The State of ZFS On Linux

mdmkolbe Re:Unfamiliar (366 comments)

you can easily buy 100GB of RAM and a set of SSD

It sounds like you are focusing on a server setting. Would the CPU and RAM overheads be enough to be a concern in a desktop setting?

DARPA Wants To Kill the Password

mdmkolbe Re:I can't change my fingerprint (383 comments)

Hashing may prevent Yahoo from breaking into your Google account, but it doesn't help if someone acquires the pre-hash data (e.g. by lifting your fingerprint). The problem noted by the GP still stands.

Granted, random websites are less likely to be able to lift your fingerprint, but coworkers, roommates, and cashiers could do that pretty easily. When Mythbusters tested fingerprint scanners, even though Grant was on alert that they would try to steal his fingerprint, Kari got them by asking him to copy a stack of CDs.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

mdmkolbe Re:I know you're trying to be funny, but... (739 comments)

Yes, there will be some amplification effect, but I know plenty of well-known developers that do not have the abusive reputation that Linus has. For example, Larry Wall or Simon Peyton Jones. (I'd like to list more like Yukihiro Matsumoto or Guido van Rossum, but I don't hang out in those particular circles enough to really know.) Even accounting for the amplification effect, Linus is on the extreme end of the spectrum in this regard.

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

mdmkolbe Re:I know you're trying to be funny, but... (739 comments)

Yes, he uses harsh language at times, but who the fuck doesn't.

I don't, and most people in my professional circles don't. (At least not to the level and frequency that Linus is notorious for.) There are people who regularly do or who occasionally have a bad day, but those are the exceptions.

Half of Germany's Power Supplied By Solar, Briefly

a combination of wind, gas, and nuclear is the most effective and practical approach to significantly reduce carbon emmissions

Wind and nuclear I understand, but how does gas significantly reduce carbon emmissions? Isn't it still burning stuff and thus producing CO2? How is gas better than coal in this respect?

Traffic Optimization: Cyclists Should Roll Past Stop Signs, Pause At Red Lights

mdmkolbe Re:So a bicyclist is safer..... (490 comments)

When you say the Uniform Traffic Code "has it in there", by "it" do you mean a prohibition or just addressing the question either way? It sounds like you mean a prohibition, but with the exception of Wisconsin, it is legal in every state you mention (though some prohibit it in "business districts" or allow municipalities to locally prohibit). (Though even in Wisconsin, it can be overridden locally.)

That makes 13 states that allow bicycles on sidewalks and 2 that prohibit it (at least by default).

I don't know about a Uniform Traffic Code, but the Uniform Vehicle Code permits bicycles on sidewalks. (Sec. 11-1103 exempts human powered vehicles such as bicycles from the prohibition on vehicles driving on sidewalks and 11-1209 presupposes the legality of bicycles on sidewalks.)

Traffic Optimization: Cyclists Should Roll Past Stop Signs, Pause At Red Lights

mdmkolbe Re:So a bicyclist is safer..... (490 comments)

Which five states? Do you have a citation on that?

A random googling of "[state name] bicycle on sidewalk" turned up seven states where there is no such side-wide ban (Florida, Oregon, Illinois, California, Utah, Washington, and Navada). Thus, I have to doubt your assertion without further evidence. I only found one state (Georgia) where it is illegal. I can't say about the other states (I was too lazy to do all 50), but my sample seems to contradict your claim.

(Disclaimer: I am talking about side-wide bans. Municipalities are another question. Also, many states regulate bicycles on the sidewalk (e.g., must yield to pedestrians, etc.), but I do not consider those bans.)

Traffic Optimization: Cyclists Should Roll Past Stop Signs, Pause At Red Lights

mdmkolbe Re:So a bicyclist is safer..... (490 comments)

they'll ... ride the sidewalks when convenient, etc.

In many (most?) parts of the country sidewalks are legal for bicycles. (Of course, this varies locale. Maybe it is legal where you are, but there is a broader point to be made.)

For some reason, drivers are surprisingly ignorant of bike laws. Half of them complain about bikes "illegally" using sidewalks instead of roads while the other half complain about them "illegally" using roads instead of sidewalks.

Study Finds US Is an Oligarchy, Not a Democracy

mdmkolbe Re:Terrible summary of an interesting paper (818 comments)

No, this is the very definition of oligarchy:

oligarchy, noun: a small group of people having control of a country, organization, or institution.

The GP describes a money-archy (monetarchy?). How they act and how counteract them are subtlety different. (E.g., grass roots can make a difference if they get money.)

Nature Publisher Requires Authors To Waive "Moral Rights" To Works

mdmkolbe Re:Reply from the Nature Group (82 comments)

The “moral rights” language ... is there to ensure that the journal and its publisher are free to publish formal corrections or retractions of articles

In that case, the language should limit the waiver of moral rights to such cases. Something along the lines of "The Author grants NPG permission to publish corrections to or retractions of the Work". See, no broad waver of moral rights necessary.

Ask Slashdot: Best Way To Implement Wave Protocol Self Hosted?

mdmkolbe Re:I'm 40 and what is this? (112 comments)

Wave was marketed as a successor to e-mail, but (1) that just confused everyone (because what does "successor to e-mail" even mean) and (2) in my experience that was not a good way to view it.

A simpler way to view Wave was as a federated form of Google Docs with added support for threaded conversations in the style of e-mail threads or chat logs.

If we want to break it down, Wave is/was a federated, personal, realtime, wysiwyg wiki with strong support for threaded conversations, sharing, history, and privacy and access controls. This combination of features means that wave can be used for a wide variety of communications from chat to e-mail to blogging to collaborative document writing.

Wiki: I'm going to assume you are already familiar with the "Wiki Way". Basically a "wave" document is a wiki page that you create and can freely edit.

Threaded: While wave allowed multiple users to edit document as holistic entities, it also supported structuring documents as a mailing-list style tree structure of threaded replies. Private side conversations not visible to the entire group were also supported.

Realtime: Perhaps the most important feature of Wave was that your edits were instantly viewable. If you and a friend make successive edits, it can be used as a chat system. (Wave had support to make this easy and so each additional edit could be appended at the end.)

Personal: The wiki documents that you create exist in their own private namespace (e.g. just like documents on different webservers) and usually (always?) are just internal identifiers not intended for to directly manipulate. This avoids the problem that standard wikis have of dealing with contention for document names.

Sharing: You could send a "wave" document to another user and have it appear in their inbox. You could also invite others to participate in an existing wave. Your inbox would also be notified when a wave that you were watching was updated (e.g. like how you receive a reply to an e-mail).

Privacy: Wave documents are by default not publicly visible and have sophisticated and easy to use access controls.

WYSIWYG: User's edit their documents as they would in any modern word processor or e-mail client without having to know about any sort of wiki syntax.

History: Like any good wiki, wave supported viewing older versions of a document.

Federated: I can run a wave server and you can run a wave server and both of them can interoperate. This is similar to how different companies can run different e-mail servers and unlike private communication systems like Facebook messaging. For people who want to maintain a free internet, this is an important feature. However, unlike e-mail, the authoritative copy of the document stays on the creators host. Though there is support for caching, I never clearly understood where wave fell on the problem of hosts lying and trying to rewrite history.

In the end, Wave was a good product that was marketed poorly (the marketing explanations left people not knowing what it was). The efforts to make it federated required the creation of a public spec which also probably slowed down development.

I think Wave was an awesome idea and others should build on its concepts, but shouldn't tie themselves to how those ideas were implemented in wave. In particular, the rise of Facebook may have changed what people expect from their communication platforms so some of Wave's ideas may need to be updated to encompas that. (I don't use Facebook so I don't know what those changes would be.) But if the next social platform were to support Wave-like ideas, then it could be very nicely positioned as a Facebook-killer as it could represent a next-generation advance in social platforms.

Drive With Google Glass: Get a Ticket

mdmkolbe Re:Not, however, if it's handsfree (638 comments)

If the legislators aren't creative enough to make a law that makes driving with an open laptop in the driver's lap illegal but not an open laptop in the passenger's lap, then they have no business being legislators. (Not that that has ever stopped them.)

(Side note, someone else in this thread posted the actual California law. I was misled by the AAA summary. Unless I missed something, there is no "equipped" requirement and it includes "business applications" in addition to TV broadcasts.)

Drive With Google Glass: Get a Ticket

mdmkolbe Re:Not, however, if it's handsfree (638 comments)

Note the key words "equipped" and "usually displaying a television broadcast". Wearing Google Glass does not "equip" the car with a video screen any more than the passanger holding a laptop does. Also Google Glass is not "usually" used for displaying a television broadcast.

Making Google Glass illegal while driving might be a good idea, but what you're citing doesn't apply to Google Glass.

Oregon Extends Push To Track, Tax Drivers Per Mile

mdmkolbe Re:Partisan BS (658 comments)

As for the meters, that is just for a pilot program the real program will not use that, it will use odometer checks.

Why would the pilot program use the more expensive, harder to implement option of meters if they don't intend it in the real program? Unless there is a really good reason that the pilot needed meters instead of odometers, I can't believe the claim that the meters are "just for the pilot".

NSA Director Keith Alexander Is Reportedly Stepping Down

mdmkolbe Re:Running away (92 comments)

Nixon was pardoned for any crimes he "might" have committed, so I don't think it requires admission of guilt. (Though there might be a perception of guilt and political fallout from that.)

Even if it did, Obama could just pardon him on his (Obama's) last day of office. If they delay the trial with pre-trial motions for a couple of years, the pardon would come through before anyone does any time.

(Of course, given that there isn't any real suggestion of an actual trial, this is all academic speculation.)

Boston Marathon Bomber Charged With Using 'Weapon of Mass Destruction'

mdmkolbe Re:Yes (533 comments)

It is something that other nations managed to get right with prosecutors needing to pay for accusations that don't result in convictions.

What mechanisms do other nations have to make prosecutors pay for over-charging? I presume it's not a monetary fine because that would bring a whole host of issues, but I'd be interested to hear what mechanisms have been instituted.
