sspiff··on Blink 1.0
This is amazing. I've been wanting to create something very much like this for ages, but never got around to it (because life).

Is there a contributors guide for the project?

sspiff··on Why do railway tracks have crushed stones alongside them?
Regardless of regulation, the same market shift has occurred in Europe. As someone who prefers low and light vehicles I can lament this, but we can only blame ourselves. Wagon and sedan sales have plumetted. Even the king of affordable cars, the hatchback is suffering, with mainstays such as the Fiesta and Focus being discontinued.
sspiff··on Why do railway tracks have crushed stones alongside them?
Most EVs will still be SUVs or crossovers, sadly. Even moreso than with current ICE vehicles.
sspiff··on Framework Laptop 16 Deep Dive: Display
Same here. I ended up getting a Zephyrus G14 in January, with all-AMD CPU and GPU.

If framework announced this laptop before I bought mine, I would probably have waited and stuck with my old junk until it became available.

sspiff··on Framework Laptop 16 Deep Dive: Display
What does "200%" resolution mean?

I prefer displays with a resolution where I don't have to do any scaling honestly.

sspiff··on Brute.Fail: Watch brute force attacks fail in real time
I do on my local network. Nothing that's on the Internet. I think it's still enabled by default on Fedora and Debian.
sspiff··on Same Stop: Life after 26 years as a programmer for Apple
In my experience, most of my coworkers have been passionate about some aspects of software development at least.

People aren't always passionate about the projects we work on at work, but most are passionate about things like software craftmanship, quality, or maybe just technology itself, or the problem solving aspect, or some are perpetually in love with how software allows you to create almost anything out of nothing.

sspiff··on The Great CPU Stagnation
It's hard to say without actually testing the hardware with a power meter, since throttling plays such a big role and power budgets advertised are often just a single figure approximation of a much more complicated formula.

I run a home server powered by a Ryzen 5800H, nominally a 45W part, but I've seen it maintain a power draw far higher than that for hours under sustained load.

sspiff··on The Great CPU Stagnation
This analysis is wrong because it is focusing on a limited number of high end chips.

You can buy CPUs that cost a fraction of any of those listed that will absolutely demolish even the best chips from 6 years ago today. All while consuming drastically less power for that performance as well.

Even mobile chips over 2 years old are within margin of error performance distance to those entry level Naples chips listed, at a fraction of the cost and power consumption.

I would not call that stagnation.

sspiff··on Intel One Mono Typeface
That looks so wrong. Why would they do this?
sspiff··on The Legend of Zelda: Tears of the Kingdom Release
That sounds more like a nightmare to me.
sspiff··on The Legend of Zelda: Tears of the Kingdom Release
I think it would make more sense for Nintendo to make a more powerful console on a compatible platform that isn't handheld, kind of like the Sega Master System/Game Gear or Sega Mega Drive/Nomad consoles.

So you can enjoy the same titles on the go as you can on the TV, and you could still use the Switch on the TV, but there would be an alternative for people who want a more high fidelity, fluid experience on a TV or a monitor.

It doesn't even have to be that much more powerful. Even when sticking to the same vendor, a 2018 Nvidia ARM chip had roughly 3-4x the CPU power and 10x the GPU power of the Switch, in a 15-60W power budget. This would be fine for a console that's always plugged into the power mains.

Going to more midrange vendors like Rockchip or Mediatek, or - and this is a long shot - striking a deal with Samsung for using their Exynos chips would probably yield a lower cost device but still net a 4-5x increase in gaming performance.

Emulation has proven that the games are not tied so tightly to their hardware platform for switching to a more modern architecture while maintaining compatibility to be an issue. Even without first-party involvement people have been running Switch games on mobile Android devices with a good processor.

sspiff··on Toshiba T1100 – the laptop that was named a milestone of electronic engineering
The hard drive equipped T1200 was the first computer I ever used. We had two of them at home as a kid after they were discarded by the ministry of public health where my dad worked as a clerk.

I had so much fun playing Keen on the slow blue-only LCD display, and just drawing stuff in Paint on Windows 3.11.

Sadly, I discovered as a teenager my mom (who never throws out anything, not even old newspapers) threw both of them out in perfectly working condition. I still get sad thinking about that.

sspiff··on Why is Apple's M1 chip so fast?
M1 is a 20W (max) CPU and a 40W SoC (whole package max).

However, in most intense workloads it doesn't go near 40W, more like ~25W under high load.

Still incredibly impressive.

sspiff··on Apple iPhone Supplier Foxconn Planning Deep Cost Cuts
I'm curious, feature-less in what sense?

Not an Apple fan myself, but everyone I've heard has praised the XR for basically being an XS with a cheaper screen.

Personally, I think the price points for these phones have become irrational. Supposedly their entry level model, the XR starts at €859.

sspiff··on Swedish Academy Won’t Award Nobel Prize in Literature This Year
Your comparison with corporations and nations is not entirely fitting. Money and words work out fine.

In the case of nations, we don't have to agree for them to be real. For example, China (the Peoples Republic of China) does not agree that Taiwan (the Republic of China) exists or vice versa, yet both are undeniably real. The same with Serbia and Kosovo.

Some things exist only because of convention or an agreement between people, like the value of a Nobel prize or money.

Other things exist because we can empirically prove that they exist, like protons and gravity. If we all agree that they don't exist, it doesn't make it so.

sspiff··on Darwin: a genomics co-processor provides up to 15,000x acceleration
Generally, blockchain "mining" requires a problem that is hard to solve, easy to verify. If I understand it correctly, the genome sequencing problem is hard to solve, hard to verify.
sspiff··on Cryptocurrency YouTuber Ian Balina hacked out of $2M during a livestream
At the risk of sounding pedantic, can we not use the term crypto for cryptocurrency or blockchain related stuff?

Crypto already has a well defined meaning that is in common use, which is related to cryptography, not cryptocurrency.

Edit: Post title was changed to use the full word "cryptocurrency", great :)

sspiff··on ReactOS releases 0.4.8 with experimental Vista/7/10 software compatibility
Sorry, I didn't intend to make it a code block, just wanted to indent the list headers. Is there a list syntax for HN comments?
sspiff··on ReactOS releases 0.4.8 with experimental Vista/7/10 software compatibility
I wonder if the planned Vista/7/10 support will extend to kernel mode drivers, especially for WDDM2 and up graphics drivers.

Currently, the supported graphics drivers is pretty sad for modern-ish hardware on ReactOS, because they are limited to drivers for Windows Server 2003 / Windows XP, which aren't available for a lot of modern cards (or integrated chips, for that matter). Additionally, a lot of the older XP drivers don't work well on ReactOS today.

sspiff··on ReactOS releases 0.4.8 with experimental Vista/7/10 software compatibility
I know a bunch of people (mostly gamers) who refuse to upgrade from Windows 7 to 8 or 10, mostly because of usability and privacy concerns.

Eventually, they'll have to (DirectX 12, but I'm sure there's a ton of APIs for non-games as well and drivers will stop being updated for Win7).

But if ReactOS can reach a level of maturity and compatibility to please such people, there's a sizeable niche there of people who:

  1. won't switch away from Windows to Linux or BSD,

  2. but would be willing to adopt a familiar and compatible operating system.
sspiff··on Power9 Benchmarks vs. Intel Xeon vs. AMD EPYC Performance on Debian Linux
I know this is about Power9, but these benchmarks really make me look forward to a time when companies will be ditching these first gen AMD EPYC processors on eBay for cheap. Good times are coming.
sspiff··on CSS Sans – A font created in CSS
They used CSS to create the font (presumably as an art project?), but it is available in plain OTF/TTF format, so it can be used as a normal font and doesn't need to be a barrier to accessibility tools.
sspiff··on Why are diapers so expensive?
This seems like a classic case of annecdotal evidence being extrapolated into general truth.

Two kids from an identical environment and sharing the same ancestors are hardly a significant sample.

sspiff··on Intel Fights for Its Future
Decelerating doesn't mean that it's no longer growing. It means that growth is declining over time, so growth today is less rapid than growth a year ago.

That doesn't mean that growth will stop, though it might.

sspiff··on OpenWrt in a WiFi card reader (2017)
That's true, but the port work described in this post is older (predating the fork of LEDE and OpenWRT), and the latest work regarding these zsun devices are more recent (but they haven't been upstreamed into LEDE, and so haven't been merged back into OpenWRT, either).

So the state of the art for these devices is a couple of months old LEDE builds.

sspiff··on OpenWrt in a WiFi card reader (2017)
I use one of these running LEDE.

For the original porting work done on OpenWRT, check this link: https://wiki.hackerspace.pl/projects:zsun-wifi-card-reader

For more recent work done to get up-to-date LEDE builds running on the device, check https://forum.lede-project.org/t/supporting-zsun-wifi-card-r...

sspiff··on New Zealand startup successfully launches rocket
> "Instead of paying hundreds of millions for a very big satellite in geostationary orbit, we now have new constellations of smaller — what we call nano satellites — in low earth orbit at much lower cost," he said.

So, what about earth orbit congestion/pollution caused by these "nano satellites"? Tracking a few thousand big objects is easier than tracking a few million small objects, I would suspect.

And if the cheaper launchers mean that smaller businesses or wealthy individuals will be able to launch their own nano-fleets, there's an increased risk of operator error or just malevolent operators as well.

Won't this just lead to more quickly exhausting the capacity of earth-orbiting space?

sspiff··on Meltdown Proof-of-Concept
How does this work for two instructions in the pipeline at the same time that refer to the same cache line? If the second instruction executes the read phase before the first is retired/committed to cache, you would be hit by two memory fetch latencies, significantly hurting performance.

I guess compilers could pad that out with noops to postpone the read until the previous commit is done if they know the design of the pipeline they are targetting. But generically optimized code would take a terrible hit from this.

sspiff··on iMac Pro's T2 chip
> For security reasons, the T2 is the iMac Pro hardware’s “root of trust,” and it validates the entire boot process when the power comes on. The T2 starts up, checks things out, loads its bootloader, verifies that it’s legitimate and cryptographically signed by Apple, and then moves on to the next part of the boot process.

How is this more secure from a locked down system using "standard" UEFI secure boot powered by any other TPM implementation?

I understand that this is not an in-depth technical analysis, mainly catering to the Mac-loving audience of the site and getting them to feel better about their platform of choice.

But I'd be interested to hear why I would trust this Apple T2 chip more than a workstation motherboard with a TPM on it, and secure boot on and loaded only with the keys of myself (in case I were to build my own kernel/bootloader and sign it) or a vendor I trust. I could be missing something, but the process outlined in the article sounds exactly like secure boot.
