Deep-dives on how AI changes what a system monitor can actually do. Long reads, real code, no fluff.
Receipt PRO essay · #4 · new The most dangerous bug does not crash. It succeeds. Six real failures from fourteen months of shipping alone: a button that saved nothing, a check that measured nothing, a Store shortcut that opened nothing. All of them ran perfectly. All of them passed every test. Plus the week I let an assistant write more than I read, and one claim in the article that was wrong until I checked it. Read the essay →Stop optimizing the average PC. You don't have one.
Why thresholds and generic profiles fail your specific hardware - and what a local AI that learns your unit actually does. Afterburner, HWiNFO, CCleaner vs statistical process control.

Inside the Learning Center and the Welford accumulator that learns your machine for the life of the install - and survives 90-day data pruning. New in v1.8.0.
Read the deep-dive → PRO · #36,500 lines in one file. The day I admitted that wasn't fine.
PC Workman hit the Microsoft Store, so I finally split the 6,533-line hck_GPT builder into eight modules behind a facade, and wrote two tests to keep it that way. New in v1.8.5.

Behind the game dev scene
I sat on a finished build for three weeks because I was afraid of it
Twenty-nine days from the first commit to a public build, written down while it was still uncomfortable. What the fear actually was, what shipping cost, and the first numbers back.
Read it ->What USS cannot do in Unity UI Toolkit
No gradients, no arcs, no masks, no positional selectors. What breaks, and what to use instead.
The feature that is finished, tested, and impossible to reach
A green test suite proves a function works. It proves nothing about whether anything calls it.
42 save format changes, and not one broken campaign
One step per version, old shapes kept verbatim, and every reconstruction declared rather than hidden.
What an AI accelerator is worth one, two and three years later
Eight generations, launch price against cost per petaflop, and the residual value table.
Scaling Laws is an AI company tycoon built by Marcin Firmuga under HCK Labs. Version 0.4.0 is free for Windows. The game page has the download, and How Scaling Laws works opens the machinery.
Do you need a Copilot+ PC?
Three hardware requirements, six Windows features, and a longer list of things that work exactly the same without it.
Read the guide -> AI PCDoes an NPU actually save battery?
The published comparisons put a laptop chip next to a desktop graphics card. Here is a measurement you can take on your own machine in twenty minutes.
Read the guide -> AI PCNPU, GPU or CPU: which runs your model?
Not the chip you bought. A driver version and an on-demand download decide it, and one driver range has a documented ceiling you can update past.
Read the guide -> AI PCHow much memory does a local model need?
Two multiplications. One tells you whether the model fits, the other the fastest it could possibly answer, before you download anything.
Read the guide -> AI PCTOPS is not a specification
Intel publishes 120, 67 and 48 for the same processor. All three are true, and only one of them decides whether Windows gives you the AI features.
Read the guide -> AI PCIs your NPU doing anything?
Your laptop has a 40 TOPS neural processor and Task Manager shows 0%. Where the activity shows up, what actually uses it, and why zero is usually the correct reading.
Read the guide -> The recordFourteen months, four jobs, and still no job in software
The complete timeline of building a Windows application after work, month by month, with real dates and real numbers. Including the months where nothing worked.
Read the timeline -> ReferenceThe Silent Failure Catalogue
Six classes of code that runs, returns, passes every test and delivers nothing. Symptom, why your suite misses it, a sweep you can run today, and a dated case for each.
Read the catalogue -> UpgradeRAM, SSD, CPU or GPU: what should you upgrade first?
Make the component earn its place on the shopping list. Match storage latency, memory pressure and CPU/GPU headroom to the task that feels slow.
Read the guide -> Crash diagnosisPC restarts while gaming with no blue screen?
Kernel-Power 41 records an unclean shutdown, not its cause. Read BugcheckCode, dumps and the minute before the restart.
Read the guide -> GPU crashScreen goes black and comes back?
nvlddmkm Event 153 and Display 4101 mean Windows reset the NVIDIA driver after a two second GPU hang. Read the pattern, not the event ID.
Read the guide -> Hardware errorsWHEA-Logger warnings in Event Viewer?
Events 17, 19 and 47 are errors your hardware corrected. Event 18 is one it could not. Read the fields, count them, find the part.
Read the guide -> RAM stabilityXMP or EXPO crashes games?
Compare a clean JEDEC baseline with the memory profile, test outside Windows and stop treating a successful boot as proof of stability.
Read the guide -> GamingHigh FPS, but the game still stutters?
Read the frame-time pattern. Separate shader compilation, asset streaming, VRAM pressure, a saturated CPU thread and a background interruption.
Read the guide -> DiagnosisPC slow, but Task Manager looks normal?
Low percentages can hide one full CPU thread, a short stall, storage latency, a hard fault, low clocks or driver interference.
Read the guide -> GPU memoryHow much VRAM do you actually need?
Dedicated versus shared memory, Windows budgets, game texture pools and the real memory cost of a local AI model.
Read the guide -> ProcessesWhat is this process in Task Manager?
A familiar name proves almost nothing. Tell a real Windows process from malware by its path, signature and parent, with a reference table for svchost, RuntimeBroker and COM Surrogate.
Read the guide -> UpgradesWill this CPU work with my motherboard?
The socket matches and the PC still will not boot. The five layers of compatibility, the three traps a spec sheet hides, and the Compatibility Receipt that says "do not install yet" for a reason.
Read the guide -> TemperaturesWhat's a normal CPU temperature?
72°C while gaming is fine. The same 72°C at idle is a warning. Why one threshold for every PC is a myth - with per-workload reference table.

Your old GPU's driver is still in Windows - hidden by Device Manager. How to find and remove ghosts with pnputil, step by step.
Read the guide -> OptimizationHow to speed up a Windows PC without the usual myths
A useful order of work for startup apps, background processes, services, storage, RAM and temperatures.
Read the guide -> ServicesWhich Windows services can you turn off safely?
A conditional list, the 33-service no-touch guard and a reversible way to test every change.
Read the guide -> HealthIs my Windows PC healthy?
Five plain questions that separate a normal busy machine from a real problem, without a benchmark score.
Read the guide -> MemoryWhy is my RAM usage so high?
Read Available memory and hard faults, then reclaim memory without killing the apps you use.
Read the guide -> CoolingWhy are my PC fans so loud?
Most fan noise is a twitchy curve chasing spikes, not real heat. Build a quiet curve that still cools, and cap it where more RPM stops buying degrees.
Read the guide -> PowerCan software tell if your PSU is dying?
An 11.8V reading is not a death sentence. The ATX spec, why sensors lie, the real signs of a failing PSU, and reading a trend with SPC instead of panicking over one number.
Read the guide -> PerformanceWhy does my CPU or GPU clock drop under load?
A clock drop and a warm chip prove nothing on their own. How to read temperature, power and utilisation together to tell thermal throttling from a power limit from a plain bottleneck.
Read the guide -> StorageWhy is my disk at 100%?
Active time measures time, not speed. Read response time, find the process building the queue, then fix the real cause in the right order.
Read the guide -> Drive healthIs my SSD dying?
The SMART and NVMe values that matter, the raw numbers that often mislead, and why a clean report never replaces a backup.
Read the guide -> StartupWhich startup apps can I disable?
Decide by what an entry does, not its brand or impact label. Find hidden locations, make reversible changes and measure the result.
