  2. Re:What is the point? on Update Brings Android USB Mounting To Chromebooks · · Score: 1

    As others have pointed out, it is about the provisioning and maintenance. Chromebooks are essentially interchangeable. Suppose I log into one and do a ton of work, and then it gets stolen that afternoon. My data is secure since it is fully encrypted (with TPM support), and if I log into a new one in a few seconds all my bookmarks, extensions, applications, etc are up and running. And of course my files are all in the cloud. The only thing I'd lose is anything cached offline (a la html5), or the local file store if you're dumb enough to keep anything on it (it is intended just to be a place to download/view files, or download them from website A to upload them to website B).

    For a more sophisticated setup provisioning just requires the admin to log in once using a special account, and then all the company's policies get automatically applied, and can be updated from a web-based dashboard.

    So, a small business just needs a laptop for each employee, and one or two spares in the closet. That is, assuming they can run entirely off the cloud. For a true cloud-based company the only local infrastructure they would require is a WiFi access point, and maybe a consultant to help set it all up. Compared to the cost of backing up, virus protecting, encrypting, and provisioning replacement laptops, it is a bargain. Now, if your small business skimps on that stuff then they could do it cheaper with a bunch of consumer laptops, but then you're rolling the dice anytime somebody loses a laptop (or browses the web with outdated antivirus), and your employees will spend a lot of time tweaking their desktops any time they get a new system.

    Oh, and employees can swap laptops without the risk of them getting into each other's data - the secure boot process ensures that nobody has root without you knowing about it, and individual home dirs are encrypted.

    I'm not saying Chrome is without fault or limitation - clearly it isn't going to work for everybody yet - at least not 100%. However, if I were running a small business not in the IT domain, I'd probably strongly consider it. Drive down the street on the way to work and 95% of the places you pass probably don't need any software on the desktop that can't run in a web browser these days.

  3. Re:You brush over the danger of hypoglycemia on Probing Insulin Pumps For Vulnerabilities · · Score: 1

    Yup, hypoglycemia is no joke - I help take care of somebody who is diabetic. Hospitals always error on the side of hyperglycemia as a result - it is harder for them to control sugar with everything going on so they'd rather go too high than too low.

    That said, I've heard that studies have shown that tight sugar control improves hospital outcomes. That being the case I don't know why hospitals don't just put all their diabetics on insulin IV pumps. Check their sugar hourly until you get a baseline and then maybe back off on the checks. If something goes wrong you can stop the pump and the insulin will clear very quickly (IV insulin has a half-life measured in minutes I think - much faster than even a pump). If they're concerned about interruptions/etc they could use lantus/etc for baseline coverage as well and augment with an IV.

    The more I've read up on pumps the more convinced I've become that we should be treating a lot more people with them. Sure, if you can get your A1C down to 6 or whatever without a pump and without hypoglycemic episodes, then why deal with the complications. However, many people have fairly poor control from oral meds and it probably is a lot better to be more aggressive. I'd also love to see continuous glucose monitoring become more popular - it would allow for more aggressive treatment and in the long term probably save a lot more than it costs...

  4. Re:My experience on Probing Insulin Pumps For Vulnerabilities · · Score: 1

    Well, why would anybody kill anybody?

    Certainly if you are going to build a medical device that uses wireless technology you need VERY strong security controls around authentication/etc. If somebody steals your handheld controller and does a mission impossible on it I could understand that no security is perfect. On the other hand, I shouldn't be able to take apart my insulin pump and then use what I learn to remote control your insulin pump.

    The wireless features are handy. The typical use cases I'm aware of are:

    1. You test your sugar with a glucose monitor. You tell the monitor what you are about to eat. The monitor recommends a dose, and upon confirmation tells your pump to administer the dose.

    2. You have a four year old with diabetes. You set the pump on full lockout mode so that they don't kill themselves, and then just manage their diabetes with the remote monitor. At the appropriate age you start teaching them what you're doing. You don't even have to wake them if they're sleeping to adjust things.

    Never owned a pump, but I've been the the position of having to shop around for them recently...

  5. Re:"Easy to make" on Probing Insulin Pumps For Vulnerabilities · · Score: 1

    Yeah, but in this case medical device #1 costs $5k - insulin pumps may be simple, but they are NOT cheap.

    In theory the whole reason medical devices are so expensive is precisely because the vendor has to ensure that stuff like remote wireless hacks can't happen.

    I've thought about what it would take to build an insulin pump. To do a cheap job probably wouldn't be very hard - a simple pump just needs a syringe with a plunger and a motor that runs at constant speed.

    But, start thinking about all the "what if's". The device has to be designed so that if you shake it the syringe or whatever won't push out a few mL of insulin, and then aspirate back in some air or interstitial fluid or whatever. If you try to change the syringe without detaching it from your body it shouldn't suddenly gravity flow or whatever. If you invert the thing it can't cause any problems. If the battery starts to go too low it needs to warn the user and not do something stupid like run at the wrong rate.

    Oh, and any random combination of keypresses/etc has to result in the device staying in a controlled state. Now, you can't prevent all user error like the user telling the device they just ate a cheesesteak when they skipped a meal, but you need a reasonably robust UI and never have a failure mode that results in something that doesn't make sense.

    So, something like an insulin pump requires both good software engineering and good hardware engineering. Oh, and our crazy regulatory/insurance system is going to probably require a bazillion tests to show that it meets some kind of medical outcome (and not just test that when you say you output 2 units per hour you do that). Then you're going to be selling thousands of these and not millions, so the per-unit sunk cost is pretty high.

    So, I can see why it costs a fortune.

    Big fines pretty-much destroy the ability for somebody to live a normal life (raise kids, pay for their college, etc). However, they have little impact on the ability of somebody to be a scumbag since there a man with no dependents can easily hide assets, not own anything like a house that is easy to sieze, use exceptions in laws to allow people to pay for living expenses, and so on.

    Aside from software issues, one of the major issues the suppliers had was trying to be too helpful; every hospital will insist they are somehow unique and by pandering to every possible requirement the scope of the software build simply exploded.

    Vendors do this all the time - since usually it is in their interests to do so. Most contracts are time-and-materials, so the more you shoot yourself in the foot, the more money the vendor makes.

    Why would an analyst for the vendor fight some bigwig doctor over the feature they want which will add six months and six million dollars to the project? First, they tick off a stakeholder who is used to getting what they want. Second, they make six million dollars less. Third, they make the project get six months closer to the day when they all lose their jobs. Finally, if the project never gets done nobody will ever be able to prove that the vendor couldn't have done it in the first place.

    The problem is that people get lost with how useful tablets are for those functions, and forget that for the average person who needs to actually CREATE something they often aren't well-suited to the job. Now, I'll grant that there are isolated cases where they do a better job than desktops, and for those uses I'm all for deploying them.

I can only think of a few KDE features that I miss - the smb:// and fish:// URLs in konqueror/etc being the biggest. I'm sure if I looked hard I could find something like this. I also wouldn't be surprised if they "just worked" if I installed konqueror and ran it under xfce - k3b and a few other apps work fine without the whole DE running. This way, when I'm not running those apps I don't have a bazillion shared objects in RAM and a ton of processes chewing up CPU.
