epall··on Case Studies in USB-C Debugging (2020)
This work seems so much more challenging, interesting, and fun compared to what I do as a senior software engineer. Why does hardware engineering pay so much less??
epall··on Intuit asked Mailchimp employees to pay medical costs out of pocket
Most employers in the U.S. over about 1,000 employees are “self-insured”, meaning they hire the insurance company for the network and administration, but the company actually does directly pay out claims. At over 1k employees, I expect MailChimp was already self-insuring, and Intuit definitely does.
epall··on Land Gained and Lost: A Fermi Estimate
No mention of permafrost? Yes, the _air_ will be more habitable, but if the _ground_ is a boggy mess, you’re not going to be doing much with this newly habitable land.
epall··on Towards an HD44780-Based Video Mode
This is brilliant! Check out the demo video at https://www.youtube.com/watch?v=nxFad7Rxw7Q
epall··on Windows for Arm on M1 Mac Successfully Virtualized
I get the sense that hyperscalers don’t give Intel a ton of margin in negotiations, so they already have access to great server chips at competitive prices. And they’re bringing in AMD now to compete. Where M1 really shines is client-side applications like video handling, ML inference, and crazy branchy nearly single-threaded code. Servers can afford to run much lower clock speeds (see GCP n1 family, for example) because web serving is an embarrassingly parallel problem. Sure, some ARM might help lower costs of internal things like S3, but Graviton2 isn’t that incredible compared to the M1-vs-Coffee Lake comparisons going on in the laptop world.
epall··on Osborning the Mac, or not
I’m rather happy about buying the recently updated 13” MBP and basically skipping ARM Macs. My last one lasted 8 years, so I expect this one to last roughly as long. By then they’ll _definitely_ have ARM figured out, and in the meantime I can continue enjoying x86 compatibility and VMWare. For the fairly small segment of the market that we devs represent, I suspect I’m not the only one here implementing a _reverse_ Osborne Effect. Get your x86 Mac while you still can!
epall··on Apple’s Mac Chip Switch Is Double Trouble for Intel
This is essentially what RISC-V does with its "Compressed" instruction set, except without the dictionary switching. They pulled a bunch of statistics over real-world machine code, ran it through compression, then reverse-engineered that compression to make something a bit more sensible to a compiler writer. I think this will work out vastly better than the haphazard patching of e.g. Thumb on ARM.

epall··on Google App Maker Shutting Down
Oof. This really hurts. So often when folks complain about Google shutdowns, I defend G with “but that was a consumer product! GCP doesn’t kill off things. It’s different.” But here we have Google Cloud (in my defense, not GCP) killing off a powerful, proprietary Enterprise product with no viable migration path. At least folks get a year to migrate off, but that’s a lot of sunk cost.
epall··on Linus Torvalds on Why ARM Won't Win the Server Space
I love my ARM-powered Chromebook. True, it can’t teally do native development, but ARM clients aren just coming. They’re here. And wow doesn’t have amazing battery life and an unbrickable OS.
epall··on Using GnuCash as a Freelancer to Track Finances and Prepare Taxes
Check out Tiller! https://www.tillerhq.com/

I tried going down the route of dealing with OFX in GNUCash, and it's just a huge never-ending hassle. Tiller dumps the raw data from Yodlee (the backend that does the gnarly interfacing and cleaning for most PFM sites, besides Mint) into Google Sheets. From there you can use Apps Script or the Sheets API to push the data wherever you want. Sure, it's $5/mo, but well worth it for not ever dealing with bank websites or APIs or OFX formats again.

epall··on The Uninhabitable Earth
Methane deteriorates in the upper atmosphere fairly quickly, whereas CO2 sticks around. Methane is a dramatically better insulator than CO2, so in the short run its impact is higher, but when you stretch out the timescale, your methane is deteriorating while the CO2 sticks around, so the relative impact tilts slowly toward CO2.

It'll always be missing a bunch. Feel free to add them as proposed edits!
epall··on ASUS Launches Raspberry Pi-Esque 'Tinker Board' with 4K Support
Great idea! Thank you.
epall··on ASUS Launches Raspberry Pi-Esque 'Tinker Board' with 4K Support
Thanks! It's in there (row 21), but I got the price wrong.

Sweet! Another compelling option for sub-$100 SBCs. I've been keeping track of them in a Google Sheet at https://docs.google.com/spreadsheets/d/1TCugLk0GSukeWjhsLu73....
epall··on Salesforce buys word processing app Quip for $750M
According to CrunchBase, they've only raised $45M. 16x return after 4 years in business. Well done!

epall··on Hologram: taking EC2 Instance Roles everywhere
The difficult part of separate AWS accounts is that connecting between them is tricky (Security Groups, VPC, etc.). Not impossible, but a pain to get right. The spectrum between dev and prod isn't so clear-cut for a business with petabytes of data: you often want to develop systems against production data (read-only, of course), and having two copies of the data can be prohibitively expensive. Of course, with the appropriate access policies you can share the data safely, but then what about that IRC server that was non-production but then wound up part of the deployment flow and became mission-critical?
epall··on Hologram: taking EC2 Instance Roles everywhere
Yeah, we connected with LDAP because that's how AdRoll operates, but we'd like to support a more universal backend eventually. That support just didn't make the cut for open-source release. With a bit of code, you could easily plug in a .txt file or a SQLite database, or even etcd if you really don't want to move a file around.
epall··on Hologram: taking EC2 Instance Roles everywhere
Yeah, when we spoke with Amazon, they already had a couple of labels for what hologram is, so it sounds like we at AdRoll are not the only AWS customer who has had to roll it ourselves. Hopefully we'll be the last!
epall··on Hologram: taking EC2 Instance Roles everywhere
The hologram server is privileged and should run behind a firewall. It will only hand out keys to successfully authenticated (using an SSH challenge-response) clients, so it could be publicly accessible, but why go to that risk?

The hologram agent that runs on your laptop, and could potentially be exposed in a cafe, attaches to lo0, so there's no way somebody on your coffee shop wifi could get the creds.

epall··on Google Fiber Austin
Yeah, at least for my building (which I'm heading up the internet committee for), the BPON that was installed by AT&T can do max 600 Mbps for about 30 customers on a loop, so that's 20 Mbps each. They should be able to burst higher than that when it's not saturated, but they haven't bothered to turn it on.

If you're in our building, you're in luck, though: the HOA is amenable to laying CAT5, so if things go well, we may have Webpass by the end of 2015.

epall··on On June 6th, World IPv6 Launch Will Change The World Forever
I've tried and failed to set up IPv6 on my MBP a few times now. HE seems to provide free tunneling, but I can't figure out if it's compatible with my AT&T U-Verse RG.

Is there a way to enable IPv6 tunneling on OS X in a way that doesn't require firewall configuration?

epall··on Mayor Bloomberg Will Learn How To Write Code In 2012
They have a web-launched SaaS version, too, and they're trying to get everybody to switch to it because the pricing model is per-user instead of per-machine.

epall··on How much money do you really need to start your company?
I'm a fan of bootstrapping, but it's not always an option. Plenty of opportunities in consumer require a critical mass before you can start making money. These are the kinds of plays that make sense when VC is flowing more freely. For some businesses, it really does take 10 developers plus 5 others working for a year to hammer things out. That clocks in at $2-3 million, which just so happens to be a reasonable Series A.
epall··on Fast Two Way Sync with Unison, Lsyncd and Autossh
For ultra-fast one-way sync, I built Dripbox: https://github.com/epall/dripbox
epall··on On Bushido, launch apps from github repos
As one of the maintainers of a small open source project (http://getontracks.org/), I see a huge opportunity with Bushido. The project has really struggled with making it easy for new users to start up, but even a tutorial doesn't help non-technical users. A few people have set up hosted versions of Tracks, but getting them to stay up-to-date with progress on trunk is a challenge.

With Bushido, projects like Tracks finally have a clear route into the hands of non-technical users. Sure, I can go set up a hosted version of Tracks, but then I'm taking responsibility that, as a part-time maintainer, I have no interest in. This rocks!

I built something like this for Caltrain: http://epall.github.com/animated-caltrain/
epall··on AT&T to Acquire T-Mobile USA for $39 Billion
And for only $6/month! Best iPhone plan ever.
epall··on AT&T to Acquire T-Mobile USA for $39 Billion
T-Mobile customer service has consistently been one of the best customer service lines I have ever dealt with. Back when I had a Sidekick, I would routinely end up connected to a Danger employee sitting _at_ Danger HQ, helping me through teething issues on the early Sidekicks. For over five years, they have been extremely polite, helpful, and available.

From what I've heard, I won't get this kind of service as an AT&T customer. I'm sad to see T-Mobile go, but this merger always was kind of on the horizon.
