It depends. On a hard disk drive - it probably can't be recovered (without specialist equipment and depending how many times you overwrote the file). On flash storage or SSD, there's no guarantee that your dd command actually overwrote the blocks that originally stored your file, they're merely marked as "free" space. So potentially the original file could be recovered by an adversary with enough interest in recovering what you've deleted.
The only way to guarantee file deletion on flash storage is to erase the entire device using something like DD. Or encrypt the filesystem, then delete the decryption key. (provided you didn't store the decryption key on the same device "for convenience")
I suspect what might be happening is a programming logic bug:
1: Photo synced from local device to cloud storage
2: User deletes photo
3: Photos app database marks photo as deleted
4: Photo deleted from local storage
5: Database entry for that photo is removed
6: Command to delete photo from cloud storage fails
7: Command to delete from cloud storage is never checked for success, and so is never re-tried
When update is done, the photos app reconciles the images on the device on the phone and in the cloud to what it knows in the database. Any additional files that aren't in the database are re-added - hence old "deleted" photos reappearing.
Do El Reg not use sub-editors any more, or is that delegated to AI? Spot the glaring mistake in the sub headline:
You can fit more than 50 Virgin Bro pixels into a single iPhone one while angular resolution remains a little low
That should be Vision Pro of course! I've no idea what Virgin Bro pixels are!
I had the same. I worked for a local radio station at the time, and as there was no BBC station in the area, we were part of the emergency broadcast network. As I was the on call engineer, my phone was placed on the priority register.
For several years after 2000 until I changed my provider, I never ever had any problems phoning or texting anyone - never got a network busy notification :)
The mobile base sites treat emergency calls the same way - if the local cell can't service an emergency call, it will drop one of its in-progress calls to allow it to process the emergency call.
That's simply not true. I drive a BEV, I can't charge at home, can only charge on public superchargers and fast chargers. Over the last 2 years of running a BEV (because I've an app that tracks all the data), it's costing me 9 pence per mile, with an average price of 32p/kWh. If I could charge at home, the cost per mile would be less as I'd be able to switch to an EV specific electricity tariff to give me cheap overnight electricity for charging.
Your Tesla prices are a little out of date. If you're a Tesla owner (or pay the subscription to Telsa to be able to charge your non-Tesla car at the Tesla chargers that are open to all), it's actually around 35p off-peak, and 43p peak per kWh. (Peak times vary at different superchargers but usually it's similar to 4pm to 8pm).
I've had a Tesla for over 2 years now, I can't charge at home, but using superchargers, free charging at supermarkets etc, over the last 2 years my cost per mile has been 9.1p - so around half the cost of running a petrol car that averages 40mpg. Not to mention cheaper servicing costs.
As in towns and cities postcodes only cover around 15 houses on average (or 1 block of flats), they are usually very small geographic areas - so it's not surprising the satnav seems uncannily accurate. On a long street there'll be multiple postcodes covering only few of the houses on either side of the road.
There are also 55,540 postcodes in England and Wales that cover a single household according to the Census 2021 website.
Wow, that can escalate quickly. If that means what I read it to mean, by adding outsourcers...
So if I outsource my telephone call handling to a third party call centre, I have to pay a fee for every single employee of that call centre, not just the ones handling my phone calls?
It's highly ambiguous. The last bit of the sentence reads "that support your internal business operations" - how do you define that. Dropping the list of employment types, the line reads all of the full-time employees, part-time employees and temporary employees that support Your internal business operations.
So is that all staff of the companies that support your internal operations, or just those third party employees directly involved in supporting your internal business operations?
The mobile network shouldn't get locked up. the GSM specification means that emergency calls are specifically flagged in the communications between the mobile and the base station, and if the base station is busy, it must drop an active call to allow it to service the emergency call.
So in theory, emergency calls from mobiles will always be able to be made.
Also, around the turn of the millennium, because I was working for a radio station deemed critical infrastructure, my mobile was put on the system as a high priority device - after all, if it all went wrong on NYE 2000, they needed to get hold of me to go into the station. Oddly enough, for several years until my number was removed from that list, I never had any problems phoning friends/relatives or texting around midnight every new years eve!
Ah, but even on commission, if you're an employee you're entitled to minimum hourly wage. This has already been tested in the courts over waiters/waitresses and tips, if the tips don't come up to minimum wage, the employer has to make up the difference to pay the employee minimum wage.
The GSM spec has always implemented this. Because I was working for a broadcaster considered vital infrastructure in 1999/2000, for the period over the millennuim my phone was added to the system as having priority - if I needed to make a call and the local cell had no spare channels, it would drop an existing call to service mine. (The network is also configured to drop any active calls as necessary for anyone trying to make a 999 call so that the closest cell with the best signal will service the 999 call).
You're forgetting one vital part of these conferencing systems - they ALL have to be able to be decrypted by the servers of the company if you want to be able to use features like the ability to join the conference by telephone.
If the supplier can't decrypt the streams on their servers, how do they get at the audio to send it to the telephone participant, and how do they inject the telephone participant's audio into the conference?
Actually, the majority of HV transmission lines are also AC, and depending on need could be running at anything from 1,000VAC up to 800,000VAC. (Due to the nature of AC, the higher the voltage, the lower the current required for transmission, and therefore the further it can be transported with minimal losses - the losses are caused by resistance, so the less current flowing, the less the resistance affects the transmission)
The benefit would be more akin to allowing the AI to decide what goes forward to a human radiologist.
I.e. If the AI is 90% certain that an image is cancer, then a follow-up is automatically scheduled, no radiologist needed.
If the AI is almost certain the scan is cancer free, then no action taken.
If the AI probability of cancer falls within a certain range, then the scans are flagged for a radiologist second option.
This would reduce workload on radiologists to those cases where a trained eye and patient history (including familial history of cancer) is needed.
It was the air feed into the cockpit that used to be fed from one engine, and in the newer model was switched to be fed from the other engine.
The pilots observed or smelled smoke coming in via the cockpit ventilation system, and shut down the engine they believed to be feeding the cockpit, not realising Boeing had changed the design and the cockpit was now fed from the other engine to the older model.
Actually, the Eiffel Tower is not copyrighted. You can take photos of it during daytime and exploit that photo for monetary gain if you like.
Where French copyright law will hit you though is if you take a photo of the Eiffel Tower at night - the lighting is a more recent art installation, and is covered by French copyright. Therefore while you can photograph it for personal use, you may not exploit that photograph commercially without permission.
"I'm not an expert, but if you can do exactly that in the Windows hosts file, I doubt it can be any more of an issue for an ISP with trained professionals."
You can't just block an IP address - the way many modern sites are hosted now, if you block one IP address, you could also block many innocent sites that are hosted on the same server.
