rvp-x··on Why does iron deficiency cause fatigue, even in the absence of anemia?
From blood tests, yes
rvp-x··on Why does iron deficiency cause fatigue, even in the absence of anemia?
I've noticed the same. I'm a woman so bleed often, I'd feel the fatigue but my blood work didn't show anemia, so my primary care physician didn't feel the need to prescribe it yet. I decided to take supplements on my own and monitor the ferritin levels to make sure I don't over-do it.

Note, if you aren't bleeding regularly, it's very unlikely you need it, and iron might be harmful. Make sure to test your ferritin levels before and regularly as you do it.

rvp-x··on Blood pressure e-tattoo promises continuous, mobile monitoring
This sounds fantastic. The blood pressure cuffs are very bothersome for anyone needing to do a 24-hour analysis. My mom did one and it would take a measurement every hour during night time and it was very hard for her to sleep through it. It would be tight enough some times to burst capillaries. And once an hour is a really low resolution.
rvp-x··on Fedora considers deprecating legacy BIOS
Fedora didn't even support UEFI on their cloud images before Fedora 35, released 5 months ago.

rvp-x··on One App – Two Worlds: This Is TikTok in Russia and Ukraine
I've heard explosions similarly far away (although it was at the coast and in an unusually quiet place). Explosions in the air travel really far. And every time I heard explosions so far I looked at the news/social media.

In one of these incidents the news article seemed like it might be a coverup to me so I looked up user forums in case someone leaked the real information.

rvp-x··on Mourning loss as a remote team
Not noticing doesn't mean the world doesn't care. There are a lot of reasons people vanish and it's harder to notice the absence of something than its existence, and people usually vanish for positive reasons, so I think nothing of it. I cried after discovering some people I hadn't known personally but were adjacent to me have died. I didn't notice their absence but I can empathize with the suffering they felt before their death, or the feelings of their family coming to grip with their absence.

While I have a strong emotional reaction to it, I don't think it's a bad thing, it is a part of life and a reminder for me to savor life.

rvp-x··on Chrome users beware: Manifest v3 is deceitful and threatening
Firefox will make it possible to upload manifest V3 extensions to their store (eventually). It's a good thing because it makes it easier to make an extension that works unmodified for both.

Chrome is additionally planning to remove support for manifest V2 as well, Firefox can't start to do this because they don't support V3 in their store yet.

rvp-x··on On Pegasus – NSO, Israel, and the World
They're "funding the israeli government/military" as much as a purchase from a US firm funds the US military - they're legally required to pay a tax and some of that money goes into the military.

Once released from the military these people have no additional obligation to pay for the military more so than people in more tame business - in fact, they might be seen as owed something for serving in the military, rather than the other way around.

rvp-x··on Ask HN: How to Get Better at Finishing?
I'd like to think I've been getting better at it. I find that I'm more familiar with what successfully finishing a task "feels like".

- doing the less appealing subtasks you've been putting off. it's objectively more difficult towards the end if you work this way.

- not treating "it works" as a finish line, remembering there might be more steps like code review, writing tests, and so on.

- avoid self-punishing comments like "I wanted to finish this on Friday and it's not done yet".

this often combines with the previous point - "I felt the task is done when it worked, but now I have to do all the tedious things like tests and I already declared it to be done on Friday!"

rvp-x··on A grim warning from Israel: Vaccination blunts, but does not defeat Delta
Remember that a third of the US is considered obese[1] and 10.5% of the population is diabetic[2], another common risk factor for covid.

You probably know a lot of people are in those groups.

rvp-x··on Zoom RCE from Pwn2Own 2021
FWIW it's possible to run Zoom in a web browser, but they make it annoying. https://techcrunch.com/2020/03/20/psa-yes-you-can-join-a-zoo...
rvp-x··on Is catching Covid now better than more vaccine?
This is the initial report that was published after two weeks: https://www.reuters.com/business/healthcare-pharmaceuticals/...
rvp-x··on Is catching Covid now better than more vaccine?
Here's a study with a sample comparing 596,618 vaccinated matched with the same number of unvaccinated people by my own healthcare provider:

https://www.nejm.org/doi/full/10.1056/nejmoa2101765

This healthcare provider is able to follow up on people with detail for a really long time - they are notified of any vaccination, PCR test result, hospitalization and death within the country. They've likely made it possible to calculate the same data for the current day within a moment's notice, and use this information for quick decision-making.

I would expect other healthcare providers in other countries to have pooled this information if they are able to do so (and possibly publish it too).

rvp-x··on Is catching Covid now better than more vaccine?
We have mountains of data about the current vaccine. This amount of disease-tracking is unheard of. Almost any institution in the world has regular discussions about this singular disease. Governments spend huge resources to pinpoint the exact minimum measures that can control the spread enough.

My country attempted a 3rd dose, and within 2 weeks they were already reporting data on reduced risk of catching the virus in comparison to 2, 1, and 0 doses. These are studies done with sample sizes of millions of people.

I am under the impression that a lot of places consider recovered cases as equivalent to fully vaccinated.
rvp-x··on A Short Guide to Iraq (1943)
There were so few european settlers in the area before 1948 that they managed to defeat the armies of multiple neighboring countries!
rvp-x··on Many temptations of an open-source Chrome extension developer
Note that browser extensions are reviewed by humans, as are updates to them. You also need to pay a nominal fee ($5 by credit card) to submit an extension to the Chrome store, to avoid spammers.
rvp-x··on Illumos to drop SPARC Support
ACPI is problematic in big endian.
rvp-x··on Playlist for iOS
NewPipe isn't on the Google Play store. I assume that this app can't be either.
rvp-x··on Jump in cancer diagnoses at 65 implies patients wait for Medicare: study
US healthcare is severely under-performing in comparison with other systems. https://ourworldindata.org/the-link-between-life-expectancy-...

People should acknowledge the system as flawed and not have market ideals stand in the way of fixing this flawed system.

Another note is that universal healthcare does not imply government-run healthcare. I live in a country which is an example of this - Israel.

rvp-x··on Suez Canal says traffic in channel resumes after stranded ship refloated
Israel at some point was considering setting up a rail track between Eilat and the rest of the country. The main benefit of doing so is that cargo ships could unload and Eilat (red sea) and have cargo transported to a port in the mediterranean sea. https://en.wikipedia.org/wiki/High-speed_railway_to_Eilat

That plan was frozen after the Egypt-Israel peace agreement.

rvp-x··on Satellite imagery shows Northern California kelp forests have collapsed
Almost everything you describe is a product of bad urban/house planning.

House planning could require far less electricity, but it's not required by building codes, and the market doesn't acknowledge its value.

Urban planning puts workplaces far away from residential areas because they used to be heavy polluters, but never stopped doing it when workplaces improved.

My workplace office is 1km away from my residence. Someone had the smarts to put a small amount of office buildings in an otherwise residential neighborhood (as well as a few shops). I moved here for the job - it was the obvious choice.

Mixed use zoning has made it so I don't just not need a car, I don't even use public transit often.

rvp-x··on Show HN: Khan-dl – Khan Academy Course Downloader
My initial gut feeling was your response, but changed my mind quickly when reading the article. His videos being online resulted in interaction with the students, and that's where he harassed them.

It's a shame, but any other solution feels like it's a broken stair just waiting for someone to trip over it.

rvp-x··on Future Plans for Autotools
People still use macOS, which is the main reason I see "please add libtool support" these days.
rvp-x··on When Amazon Switched from Sun to Linux
All of the BSDs have 64bit off_t, they had to break the ABI for the BSD lawsuit settlement anyway and used that opportunity to make this change.
rvp-x··on LibreSSL Languishes on Linux
The biggest problem you would have is that they share the function names, and if you have this tree (where a line means "links with dynamic library"):

   [my binary]
  /           \  
[___libA___] [___libB___]

  |            |
[libreSSL] [OpenSSL]

then they will have some conflicts (some refer to this as "spewing nasal demons"). Suppose that they both have a function called mutex_lock that touches a global, but OpenSSL added an extra field. Now the behaviour is dependent on which one is picked first. Surprise segfaults? crashes only on strict alignment platforms? unlocked behaviour because the global is named something else? All of these can easily happen.

ELF doesn't have any builtin namespacing, and when compiled with C normally, the C compiler doesn't modify the names to create something like namespacing in the way other languages do.

If you make an extra effort to put them in different places (preferably not in the default linker lookup path and using something like a per-executable RUNPATH rather than a global ld.so.conf to find it), you can have conflicting libraries. But you are playing a dangerous game which wastes everyone's time and effort.

rvp-x··on CVE Stuffing
Huh. I wonder if it's a student doing an assignment and not realizing they're submitting to a real database.

Their other GitHub work is following tutorials, labs and courses.

rvp-x··on Things I Didn't Learn in 2020
I do. I suspect people vary wildly by how often they do meetings and what they use them for. For me, most conversations are done in text, and most video meetings are regularly scheduled and 15 minutes long.

Having a webcam on for longer meetings is tiring, because I feel less free to change my position and move around. But it's okay for a short meeting. I make sure I look reasonable beforehand.

rvp-x··on Insulation: First the body, then the home (2011)
my feet can be cold even under a proper winter blanket. in my case, it's a symptom of iron deficiency anemia. it can also be bad blood circulation for other reasons.
rvp-x··on Am I Disabled?
this sounds really bad for you :( there's nothing wrong with not being productive sometimes. you shouldn't need like you need to "catch up" by doing insane amounts of work.

This mentality totally screwed me over during university, and I feel like a lot of my mental stability right now comes from how my job place has guilt-free discussions about what we can finish in the remainder of the time until the deadline, without "oh we'll just work harder".
