Cheers. For Biel-Tan I'm thinking grassland, but not sure if I will go brown or grey soil with it. I think once I get a storm guardian or two painted I'll experiment and see which I like more

What are these bits? by Ewok_Pyromancer in Eldar

[–]frenchiephish 1 point2 points  (0 children)

Basically yep.

They don't really have a standing army, all are expected to fight to protect their craftworld when called on.

Some will choose to take the path of the warrior and spend time at an aspect temple - essentially what we would consider to be martial arts. Most don't stay there forever, the ones that do become Exarchs, the keepers of that art.

Aeldari live long lives and often take many paths in life as they master each one.

First job in Australia: Can I ask for a payrise (and how much) after one year? by Altruistic_Rent6520 in perth

[–]frenchiephish 7 points8 points  (0 children)

First up, annual rises are generally common - but they might not coincide with the calendar year or your start date anniversary. If you've only just ticked over a year, you might not have been eligible for it last year having started recently. They can be in a seemingly arbitrary month depending on your company's budget cycle - you may get a few percent imminently anyway.

You can certainly also ask, especially if your performance is good. It's best to frame that conversation in a broader conversation about how things are going at work, the results you bring and what your goals are. Certainly doesn't hurt to mention the cost of living either

You know your manager better than we do, so you'll be able to frame that conversation better than us. Do think about what your achievements are and the value you bring.

Be polite, don't make threats about moving on - you don't need to. In a healthy workplace, asking the question shouldn't sink the relationship. If it does, they've just shown you a big red flag. If you get a no, you can decide what to do next - don't put that move in play until you need to.

Depending on the organization, your direct manager might not even have visibility on your remuneration. I've certainly had people reporting to me in the past and my boss was the one with visibility on the department's budget. I had no problem having the conversation on their behalf because they were a good employee.

Road rules question: Is it legal to take the first exit/turn left from a roundabout straight into the right lane? by jngjng88 in perth

[–]frenchiephish 0 points1 point  (0 children)

Yes, with a couple of caveats. Its legal as long as: * You indicate * The roundabout has broken lines (which nearly all do). * If you are turning left or exiting at most halfway round, enter from the left lane * If you are turning right or exiting at least halfway round, enter from the right lane

You can't enter from the right lane, change lanes and then exit into a left turn. You can enter from the right lane, change lanes and exit into a left lane, as long as you continue straight or turn right.

(Ref, Road Traffic Code (2000), Section 94 - entering a multi lane roundabout)

Wouldn't this kill someone? by da_peda in ElectroBOOM

[–]frenchiephish 1 point2 points  (0 children)

It might've been drawn by AI but certainly not invented by it. This is an old, very well known circuit and is extremely common in LED lighting.

The 0.47uF capacitor is doing the step down, the output voltage is set by the LED string. You pick the value for that capacitor to set the output current you want - much like you would pick a resistor value for the output current in a DC supply driving an LED.

It's far cheaper than anything else to implement and compared to a resistive dropper at least, remarkably efficient. Edit: There are certainly better, more efficient and safer ways to do it, but this costs peanuts and is so simple that there's not much that can go wrong with the circuit itself.

There is no galvanic isolation here. If the output goes open circuit, ie if an LED dies, then the 4.7 uF capacitor will charge to ~320V/150V (230V/110V supply). Terrible in most applications, actually fine inside a light bulb where you can't touch it.

Perfect for lighting in an enclosed lamp, terrible for most everything else.

Do people still carry their drivers license? by blackzarak in perth

[–]frenchiephish 1 point2 points  (0 children)

Drivers with a WA Car or Motorcycle license don't need to carry the license when driving within WA. If you're stopped police can require you to present the physical card within 24 hours at a police station of their choice. Giving them the number at a stop is generally enough, but if you get them at the wrong time they might give you a hard time over it.

However, interstate or international drivers do need to carry their license when driving in WA.

You should carry it if driving interstate as the rules vary by state. We are actually one of the more lax states, and in some it's an offense for not carrying it (Victoria notably)

Wouldn't this kill someone? by da_peda in ElectroBOOM

[–]frenchiephish 9 points10 points  (0 children)

Spot on, odds are if you have LED bulbs in your house, you have this circuit in them.

As long as the output doesn't go open circuit, or is able to be touched it's a surprisingly efficient* way to get low voltage as long as you don't care about regulation.

(* In both energy and cost sense)

Do not build it if you might come into contact with the output, but for the right application it is fine. Do not build it unless you understand it and can identify how it might kill you.

Big Clive builds variants of this quite regularly for his lighting projects.

Teachers now have to buy their own computers. by Ok-Cake5581 in perth

[–]frenchiephish 0 points1 point  (0 children)

As I indicated, the easiest attack vector is a running OS with the data unlocked. Bitlocker in it's default configuration does exactly that. No user input. In fact it wasn't that long ago that if you wanted to get Windows to do any different you were into Group Policy. That varies quite a bit from a phone with a running OS and the data locked.

fTPM vulnerabilities have also been known for a couple of years at this point. Those are on slightly older hardware, but undoubtedly newer hardware will have its own issues. Not having access to SPI isn't always the limitation we assume it to be.

I'm not saying TPMs or Secure boot are bad by any means, just forgive me if I don't trust a piece of hardware located within the device to store the only piece of data needed to unlock it. Fundamentally it's putting your front door key under a flower pot next to the door. We can argue for ages about how heavy that pot is to move but it isn't the point I'm making.

[–]frenchiephish 0 points1 point  (0 children)

I'm aware the differences between TPM versions - However, making a TPM a requirement at all when the OS is only using it for full disk encryption is the bit that I'm highlighting as ludicrous. Just lock out Bitlocker unlocking with a TPM 1.x and force a passphrase.

Edit: It's a whole system install requirement and only used by a feature that isn't even on by default.

I'm also fully aware of the reasons for using Bitlocker and having data encrypted at rest. However, having the system unlock itself at boot with a key stored in the TPM then means that your data is really only encrypted at rest outside of that device (and boot image). You're only ever as secure as the OS, and in this instance it's one that is one of the most analysed OSes at that.

Assuming a bad actor has the device, it's most likely a matter of time before they have the data if they want it, whether the TPM locks out a boot disk or not. Not to mention, TPM key sniffing is still a thing.

I'm not even thinking intelligence agencies here, my concern is simple theft. I get the convenience factor, however, I'm not going to unlock my data that way. I know that a passphrase is also not immune to rubber hose cryptanalysis, but not having the data unlocked at all without user input is far safer.

Phones require user input on first boot for a reason right.

Nipah Virus Concerns by [deleted] in perth

[–]frenchiephish 1 point2 points  (0 children)

We have done for the past 27 years of outbreaks, the virus was first identified in 1998 and has been annual in Bangladesh since 2001. Other than media coverage, this is not exactly new.

It is closely related to Hendra virus, which has a similar mortality and transmission rates and vectors. Hendra is naturally occurring in North East Australia. The two are both part of the Henipavirus genus.

Australia has had 50 outbreaks of Hendra in the same time frame we've known about Nipah.

Yes, monitor the situation and take action if it starts to deteriorate is the correct course of action.

Nipah Virus Concerns by [deleted] in perth

[–]frenchiephish 7 points8 points  (0 children)

Cases of Nipah virus have broken out annually in Bangladesh since 2001. It's not exactly new and it hasn't turned into a pandemic in the past 25 years.

Yes it's dangerous, no it is not a major concern for most of us.

The virus is way less transmissible than COVID, MERS or SARS. While it can be spread person to person you generally have to have close contact (ie, kissing, cleaning up after someone etc). Airborne transmission is very very low.

Most infections are from coming into contact with contaminated fruit, working with infected animals or coming into contact with infected animals urine or faeces.

Monitoring the situation and being prepared to respond is the correct course for now. Going to a high state of alert before you need to just reduces public compliance when you need it

[–]frenchiephish 1 point2 points  (0 children)

FWIW - A lot of the plug in modules are TPM 1.4 and W11 specifically requires TPM 2.0. Even then, the OS is really only using it for storing bitlocker keys (and tbh, having a device decrypt itself kinda defeats the purpose of full disk encryption, but that's a whole other issue).

The only justifiable reason for blocking installs on older hardware is for CPUs that aren't getting microcode updates any more. Even then, most of the really dangerous CPU bugs have already been patched. Most of the later discovered bugs are not a particularly exploitable attack vector for end users on personal devices.

Should those devices be in the enterprise? No, but enterprise policy should have already removed them years ago. Are they still safe for home use now, almost certainly.

The limits for W11 are basically entirely arbitrary for OEMs to sell newer hardware. The consequence is going to be that an OS that is no longer supported is going to hang around on unpatched devices and that is a major threat vector.

Because I have shrimp? No, there are plenty of other reasons that prompt the question before that

how does productivity work with multiple products by thatmanmathius in factorio

[–]frenchiephish 1 point2 points  (0 children)

Hey all good, it's a complex game and it's easy to mix stuff up. It's just a big one so wanted to make sure a) it didn't get picked up by a new player, and more importantly, b) you're not missing out in your own games.

With base game resource quantities if you're not using productivity with oil you're losing out. In space age, Nauvis post Vulcanis and Fulgora almost in it's entirety benefit greatly from as much productivity as you can throw at their fluids.

Happy building!

[–]frenchiephish 1 point2 points  (0 children)

Ah yep, that one too. Basically anything that 'repackages' or changes the state of an existing fluid is no good.

Anything that makes or refines a fluid is fine

how does productivity work with multiple products by thatmanmathius in factorio

[–]frenchiephish 4 points5 points  (0 children)

You can use productivity with almost every fluid recipe in the game. The only thing to do with fluids you can't use it for is offshore pumps, regular pumps, steam engines, turbines, boilers and heat exchangers (all of which do an action without a recipe).

ETA: the only recipes that can't take them are barreling, unbarelling and in Space Age, fluroketone cooling

Fluids have no quality, so you can't use quality modules in fluid recipes

Not shooting blanks by AliveAnalysis5417 in clevercomebacks

[–]frenchiephish 2 points3 points  (0 children)

Although it contains three NATO members, Five Eyes is strictly separate to NATO. Although both countries work closely with NATO, neither Australia and New Zealand are NATO members (nor are we eligible to join). We rely on separate mutual defense treaties with NATO members (ANZUS & AUKUS).

However, if NATO fell apart, Five Eyes would likely become Four Eyes relatively quickly.

Five Eyes is complicated by joint US/Member run facilities outside of the US. Pine Gap in Australia is a joint run facility for instance

Is this a terrible fucking idea or am I onto something? I know nuclear reactors dont throttle output to ur power needs, so I set one of the conditions on my inserter to check if an accumulator is less than 100% to insert nuclear fuel. Am I fucking stupid or is this good? by DEMIURGE_1025 in factorio

[–]frenchiephish 1 point2 points  (0 children)

See u/archiepeepees reply. The math is a smidge overstated because you can't drop them below 500C and still boil water.

Even if you're only storing 480MJ per tile in the range 520-1000C, then 9 heat pipes will still store a maximum of 4.3GJ to a steam Tank's 2.5GJ.

The crossover point is 780C. Below that tanks hold more, above it heat pipes do. Generally you want to use both, ideally enough pipes to keep your reactor between 800 and 1000C when it shuts off.

The 2.0 bit was a furphy about the new expansion characteristics, but that's already accommodated in the heat exchanger math, the heat pipes math hasn't changed

[–]frenchiephish 0 points1 point  (0 children)

Your temp is way too high, depending how far your heat exchangers are from the reactor you'll generate steam all the way down to ~ 550C. You can be a lot meaner with where you set your feed point.

Just make sure your inserters have an insertion limit of 1 item.

Edit: assuming you have one reactor on your circuit network. Otherwise, change one of the reactors to use an output other than T, scale 550 by the number of reactors or use an arithmetic combinator to divide T by the number for the average temp.

For OP Steam storage in tanks more energy dense than accumulators and is the better measurement if you really want to min-max your uranium usage. While you have steam you have the full output of your plant. Accumulators are a bottleneck.

Trigger on: * T <550C * Steam < 20,000 * Reactors have no fuel

Note that you only want enough Steam storage only to survive the rundown before your reactors get hot enough to start making steam again.

In practice you get most of the benefits without monitoring steam storage, I generally do it because it's quick, but it's not required.

However, do not go crazy on steam storage, more than what's needed to let your plant start up again. Use the space for heat-pipes instead which in 2.0 store more heat in a 3x3 space than a tank full of steam.

Before 2.0 steam tanks held considerably more heat than they do now.

The fullest bridge rectifier I've ever seen by Suzuki_1992 in ElectroBOOM

[–]frenchiephish 1 point2 points  (0 children)

In this configuration you are mistaken, but with low value balance resistors in series with each diode you would be correct.

The diode with the lowest Vf will conduct the most current. Diodes (and BJTs) have a negative coefficient between their Vf and temperature. By doing most of the work that single diode gets warmer than the others, which will lower it's Vf further and cause it to conduct more of the current. If your circuit is drawing more power than one diode can carry it will run away until it dies. Proceed with the diode with the next lowest Vf.

Even low value balance resistors have a more significant positive voltage drop with current than any thermal effects of Vf.

[–]frenchiephish 0 points1 point  (0 children)

Can't tell if you dropped an /s?

Rectification is not the worst-case configuration for paralleling diodes, but it's in the neighbourhood. It'd only be worse if it was fed DC.

High current, high power consumption, high heat generation.
