Sony Leaks Reveal Hollywood Is Trying To Break DNS

markhahn ssshh, nobody tell them about BGP (378 comments)

the DNS idea is stupid, but not surprisingly so, given the level of practice the Sony hack has disclosed.

A Paper By Maggie Simpson and Edna Krabappel Was Accepted By Two Journals

markhahn missing the point (100 comments)

Fake and/or predatory journals are an interesting phenomenon with repercussions greater than just whether they accept nonsense papers. Could the poster edit to include some commentary on why this is interesting?

Consortium Roadmap Shows 100TB Hard Drives Possible By 2025

markhahn heat and patterned-media (215 comments)

interesting that these density improvements could both be applied to tape as well.

yeah, "tape yuck", but it makes a certain amount of sense for cool data. which we have lots of, always increasing. tape seeks are a minute or so, and if density is competitive, tape has a good chance to beat disks on price. certainly on power. the real problem is that the tape industry seems to be sort of demographically challenged...

Cameron Accuses Internet Companies Of Giving Terrorists Safe Haven

markhahn because they can (183 comments)

Imagine the amount of mayhem being tacitly supported by makers of paper and pens.

Politicians think they are right to demand control of behavior because it is, theoretically possible. They don't seem to appreciate that their model for the online world is flawed: it's not like physical space, compact and easily policed. The net is a communication medium, which can no more be policed than paper, phones or *air* can be cleaned of mayhem...

Smartphone App To Be Used As Hotel Room Keys

markhahn nothing is 100% secure (150 comments)

In a just universe, whenever some knob uttered a platitude like that, they'd be struck by lightning or a meteor or turned into a pillar of salt.

yes, I definitely would prefer a potentially secure wireless protocol over an obviously insecure physical key. this is a no-brainer! even better: make it a public, *STANDARD* secure wireless protocol, preferably exactly the same one I use to authorize NFC payments from my phone.

If You're Connected, Apple Collects Your Data

markhahn It's because they care! (313 comments)

What kind of antisocial fiend would blame Apple for wanting to play a role in customer's lives? After all, isn't that sort of why Apple people buy Apple in the first place, the need to belong, to be involved in something bigger than themselves? You know: every sparrow, etc, etc.

Microsoft Partners With Docker

docker is anti-Unix in significant ways, so should be a great match for Msft - maybe with some systemd to spice up their love-life.

Co-Founder of PayPal Peter Thiel: Society Is Hostile To Science and Technology

markhahn Re:Its not the technology - it is the tech company (238 comments)

The problem with corporate taxation is that it's based on profit, not income. Personal tax is always income based - imagine if you were only taxed on the income you didn't manage to spend each year! If corporate tax was based on income, it would be commensurable (and would presumably also be a much lower rate). Corporate INCOME tax would also make all these tax dodges irrelevant, since they work only because companies manipulate their profit.

Why the FCC Will Probably Ignore the Public On Network Neutrality

markhahn What don't they understand about (336 comments)

"government of the people, by the people, for the people". our system seems to have lost track of the basic principles. just as the courts ignore portions of the constitution, such as "to promote the progress of science and useful arts", or "a well regulated militia being necessary to the security of a free state".

China's claim is absurd; no one else in the world considers these islands disputed. No amount of dredging is going to change that.

Supermicro Fails At IPMI, Leaks Admin Passwords

markhahn user error (102 comments)

it's crazy to expose IPMI to the public net. yes, that might mean you need separate wiring for an internal subnet, and you might not be able to use all your ports for public access - just read the docs before you buy it.

Ask Slashdot: Communication With Locked-in Syndrome Patient?

markhahn ERP (552 comments)

First, recognize the need for empirical information on the state of your loved-on. It is of very little use to make subjective observations, since humans are incredibly good at finding patterns where none exist.

Second, recognize the difficulty of what you're undertaking. Humans are at the very beginning of understanding how our bodies work, and we have essentially no model to predict when patients will, or never will, recover from injury like this. What makes it hard is that this ignorance means that you will be trying to make decisions under extreme uncertainty - but that doesn't mean you shouldn't do so. For instance, there should probably be a time past which you withdraw life support when there are no signs of recovery. No one knows how long that should be, but the key thing is whether there are signs of hope.

What would be such signs? You've already read something about the locked-in phenomenon. First, CT cannot possibly provide any information about function: it measures x-ray density, and provides only structural information. At best, it might show which tissue has died - but unfortunately, we have very primitive knowledge of how that relates to function (or recovery). ERP (scalp electrodes) are MUCH more relevant: there is a huge literature describing the sorts of obligate responses made by sensory portions of the brain (our understanding of less sensory processes is rather spotty). PET can map metabolic activity, but that has a much less obvious relation to organized, functional brain activity. I think ERP monitoring should be your primary path forward. There is lots of research on this topic, and pretty much any university psychology/neuroscience/psychiatry department would have well-informed people you could talk to, often ones able to perform ERP tests for brain function. (The technology of ERP is very not hard, and designing effective tests is somewhat subtle. But if a test is supposed to guide a decision like continuation of life-support, it's not a casual trip-to-radioshack kind of project.)

In short, find a non-self-deluding way to gather empirical signs of functioning personhood; in the absence of such signs, figure out how long to wait.

Ask Slashdot: Communication With Locked-in Syndrome Patient?

markhahn Re:As painful as it is... (552 comments)

this is NOT insightful.

we (medical or scientific communities) do not have the understanding to guide such a decision. we simply can't tell when a patient will never recover.

I personally would not want to be kept alive without prospects of a quite high quality-of-life. others certainly have different thresholds, and none of us can gainsay that preference. to do so is murder.

SanDisk Announces 4TB SSD, Plans For 8TB Next Year

markhahn arrgh (264 comments)

ssd vendors should be rushing to get nvme out the door, rather than wasting time on capacity. flash does not and simply never will scale the same way capacity in recording media (including that mounted in spinning disks) does...

Oklahoma Botched an Execution With Untested Lethal Injection Drugs

markhahn why not just OD? (1198 comments)

I'm not convinced capital punishment is a sound choice, but why do they make such a big deal about it? there are opioids that would cause prompt and relatively peaceful death, not to mention extremely powerful muscle-relaxants.

SSD-HDD Price Gap Won't Go Away Anytime Soon

markhahn duh (256 comments)

with spinning rust, you might re-engineer the bulk process that coats your disks, but the boost in recording density depends on changing the parameters of the head. bulk process and one device. compare to flash, where to boost density, you have to tweak each storage cell, controlling for defects and manufacturing flaws, where the yield of each cell multiplies, so defects are exponentially likely.

disks (and to some extent tape) will always have scaling advantages over litho-fabed storage.

you can certainly argue that latency and bandwidth also suffer by the same process - but for the most part, disk performance really is fast enough for most uses. it's a bit surprising that more disk vendors haven't tossed onboard a small flash chip (to all lines of HDs).
