This is not true. All PIC programmable elements are reprogrammable. Including the protected portions. It is simply that those cells cannot be rewritten without bulk-erasing the block they are in.

There are MCUs that have Write-Once-Only FLASH, but PICs are not one of them.

Replaying to myself:

apparently a few manufactures have forgotten why there are raised lines, or raised features on a hood.... well shit.... they are for aiming the car.... who'd of thunk.... oh... and by the way.... Fuck you GM.... some of your recent vehicles respect that the hood is a great place to provide visual indications of lane position!

Long time ago I owed a boat..... 1969 Malibu. One of the cool features of that car once I got the hang of it, is that the hood lines told me where the corners of the car were within a few inches. I knew if I was in the center of the lane by comparing the hood creases to the road markers.... easy peasy. Making that connection took all of about 2 hours of driving....

Today.... not so much... I have driven recent high-end cars that lack those old-school hood marks and are fairly hard to keep in lane without checking the left-outside mirror to check the center-line of the road(!)

WTF?!

Tesla seems to get this but a recent GM vehicle I drove had no 'center-line' marker on the hood. I was hunting the whole time of was driving it trying to figure out what hood feature was giving me feedback.... after 20 minutes I gave up... the left rearview was my best marker.... and that sucked.... I had to keep checking a mirror to make sure I was not over the center-line..... fuck you GM....

That word means 'Peace Officer'

The goal is keeping the peace... it is not LAW ENFORCEMENT OFFICER (LEO)

This is where the role of POLICE and many Sheriff departments have gone off the reservation.

Fire departments have only limited roles in fire prevention.... EMTs do not preemptively save lives by throwing people in jail....

We have allowed the tail to wag the dog as far as policing is concerned.

No blood, no fowl. If someone has not called the cops they should not have a role.

By all means at the time someone calls for police let there be hell, fire and brimstone called forth to protect the public and seek the criminals.

Where there is no victim there is no crime..... The state is a victim only when it loses assets or legal claim to assets. Fuck the crimes where the State suffers no loss....

bullshit. They have a desktop class PC computer in the passenger seat. There is no way you can tell me they do not have the tools to detect a loss of connectivity. WiFi, BlueTooth.... RF whatever.... they are in contact.... loss of streams is reportable, and detectable at the moment that loss occurs. No excuses.

You have a good point there. They are called 'Officers' because they are officers of the court. They have the same status as any lawyer or judge in the court system.

A burglar typically does not have backup on hand... The same holds true for a citizen's arrest. Which is why they are almost unheard of.

('shots fired! Shots fired! Officer down!' 911 Rascal Avenue, cross 33rd Street!' ) No other requirement is needed to rain fatal retribution on a 'resisting' suspect, or to give chase to same.

TL: DR: Burglars cannot do this, and citizens attempting arrest have no access to the resources to do this.

Yes sworn officers need to be surveilled AT ALL TIMES while performing their jobs for OUR safety and THEIR safety.

As a gratefully EX (moved on to better tasks) Dir of Ops of a call center I can assure you every inbound and outbound call is recorded and stored in the call flow. This is in part for CYA, and in part for detecting when a client or customer is engaging in fraud. In the beginning of my term, it also helped catch catch Oracle out when they tried to lie about their service levels on a product that had been licensed from them. No one ever answers a call before the inbound 'Betty' announces to all parties, that the call is being recorded for quality and training purposes. Outbound calls also had a greeting announcement from 'Betty' indicating that calls were recorded.
In the Oracle case it was their own call handling system that was used to catch them.

All nice and fine until the horse-riding-archers show up in force to deprive you of your stores and your life. The only reason the Mongols didn't take over Europe is that Genghis Khan failed to produce a suitable heir for the Empire before he died. Even some of the Khans after Genghis managed to make the Norther Europeans sweat blood and tears.

Europeans had no hope of resisting, had the Khans set their sights on invading Europe.

Yes they died from high velocity lead poisoning in some cases.

The original painting is not really about the colors, or the image composition. A print only shows the colors. The original painting has texture. It has depth. Masterful paintings are not flat. They are as much topology as they are composition, color, and texture.

Blowing spit into a chunk of wood and brass tends to shorten it's life. I gave up playing brass as a young kid.... because.... brass, spit, and oil is fuxing gross to have to smell every day.

you are mixing apples and oranges. @20KHz is in PCM(8 bit/16 bit/24 bit/ 32bit or more bit) samples per second....

44.1K samples per second @ 16 bits (stereo std CD stream rate) is 1.4112 MEGA BITS per second.

320K MP3 or other formats is in BITS PER SECOND.... that is a 4.41:1 compression ratio... and I seriously doubt anyone can hear the difference between raw 44.1KHz PCM and 320K bps MP3, or visually without at least a dual-channel 100MHz digital scope in front of them.

It might be possible to hear artifacts in 320Kbps MP3 (or other lossy formats) but only for completely synthetic signals that would have to be specifically designed to show the losses in the compression format.

One problem with this whole study:

Laying hands on a musical instrument and playing it for an hour is as much a kinesthetic experience as an auditory experience.

As others above have noted. It is entirely expected and not particularly difficult for an experienced, professional, instrumentalist to be able to identify an instrument from the combination of sound AND feel. Even if they cannot name it reliably. They know if what they are experiencing is better or worse relative to some internal standard.... probably their own favorite instrument....

Now a can of worms has been opened. Asking a subject who is capable of identifying an instrument maker based on the combination of sound AND feel which instrument they liked the best does not tell you anything about the overall quality of the instrument.

It doesn't tell you how well an instrument behaves as it wears. It does not tell you how well it behaves after it travels. It does not tell you how well it behaves when it is subjected to an unexpected change in ambient temperature, or humidity during a performance. after the strings are replaced, after it is cleaned..... after it is dropped.... or otherwise mechanically stressed....

String instruments are fickle beasts, and have a lot of subtle traits that experienced players can detect, even if they cannot reliably tell you who made the instrument. I am sure if they were asked to tell you in each case if the instrument was made by the same or a different maker, the results would have been much more consistent, and more useful.

Do you realize that USB 3.0 has 3 power profiles... up to 20V, and that the host and slave have a mechanism for negotiating the both the voltage and current requirements up to 100W (20V @ 5A)

I suspect that these phone charging systems will be using the 20V@5A profile to provide 3.7V@25A to the battery.
(DO NOT touch this iDevice during charge! This iDevice will notify you when it is safe to touch it again. [OK] [[CANCEL]])

So it can be charged in 30 seconds, but you cannot touch it for 10 minutes :)

I suppose you could use it to reheat your coffee while it is charging.
