mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
->This is a good idea, but it is obvious it needs quantum cryptography to succeed

not a million miles from

->I think you'd still only have a solution which is workable against a very limited set of adversaries - namely, the ones who play by the rules, more or less.

which is exactly why i said "a bit strawman"

perhaps where we differ is you think encryption only keeps information safe from those who play by the rules?

mSparks··on German research institutions boycott Elsevier
while this isnt in any way a scientific observation, it does feel that the quality of elsevier publications has been falling recently.

it seems it was 2013 the last time they were shouting about rising impact factors.

losing all of germany will certainly hit the various if hard.

mSparks··on AMD Gives More Zen Details
pcmark and passmark measure a vast range of cpu performance use cases.

currently, amd does terribly in pretty much every measure. absolute performance, performance per $, throughput. absolutely anything that matters.

There are some promoted intel chips that are worse.

but the only thing amd have been doing well at in recent years is hyperbole with a healthy dose of shilling. So i cant disagree with anyone on here that wont believe anything they say until they see it.

around this time last year we had

mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
but thats the strawman.

"This is too limited because it doesnt help people taking the camera"

when the whole problem has nothing to do with taking the camera and everything to do with what happens afterwards.

the equivelent to "there is no point in encrypting your banking transactions because it wont stop someone stealing your wallet on the street"

-> typical strawman.

mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
but you seem to be talking about situations where concealed camera equipment is more suitable, or even just your run of the mill phone.

bit strawman?

what they are asking for isn't technically difficult or even that expensive to develop.

mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
did you rtfa?

the problem these guys are facing is not the encounter.

its that the images and video can incriminate and cause repercussions for people not at the scene but stored on the camera.

such as those guys with you ak47s you are complaining about who were helping the journalist get their story of governmental abuse of power.

or that police officer confessing his coworkers corruption.

mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
yeah, the great and the good of film and photography giving you their backing means nothing these days.

at least that is probably what trump has been telling himself at night since everyone turned him down to perform at his inauguration speech.

for everyone else. kinda a big incentive.

mSparks··on Filmmakers Ask Nikon and Canon to Sell Encrypted Cameras
thats why it should be a technical impossibility to recover them in the field.

i think it would even do to have it done "offline" - i.e. any image/audio/video older than a few minutes gets encrypted and can only be decrypted at another location.

that should also be an optional mode. so you can have lots of wildlife photos and pictures of cute cats for plausible deniability.

mSparks··on AMD Gives More Zen Details
you've seriously never heard of pcmark or passmark?

noob alert :p

mSparks··on AMD Gives More Zen Details
https://www.cpubenchmark.net/high_end_cpus.html top of the range $200 amd fx 9590

less performance than a $133 intel e5 2650

and neither are worth buying today.

mSparks··on AMD Gives More Zen Details
hmmm.

I used to only buy AMD. Im not exactly sure where they are up to now (probably about 8 years if not more since I touched them)

but i definately remember the bulldozer hype and subsequent flop. lies about the number of cores and other things that just made me say "my computing is to important to my life to play that game".

I was also privy over the years to some test builds of machines including head to head amd vs intel. it is truly painful to say that not only were they often more expensive (new) for the performance, they were also horribly unreliable, pausing, and doing all sorts of stuff that made us sad.

hope thats changed, but saying there is any similarity between the current in use intel vs amd range is very far from the mark.

mSparks··on Things You Notice When You Quit the News
yes and no.

Ive noticed the economist has a habit of playing policy games.

In that case they publish nonsense to further certain policy aims.

But often its well researched unbiased material.

not that easy to tell the difference.

but infinately better than the junk put out by the likes of the bbc fox cnn times etc.

mSparks··on Belarus finally bans Tor
back in the day, using a bbs was grounds for a wiretap. (The fact bbs were full of phreakers had absolutely nothing to do with it im sure....)

so they sit, they listen, then do what exactly?

Someone has to read through the material, decipher it, translate it, interpret it. and how exactly do you act on it?

mSparks··on Ransomware gives free decryption keys to victims who infect their friends
popcorn time software is something completely different.

this sounds more like an attempt to taint the popcorn time name rather than real malware.

mSparks··on Belarus finally bans Tor
its easy to see both the upside and downside of this though.

its also only really a problem for americans. since the us government is paying to ensure other countries governments cant interfer with free communication.

its a matter of opinion wether they also managed to gain the ability to interfere with free communication themselves.

but since the "Next best alternative" is ssl/tls.

kinda a moot point.

mSparks··on Micron Announces 5100 Series Enterprise SATA SSDs with 3D TLC NAND
The benefit of 15k SAS drives is 250MBs per drive actual throughput, even more because they are RAID arrays - for 3c a GB, they are HIGHER performance than most SSD drives on the market.

Sticking "enterprise" on the box will not make enterprise pay 42c per gig for less performance.

mSparks··on Micron Announces 5100 Series Enterprise SATA SSDs with 3D TLC NAND
It seems "a bit pissy and inexperienced" that I would want to see actual performance figures before making an enterprise purchasing decision?

42c per gig is VERY expensive, more than 10 times the price of 15k SAS at volume. SSDs - while I didn't say "are not used" in enterprise - are "generally" not used. As in, for every $10mill enterprise spends on SAS drives, they spend maybe a few hundred thou on SSD.

The market for SSDs is elsewhere.

googles to check. YUP http://www.anandtech.com/show/10348/q1-2016-market-trends-ss... http://www.anandtech.com/show/10098/market-views-2015-hard-d... WD alone ships 3 times more enterprise HDD than the entire enterprise SSD market. roughly speaking Enterprise HDD is about the same size as the entire SSD market.

My pissy comes from HN becoming more and more "pimp my company/product" and downvote to hell anyone remotely critical, with less "news about hacking".

mSparks··on Micron Announces 5100 Series Enterprise SATA SSDs with 3D TLC NAND
in gerneral enterprise is not using ssds.

so you kinda missed the point.

and when the hardware they plug into is a sas interface, they arent going to be buying them either.

seriously, getting a bit tired of the immaturity and shilly nonsense on here.

check any rack machine from cisco, dell or any of the other big enterprise suppliers (of which intel is an oem, they dont really deal with the likes of hsbc or shell corporation) and they all come with sas interface for storage.

enterprise means "more than 10000 employees".

you do have dedicated support personel from your supplier.

intels "data center range" definately isnt enterprise imho. enterprises still not stupid enough to go anywhere near the cloud.

mSparks··on Micron Announces 5100 Series Enterprise SATA SSDs with 3D TLC NAND
I was commenting less "consumer v enterprise" and more "consumer vs consumer that pretends they are enterprise".

Enterprise servers are mostly sas interfaces. These are sata, which is mostly home and soho plus a few startups running on a shoe string (afaik)

mSparks··on Micron Announces 5100 Series Enterprise SATA SSDs with 3D TLC NAND
Not sure i buy into that. Sounds a lot like sales talk.

Be interesting to see how they compare with these guys:

http://techreport.com/review/27436/the-ssd-endurance-experim...

and, afaik, for enterprise, sas hdd still leads ssd in performance price and endurance.

mSparks··on HiFive1: A RISC-V-based, Open-Source, Arduino-Compatible Development Kit
I should have been more specific.

Radio signals below 50 kHz are capable of penetrating ocean depths to approximately 200 metres, the longer the wavelength, the deeper. The British, German, Indian, Russian, Swedish, United States [3] and possibly other navies communicate with submarines on these frequencies.

->That requires min 100khz sample rate.

mSparks··on Amazon States Language – A JSON-based language to describe state machines
Yeah, we still have a few critical components that serialise to xml rather than json, although they have mostly been replaced.

What's new this time is the pricing model. It used to be we could run what we wanted on our own hardware on our own time. SaaS is new, mostly impossible to pirate (hacking AWS keys aside), and priced to make your eyes water.

mSparks··on Crypto 101 – Introductory course on cryptography
All those attacks are "theoretical". As opposed to actually having been usefull in the wild - FUD (heartbleed otoh.....).

padding -> irrelevent to an RSA public key, everyone has to know the exact modulus and product, even the bad guys (although I recommend keeping public keys relatively secret)

timing -> irrelevent to an RSA public key, there is nothing you can get from how long it takes to decrypt or encrypt even 1024 bits of data (which is more than most impliementations even send), sometimes the exact same data will take 1ms, sometimes 100ms, it depends what else the machine is doing at the time.

mSparks··on Crypto 101 – Introductory course on cryptography
only one encryption scheme works against "willful targeted attacks" - the one time pad (and even that has potential for going wrong)

All the others are about making the effort required greater than the will to get there in favor of usability.

All the standard libraries stop at "miniscule effort for a state".

And states aren't even "the big boys" anymore.

mSparks··on Crypto 101 – Introductory course on cryptography
padding attacks are only really related to encrypting data not sharing the product of two very large primes. You clearly havent got the faintest idea what you are talking about.

Rather than putting the rest of us at risk by putting zero value on the security of anything you make and guessing someone [a spook] will do it for you, why dont you recommend everyone takes some time out to at least learn the basics.

Yes, there are several "mines" you need to be wary of.

But they all pale into insignificance compared to linking openssl and thinking you are done.

mSparks··on Amazon States Language – A JSON-based language to describe state machines
dia creates xml almost identical in nature to this json spec.

and if you need json, plenty of xml to json convertors knocking around.

mSparks··on Crypto 101 – Introductory course on cryptography
since im not in the market for downvoting. ill just say.

eh.

RSA is a simple formula. takes a bit of fiddling and skill to get BigIntegers working. but anyone who passed highschool algebra could roll their own. in fact many high schools even set it as homework.

timing attacks you say. erm, not remotely connected.

mSparks··on Amazon States Language – A JSON-based language to describe state machines
18 years late.

https://en.m.wikipedia.org/wiki/Dia_(software)

mSparks··on Amazon States Language – A JSON-based language to describe state machines
i have a project dating back around maybe ten or 15 years that could read the text format (xml iirc) of dia drawings and execute them.

the main problems included being actually very hard to understand visually, very ugly, and subject to all sorts of edge case errors when running. basically easier to write code then compile uml from that for anyone crazy enough to want it.

the crux of the problems is verbosity. Once systems start to get to a reasonable level of complexity the uml diagrams can cover the walls of a large room.

vs 1 page of a4 for pseudocode.
