Using a #VPN or #Tor to access #Twitter in Brazil is risky.
Your ISP can inspect packets to see if you're using a VPN or Tor. This isn't difficult. They can't see what data the packets are protecting, but knowing you're using a VPN or Tor is obvious.
If your ISP knows further your public Twitter account and can correlate VPN or Tor packets with your public Twitter activity, then it's clear you're using the VPN or Tor to access Twitter.

Agreed.
I was auditing some internal documentation for staff generating SSH keys, which includes setting up PuTTY on Windows. Noticing the *DSA key types had me slightly surprised given that PuTTY 0.81 was released on 2024-04-15. OpenSSH deprecated DSA in 2015 and will have it fully removed by 2025.
https://lwn.net/Articles/958048/
I was also kind of surprised OpenSSH doesn't have any quantum-safe client key types, even though the daemon supports NTRU Prime sntrup761 and X25519 with SHA-512.

2024-08-05 22:08:03

Curious.
PuTTYgen supports the following SSH key types:
- DSA
- RSA
- ECDSA
- EdDSA
- Ed25519
- Ed448
OpenSSH supports:
- RSA
- ECDSA
- ECDSA-sk
- Ed25519
- Ed25519-sk
Given that the overwhelming majority of #SSH servers are provided by #OpenSSH, it's unfortunate that the two projects don't agree on key types.

This Venezuelan election vote analysis on Reddit is amazing.
The results are:
Maduro: 51.199997%
Gonzales: 44.199998%
Others: 4.600003%
Almost exactly 51.2%, 44.2%, and 4.6% on the nose.
Why? If you skew the votes in your favor, then you could do something by picking a winning percentage for yourself and losing percentages for everyone else.
EG, of 10,058,774 votes,
51.2% = 5,150,092.288
44.2% = 4,445,978.108
4.6% = 462,703.604

I can model tossing dice and flipping coins very easily and cleanly.
For example, 256 flips of a fair coin, recording "H"/"T" per flip, then hashing the result with SHA-256 should work.
I can prove the coin is fair, show the entropy per flip (1 bit), save the raw flips as well as the post-processed SHA-256 hash.
It meets all of the requirements in NIST SP 800-90B, althoug cumbersome. So it should work, no?

2024-07-30 22:38:38

What is the NIST-approved way of getting random numbers?
NIST SP 800-90B mentions how the HWRNG should preform, testing, validation, access to raw and post-processed (optional) data, etc.
But doesn't mention specifically what sources are valid.
- Does mashing on the keyboard collecting nanosecond-precise key press times work?
- What about rolling dice or flipping coins?
- USB HWRNGs?
- Video cameras, microphones, RTL-SDR, etc.?

The blog post doesn't really show the GPS weirdness at Null Island however. If you look at a heat map of GPS traces from athletes who have recorded activities on Strava, this is what it looks like.
This happens because they started recording their activity before they had GPS lock. So the activity records (0.000000, 0.000000) for latitude and longitude coordinates.

An approach I prefer is to generate a random password/passphrase that meets the security requirements, then prepend/append the number of characters/words.
EG, "e\A(."bR|@" is 10 characters long, so "e\A(."bR|@10" is guaranteed to meet the requirement without weakening security.
Similarly, "redeem robot louse apathy match eva" is 6 words long, so "6 redeem robot louse apathy match eva" is also guaranteed to meet the security requirement.

To help motivate this, consider the following: I have two d60 dice. On one of the d60, every number is randomly and uniformly distributed through the die. The other, the numbers are in numerical order in a spiral out design with adjacent faces.
Both d60 are machine precision balanced and perfectly fair.
Which die produces more random results when tossed? The randomly distributed d60 or the numerically ordered d60?
Spoiler alert: the toss determines how the d60 lands, not what's printed on it.

I've audited a lot of password generators. One thing I see come up occasionally is shuffling the source characters or word list before using a CSPRNG to pick one at random.
For example, something like (pseudocode):
chars = digits + lower + upper + symbols
chars.shuffle()
chars[rng.randint(0, chars.length - 1)]
Shuffling the source character set doesn't increase the entropy of the generation process.
A CSPRNG picking from an ordered list is just as random as one picking from a shuffled list.

Recently, one of the drives failed I think primarily due to heat. I replaced that drive today, but decided I wanted something to manage the heat a bit better.
My employer had some aluminium scraps that I could rest the drives on, lifting them off the desk, improving airflow. But being aluminium, they'll also absorb any heat the drives put out.
I also put a USB fan above the drives for cooling. Hopefully this improves lifespan.

Nvidia is moving to fully #OpenSource #Linux kernel modules.
This sounds like good news on the surface, but what they're not telling you is that the kernel module still relies on the GPU System Processor (GSP), which is firmware running on the card itself. The kernel module won't be doing work, just interfacing with the hardware so Linux users have less headaches moving forward.

I should have realized an exponential function (orange) would fit better than a cubic (blue). Thus:
y = 0.0284598 × 3.62961^x + 1.54071
Unsurprisingly, this has a better R² value of 0.9998.
It makes sense, because every zone should weight higher *per percentage difference* than the previous zone.
This is not true with the cubic between training zones 1 to 2 and 2 to 3. It is true with every zone using the exponential fit.
Anyway, I still haven't heard anything from the researchers.

I should mention one more thing: that cubic assumes the same power distribution curve as the world class elite cyclists, which obviously won't align with recreational cyclists.
The paper doesn't address how to setup your training zones such that it meets the requirement of strictly increasing zone percentage differences.
No doubt it'll be based on your power distribution curve, but that also means ignoring every training zone provided by coaches, software, books, other papers, etc.

2024-07-12 16:21:41

Obviously, spending 100% of my time in zone 3 should score higher than spending 100% of my time in zone 2, which further should score higher than spending 100% of my time in zone 1.
But when that cubic is applied instead of using the zone percentage differences, then the zone score breakdown becomes:
Zone 1: 6.92
Zone 2: 9.12
Zone 3: 10.15
Zone 4: 26.90
Zone 5: 76.30
Much better.
I reached out to the researchers. I'll update this thread if they respond.

I found a cubic equation that fits the data in the paper with an R² value of 0.999264, which is phenomenal. It is:
0.7225x^3 - 4.48536x^2 + 8.96214x - 3.578
Where "x" is the zone number.
This works regardless of how your zones are setup, meaning their percentage differences don't need to be strictly increasing.
For example, if I spend 100% of my time in a zone, the PPi values for my #running training zones become:
Zone 1: 81.64
Zone 2: 46.65
Zone 3: 41.79
Zone 4: 54.58
Zone 5: 235.86

This adds to the list of training scores:
- TRIMP (Banister's OG and Edwards', Lucia's, and Stagno's variations)
- RSS (Stryd)
- TSS (TrainingPeaks rTSS, hrTSS, etc.)
- HRSS (Elevate for Strava, normalized hrTSS using TRIMP)
- SRPE (Foster)
- Fitness, Form, & Fatigue (Strava)
TSS is the gold standard due to its simplicity and the elegance of not needing weighting factors.
SRPE however has shown to be the most reliable at predicting performance.
PPI might be more reliable than SRPE however.

2024-07-11 21:41:51

This is exciting to me as a runner, because this could obviously be extended to #running for those who run with a power meter.
However, as demonstrated in the paper, the power zone percent differences must be monotonic, otherwise the metric is not reliable.
So #Stryd, instead of picking zones arbitrarily, they should be based on your own PDC.
Also, the weighting factor "K" will need to be re-evaluated for runners due to the different metabolic demands running has versus cycling.

2024-07-11 21:39:28

This is an interesting paper than creates a new training score called "Power Profile Index" or "PPI".
It weights activity stress based on the amount of time spent in each training zone. In the paper, 6 #cycling zones are modeled.
What's the most interesting to me is that it doesn't prioritize volume, but rather intensity. Things like time trials, elevation grades, flat easy efforts, etc. drive the score, not time in the saddle.

I'm not a #NixOS user. I've never installed it. I've only seen discussion about it on Reddit. I'm vaguely familiar with its intended audience and purpose.
But this purge is wild. I mean, you can't separate politics from software. Software is inherently political strictly because the developer who is writing it has political opinions which will inevitably make it into their project.
But for the vocal minority to overwhelm a project, its founders, and core devs? Wow.

Useful for hills and wind. I can keep the effort consistent and let the pace be variable.
Useful especially for races. If I know I can hold a certain power for the duration of the race to hit a goal time, then regardless of the gradient, if I stick to the target power, I'll hit my goal without blowing up.
It's also more responsive than HR for speed work. Even though I'm more likely to target specific paces, targeting by power can be useful in a training block also.

What's weird, is Eliud Kipchoge is sponsored by Coros and Courtney Deauwalter by Suunto.
Both are elite endurance runners that have wide influence in the running community. Yet, it seems that most runners still prefer Garmin or Apple.
Suunto and Coros seem to be not be understanding the right way to capitalize on their sponsorships if finances are the concern.

So armed with that, if you setup a new #Stryd account, I recommend setting your weight to 100 kg.
Thus, when your watch is showing you #running at 403 W, you know you're actually running at 4.03 W/kg. The math is trivial. Just move the decimal two places to the left.
Same with PowerCenter. If your CP is 415 watts, you know you should be able to sustain 4.15 W/kg for about 40 minutes.
This would be a good 10k race prediction tool to have in your chest, don't you think?

This isn't surprising. Losing excess body fat is a great way to improve #running performance. It's something you can control. It just makes predicting race times challenging.
Now suppose I use the same calculater, but this with with 4.2 W/kg as my FTP/CP. Then it doesn't matter what my weight is, my marathon finish time ranges from 3:03:59 to 03:13:39.
W/kg shows effort in the run, not total work averaged over the duration. This is the key difference.
Yet #Stryd is all-in with Watts.

For example, when using Steve Palladino's Super Power Calculator to predict race times, it is 100% dependent on weight when using watts.
If I wanted to predict my marathon finish time, and I knew the following:
- Weight: 80 kg
- FTP/CP: 320 W
- Riegel exponents: -0.08 to -0.10
- Target RE: 0.99 to 1.01
I can expect to finish between 3:14:00 to 3:24:27. But if my weight drops to 75 kg, all else equal, I can expect to finish between 3:00:52 to 3:10:18.

TL;DR- When you change your weight in #Stryd, you can no longer compare current runs to past run, must immediately update your critical power, and wait 90 days before the runs with the old weight are outside of their calculations.
IE, it's problematic *for their own platform*.
This could be solved though if they standardized on W/kg. Not only do the past problems disappear, but race calculations, training predictions, and just all around post-run data analysis, becomes easier.

This has been an interesting morning for me regarding #running. I already shared the news about the #Suunto layoffs. Now it's time to rant about #Stryd.
First, let me be clear: I love my Stryd pods. They will be immediately replaced if damaged, lost, stolen, or dead.
But what irritates me most about the Stryd ecosystem is their integration of watts (W) rather than watts per kilogram (W/kg).
The problem is changing your weight, as per this Reddit thread:

I plan on running my 9 Baro into the ground (pun intended)—it was just too expensive. But I'm keeping my options open on a replacement, and if you were to ask me right now, it would be between Garmin and Coros.

Garmin, Polar, Coros, and Apple don't have these problems.
So if it takes firing 76 employees to become more agile, responsive, and productive towards making robust software and firmware for their watches, then I'm here for it. I don't care about the deep Finnish roots and pride of Suunto's history. What I care about is a watch that doesn't feel like an expensive beta test.

But their firmware leaves a lot to be desired. In both by Ambit3 Peak and 9 Baro, I have a hefty list of irritants, that each individually don't amount to much, but on the whole, make using the watch feel cheap and rushed out the door.
For example, #Suunto is well known for zero-drops while recording an activity, where the watch just doesn't record any data for a second or more. UI sluggishness, poor auto-lap detection, dim display, button press lag, Bluetooth pairing woes, etc.

#Suunto just fired 76 employees out of 300 while moving part of production and part of development to China. Here's my take.
Suunto is known for their robust hardware. They historically have designed watches specifically towards mountaineers and alpinists. I purchased my first Suunto in 2001 before GPS watches existed. It is stainless steel, taken a beating, and held up beautifully. It's very clear what their mission was. These watches are built to last.

That's exactly my daughter! She's corrected a number of people about the difference between Tyrannosaurus Rex and Allosaurus, how Brontosaurus never existed, how dinosaurs are not lizards, and why pterosaurs are not dinosaurs.

Haha.

2024-06-20 01:27:39

My daughter has always been interested in dinosaurs, since like 3 years old. She could trivially name off each of the epochs, dozens and dozens of dinosaurs, where they lived, what they ate, where to find fossils, etc.
As an off-hand comment, I mentioned we have evidence to suggest that some dinosaurs were warm-blooded and perhaps some even hot-blooded.
I've just shaken her whole world.
She's now deep in the Internet looking up everything she can about warm-blooded and hot-blooded dinosaurs.
