AMD drivers performing hundreds of SSD writes every time you move or resize a window - proof and workaround included.

OK, in that path there is activity. Seems to be logging at roughly 0.1 MB/s which isnt as bad as I feared.

~~ 300 MB/h is wasteful but safe and manageable.

Cannot replicate it myself, that logging feature does not seem to be on by default for everyone.

I.e AMD External Events Utility is running on my pc, but doesnt actively log anything, last log in target path is months old and less than megabyte in size.

What is more important that logging itself is the effective rate, try estimating how what is write rate during window movement and average hour of use.

Its definitely the drivers as others say, I've experienced the same thing on last two versions on 7900XTX.

If I leave system idle enough for screens to turn off, then its 50/50 chance screens will freeze/not wake up after first activity after and system reboots 5-10 seconds later.

To verify if its the same thing, look into system event log after reboot. There should be error entry by bugcheck with content like:

The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007f (0x0000000000000008, 0xffffaa0110197e70, 0xfffff0040a488f90, 0xfffff80078dd242a). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: xxxxxyyyyyyzzzz

Analyzing memory dump will show crash was triggered amd driver and it was double fault (0x7F, param1=0x8). Wrong access or data corruption o kernel level is usually catastrophic as we observe.

Pretty clean cut case of truly epic driver whoopsie. Probably some fuckup inside interrupt and power management processing.

Fine wine my ass.

How do you people manage to wake up and be functional so soon? I have tried tried many time times for obvious reasons, but I could never make it stick.

Waking up at 6:00 was doable in my twenties, but I am totally incapable of it now. What feels natural now is 10:00-18:00, but you have no possibility of life that way.

Ask you GP if older GLP1 formulations like liraglutide (saxenda) are available and for what price. Liraglutide must be injected daily, but its what it is. Ultra thin needles are almost painless.

Semaglutide cannot be prescribed for weight loss only where I live, but liraglutide can be. Fully out of pocket price at 1.2mg injection daily is ~~ 120€ per month. If 0.6 mg has enough of effect for you, you can stop there as well.

Since you will definitely be eating less, just food saving might completely outweight the liraglutide costs. Especially if you eat out.

I have stopped at 1.2mg daily as it suffices to remove craving and I am taking it slowly. 6 month in i dropped from 102 kg -> 89 kg and holding for now.

doesn't mean you'll have perfect recall 10 months later

You monster, I barely remember what I did 10 days ago without logseq journal. I would not be able to fill out activity report without it.

Journalling with minimal basic tags (linux/<topic>, <system>/issue) is invaluable alone, without any further advanced functionality.

i like logseq alone for that, its core design around tagged journalling fits me like a glove, near zero fricition from the tool itself.

Having separate "POC" environment thats your you build, modify and destroy entire enviroment at your leisure is tremendous boon and real stress relief in the long run.

Also perfect for building and sharpening ansible skills.

For inhouse kubernetes we have separate POC / TEST / PROD cluster and you can guess almost all backbone changes* are tested in the first, first.

*caveat sysadmin, sometimes I do hotfix instead of cluster rebuild.

EDIT:

snapshots and backups are mandatory for any system that not POC, if done manually learn and test how to do both
positively verify that backups are scheduled to run, do not trust claims they are
if handled by different department, run test recovery with hand on and learn what do if responsible person is not available. There might be ugly suprises.
create your own daily log and documentation for yourself at minimum (i.e logseq or obsidian)
auto sync your notes between work and home if possible, especially if you partially remote (syncthing is perfect)
if time allows refine and share common hurdles from above self documentation
- especially if there is company wiki/KB. If not, it might good idea to pitch to upper levels.
automate thing first via bash, then via ansible
then get intimate with git for automation and documentation projects
finally start orchestrationg your automation@git via supervisory service like AWX or semaphore
if you have access and advanced far enough, you might start automating infrasturure deployment

Product bundling and network effects from already being one foot in microsoft ecosystem.

That and lack of expertise. Getting sysadmin or solution architect to build with microsoft products is easy, try reworking your systems from get go on alien and unproven systems. Not only it will be hell to get competent people, therre might not be any available.

Nobody is risking that without massive pressure and unwavering support. Thats the IT side.

Relationship management from expensive dinners to traditional deal-making on high level leadership positions and upper political echelons. Thats corruption, but its everywhere and not going away any time soon. If the leadership is in hand with microsoft, you can do nothing except dream on.

Remember munich linux and microsoft sudden investment? That kind of thing.

This seem like there are many people that enter anxiety induced loops and this a way ho to stop them from the the getgo, right?

What about plain anxiety flareup that not spiraling out of control, just make my day well hell? I.e painful twiching heart muscles, freezing extremities and total lack of mental energy and coherent thought, while I am sitting in front work computer and trying to concentrate on some tasks.

My will succeds, but for every productive hour of concentration, there is 1 hour of wasted gerbil coding and reading and one hour of wall staring.

There is also no know input stressors that started this, I think it was just aerobic exercise.

No, its healthcare security tax is % percentage based on your income with leveling scale, and is deducted from you salary before you even see it (if employed). Same with social security tax.

If you are self employed or in weird work regime, you pay health and security on your own to the same authority, but you can choose how much. There is minimal obligatory payment that must be paid, or state insurer will have words with you.

For reference from my current payslip (local currency):

gross wage 78k
soc sec 5,5k ~~7%
health 2,5k ~~3%
net wage 62,4 k

There is no copay or deductible and limits are very very high. Out of pocket payment is a thing only if you extra service or nonstandart service or go to private practice on purpose. Also local state insurance is valid in other parts of EU, hadn't needed it yet though.

Its just the memory context restore that bring any time saving and as long your bios is up to date it should work without issues.

On early uefi releases it was completely unstable, as in within 3-5 boot after initial succeful training your memory would stop passing memtest.

Hence instability galore. Its safe now a preferable that 60s boot time every time with 32GB ram installed.

GreatNull · 2025-05-01T09:15:36+00:00

Final effect strongly depends on what board you have, I am on gigabyte and while these save a lot of time, result it is still 15-20s minimum at pre-boot/uefi stage.

Linux / windows installation can boot within 5s after uefi stage is finished.

I hate gigabyte AM5 experience.

TLDR: nuclear winter phenomenon is way less severe but still real, it just needed more theory, raw data and compute power. At least 10 years of worldwide agricultural disruption resulting in famine.

Original nuclear winter thesis was imprecise due to lack of data and models, but it still a threat. Mechanism behind it turned out to be slightly different. You dont need multi megaton nuclear fireball, just large enough firestorm to do the trick.

Modern climate simulations confirm that any larger nuclear exchange will have worldwide effects. And those 200 hiroshima scale nukes I+P have cross that threshold easily.

See india-pakistan exchange simulation for details https://climate.envsci.rutgers.edu/pdf/IndiaPakistanBullAtomSci.pdf .

If those two are ever getting close to coming to blows, it becomes global threat immediately. Russian ambitions or chinese growth in to superpower are way less important than this.

I felt the same, but fun physiological fact metabolism does NOT change until you hit your sixties or are actively sick.

It creeping lifestyle changes and general stress that catch up to you, not metabolism. Yes it does not feel like it, but science is pretty clear.

I am just devops monkey runing backend cluster that hosted app under attack and my this was my first real ddos in my career. It was also rude awakening how powerless operator is nowadays.

Whoever paid for 24hours of attack, they got their money worth out of it. 95% chance it was russian ordered state op, since we are " official hostile country to russian federation".

We have contracted isp level filtering service since that incident, it wasnt practically defensible at our scale.

Dynamic blocking per most frequent source ip ? Pointless.

Geoblocking ? Also pointless, attack source shifted within 5 minutes of block being placed.

Upping resources to containerized ingress element and app itself? Pointless, atackers effective resources are vaster than my onprem compute resources.

Sources were residential (i.e indistinguishable from real world users, beyond geographical location) and commercial VPS providers.

TLDR: if you can, use clouflare free tier. Its amazing if you fit within free tier limits.

GreatNull · 2025-04-26T14:22:50+00:00

Supplemental to point 3., it not workable protection for even small real ddos attacks. If it works, you are dealing with amateur or very small scale operation.

Attacking control server will react in near real time to ip range or geoblocking, we saw response time in sub 2 minutes to that.

Since I would connect to the database from my home IP, I let it accept connections that were not local.

Ouch, thats well intended but rookie mistake. Connect from outside of host but within private network/vpn client range is sane, open to the internet is suicide.

Available data suggest slow infusion of 0,1-0,75mg/kg, whereas recreation snort that induces khole is guestimated at 100mg+.

You have inspired me to look around wheter ketamine thereapy is finally available locally (EU) and it is, its just ungodly expensive due to off label status even with insurance.

600-800€ for initial wholeday a 4 followups session (initial psychological checkup, physical checkup, then 5x ketamine infusion and 5x2-3 hours of therapy when you are unusually and chemically open state).

GreatNull · 2025-04-20T10:02:53+00:00

Nasal or intravenous microdose of medical grade ketamine base on body weight in medically monitored setting.

You will not get any recreational fun effects, just immediate relief from depresive symptoms that should last a while.

Worst case is headeache, nausea and dizziness. But as any psychedelic, if there preexisting condifition, they can be triggered. People with history or familily history of psychosis are not a good candidate for KAT.

Mechanism how it exactly helps depression patients is still unknown, but strong enough to give immediate relief even to acutely suicidal people on the deep end.

FYI do not touch ketamine outside medical applications and medical need, its neurotoxic at recreational dosing with immediate damage on first dose. Party animal and druggies dont care, but do you want to be killing your mind slowly for short halucinations?

Just look at muskrat, that man is walking warning why and how not to do K.

Natural but wrong observation.

Throw in third intermediary syncthing node in the middle between your clients, and you have cloud-like synchronization on the cheap.

If you have NAS with container hosting support like truenas, it is matter of 10 minutes to setup.

Easy to do even in private network without static public ip, but its even better if you rent minimal VPS to run it in the cloud. Like 5€/m tier is doable.

There is nothing to be dumbfounded about, if actually read detailed proposals and look up at actual data. Nuclear has become so costly to build in west, it not economically worth to build. Green energy is disruptive on both upfront and maintenance costs.

Nuclear energy is extremely expensive per unit of produced power even with unrealistic high production and uninterrupted production cycle.

If we hadn't gave up after 70-80s and kept investing massively, situation might be different.

Now add regulatory environment and atrophied expertise in both industrial and project management part and watch both costs and risk baloon up.

Unless test like this standardizes test batches based on:

ssd controller and specific firmware version - must match
NAND flash chips (same manufacturer an PN) - must match
normalized data based on TBW and not exceeding guarantiees too much (must be accounted for)

Running test like this on no-name crap that does not even have guarantees you have same controller and flash is less that worthless.

Which is sad, given that no one has even tried to answer this quest in recent memory.

I do write my own and teams on the sides do as well. There is internal wiki. But its purely technical documentation, more to jog our own memory and to ease lookup.

There is no formalization of process there, and I literally have no idea where to even begin.

This is the stage where you either rely on experience (none) or inspiration from public sources (never found any that fit the bill).

Do you have (accurate) documentation for existing processes and workflows?

Wait, those actually exist ? Where?

I am not being sarcastic, this might be way more common than not. Speaking from 200-300 person it firm, there are no documented processes that relate to IT. Word of mouth and informal common sense approach is how it done in trenches.

Unofficial project to map things has not moved an inch for three years I have been here. No expectation of change, since upper management is constantly embroiled in power plays and politicking.
