Prison
Computer ‘Glitch’ Blamed for Opening Cell Doors in
Maximum-Security Wing
Florida prison officials say a computer
“glitch” may be to blame for opening all of the doors at a
maximum security wing simultaneously, setting prisoners free and
allowing gang members to pursue a rival with weapons.
But a surveillance video released this
week (see above) suggests that the doors may have been opened
intentionally — either by a staff member or
remotely by someone else inside or outside
the prison who triggered a “group release” button in
the computerized system. The video raises the possibility that some
prisoners knew in advance that the doors were going to open.
It’s the second time in two months
that all of the doors in the wing opened at once, officials say,
raising questions about whether the first incident was a trial-run to
see how long it would take guards to respond.
… Miami-Dade Corrections Director
Tim Ryan acknowledged to the Herald that the circumstances
around the door-release were “suspicious,” and said officials
were investigating whether any staff members were responsible for
opening the doors or if a problem lay with the computerized system
that controls the doors. The latter system is reportedly part of a
$1.4 million security upgrade installed at the prison by a company in
Alabama named Black Creek
Integrated Systems.
The control panel for the system
generally features a group-release button that allows guards in
minimum-security facilities to release inmates simultaneously for a
head count, the Herald reports. But it’s generally not
used in maximum-security settings, since inmates are kept
one-to-a-cell and aren’t allowed to interact with one another in
common areas.
… But the correctional facility in
Florida isn’t the only one to experience a problem with its
electronic doors. Last April, just a month before the first Florida
incident occurred, a correctional
facility in Maryland had a similar problem when the locks on 500 cell
doors disengaged simultaneously at around 12:20 a.m. on a
Saturday morning.
A computer malfunction was also blamed
for this failure. Officials at the Montgomery County Correctional
Facility where it occurred said no inmates tried to escape, but about
20 police cars were called in to secure the perimeter of the facility
during the hour it took to fix the glitch and secure the doors.
Three days later, however, the locks on the cell doors disengaged
again.
Just because the RIAA has kittens
whenever they hear the word, does not mean BitTorrent is always used
for evil. The sync tool is probably the most interesting way to use
it.
File Syncing With BitTorrent
Sync
BitTorrent, Inc. — the company behind
BitTorrent — recently released BitTorrent Sync. BitTorrent
Sync works differently from standard BitTorrent clients. it’s
entirely private — you install the client, choose one or
more folders to share, and then link it up with other computers.
Files anyone places in their copy of the shared folder are all
automatically synced with all other copies of the shared folders.
In this way, BitTorrent Sync is a lot
like Dropbox. Unlike Dropbox, it doesn’t store your files in a
centralized server online — it just syncs them between computers
you own or computers your friends own. This means that it offers
easy file sharing over the Internet and, unlike Dropbox, you
can sync an unlimited number of files as long as you have the
space on your computers for them.
… It’s a great way to roll your
own Dropbox-like service and share files across the Internet without
trusting them to a central server or being limited by the
size of your cloud storage account.
