I suspect that you need to think of the 3 B->E voltages as inputs (OR'd with each other) and the C->lowestvoltageE path as the output. All of them are operating in linear mode too, I think one of them is a low-gain follower whilst others have a lot more gain. Maybe.

~~Nope, bottom right and top middle >:D~~

Oh my god I've forgotten what a base is. This transistor is doing my head in.

I don't want my children influenced by this. "Dad why does your transistor only have 3 legs?". And I had only just rid the house of dual-gate mosfets too!

I only know what wikipedia tells me about these things, I've never played with one. I also have no clue yet what it does in this circuit.

3 emitters and 2 collectors.

There are some youtube videos of people machining them (sadly my browser does not support smell). Looks like you treat it like any other solid material: hobb or mill the teeth. This is much more expensive than 3d printing.

You might be surprised by your 3d printed gears. If you keep the detail size large they work really well, but backlash is definitely an issue.

I happily ran THUGPRO under wine, so I assume rethawed would be the same. Dunno.

Where am I even supposed to buy it if I wanted to, which I don’t really,

Looks like it's abandonware. Yeah, publisher dropped the ball.

Changing virtual desktops works for me, no patches needed. I have to use it often because of how many games don't understand multiple monitors.

Technically they have some differences, but the biggest from a user's perspective is how they are delivered and by whom. Wine is manually installed by you from your distro's package repo. Proton is provided by steam when you install a windows game on a Linux steam instance. If one breaks then you complain to the relevant party.

Might be worth checking out ReThawed.. You can choose the physics models, UI, characters, tricks and maps from all of the old THPS games.

I tried THUGPRO previously (another community mod in similar vein) and it was fun, especially the mods to the park editor (overlapping objects!) and Sonic Adventure maps.

If you end up buying some flux then I'd recommend you also buy and try a block of violinist rosin:

https://www.ebay.com.au/itm/315948528490

You break it up and then dab chunks onto your joint whilst soldering. Some will melt off and then burn. From there it acts just like any flux: reduces the metal oxides, makes the solder suddenly flow (behave) a lot better and provides some level of temporary oxygen shielding with its off-gassing products.

Pros:

  • Cheap
  • Doesn't smell awful
  • Long working time (easy to use)
  • Very simple ingredient (distilled pine tree sap) made by many manufacturers, so it will never go out of stock.
  • Residues are non-conductive and can be safely left on your boards
  • Residues are reasonably easy to clean (isopropyl & most board cleaners work; ethanol also works but tends to leave ugly white streaks)

Cons:

  • Smoke is still harmful (smoke = incomplete combustion compounds)
  • Residue is dark, unlike the transparent residue of many no-clean fluxes, so it can hamper inspectability for mass manufacture.
  • Best handled with tweezers, otherwise your fingers end up feeling sticky (pine resin compounds are slightly sticky)
  • Not Modern or youtube popular, so people will tell you that it's therefore bad or worse than other products.

I use it often, it's my favourite for both big joints and fixing smd work. Grab some and try it :) The worst you will be out of pocket is a few dollars.

I've had some issues with other flux products I've used because of their alcohol content boiling off & cooling my board whilst I'm trying to heat a region up to work on it. Solid rosin doesn't have that problem, you can dab it on whilst the iron is still covering some SMD joints (eg QFP pins) on your board and it will work instantly.

Ooh thankyou for the link.

“We can leverage it [ray tracing] for things we haven’t been able to do in the past, which is giving accurate hit detection”

“So when you fire your weapon, the [hit] detection would be able to tell if you’re hitting a pixel that is leather sitting next to a pixel that is metal”

“Before ray tracing, we couldn’t distinguish between two pixels very easily, and we would pick one or the other because the materials were too complex. Ray tracing can do this on a per-pixel basis and showcase if you’re hitting metal or even something that’s fur. It makes the game more immersive, and you get that direct feedback as the player.”

It sounds like they're assigning materials based off the pixels of a texture map, rather than each mesh in a model being a different material. ie you paint materials onto a character rather than selecting chunks of the character and assigning them.

I suspect this either won't be noticeable at all to players or it will be a very minor improvement (at best). It's not something worth going for in exchange for losing compatibility with other GPUs. It will require a different work pipeline for the 3D modellers (they have to paint materials on now rather than assign them per-mesh), but that's neither here nor there, it might be easier for them or it might be hell-awful depending on the tooling.

This particular sentence upsets me:

Before ray tracing, we couldn’t distinguish between two pixels very easily

Uhuh. You're not selling me on your game company.

"Before" ray tracing, the technology that has been around for decades. That you could do on a CPU or GPU for this very material-sensing task without the players noticing for around 20 years. Interpolate UVs across the colliding triangle and sample a texture.

I suspect the "more immersion" and "direct feedback" are veils over the real reasoning:

During NVIDIA's big GeForce RTX 50 Series reveal, we learned that id has been working closely with the GeForce team on the game for several years (source)

With such a strong emphasis on RT and DLSS, it remains to be seen how these games will perform for AMD Radeon users

No-one sane implements Nvidia or AMD (or anyone else) exclusive libraries into their games unless they're paid to do it. A game dev that cares about its players will make their game run well on all brands and flavours of graphics card.

At the end of the day this hurts consumers. If your games work on all GPU brands competitively then you have more choice and card companies are better motivated to compete. Whatever amount of money Nvidia is paying the gamedevs to do this must be smaller than what they earn back from consumers buying more of their product instead of competitors.

really flashy guns and there is a very intricate damage system that runs at least partially on the GPU.

Short opinion: no, CPU's can do that fine (possibly better) and it's a tiny corner of game logic.

Long opinion: Intersecting projectile paths with geometry will not gain advantages being moved from CPU to GPU unless you're dealing with a ridiculous amount of projectiles every single frame. In most games this is less than 1% of CPU time and moving it to the GPU will probably reduce overall performance due to the latency costs (...but a lot of modern engines already have awful frame latency, so it might fit right in fine).

You would only do this if you have been told by higher ups that you have to OR if you have a really unusual and new game design (thousands of new projectile paths every frame? ie hundreds of thousands of bullets per second). Even detailed multi-layer enemy models with vital components is just a few extra traces, using a GPU to calc that would make the job harder for the engine dev for no gain.

Fun answer: checkout CNlohr's noeuclid. Sadly no windows build (I tried cross compiling but ended up in dependency hell), but still compiles and runs under Linux. Physics are on the GPU and world geometry is very non-traditional. https://github.com/cnlohr/noeuclid

 

I could not find any mentions of these problems online. The article itself has no technical detail.

Looking forward to seeing what the actual problems are. It seems this is the first product to market.

Guesses based off the general subject matter:

  • Silica concentrations probably vary depending on the exact position of your head, especially since it's heavy material. If you mount this sensor even a few meters away from a worker then it's readings could possibly become invalid, eg because an angle grinder is firing dust a different direction to the sensor.
  • Silica is a slang term for a very big category of materials. Some might look completely different to others under certain laser observations, leading to some getting missed (bad) and others materials triggering false positives (leading to the sensor's screams being ignored by workers).
  • Self-cleaning routines might be needed to stop it clogging up, otherwise the sensor starts reporting a higher baseline. They could either choose to report this ("pls clean me" light comes on) or ignore it (bury head in sand mode).
  • Alternatively it's performance might actually be fine, but perhaps it's still being spruked inappropriately. Government involvement in funding the project might (?) magnify this problem.

I'll make an account through Slrpnk if this doesn't work.

“And then we’re going to add this suspension into some hexane. I mean here I’m just using Shellite because it’s from Bunnings and I dunno who else uses this so I feel like if I stop buying it Bunnings will stop selling it so, it’s like a couple of bucks and it’s like hexanes, it’s so good, Bunnings keep selling this please”

 

Key excerpt:

According to the late professor Patrick Troy, here's how things were viewed in the early 1970s:

"The cost and price of housing continued to be a source of social and political concern. Over the period 1969-1973 the number of years' average earnings required to buy a house site increased substantially. In Sydney, it increased from 1.7 to 2.7 years, while in Melbourne it grew from 1.2 to 1.8 years."

Compare that to what modern researchers have to say about Australia in 2023:

"Since 2001, the national ratio of median house price to median income has almost doubled to 8.5, and the time required for the accumulation of a deposit for a typical property has increased from six years median earnings in 1994 to 14 years currently."

 

The real reason we warn kids to stay away from the tracks. It turns out that confectionery is cheaper than gravel in some parts of the world (and resists water erosion better because of the wrappers). Sadly they didn't anticipate anthropomorphic erosion events such as this leading to extended rail line outages.

Once the secret was out it became a nation-wide phenomena for kids to raid the tracks.

Railway engineers have been attempting to address this problem by tweaking the infill composition. A recent experiment involved infilling with only licorice, however it turns out some kids still like it. Local newspapers claim the railway engineers were quite confused by this result.

On the right the girl's hairdo reveals she had a recent near-miss at one of these railway digs. The adults now keep an eye on things -- if you pay close attention you will notice that there is actually an adult (or at least teenager) in this scene. Analyse the image closely and you might spot it.

An aspiring railway engineer at the top of the sketch, wearing blue, is pointing out a flawed sleeper. Either that or he's making a fat joke about one of his friends sitting on it.

The dirt desire-paths around the tracks show that locals regularly walk this line. Maybe it's safer than you think? These kids might not have been the first to raid this spot (how did they lift the sleepers?), I suspect the adults cracked it open sometime last night. Usually rail workers cover these sites with a tarp and signposts within a day of reporting.

Just some kids enjoying the outdoors. Someone must have split a pinata. One of the human kids is helping his aquatic friends get some of the chocolates.

Kids are kids and there's enough chocolate to share. It's the parents you've got to be worried about. "Hanging out with warmbloods again Rexy?" "No he can't visit later! We're going. Now.".

I guess the true power of childhood is not fearing new people. A 5yo family member of mine once got lost in the park, it turns out she had joined a random birthday party (and no-one had blinked an eyelid).

The drawn car is nothing like an Austin 1800 (but possible some other Austin model instead)

Not sure if this is something the community here has interest in.

A section of the creek bank has fallen away, revealing that all of the soil has been recently deposited (~ last few decades). The garbage inclusion likely spreads for dozens or maybe hundreds of cubic meters of earth. We don't want to disturb the soil to clean this out so we're limited to surface level cleaning.

On the flipside: it's lots of deep fertile topsoil. The fast growing weeds, like lantana, absolutely love it.

 

Nothing yet to suggest people should be too worried, "nuclear isotopes" is extremely vague (it could be a harmless quantity and/or low activity isotope). Albeit evacuating the neighbours sounds interesting.

Hopefully not someone who has imported 3 tonnes of health bracelets.

I enjoyed this review (and that of Kings Quest 1) thoroughly. I am very glad I did not try to play it myself, The Scam Bridge would have destroyed me.

I now feel some questions about a few other games that I've played before are answered -- they copied some of Kings Quest's style and feel. Vague memories of a Trogdor game are now haunting me.
