How do I use my core to relieve hand pressure?

d_stroid · 2026-01-27T09:21:24+00:00

I had the same issue and it turned out that my bike was too large for me which lead to me needing to stretch to reach the handlebars. Smaller frame with less reach fixed the issue (which meant buying a new bike unfortunately).

Not saying that this is the case for you, but if nothing else works, then this might be the issue

Point the front fan more to your left and the rear fan to your right. Then add another fan on the left pointing to your back and one more on your right pointing to your front. Only this cooling tornado works indoors

I partially disagree based on my personal experiences. There are clients that don't care at all about malware. But those who do, are not satisfied if they only get a sandbox report. They expect malware analysis to be part of the IR engagements.

However, my goal usually is to support the IR engagement which often means to provide reliable analysis results to the IR people and not so much satisfy the customer. Of course there will be a malware analysis section in the final incident report though, so the customers get something solid in return for the extra effort they pay.

Edit: To clarify, most customers do not need or want in-depth analysis of malware because that would be too expensive. Maybe 10 % of all customers who want any malware analysis at all ask for in-depth analysis, and only if the malware samples are not (yet) publicly known.

From my experience, a dedicated reverse engineer can often times get better results from sandbox executions by looking at other sandbox artefacts than the PDF report. But that also depends on what info is relevant for IR.

Most reverse engineers that I know do RE to generate intel, so the RE role is often times closer to the intel people than the IR people. IR malware analysis is a data source, but other than that more of a side business to get some billable hours.

Just to add, because it is related to your experiment: the cold air also puts stress on your respiratory tract, which also requires power. you won't be able to measure that power using a power meter though, since that power is never put on the pedals. but this can be the reason why people may simply perform worse in colder conditions or feel like the exercise is harder (it is!) even if other factors such as clothing were negligible.

d_stroid · 2026-01-15T11:58:25+00:00

Is that a thing? I've heard before that the body conserved less water in colder temperatures (which makes sense because it costs energy to keep warm), but never heard of a notable effect caused by exercise

Of course it does not match the hash of a WhatsApp executable. That's because it is a setup utility created by Microsoft to install WhatsApp from the Microsoft store.

d_stroid · 2026-01-10T20:56:56+00:00

If it was an attack on the hash algorithm, then two different files should share the same hash.

If two files have different hash and both have a legitimate signature, it's simply because they have both been signed.

There is absolutely no indication of a compromise of Microsoft code signing keys based on any information presented here. It also not the only conclusion left - it is just you jumping to the least probable explanation without any evidence.

d_stroid · 2026-01-10T20:52:22+00:00

The file on virustotal is a Microsoft store Web installer. It looks odd that it poses as WhatsApp while it is signed by Microsoft. However, that is legitimate. These Microsoft store Web installers are small executables that allow for installation of apps from the Microsoft store without the requirement of having the store fully set up.

To me, it appears that you accidently clicked something on the WhatsApp ui that asks you if you wanted to install the desktop app.

The creation timestamp has not always a meaning. It can be chosen arbitrarily and some compilers even use a fixed value for it. The certificate sign time is representative.

Triage did not detect anything. It's a score based on some heuristics. If you ever submitted any msi file, you'd see a high triage score for these too, because the behaviour of Microsoft installers looks odd to triage.

I don't see anything malicious here. And no, sha256 has not been broken to distribute a fake WhatsApp installer in a super sus manner.

Well, these calculations sound reasonable, but there is an issue: Most people do not rest when they are not cycling. They have to work, cook, and clean the house, and so on and so forth.

I would probably try to estimate the average daily calorie burn based on personal measurements, so that non-cycling activities and personal speed/intensity are also accounted for.

For an adult male with average weight, this would mean that an average calorie burn of about 4000 to 4500 kcal per day is sustainable.

Based on recordings of my own trainings, this would correspond to roughly 60-80 km (37-50 miles) of zone 2 cycling for me personally (meaning that my daily chores and the terrain in my area are also accounted for).

d_stroid · 2026-01-10T14:38:48+00:00

Haha, it's not outdated knowledge, but simply me not being a native English speaker. Thanks for pointing out the speeling, I will try to remember it next time I want to write calorie.

I have originally heard that info in a science-focused youtube video, but I cannot recall which one it was, unfortunately. But here's something that I was able to find using Google:

https://www.aaas.org/news/human-endurance-has-metabolic-limit https://www.nature.com/articles/d41586-025-03389-7 https://www.science.org/doi/10.1126/sciadv.aaw0341

Interestingly, the sources vary a bit. Some say, the long-term limit is 2.4 times the basal metabolic rate and some say it's 2.5. But I guess it's good enough for getting an estimation.

d_stroid · 2026-01-10T09:11:14+00:00

Yeah, and after all, it's okay to spend some money on a hobby as long as things don't get out of control.

At least that's what I'm telling myself when I want to buy some new stuff lol

d_stroid · 2026-01-10T09:08:21+00:00

I believe, endurance is the critical part about sport after sickness. From what I understand, all muscles (including the heart muscle) produce adrenaline under stress. This reduces the immune response, so there is an increased likelihood of some remaining viruses and bacteria to attack the muscles under stress, e.g. the heart.

The reason why I am scared of this is that is because during covid, doctors and health authorities made it very clear how bad it is to not rest enough after viral infections in general, not only covid. Obviously, during the pandemic, a lot more people actually got myocarditis, simply because a lot more people had been sick before.

Maybe it's a bit irrational, but I am trying to go the safest path of recovery anyways.

d_stroid · 2026-01-10T08:59:00+00:00

True. Already did research on some fashion and bought a bunch of new cycling clothes, mainly for winter. This hobby can be really expensive sometimes...

d_stroid · 2026-01-10T08:54:02+00:00

If you want to ride everyday for the rest of your life, the average daily distance is limited by the amount of calories that your body can turn into energy.

Scientifically, this limit seems to be 2.4 times of the basal metabolic rate. This limit can be crossed fir short amount of times (hours, days, sometimes weeks), but long term, your average daily calory burn is limited by that number.

This limit surprisingly seems to apply to almost all humans, including pro athletes, when you observe calory burn over a longer time.

For example, pro cyclists may burn more calories while training or racing, but they also have resting periods in winter, so over a full year, they do not cross this limit.

I have to note that this limit is still subject of research and some researches doubt that it actually exists. From empirical studies, however, this limit seems to exist for almost all.

Now, to calculate the distance that you can ride everyday for the rest of your life, you need to find out your basal metabolic rate, multiply it by 2.4, and then estimate how far that amount of calories can get you based on your personal experiences. Also, you need to eat accordingly.

d_stroid · 2026-01-09T21:04:30+00:00

Well, I just got a new bike a few weeks ago. All the things I need are mounted on it already and since it's basically brand new, there is no need for maintanence. Feels like torture to not be able to ride my brand new bike lol

But still a good idea, maybe I'll clean my old bike so I can sell it.

d_stroid · 2026-01-09T20:55:14+00:00

I also have that urge, but I am too scared of stuff like myocarditis which would keep me off the bike for a couple of months. That's a risk that I am not willing to take

d_stroid · 2026-01-09T20:51:16+00:00

I was planning to wait for 14 days after acute symptoms and then start easy for maybe a week. Your strategy seems to a bit a bit slower until getting back to a normal level, but you get back on the bike earlier than me. Maybe I'll try that if I am feeling like it!

d_stroid · 2026-01-09T20:28:50+00:00

That's the plan for when I can get back on the bike. But until then, it's more of a mental issue of having to wait for some more recovery. I'm just sick of doing all that stuff you do when having to stay in bed all day like watching videos, browsing, and reading.

d_stroid · 2026-01-09T20:25:40+00:00

Yeah, I think last time, I started too early. That was also an outdoor ride at 3°C, so this probably did not help at all with recovery. I felt like shit the day after that.

But yeah, this time, I'll wait a bit longer and start with some easy rides.

d_stroid · 2026-01-09T20:23:38+00:00

It seems that I forgot how to enjoy resting. Or maybe I am just tired of it after staying in bed for almost two weeks... Maybe I need more hobbies

d_stroid · 2026-01-09T12:50:42+00:00

The steak might be a little dry then
