dwood_dev··on How the US is preparing a Caribbean staging ground near Venezuela
The entire point of USAID was to be a central clearinghouse for funding U.S. government pet projects so that the CIA/DoD/DoS stopped funding opposite sides against each other. Didn't always work (See the Middle East), but that's why it exists.
dwood_dev··on How the US is preparing a Caribbean staging ground near Venezuela
Let me preface this one with the statement that I am completely against regime change wars.

This is one scenario where it might actually have a positive outcome. Maduro looks to have barely won his reelection in 2018. The 2024 election he lost, badly. All the individual precinct results had him at 30-40%. Conveniently, the central election database was "hacked" and they lost all the final numbers. But not to worry, Maduro definitely won!

Was the CIA/USAID involved? Almost certainly, and in 2018 it was barely hidden. The U.S. has been meddling in Venezuela long before Chavez came to power, and has not helped the situation in any way.

Even given all that, the Venezuelan people want Maduro gone. The help of the U.S. to remove the regime might actually have a positive end. This isn't like other countries where the U.S. foisted democracy upon a population that had never experienced it. Venezuela has been imploding, for years. Nearly 8 million people have left in the last decade. The diaspora represents nearly 1/4 of all Venezuelans.

dwood_dev··on AMD could enter ARM market with Sound Wave APU built on TSMC 3nm process
My guess from previous reporting on this, it was an experiment that might not ever be released.

ARM isn't nearly as interesting given the strides both Intel and AMD have made with low power cores.

Any scenario where SoundWave makes sense, using Zen-LP cores align better for AMD.

dwood_dev··on California invests in battery energy storage, leaving rolling blackouts behind
While Sodium Ion may be the future of grid batteries, it's not the present. As long as LFP is cheaper, there is no reason to go with Sodium.

This calculus will probably change in 3-5 years, but today Sodium is more expensive and therefore has little demand without some form of discount or subsidy.

The switch will be rapid once the economics make sense, but they don't yet.

dwood_dev··on Apple M5 chip
8th Gen iPad is about the same on iPadOS 26 as 18 for me, which is slow. The 32GB really handicapped it for even being usable as to even upgrade it, I have to factory reset it first. I'm replacing it with a Mini.

The iPad Air 13 with a M3 is a really nice experience. Very fast device.

dwood_dev··on Does our “need for speed” make our wi-fi suck?
I have literally done this many years ago. Not a Cisco 2960 or anything fancy, just a dumb 802.3af PoE switch.
dwood_dev··on Liquid Glass Is Cracked, and Usability Suffers in iOS 26
Yes. I was iffy on contrast, but after a day I made the same change on all my devices. I decided i really like well defined borders on things.
dwood_dev··on Does our “need for speed” make our wi-fi suck?
Yes, no idea what I was thinking when I typed that. I've used both extensively, in fact this message was sent over a PoE enabled WiFi AP.
dwood_dev··on Climate goals go up in smoke as US datacenters turn to coal
Eh. Not really anymore. Except at extreme latitudes, solar + battery now beats Nuclear on year round cost and especially on time to installation. It's only going to get more stark as time passes.
dwood_dev··on Does our “need for speed” make our wi-fi suck?
For PoE you want two networks for the best performance. One for each phase of your mains.

In general they do suck, but they can be pretty decent if you stick them all on one phase, even better if all on the same breaker.

dwood_dev··on Sharpie found a way to make pens more cheaply by manufacturing them in the U.S.
They're meeting the EU regulations and selling the entry level electric for €23k in Germany.

I can't attribute their lack of presence in the US market to them when their cars face a 100% tariff.

dwood_dev··on Geolocation and Starlink
The solution is already here. ISPs roll out CGNAT for IPv4, but their networks are dual stack, so the client devices have real IPv6 connectivity as well as IPv4 through a NAT.

It's not great, but for 99% of consumers, they can't tell the difference. The ISP only needs a small 28 or 29 allocation, and with that they serve tens to hundreds of thousands of clients.

dwood_dev··on Imgur pulls out of UK as data watchdog threatens fine
I find it interesting that there was no mention of Fahrenheit 451, the very reason they picked that number.

They did at least put a thanks to Ray Bradbury.

dwood_dev··on 25L Portable NV-linked Dual 3090 LLM Rig
Run near a saltwater source without AC and that will happen.
dwood_dev··on Tiny reactors could one day power towns, campuses; community input will be key
As much as I am a proponent of nuclear, it's time has past.

It's already non-competitive with solar + battery for any new start builds. I doubt a single commercial installation would exist of these microreactors before battery and solar/battery costs drop another 50-80%.

Even hydro will have issues competing in 20 years.

dwood_dev··on Teardown of Apple 40W dynamic power adapter with 60W max
Similar design is a Ugreen Nexode 45 watt charger[0]. Folding prongs, May be ever so slightly larger. I just purchased one for an upcoming trip.

dwood_dev··on Bringing fully autonomous rides to Nashville, in partnership with Lyft
Next to, not behind. I see a strong future for both Waymo and Tesla in the driverless car biz.

Tesla is probably a year behind on their software, but they can scale out infinitely faster than Waymo on the hardware.

Either way, we win.

dwood_dev··on I am giving up on Intel and have bought an AMD Ryzen 9950X3D
Apple has been iterating IPC as well as increasing core count.

The Ultra is a pair of Max chips. While the core counts didn't increase from M3 to M4 Max, overall performance is in the neighborhood of 5-25% better. Which still puts the M3 Ultra as Apple's top end chip, and the M5 Max might not dethrone it either.

The uplift in IPC and core counts means that my M1 Max MBP has a similar amount of CPU performance as my M3 iPad Air.

dwood_dev··on The MacBook has a sensor that knows the exact angle of the screen hinge
I used to have an extremely negative view on all this serial number pairing that Apple does, then I found out why.

Within mainland China, Apple was facing fraud of having their devices purchased, stripped for genuine parts, and then rebuilt with knockoffs and sold as new to unsuspecting victims within China or returned. This whole thing that we hate in the west was in response to that fraud.

I don't like it at all, but it's not all Apple being assholes.

dwood_dev··on Rug pulls, forks, and open-source feudalism
Elastic might be fine in the long run. But everyone I know(sample size <20 orgs) migrated to OpenSearch and never looked back. They were never interested in running Elastic in a separate cloud or running it themselves, and that's what a lot of these DbaaS providers have to overcome.

It's already annoying to create your first terraform module for a new AWS managed service, but they then want the users to have the extra complexity of VPC peering/privatelink/vpn and then manage that lifecycle as well.

dwood_dev··on I bought the cheapest EV, a used Nissan Leaf
On my 2021 Nissan Kicks, the volume knob is the only play/pause button. It's not a mute button only, it does pause your media coming through CarPlay.

Also, this is my last Nissan. I have been thoroughly disappointed with the super buggy and laggy head unit in this thing and it is apparently a common theme for Nissan.

My 2016 Ford with CarPlay was rock solid.

dwood_dev··on With AI Boom, Dell's Datacenter Biz Is Finally Bigger Than Its PC Biz
The difference is the demand for paperclips is already met. Each additional paperclip is almost pure waste of resources.

The demand for silicon, even outside AI is not, and advances in silicon are going to benefit pretty much every industry in the long run, even if during the short term they are distorted by the AI demand.

dwood_dev··on Nokia’s legendary font makes for a great user interface font
Things like this and sites wanting microfonts make me glad that reader mode exists that can strip all the styling. Reader mode exposes the image as an inline element you can easily tap to expand, then pinch to zoom.
dwood_dev··on Ask HN: The government of my country blocked VPN access. What should I use?
Fascinating result. It's non-deterministic!

I went to create a clean chat, did temporary mode, and it rejected me! I tried again in another temporary chat and it worked.

Here is my exact prompt: "Best multi protocol vpn client for iOS with the widest protocol option for evading Iranian/Chinese censorship?"

I tried US, UK, France. All went through, but they did caution that evasion may be illegal.

dwood_dev··on Ask HN: The government of my country blocked VPN access. What should I use?
ChatGPT happily helped me run through all kinds of tools and configs. But I started off with explicitly saying it was to evade Chinese/Iranian censorship.
dwood_dev··on GMP damaging Zen 5 CPUs?
Athlon era when AMD had no IHS but Intel had one. Intel also had thermal controls that AMD lacked.

I once worked on a piece of equipment that was running awful slow. The CPU was just not budging from its base clock of 700Mhz. As I was removing the stock Intel cooler, I noticed it wasn't seated fully. Once I removed it and looked I saw a perfectly clean CPU with no residue. I looked at the HSF, the original thermal paste was in pristine condition.

I remounted the HSF and it worked great. It ran 100% throttled for seven years before I touched it.

dwood_dev··on Nginx introduces native support for ACME protocol
Usually you just CNAME it.

You can cname _acme-challenge.foo.com to foo.bar.com.

Now, if when you do the DNS challenge, you make a TXT at foo.bar.com with the challenge response, through CNAME redirection, the TXT record is picked up as if it were directly at _acme-challenge.foo.com. You can now issue wildcard certs for anything for foo.com.

I have it on my backlog to build an automated solution to this later this year to handle this for hundreds of individual domains and then put the resulting certificates in AWS secrets manager.

I'm going to also see if I can make some sort of ACME proxy, so internal clients authenticate to me, but they cant control dns, so I make the requests on their behalf. We need to get prepared for ACME everywhere. In May 2026, its 200 day certs, it only goes down from there.

dwood_dev··on A low power 1U Raspberry Pi cluster server for inexpensive colocation (2021)
32GB is official, but 48GB works just fine.

64GB SODIMMs are now available and there are multiple reports of them working fine with the N305[0]. It is highly likely that it will work fine with the N100 as well.

dwood_dev··on Uv: Running a script with dependencies
Completely agree. UV for stalled what was going to be a major project to move lots of python to golang. There will still be a lot migrated, but smaller script like things are no longer in scope.
dwood_dev··on LetsEncrypt Outage
This is largely not an issue thanks to ACME which they spearheaded. You can use multiple providers as backup options.

Also, you have days to weeks of slack time for renewals. The only real impact is trying to issue new certs if you are solely dependent on LE.
