgeon as headline speaker and two or three lightning talks.
About Phil Sturgeon
When he’s not talking about falling off bikes Phil Sturgeon is passionate about building great APIs. Sometimes scientists forget to label their units and they crash satellites into planets. Phil’s science teacher always told him to label his units and JSON Schema is how you do that in a HTTP API, even AMQP too! Come and learn about the future of APIs and other PHP topics.
We want you - for lightning talks
We are looking for 2-3 lightning (10-15 min) talks about anything PHP related. If you’re interested, please get in touch with Oli Griffiths via Meetup, or @oligriffiths on Twitter. This is a great way to get into the speaking community, and to test out material you might like to submit to conferences.

Announcing…

Three new features for posting from the mobile app

First, you can now add images to reblogs. You asked for it, you got it.

Second, new text styles for your text posts. Headers, lists, serifs, silly cursive, serious typewriter. Look:

Lastly, intriguingly, you can drag paragraphs and images around to reorder them. Handy.

Have fun with all this, Tumblr.

So pumped this has shipped. Proud of all of my colleagues who worked with me on this! Great work everyone.

Let hackday commence!

Trump’s Nutty “America First” Economics

Fri, 17 Feb 2017 14:47:35 -0500

robertreich:

Donald Trump gave a speech today at South Carolina’s Boeing facility where the new 787 “Dreamliner" was unveiled. He said it was “built right here” in South Carolina, and that “our goal as a nation must be to rely less on imports and more on products made here in the U.S.A.“

He also called for “a very substantial penalty to be paid when they fire their people and move to another country, make the product, and think that they are going to sell it back.” And said he’ll lower taxes and get rid of regulations that send our jobs to those other countries. "We want products made by our workers in our factories stamped by those four magnificent words, ‘Made in the U.S.A.’”

All fantasy.

In fact, almost a third of Boeing’s Dreamliner comes from abroad – from countries with high taxes and high regulations, good wages, strong unions, excellent schools including technical education, and universally-available health care.

1.The Italian firm Alenia Aeronautica makes the center fuselage.

2. French firm Messier-Dowty makes the aircraft’s landing-gear system.

3. German firm Diehl Luftfahrt Elektronik supplies the main cabin lighting.

4. Swedish firm Saab Aerostructures manufactures the access doors.

5. Japanese company Jamco makes parts for the lavatories, flight deck interiors and galleys.

6. French firm Thales makes its electrical power conversion system.

7. Thales selected GS Yuasa, a Japanese firm, in 2005 to supply it with the system’s lithium-ion batteries.

Oh, and the first delivery of the Dreamliner is scheduled to take place next year – to Singapore Airlines. Currently there are 149 orders for it from worldwide customers including British Airways and Air France.

In other words, contrary to Trump, the Boeing Dreamliner is made all over the world and will be sold all over the world.

Trump’s “America First” economics is pure demagoguery. We get a first-class workforce by investing in Americans’ education, training, infrastructure, and healthcare, and rewarding them with high union wages – not through xenophobic grandstanding.

My buddy got an Australian shepherd puppy. It’s ridiculously cute. However it’s not offered to throw a shrimp on the barbie or brought any tinnies so I can’t really tell if it’s Australian or not. 🤔

PHP 7 at Tumblr

Thu, 10 Nov 2016 11:11:37 -0500

engineering:

At Tumblr, we’re always looking for new ways to improve the performance of the site. This means things like adding caching to heavily used codepaths, testing out new CDN configurations, or upgrading underlying software.

Recently, in a cross-team effort, we upgraded our full web server fleet from PHP 5 to PHP 7. The whole upgrade was a fun project with some very cool results, so we wanted to share it with you.

Timeline

It all started as a hackday project in the fall of 2015. @oli and @trav got Tumblr running on one of the PHP 7 release candidates. At this point in time, quite a few PHP extensions did not have support for version 7 yet, but there were unofficial forks floating around with (very) experimental support. Nevertheless, it actually ran!

This spring, things were starting to get more stable and we decided it was time to start looking in to upgrading more closely. One of the first things we did was package the new version up so that installation would be easy and consistent. In parallel, we ported our in-house PHP extensions to the new version so everything would be ready and available from the get-go.

A small script was written that would upgrade (or downgrade) a developer’s server. Then, during the late spring and the summer, tests were run (more on this below), PHP package builds iterated on and performance measured and evaluated. As things stabilized we started roping in more developers to do their day-to-day work on PHP 7-enabled machines.

Finally, in the end of August we felt confident in our testing and rolled PHP 7 out to a small percentage of our production servers. Two weeks later, after incrementally ramping up, every server responding to user requests was updated!

Testing

When doing upgrades like this it’s of course very important to test everything to make sure that the code behaves in the same way, and we had a couple of approaches to this.

Phan. In this project, we used it to find code in our codebase that would be incompatible with PHP 7. It made it very easy to find the low-hanging fruit and fix those issues.

We also have a suite of unit and integration tests that helped a lot in identifying what wasn’t working the way it used to. And since normal development continued alongside this project, we needed to make sure no new code was added that wasn’t PHP 7-proof, so we set up our CI tasks to run all tests on both PHP 5 and PHP 7.

Results

So at the end of this rollout, what were the final results? Well, two things stand out as big improvements for us; performance and language features.

Performance

When we rolled PHP 7 out to the first batch of servers we obviously kept a very close eye at the various graphs we have to make sure things are running smoothly. As we mentioned above, we were looking for performance improvements, but the real-world result was striking. Almost immediately saw the latency drop by half, and the CPU load on the servers decrease at least 50%, often more. Not only were our servers serving pages twice as fast, they were doing it using half the amount of CPU resources.

These are graphs from one of the servers that handle our API. As you can see, the latency dropped to less than half, and the load average at peak is now lower than it’s previous lowest point!

Language features

PHP 7 also brings a lot of fun new features that can make the life of the developers at Tumblr a bit easier. Some highlights are:

Scalar type hints: PHP has historically been fairly poor for type safety, PHP 7 introduces scalar type hints which ensures values passed around conform to specific types (string, bool, int, float, etc).

Return type declarations: Now, with PHP 7, functions can have explicit return types that the language will enforce. This reduces the need for some boilerplate code and manually checking the return values from functions.

Anonymous classes: Much like anonymous functions (closures), anonymous classes are constructed at runtime and can simulate a class, conforming to interfaces and even extending other classes. These are great for utility objects like logging classes and useful in unit tests.

Various security & performance enhancements across the board.

Summary

PHP 7 is pretty rad!
