If you are wondering why the US government is upset about this, here is a brief list of companies below that have headquartered in Ireland because they are a bit of a tax haven. So I consider this to be a quite astute move by the Irish government to place pressure upon the US government via its corporate overlords.

Apple: Historically used notorious loopholes to lower its effective tax rate to under 2%. Following a landmark European Court of Justice ruling, the company was ordered to pay back $14 billion (€13 billion) in unlawful tax benefits to the Irish state.

Microsoft: Routinely routes astronomical sums through Irish subsidiaries. One of its main Irish entities notoriously posted £220 billion in profit in a single year while paying zero corporate tax via loophole setups.

Google (Alphabet) and Meta (Facebook): Both long utilized complex accounting strategies like the "Double Irish" to transfer intellectual property (IP) and globally generated revenues into the Irish jurisdiction.

Medtronic: A major U.S. medical device firm that legally moved its corporate headquarters to Ireland via a $48 billion tax inversion acquisition.

Allergan: A pharmaceutical giant that executed a similar $66 billion corporate inversion to establish its tax base in Ireland.

Other Tech & Biotech Leaders: Major corporations like Pfizer, Oracle, Dell, Airbnb, and LinkedIn maintain substantial operations and book vast non-U.S. revenues through Ireland.

    poorly planned

    Have you been living under a rock? This messaging about the AusAlert test has been going on for a solid two months, on television, on radio, in printed media, and all over the internet.

    The alert system utilises existing software in nearly every modern smartphone and it is used in plenty of countries around the world.

    Japan uses it for earthquake alerts before the actual earthquake arrives.

    States in the US use it for missing kid alerts - when they've just been noticed missing, right in that critical timeframe where they are easiest to find.

    South Korea uses it for alerting when their North Korean neighbours are getting a bit antsy, and for other, less emergency-ish uses. When I was in South Korea during covid the local government would loudly broadcast daily infection numbers as an emergency alert, so I went into my phone's settings and turned it off

    Of course, the Australian government won't mention how to turn it off because they want people to be aware of these alerts. But for people with hidden phones it's very important information to know, and I dislike that no mention of the ability to silence it has been made in media.

    In Android, it's under Settings -> Safety and Emergency -> Wireless Emergency Alerts. You can turn off numerous sub-categories of emergency alerts in there.

    In iPhone, it's in Settings -> Notifications -> Government Alerts/Enhanced Safety Alerts -> Again, you can turn off any categories you deem irrelevant.

    I actually have been using claude to go through all my old projects and review from a security perspective.

    It flags a heap of things that I never considered, mainly because a lot of my projects were ad-hoc solutions to various issues that were written in a hurry and never intended to be visible to the general internet. But it also has been suggesting architectural and robustness changes that have some value, as a lot of stuff I wrote grew organically and weren't structured particularly well for future growth.

    He's using a "thorn" cuz he's so tistic and awesome.

    The poster's stance is that one day they hope to see thorns in AI generated text.

    This is probably quite difficult to actually happen, as LLMs will see the characters as a spelling mistake compared to their general corpus of text and correct them.

    In the meantime it makes their posts difficult to parse and irritates other readers, so surely this can be considered a win for everyone in the fight against AI. /s

    NASA didn't think the surface of Mars where they landed the rover would be so hard and rocky, basically.

    They need all-purpose wheels that can traverse sand/gravel/bedrock, and to go through sand they need to have a large surface area to distribute the weight and stop it from getting stuck.

    But when you drive over bedrock sprinkled with the occasional bit of gravel, the point contact pressure of the gravel is high enough to break through the parts of the wheel designed to sit on sand, in the same kind of way that you treading on a little bit of Lego hurts, you're putting your whole body weight on a very small object.

    Then you add in the fact that they need to be as light as possible, and also need to withstand -60 to -80 degree C temperatures and a lot of UV (so rubber/nylon/plastic wheels are out) and you end up with the compromise wheel that they have that can be easily damaged.

    "Hey Steve , it's lunch time, we're going out to that hot wings place, wanna come?"

    "Sure let me just set this job up.... ok. Let's get out of here!"

    1.5 hours later....

    "Right , I'll just check and see where it's up t... oh no. Nonononononono. Nononononononononononoonono!"

    Bring back the CES.

    Privatisation of a service that is a hard requirement for the dole means that there is no need for those providers to provide quality outcomes for the people forced to use their services.

    Edit: oh, there are "requirements" in place for these companies to get their money. This just means that it's an endless game of effort minimalisation for employment companies so they can extract maximum profit (See also: the current Aged Care debacle). Nationalise the jobs system, let's keep that money in-house for a better outcome.

    I want someone to bring it up in the political sphere just to see what Senator Pauline Hanson says about it.

    If she approves of it, she loses the backing of billionaires, if she disapproves it, she loses the backing of the Aussie Battlers cookers.

    Which one, which one.....

    I subscribe to a bunch of communities and often there is a cross post with the same title and the same URL link across four or five of them at once. This usually results in a screen or two of the same post repeating for me, and I usually just find the one with the most commentary to check out.

    It would be nice just to do that automatically, and shrink to a single line or otherwise "fold in" the other cross posts to the highest commentary post so they don't clog my feed. Maybe a few "related" lines under the body of the post when you go into it, similar to the indication that it's been cross posted.

    Thoughts?

     

    Hi all,

    In an effort to liven up this community, I'll post this project I'm working on.

    I'm building a solar hot water controller for my house. The collector is on the roof of a three-storey building, it is linked to a storage tank on the ground floor. A circulating pump passes water from the tank to the collectors and back again when a temperature sensor on the outlet of the collector registers a warm enough temperature.

    The current controller does not understand that there is 15 metres of copper piping to pump water through and cycles the circulating pump in short bursts, resulting in the hot water at the collector cooling considerably by the time it reaches the tank (even though the pipes are insulated). The goal of my project is to read the sensor and drive the pump in a way to minimise these heat losses. Basically instead of trying to maintain a consistent collector output temp with slow constant pulsed operation of the pump, I'll first try pumping the entire volume of moderately hot water from the top half of the collector in one go back to the tank and then waiting until the temperature rises again.

    I am using an Adafruit PyPortal Titano as the controller, running circuitpython. For I/O I am using a generic ebay PCF8591 board, which provides 4 analog input and a single analog output over an I2C bus. This is inserted into a motherboard that provides pullup resistors for the analog inputs and an optocoupled zero crossing SCR driver + SCR to drive the (thankfully low power) circulating pump. Board design is my own, design is rather critical as mains supply in my country is 240V.

    The original sensors are simple NTC thermistors, one at the bottom of the tank, and one at the top of the collector. I have also added 4 other Dallas 1-wire sensors to measure temperatures at the top of tank, ambient, tank inlet and collector pump inlet which is 1/3rd of the way up the tank. I have a duplicate of the onewire sensors already on the hot water tank using a different adafruit board and circuitpython. Their readings are currently uploaded to my own IOT server and I can plot the current system's performance, and I intend to do the same thing with this board.

    The current performance is fairly dismal, a very small bump of perhaps 0.5 - 1 deg C in the normally 55 degree C tank temperature around 12pm to 1pm, and this is in Australia in hot spring weather of 28-32 degrees C.(There's some inaccuracy of the tank temperatures, the sensors aren't really bonded to the tank in any meaningful way, so tank temp is probably a little warmer than this. But I'm looking for relative temperature increases anyway)

    Right now , the hardware is all together and functional, and is driving a 13W LED downlight as a test, and I can read the onewire temp sensors, read an analog voltage on the PCF8591 board (which will go to the NTC sensors), and I'm pulsing the pump output proportionally from 0-100 percent drive on a 30 second duty cycle, so that a pump drive function can simply say "run the pump at 70 percent" and you'll get 21 seconds on, 9 seconds off. Duty cycle time is adjustable, so I might lower it a bit to 15 or 10 seconds.

    The next step is to try it on the circulating pump (which is quite an inductive load, even if it is only 20 watts), and start working on an algorithm that reads the sensors and maximises water temperature back to the tank. There are a few safety features that I'll put in there, such as a "fault mode" to drive the pump at a fixed rate if there is a sensor failure, and a "night cool" mode if the hot water tank is severely over temperature to circulate hot water to the collector at night to cool it. There are the usual overtemp/overpressure relief valves in the system already.

    All this is going in a case with a clear hinged cover on the front so I can open it and poke the Titano's touchscreen to do some things.

    Right now I am away from home from work, so my replies might be a bit sporadic, but I'll try to get back to any questions soon-ish.
