The Liberty Phone 3 years ago

It's meant to run GNU Linux instead of Android, so maybe the 4GB RAM might be ok?

Definitely not enough if this was running Android. RAM usage on my Android right now: - 2.1 GB Android OS - 1.0 GB Google - 0.5 GB Android System - 0.5 GB Firefox - 0.4 GB Android System Intelligence - 0.4 GB System UI - 0.4 GB Google Play services ... and a bunch more < 0.1 GB services that seem necessary

I was trying to figure out why the update wasn't working on my Archlinux box. After a few attempts I barely caught a glimpse of an error message that flashed by: something along the lines of "unzip not found".

After installing unzip, the firmware updated successfully.

Video games are more enjoyable with the increased processing power!

Where the 2018 model struggles at high frame rates, the M1 version enables more fluid gameplay at 95-120fps. The new M2 would likely deliver more consistent 120fps performance given the advertised 15% CPU and 35% GPU uplift.

focus on the basics instead of marketing gimmicks

This reminds me of what Steve Jobs said about Xerox[0]. After achieving market leadership in their industry, engineering at iRobot seems to have been pushed aside in the company's decision making process.

Is this a consequence of being a publicly traded company? After all, pushing consumables and subscription services requires less capital and makes more money compared to developing a better robot. The $1.7B exit seems like a good outcome for a stagnant (relative to its peers) company.

I use a few secondhand Netgear R7800 with OpenWrt installed to blanket the house in fast WiFi and 1Gb Ethernet. This setup has been in place for almost 4 years now and has been very reliable. Maintenance is needed to keep software up to date.

With so many radios, I've segregated IoT devices on their own frequency to maximize throughput on workstations. VLANs provide network isolation.

I think the routing performance is fine for most households. If you need a router that does QoS on a gigabit internet connection, you'll need something more powerful.

Occasionally I'll wish that I had something faster than 1GbE, so the hunt for hardware continues...

Be careful as this syntax can potentially introduce SQL injections.

PHP's parameterization features in PDO can be abstracted so you can turn this into:

  $vars = array(":userid" => $userid);
  q("select name from users where id = :userid", $vars);
It's still pretty concise and is much safer.

Wireless charging isn't immune to failures either. A recent example of this is Google's Pixel 4 device, introduced in Oct. 2019. Apparently if the phone chassis expands over time, the rear antennas (including wireless charging and NFC) get disconnected and stop working. People experiencing this issue, including myself, are not able to reliably use wireless charging, and using NFC (e.g. for Google Pay) requires us to put pressure on the rear of the phone.

Granted, Apple seems to have much better hardware quality control than most vendors and iPhones might not ever have this issue.

I had a similar plan when I started my career, where the idea was to save and self-support independent endeavors.

13 years later: I can execute the "full plan" at any time, but I find myself to have sufficient autonomy and be comfortable enough at my current position.

This plan is certainly not the highest payoff in my case, as I can't buy the toys/houses my peers have. However work/life balance is great, and I still have the option to build things without needing outside funding.

Splitting a battery into two cells might mean it can charge twice as fast in parallel.
