Live Preview: Build and Test Workers Faster with Wrangler CLI 1.2.0

As part of my internship on the Workers Developer Experience team, I set out to polish the Wrangler CLI for Cloudflare Workers. If you're not familiar with Workers, the premise is quite simple: Write a bit of Javascript that takes in an HTTP request, does some processing, and spits out a response. The magic lies in where your Workers scripts run: on Cloudflare's edge network, which spans 193 cities in more than 90 countries. Workers can be used for nearly anything from configuring Cloudflare caching behavior to building entire serverless web applications. And, you don't have to worry about operations at all.

I was excited to focus on Wrangler, because Wrangler aims to make developing and publishing Workers projects a pleasant experience for everyone, whether you're a solo dev working on the next big thing, or an engineer at a Fortune 100 enterprise. The whole point of serverless is about reducing friction, and Wrangler reflects that ethos.

However, when I started at Cloudflare in early June, some parts of the development experience still needed some love. While working on a new WASM tutorial for the Workers documentation, I noticed a storm brewing in my browser…

Wrangler lets you test your Continue reading

The Week in Internet News: White House Proposes Social Media Monitoring

We’re watching you: A leaked proposal from U.S. President Donald Trump’s administration would put the Federal Communications Commission in charge of regulating how social media platforms and other websites decide what appears on their pages, CNN reports. Critics said the proposal amounts to censorship.

We’re watching you, part 2: In other U.S. government news, the Trump administration has asked a court to reauthorized a suspended National Security Agency surveillance program, targeting the telephone records of U.S. residents, the New York Times reports. The Trump administration wants to make the controversial phone records collection program permanent.

Not just the U.S. government: The Indian government wants Twitter to block what it deems is fake news by suspending eight Kashmir-based accounts for allegedly spreading rumors, India Today reports. Indian security forces have alleged that groups in Pakistan have attempted to divide the security forces in Jammu and Kashmir, areas controlled by India but claimed by Pakistan.

Even more watching: Technicians from Chinese networking vendor Huawei have reportedly helped government officials in Uganda and Zambia spy on political opponents, TechCrunch reports. News reports have Huawei technicians helping the officials spy on the use of apps like WhatsApp and Skype and Continue reading

Migrating ipSpace.net Infrastructure to AWS

I’m too stupid to unwind and relax over summer - there’s always some janitorial task to be done, and I simply cannot leave it alone. This summer, I decided to migrate our server infrastructure to AWS.

TL&DR: It went smoother than I expected, and figuring out how AWS virtual networks, public IP addresses, and security groups work while creating AWS Networking webinar definitely helped, but it also took way longer than I expected.

Robust learning from untrusted sources

Robust learning from untrusted sources Konstantinov & Lampert, ICML’19

Welcome back to a new term of The Morning Paper! Just before the break we were looking at selected papers from ICML’19, including “Data Shapley.” I’m going to pick things up pretty much where we left off with a few more ICML papers…

Data Shapley provides us with one way of finding and correcting or eliminating low-value (and potentially harmful) data points from a training set. In today’s paper choice, Konstantinov & Lampert provide a way of assessing the value of datasets as a whole. The idea is that you might be learning e.g. a classifier by combining data from multiple sources. By assigning a value (weighting) to each of those data sources we can intelligently combine them to get the best possible performance out of the resulting trained model. So if you need more data in order to improve the performance of your model, ‘Robust learning from untrusted sources’ provides an approach that lets you tap into additional, potentially noisier, sources.

It’s similar in spirit to Snorkel which we looked at last year, and is designed to let you incorporate data from multiple ‘weakly supervised’ (i.e. noisy) Continue reading

How to properly remove LuCi from OpenWrt

Overview

LuCi is a very popular OpenWrt web interface. For an average user, LuCi is probably one of the main deciding factors between giving OpenWrt a try in the first place, or moving on to another user friendlier firmware like DD-WRT.

If you’re an advanced user however, most of the times you may find yourself adjusting settings either through UCI or by editing the config files manually. In fact at one point you may realize you’re not using LuCi at all and it’s just sitting there idle. Basically a component that’s not only using resources, but also providing an extra attack surface.

Now, one could just disable uHTTPd to address some of these concerns, but LuCi installs too many dependencies, and cluttering a router with things that you’ll hardly ever use, is not the best use of the very limited storage space available in most routers.

Another method that some use to “remove” LuCi, is by issuing:
opkg --autoremove remove luci
This may seem to work, but in reality LuCi packages are not really removed this way and the related files will only be masked by OverlayFS. This is because the packages are built into the firmware itself.

While OpenWrt Continue reading

Netlify Migration

This blog is now hosted via Netlify, rather than GitHub Pages. It is still built using Jekyll, but I updated the theme to Mediumish.

I looked at switching to Hugo for site generation, but I hit several bugs trying to do the import, and theme setup was a pain. So I stuck with Jekyll, because it’s doing what I need. Using Netlify gives me a few more options around build and deploy, and moves away from Cloudflare.

All URLs and RSS feed should remain the same. Let me know if you see any issues.

Fast Friday – Mobility Field Day 4

This week’s post is running behind because I’m out in San Jose enjoying great discussions from Mobility Field Day 4. This event is bringing a lot of great discussion to the community to get everyone excited for current and future wireless technologies. Some quick thoughts here with more ideas to come soon.

• Analytics is becoming a huge driver for deployments. The more data you can gather, the better everything can be. When you start to include IoT as a part of the field you can see why all those analytics matter. You need to invest in a lot of CPU horsepower to make it all work the way you want. Which is also driving lots of people to build in the cloud to have access to what they need on-demand from an infrastructure side of things.
• Spectrum is a huge problem and source of potential for wireless. You have to have access to spectrum to make everything work. 2.4 GHz is pretty crowded and getting worse with IoT. 5 GHz is getting crowded as well, especially with LAA being used. And the opening of the 6 GHz spectrum could be held up in political concerns. Are there new investigations Continue reading
