brute force – Is it safe to implement 15-byte password reset tokens?

I want to know how careful it is to implement a 15-byte password reset token.

If we have 26 letters and 10 digits, 36 possibilities per byte. And we have a 15-byte long token, which means that the total number of possibilities is 36 ^ 15.

Is it possible to use brute force and find a token within a reasonable time? The amount of possibilities here is really great, so I do not understand why other websites implement +32 or +50-byte long tokens.

Can any one explain that and maybe the calculation behind that to know if this is possible?

Suppose we can use brute force at a demand of 15,000 per second

Is it safe to upgrade bitcoind?

Although some versions perform database upgrades, the upgrade is handled by the bitcoind binary file. Updating a node only requires modifying the binary file, whether you have downloaded a pre-built file or compiled it from the source.

If additional changes to the bitcoin data are needed, bitcoind update will perform them at startup.

If you download a preconfigured binary file, make sure that it comes from a reliable source (such as and check the signatures to make sure it's not been falsified.

windows 10 – Is it safe to unplug a flashing USB drive after ejecting it safely?

There is a lot of information about safely disconnecting USB hard drives. However, articles tend to stop where the operating system says it's safe to unplug, or if you're sure nothing is written to the drive, etc.

Relevant implementation:

  • Windows 10 PC or Windows 10 PC
  • External USB hard drive (not a USB key)
  • Click "Eject External USB 3.0"
  • Wait for the notification "Safe To Remove Hardware"

Once the operating system has declared that it is possible to unplug a USB hard drive safely, the LED on the drive will blink about 10 times before the drive stops.

I wonder if the 10 flashes of LED are just a courtesy to indicate which disc has just been ejected.

Things I've checked:

  • google: is it safe to unplug the flashing USB port

I've received a lot of advice on how to unplug USB drives safely, but nothing to do with the USB drive.

  • google: is it safe to unplug the blink + LED usb

Some other items appear, mainly about troubleshooting, but nothing to do with the routine 10 flashes when ejecting.

  • search super user: (usb) (hard drive) (windows-10) eject

This produces 7 results (or 8 if I replace (hard disk) with (external disk)), mainly about problems. Nothing about routine 10 flashes when ejecting.

Are DSLR infrared conversion companies safe? What about DIY infrared conversion?

I did my own conversion on a Nikon D80, including cutting my own rectangular filter into a 77 nm round hoya filter.

I did something a little unusual and I went so far as to remove the infrared filter from the AF sensor module and meters, as well as the CCD itself.

Really, the exchange of pure CCD filters is quite easy.

Pulling the filter on the sensor is a bit complicated.

Removal of the filter on the AF sensor is a nightmare – You have to take a lot All other components out of the camera, as well as several parts glued and spaced a few millimeters of the delicate circuits.

Reattaching autofocus is also quite simple. Basically, three screws adjust the distance and inclination of the sensor support. It's just a bit slow, takes a lot of shows and is rather tricky.

On the other hand, I have an infrared camera that AF perfectly in IR each time.

The meter also seems to work well. I have to dial a bit of exposure compensation, but I do not think I've changed it since. I think that adding visible light filters to the sensor (rather than simply removing the IR filter, as I did) would likely fix the measurement problem.

Really, infrared photography is really one of the nicest things I've done.

This seems to bring some of the art and imagination back to photography. You really have to think and imagine what your shows will look like, because you can not really see them again before you go to a computer, to make whiteness corrections.


I took pictures of the conversion process, including camera internal elements:
Note that the sensor filter is accessible very early in the photoset (_MG_1030.jpg, about 15 images in the format), and that the process usually consists of taking the back of the camera, unscrewing a circuit board, and then unscrewing the sensor. The rest of the set is what needs to be done to reach the AF sensor (ie remove ALL of the camera body.) It seems that the AF sensor is one of the first parts installed during assembly).

I've also destroyed a Sony alpha A-200, although I'm not able to convert it to infrared because the filter is deposited directly on the CCD's protective glass. The images are also on the link above, or here.
I thought to strip the sensor (remove the glass) or try to cover the filter (it was clearly vacuum-deposited on the surface), but I decided that it was not worth it, but I still wanted to try a Nikon camera. . I still have a bag of cerium oxide after experimenting with polishing the glass for the break-in process.

enter the description of the image here

If I understand correctly, the really striking color photos, as in Matt Grum's answer, usually take a filter of 900 nm or more ( a lot post), rather than 720 nm. In addition, the photo above has not undergone any treatment, except for a simple balancing of whites and clicks. The weak blue colors come from the sensor itself.

Anyway, I recently bought a Canon 5D, going from a Canon 30D (the Nikon was an experiment, I decided that I liked Canon's UI much more), so I'm going probably convert the 30d to IR soon because I have a lot Canon lenses, while I have only one lens for the Nikon.

hand luggage – Is it safe to travel with a radio frequency (RF) board packaged in a laptop carry-on?

In addition to a laptop,
I use a Radio Frequency (RF) card to implement a software-defined radio function (virtual e-node B or gNode-B, for example) with a small plug-in omnidirectional antenna.

Would that be a problem when going to an airport when it is packed in carry-on luggage and a laptop?
