Some insight into the change year-on-year to the South Australian negative pricing; the change may be due to more active management by AEMO (Australian Energy Market Operator). Wind is now mostly curtailed at ~1.2GW and a minimum quantity of synchronised gas generators operating. This was in response to a system security scare in 2016 where the entire state experienced a 'Black System' event where we lost all power -- lights out in the entire state. That was caused by a storm taking out some primary transmission lines on top of a less-than-ideal market generation mix causing a chain of events but it put focus and revealed the bigger security issue everyone ignored -- higher risk figures were reported but nobody cared until it was a problem.
Whilst we have enough wind and solar to take the state to 100% renewable (at times) it is not secure enough to provide industrial contracts or services like FCAS (Frequency Control Ancillary Service). With dwindling industrial contracts for energy providers the generation market has gotten smaller, primarily supplying domestic load/customers. That on top of a privatised market lacking responsibility for planning ahead has left the local market in a flux. The spot market has become so unreliable that some businesses have opted for their own on-site diesel generation.
One may assume that this would mean our power prices are pretty low. But that isn't the case. It has been said we have some of the highest electricity prices in the world. In context, this has been because of waining industrial load contracts and profit focussed privatised generators. We just also happen to have a high-wind generator mix.
So whilst living in a state with a high % of renewables is great, the lack of planning in a privatised market has left everything a bit messed up. Businesses looking outside the highly variable spot market into the hands of fossil fuel generators, domestic customers paying some of the highest power prices in the world, and nobody is really responsible/accountable for keeping the lights on.
The vulnerability may still be present in the allowed timeframe. This could just lead the investigators to carry around portable cracking devices to use at the earliest moment they can. A kind of technology arms race?
This might come across as a bit 'gushy' but it really has had a massive impact on what I am working on and what it enables us to do.
I've been evaluating WYSIWYG editors to use in one of our main products for about a year now. I stopped looking when I saw CK5 back in Alpha 1.
It ticked all of the boxes: modern build architecture, easily extensible, diffs/deltas/transform-ops at the core for collaborative services -- it's made for today and the future. And so much more than that. Where CK4 was great for what is now legacy browsers, CK5 is completely fresh and new for current & future browsers.
I highly recommend checking it out and to absolutely consider using it in a project that needs any form of rich text editing.
Around 2011+ we saw not only quiz apps but also offerings such as "See who views your profile" that would result in an OAuth authorisation. How long were those authorisations active before being revoked? How much data was exfiltrated, then and since, and to whom?
If it wasn't for recent changes to authorisations being suspended after a period of time these tokens could be seemingly worth something to the right person.
The root problem being, average users don't know what they're giving access to and know why its important to be critical of such access.
They were prepared for it to RUD right there on the pad, losing one booster is pretty much one away from a flawless mission. I've been on previous live streams when an anomaly occurs, this was no different and what I come to expect — the moment they didn't cut back to a video feed it was very obvious what had happened and that they'd need time to figure it out.
Doubt any thought of 'Public Relations' went through the minds of any of the presenting engineers. Clearing the launch tower was a massive achievement, everything else was a bonus. Loved seeing the engineers all beaming at the end with John joining in — away from a desk!
I went to a talk by Prof Geraldine Thomas, of the Chernobyl Tissue Bank and Imperial College London, sharing her insights and research into radiation and its effects on the body. The key takeaway from the talk is to take into account the type of release, what radionuclides were exposed to the public and their half-life, and then what the passage of that particular element is through the body to determine what damage can be done.
A notable example is of Iodine-131 causing of thyroid lesions and cancers in the direct aftermath of an event because of its short half life of alpha decay directly into tissue that bioaccumulates Iodine, keeping the alpha decay focussed on a very specific tissue. Other heavier elements tend to (I am not a biologist or nuclear scientist, paraphrasing from a talk a couple years ago) can leave the body without being bioaccumulated, having only released 'tolerable' amounts of alpha decay into a broad area of tissue.
It would be interesting to know if those "unusual cancers" were in some part a result of radionuclide exposure from Chernobyl or the result of other factors. But I — a nobody with a causal subject matter interest — would be hesitant to suggest that there was causation in absence of a hypothesis based on biology tied to the known Chernobyl emissions. Either way, we can find out more about radiations effect on biology if a study takes place — or if there is already one out there?
the reports you're referring to are very docile to say the least.
"Otherwise, the team of international experts found no evidence for any increases in the incidence of leukemia and cancer among affected residents."
Except that according to official numbers Belarus, which after the explosion was right down the wind from it, has overall 1.5 times higher cancer rates than Russia or Ukraine have (Russia and Ukraine have the same rate) with some cancer rates being 2x-3x in the Gomel and Mogilev region - the regions right next to the Chernobyl. Such cancer picture is a new development compare to pre-Chernobyl years.
>It would be interesting to know if those "unusual cancers" were in some part a result of radionuclide exposure from Chernobyl or the result of other factors.
Anybody is welcome to suggest such "other factors" which would explain the overall rate increase after Chernobyl with the distribution of rate so that it clearly increases in the regions closer to Chernobyl, while these factors must also be Belarus specific compare to Russia and Ukraine.
But at the same time, radiation and exposure is more nuanced than when and where an event happened that might coincide with some later generalised health effects. Not all radiation is the same and radiation exposure does not always lead to negative health effects. Cancers occurring in a geo-specific region in correlation to an event don't point to one source.
The radionuclides expelled from Chernobyl are known and traceable, not being found in nature they can be detected easily. Knowing their decay chain over time and, later, the bioaccumulation of those isotopes (based on how people will come in to contact with them) you can start to figure out how tissues that bioaccumulate or come into contact with an alpha source could react.
What I am saying is, it's important to understand that its not just about 'radiation' may equal 'cancers'. We know how to understand this deeper than that, on how to measure and calculate health effects based on the specific isotopes and their related exposures on tissues, primarily internally — because alpha decay has the highest energy but is easily absorbed by paper or the outer epidermis, to do damage it has to be in close proximity to sensitive tissues. So its important to stick to those more calculable and verifiable hypothesis rather than broad 'radiation' and 'cancer' labels.
The Belarus officials like to play with the numbers to get money from different foreign organizations. I'm not saying there are no health implication from radiation fallout in these regions but x2 sounds like statistics are used to drive someone's agenda. Instead if blaming drinking and smoking (and trying to solve the societal ailments that are causing that) they blame radiation, because it brings them money.
you can google it yourself. NCBI has a bunch of works on Belarus situation. If anything, real situation coming from people sounds even more gloom than official numbers.
I specifically mentioned Russia and Ukraine because such factors like drinking, smoking, food, genetics, lifestyle/habbits are very similar across all 3 countries and thus can't explain those post-Chernobyl appeared high cancer rates in Belarus.
The Russian diet also played a huge part. Bioaccumulation of iodine depends on how much iodine is in your diet previously. That's why the Japanese (fish-eaters with lots of iodine) shrug off radioactive iodine while Russians (bread-eaters) readily absorb and are damaged by it. If you are worried about a recent nuclear incident, a meal of imported cod is a good defense.
> Lights for taxiway C were also on and set to default settings that included centerline lights (green) along its length. Default settings also included edge lights (blue) and centerline lights (green) illuminating the transition or stub taxiways from the runway to the taxiway.
> Runway and approach lighting for runway 28R were on and set to default settings, which included a 2,400-foot approach lighting system, a precision approach path indicator, touchdown zone lights (white), runway centerline lights (white at the approach end), runway threshold lights (green), and runway edge lights (white at the approach end).
Taxiway: centre green along length, blue edge lights. Can have planes on it.
Runway: centre white along length and edges (also landing zone), perpendicular green at end thresholds. Should not have planes on it.
The planes on the taxiway have white takeoff/landing lights. It sounds like the second in the queue didn't turn theirs on until just before the incident, but if any of the others had theirs on prior, it could contribute to misidentifying the taxiway. I think it's common to have the lights on while taxiing and turning them off at rest.

Absolutely. After 3 months of using it I have only withdrawn cash from an ATM twice.
It's slightly amusing to watch the cashier have a moment of confusion as I ask to 'pay by card' then proceed to do nothing whilst I wait for them to get the EFTPOS terminal ready. They expect some kind of shuffling to produce a card instead I extend my wrist out to pay with an Apple Watch.
Can't wait to see what numbers come out from this, interested to know % of Apple Pay transactions on activated cards.
