While setting up Retrospect, I ran into a number of problems, most of which I think I solved. I’m just noting some of them here, so I can find them again. Or so you can find them, perhaps. I’ll add to this post as I encounter more oddities.
Now that Crashplan for home is gone, or at least not long for this world, a lot of people will need to find another way of backing up their stuff. It’s tempting to get angry, and there are reasons to be, but in the end you have to forget about all that and move on. Even though you may have months, or even a year, before Crashplan stops working, there is another reason you have to get something up right now, namely file histories.
I just discovered that Parallels v12 has a really nice feature, namely to stop Windows from doing updates except for a predetermined period. Brilliant! It’s also a sad testament to what Microsoft has done when it comes to respect for the user’s time and work.
When applications are in “quarantine” on OSX after being downloaded, they are run in a kind of sandbox; they’re “translocated”. You don’t really see this, but weird things then happen. For instance, Little Snitch won’t let you create “forever” rules on the fly, claiming your app isn’t in “/Applications”, which it clearly is if you check in Finder.
The problem is that the extended quarantine attribute is set, and needs to be reset (at least if you trust the application). Too bad Apple didn’t provide a GUI way of doing that, so here goes the magic incantation (assuming WebStorm is the problem in the example):
First check if the attribute is set:
Then if you see that it is, reset it:
xattr -d com.apple.quarantine /Applications/Webstorm.app/
…and there you go. Life is good again.
This is a neat service that lists torrents downloaded for any given IP. See what your kids do while you’re not watching. Or maybe your neighbours? It’s a little bit scary.
I think the major problem is that buyers specify domain functionality, but not the huge list of “non-functional requirements”. So anyone fulfilling the functional requirements can sell their piece of crap as lowest bidder.
Looking at a modern application, non-functional requirements are stuff like resilience, redundancy, load management, the whole security thing, but also cut-and-paste in a myriad of formats, a number of import and export data formats, ability to quick switch between users, ability to save state and transfer user state from machine to machine, undo/redo, accessibility, error logging and fault management, adaptive user interface layouts, and on and on.
I’d estimate that all these non-functional requirements can easily be the largest part of the design and development of a modern application, but since medical apps are, apparantly, never specified with any of that, they’re artificially cheap, and, not to mince words, a huge pile of stinking crap.
It’s really easy to write an app that does one thing, but it’s much harder and more expensive to write an app that actually works in real environments and in conjunction with other applications. So, this is on the purchasers’ heads. Mainly.
This article is an excellent description of some of the serious problems related to IT security in healthcare.
Even though medical staff actively circumvent “security” in a myriad inventive ways, it’s pretty clear that 99% of the blame lies with IT staff and vendors being completely out of touch with the actual institutional mission. To be able to create working and useable systems, you *must* understand and be part of the medical work. So far, I’ve met very few technologists even remotely interested in learning more about the profession they’re ostensibly meant to be serving. It boggles the mind, but not in a good way.
“Unfortunately, all too often, with these tools, clinicians cannot do their job—and the medical mission trumps the security mission.”
“During a 14-hour day, the clinician estimated he spent almost 1.5 hours merely logging in.”
“…where clinicians view cyber security as an annoyance rather than as an essential part of patient safety and organizational mission.”
“A nurse reports that one hospital’s EMR prevented users from logging in if they were already logged in somewhere else, although it would not meaningfully identify where the offending session was.”
This one, I’ve personally experienced when visiting another clinic. Time and time again. You then have to call back to the office and ask someone to reboot or even unplug the office computer, since it’s locked to my account and noone at the office is trusted with an admin password… Yes, I could have logged out before leaving, assuming I even knew I was going to be called elsewhere then. Yes, I could log out every time I left the office, but logging in took 5-10 minutes. So screen lock was the only viable solution.
“Many workarounds occur because the health IT itself can undermine the central mission of the clinician: serving patients.”
“As in other domains, clinicians would also create shadow systems operating in parallel to the health IT.”
Over here, patients are given full access to medical records over the ‘net, which leads physicians to write down less in the records. Think this through to its logical conclusion…
Visa has a neat feature where you can determine in which regions the card can be used. In my case, it’s “internet”, “Sweden”, “Nordic countries”, “Europe”, “North and central America”, “South America”, “Africa”, “Asia”, “Oceania”. You can set these through the credit card app (mine is from Volvo, of course).
So I disabled all regions except “Internet” and “Sweden”, planning on enabling other regions when I travel.
Today I got a message from Netflix that they couldn’t charge my card. No explanation why. I called the card issuer and after some digging they explained to me that since I disabled “Europe”, Netflix got refused. Turns out that Netflix charges from region “Europe”, not “Internet”. More specifically from The Netherlands. Once I reenabled “Europe”, the charge went through.
Now, there are several problems with this. First of all, an internet based service like Netflix should be in the region “Internet”. Secondly, if it isn’t in “Internet”, they should at the very least tell us from which region they charge. I had no idea Netflix charges from The Netherlands. How could I? It’s not reasonable to expect us to check with the card issuer every time this happens, and have them go dig through logs (took them 10 minutes to find, so it wasn’t trivial).
Worst of all, this kind of thing implies that you’d better open up a lot of regions you’re not travelling to, since you don’t know from which regions different internet based companies do their charging.
Having the card processor issue meaningful error messages, not just “sorry we failed”, would definitely help a lot, too.
Feinstein-Burr senate bill, it’s getting crazier by the day:
No, this slippery little act says that when a company or person gets a court order asking for encrypted emails or files to be handed over and decrypted, compliance is the law.
How compliance actually happens isn’t specified. They don’t care how user security was broken (or if it were nonexistent), and the senators are making it clear that from now on, this isn’t their problem.
