Google sniffs at MySQL fork MariaDB: Yum. Have an engineer

Chris_Maresca

Re: Good News Everyone...

Open source is a licensing mechanism used by the owner of the code in question. It has nothing to do with 'retaining ownership' since that is related to copyright, not license.

Whomever owns the copyright owns the code and no open source license gives away ownership of the code. And in some jurisdictions (e.g. Germany) copyright is a right you cannot give away, it's a natural right like liberty. That's why pretty much every open source project now has a contributor's agreement which assigns copyright to the project (or the equivalent legal mechanism in places like Germany), thus allowing the project to control all the code. This is mostly a result of Mozilla's difficulty in changing the license to the Netscape codebase because they didn't control all the copyrights...

Re: commercial license

This is simply wrong. There is nothing in the GPL that says you can't use GPL licensed code for commercial use.

The only restriction is that if you distribute the application, you must make the source available, but that only applies to the GPL licensed code. The only place you might run into trouble is if you co-mingled the GPL MySQL drivers with your code, but most applications don't do that and it would be bad architecture to do so. Other than that, you can keep your code as closed as you like.

As someone else pointed out, there was a lot of FUD from MySQL about this, but it was just that, FUD.

T-Mobile US: Go ahead, PAY NOTHING up front for any device

Chris_Maresca

Re: this is aimed at getting people to churn away from handset manufacturers the carriers don't like

Huh? How on earth do you figure that?

T-mobile offers handsets from every major maker and all of the popular/wanted ones - except the new Nokia 41mp camera phone.... I might actually move my account to T-mobile as they are significantly cheaper than my current carrier and they have a fantastic selection of phones....

Re: So...?

Not really, that model has been around in the US for at least 20 years. It just never applied to very high end phones and there was no split between your service & hardware payments. What T-mobile has done is split the coupling between HW & service, then done away with the upfront HW payment.

Month to month contracts have been available for years but are more expensive and there is zero device subsidy (like in Europe, BTW). The last time I was in Europe (and was shopping for a phone), you had to pay an upfront fee for the most expensive phones, even if they were subsidized by a monthly contract.... Plus devices were only subsidized on 12 to 24 month contracts, month to month contracts required you buy the device outright.... Never mind that if you wanted an Apple product, the upfront fees were far higher than typical US carrier fees.

Bolivian president's jet grounded so officials can look for Snowden

Diplomatic immunity

I carried a diplomatic passport for a number of years and my wife is currently a consular official. Here are some general rules about diplomatic immunity.

1. The person, residence & vehicle of an accredited diplomat are considered sovereign territory of the diplomats home country. Entering the premises or vehicle is the equivalent of crossing a border. My wife technically commutes to a foreign country every time she goes to work and a different set of laws apply to her when she is at work.

2. It is possible for a diplomat to confer diplomatic immunity to another person even when not in their residence or vehicle. This can be done by holding on to someone. The West Germans famously did this when East Germans were scaling the fence around the West German embassy in Prague, circa 1989.

A couple of things to note:

1. To have full immunity, you must carry a letter of accreditation from the host government. Even without it, you have partial immunity, but it is much, much more tenuous.

2. The rules are just rules, there is no way to actually enforce them. Governments have ultimate and unlimited power (theoretically) over individuals and diplomatic immunity will not protect you if they go all out.

3. Heads of state generally have a different, higher level of immunity in foreign countries than diplomats. I'm not entirely sure what the legalities are, but I do know from personal experience that head of state status allows for things that diplomats could never, ever do.

I find this whole thing rather strange. If I had been in Morales' place, I would have ordered the plan to fly on as there was little that any government could do stop it short of shooting it down. It's a matter of principle as much as anything else, a sovereign head of state is just that, sovereign.

It's a disturbing precedent to say that if you are a relatively weak country your sovereignty counts for nothing. And searching a head of state's plane is pretty much the same as invading a country to look for someone/something. This whole thing reeks - it's a sad day when someone vocally opposed to the US can't find refuge anywhere and even sadder when states resort to violating sovereign immunity as a means to an end.

Not work! - Firmware hacks

Chris_Maresca

Some background info & suggestions

It runs a proprietary Motorola OS called P2K, IRC. AFAIK, there aren't a lot of hacks, although one way in might be bluetooth as I believe they used the BlueZ open source stack at the time.

You might see if you can get a USB data cable for it. Some platforms allow greater access through these connections (aka Sony Ericsson) which allowed people to hack the platform. I don't know it would do any good, but it's worth a try. In a similar vein, you might crack open the phone (or another working copy) and try to identify a JTAG header....

Also, see if you can download software updates. Sometimes you can unbundle these and modify them. A lot of old skool phone hacks were done this way, then flashed through USB data cables...

Finally, I know for a fact that the 'modem' (the part than handles communicating with the network) is a physically separate processor from the one running the OS. This was done for security reasons and specifically to make it MUCH harder to hack.

Overall, I would rate your chances of achieving anything meaningful as pretty low. The reason I say this is that, at the time that phone was new, I was at Motorola trying to get them to open it up so people could write apps and there were a LOT of technical barriers that made hacking it very, very difficult. That said, they did setup a dev site and there might have been some code up there, although I don't think it was for the P2K platform but for Brew (if anyone remembers that).

When Apple needs speed and security in Mac OS X, it turns to Microsoft

Chris_Maresca

Re: They are probably using Samba, not Microsoft's code

Actually, it's highly likely Apple is using MSFTs code under license given that they released their own implementation a few years ago.

Otherwise, building your own SMB implementation from scratch would be a nightmare (as the SAMBA team found out early on...).

Which would also explain why they are favoring SMB over NFS or AFP. After all, they already have a license and a dev team dedicated to it.

Now if shares would just auto-remount after my Mac goes to sleep, it would be perfect.... (yes, I know all the ways this is supposed to work, but they just don't...)

Re: Hmmmmmmmm

One of the reasons for this is that Samba changed it's licensing, which forced Apple to write it's own implementation. http://reviews.cnet.com/8301-13727_7-20046383-263.html and http://apple.slashdot.org/story/11/03/24/1546205/apple-remove-samba-from-os-x-107-because-of-gplv3

I would bet that Apple is licensing code from Redmond to make this process faster*, pretty much guaranteeing that SMB2 will be the default file sharing protocol.... Note that Apple's current SMB implementation, while claiming SMB2 compatibility, actually only talks SMB1.

* we all know how much work it took to reverse engineer SMB for Samba to work right & the resulting patent/IP fight....

Red Hat to ditch MySQL for MariaDB in RHEL 7

Chris_Maresca

One unique feature

of MyISAM tables is the MERGE table definition. It allows you to merge two tables, even if they are in different databases, so that they look like one table to anything querying the DB. Kinda like a view, but the difference is that you can then specify which table is writeable and all writes will go to that table only.

This can come in very, very handy if you have to do something like have common data in several DBs but can't change the application. I don't know of any way to easily do this in other DBs, although there are some things which come close.

It does have some limitations, like the tables having to be exactly the same and you need to make sure to avoid key collisions. But when your use case calls for something like MERGE, it's a good solution.

MYSTERY Nokia image-mangling mobe spotted in public

Chris_Maresca

Re: Windows phones built to Microsoft's hardware recipe

Real photographers don't care that much about gear, it only really matters if you are doing studio shoots where you can control absolutely everything. Also, low light situations are still difficult for phone cameras.

There are a number of award winning photographers that have produced stunning images on very low end gear. Anything from superzooms to iphones.... And the Chicago Tribune has just laid off it's entire photo staff, saying it will train reporters to use iphones for photos & video. For a lot of professionals these days, a connected camera is much, much better than a standalone camera since immediacy is what wins eyeballs. In that context, a phone with a great camera is perfect.

Besides, most camera phones these days are 10x better than early digital equipment. I'm currently doing a project with some 10 year old high-end digital digital cameras and it's easier to get great pictures from an iphone.... Funny thing is that it's a processing & software issue (autofocus, metering, white balance, etc), not the hardware.

Finally, stats - http://www.flickr.com/cameras - no one uses cameras anymore (other than very high end stuff)

As someone once said, the best camera is the one you have with you.

AWS taps social networks for identity verification

Chris_Maresca

Seems redundant

Most (all?) major programing languages have easy to use libraries for openID & Oauth, both of which underlie this service. There is also widely-available browser-side code for users to pick an auth provider.

And, in the end, you still have to keep track of your users somehow, so it's not like you can actually get away with zero server-side code for anything but the most basic app.

That said, being able to login to the AWS console using federated credentials is a very good thing as it allows for centralization of auth credentials (makes it easier to change/revoke all at once...).

Prankster 'Superhero' takes on robot traffic warden AND WINS

Chris_Maresca

Re: Excuse me, sir...

Thing is in most jurisdictions, photo tickets are illegal in a variety of ways and very, very easy to defeat. BTDT twice. Most people loose in court because they are using some random excuse, not a technicality based in law. One of the easiest ways to defeat it is to do a discovery request on the contract between the municipality & the photo company. 9 out of 10 times this will be refused and your case will be dismissed.

Rules, shmules: Fliers leaving devices switched on in droves

Chris_Maresca

I was on a flight a week ago - of the people in my row, only I powered down my device - pretty sure everyone else just put theirs in airplane mode...

How do I know? Well, on landing, the others were instantly using their iPhones - mine took about a minute to boot up....

I actually think that people believe that airplane mode is all that's required and don't actually know how to fully power off their devices. My guess is that only 30% of fliers actually power off their devices.

Dell directors foresee unremitting brutality in PC market

Re: The Tree is Dead

I have the exact reverse - HP has always been much better to me (once even did a 2-day turn around on broken laptop over a weekend during x-mas holidays...) than Dell (my experience mirrors the above script...) over the last 20 years. So much so that I would never, ever buy another Dell, although I might buy an HP. That said, I mostly only use Macs these days which rarely fail and manage to retain their value for more than six months....

Steve Jobs' death clears way for Adobe CTO defection

Chris_Maresca
Thumb Down

Kevin Lynch has no vision...

In 2006, I was hired by Adobe to do a strategy review of mobile flash. What I said was that there was an opportunity for flash to be the default UI for mobile, but only if they open sourced it as it was clear that some sort of Linux on mobile (aka Android) would emerge as the leader and an ecosystem would form around it.

Kevin was aggressively against the idea, couldn't see where mobile was headed, that flash was in danger of being an also ran and that there was an opportunity for Adobe to lead in a new market of mobile, apps and data.

I hope Apple understands that they are hiring mr status quo. Actually, they probably do since they are coasting on the energy & innovation of Jobs. This is just another sign of a long, slow decline....

Why you need a home lab to keep your job

AWS anyone?

Seriously, there are few reasons to have a lot of servers at home, particularly if you are focused on software. Learn how to build, deploy & manage cloud infrastructure - that's high value and you don't need a rack full of servers in your house.

I used to have a 'home lab' as well, but I've moved on to more modern infrastructure hosted elsewhere....

Microsoft to end Windows 8 discounts on January 31

Chris_Maresca

Re: Shooting themselves in the foot? - yes, by releasing Win 8.

Funny enough, Windows 7 is far better than Linux on my laptop - battery life is around 30% longer and all the hardware works perfectly. The reality is that, as a consumer desktop, Linux still has a long, long way to go, although I agree that OSX is far better than either Windows or Linux.

Linux is usable on the desktop, but it's not nearly as easy for the average person as either OSX or Win7. And those people don't know what a command lines, file paths or directory layouts are. And the fact that you focus on these things as why Windows sucks is exactly why Linux is still a crappy desktop...

Orange boasts: We made Google PAY US for traffic

Chris_Maresca

Peering agreements vs depeering

Why is this surprising? Google is exactly like any other large network operator, it negotiates peering agreements with other networks. When there is a traffic imbalance, peering agreements often move from settlement-free peering to depeering, where one network pays another to carry the excess traffic.

It's not odd, new or bad. It's the way all networks have operated since the beginning of networks, although internet traffic was often not imbalanced between networks, so settlement-free peering was the norm for a long time. However, that has not been the case for a while, people have been paying for various forms of depeering for at least 10 years, either through edge-caching, via telco-run carrier hotels or simply paying for fatter pipes/cache co-location directly to telco-owned ISPs...

I'm not surprised France Telecom/Orange are making money from Google. They are a virtual monopoly in France, both on the bulk carrier and ISP sides, and probably in carrier hotel as well. They are also a major mobile carrier in globally (another form of ISP these days) and probably have a dominant position in most of Francophone Africa.

I'd be shocked if France Telecom/Orange were not making millions from Google through selling them fat pipes (dark & live) and co-location at their network edges, never mind datacenter space...

'SHUT THE F**K UP!' The moment Linus Torvalds ruined a dev's year

Chris_Maresca

Re: Torvalds is the greatest manager of them all

I suggest you lookup 'flame war".

This is hardly abuse in the context of what is the equivalent of a bunch of programmers meeting & discussing other people's code, particularly on a mailing list. And, you know nothing of either the way programmers discuss code or of the relationship between the people involved. The only thing you see is a snippet of a discussion and draw conclusions from only that

Oh, and Linus doesn't have any managerial duties at the Linux Foundation.

Hey, cloudy tech vendors on Amazon: AWS can fluff you up

Chris_Maresca

You need to architect for AWS

Reducing costs by hosting on AWS is not just about re-provisioning existing systems with AWS instances, you have to architect apps to take advantage of the way AWS works. This requires an understanding off all AWS services and figuring out how to map those to your needs.

I spent the last 5 months doing this with a client's application and we reduced hosting costs to roughly 10% of what they were compared to traditional hosting.... Of course we spent about 3 months re-engineering parts of the application, but in the end that work also made it more robust and scalable.

Also, if you have an app with spiky demand that needs to scale rapidly (e.g. customer facing) then AWS is a great solution - see http://www.theregister.co.uk/2012/04/30/inside_pinterest_virtual_data_center/ for Pinterest experience in doing this and keeping their hosting costs to $35-$52/hr.

Review: Samsung Series 9 super slim notebook

Chris_Maresca

I had a 2 lb laptop in 1995

It was a Fujitsu, don't remember the model. Minimal set of ports, 1/2 in thick. Came with a very cool docking station that had a full set of ports & a CD-ROM drive. It was actually lighter than the 1st gen Air (had one of those as well....), with roughly similar battery life (2hrs if you were lucky). Not as thin and all plastic, 'tho.

Apple is not the first one to build a minimalist light laptop, although I had a PowerBook Duo back in the day that came pretty close - it was replaced by the Fujitsu, then by an Acer of similar spec, but with a 14" screen...

Re: 9 hours of unplanned downtime in 12 years is pretty good

For a relatively cheap hosting, it's about as good as it gets. Even Amazon's vaunted redundant 'cloud' isn't as good.... Besides, a wealth of sites with vastly more resources went down as well, from Gizmodo to the Huffington Post, so I think we've done very well with our meager resources.

The reality of infrastructure is that almost no one needs 'five nines' and even fewer people are willing or in a position to pay for it. It's a nice marketing term, but five-nines of the people who throw it around have zero need for it.

Besides, in the modern world, you would want to achieve high-reliability through application architecture as well as good infrastructure. In our case, we could have failed over to a backup datacenter on the West coast, but the question was how long the NYC datacenter would be out, and if it was a good use of our time to migrate everything (it's a cold standby). In our case, the answer is no as we risked some data sync issues and our downtime was during the dead of night for all our customers (and they were all aware of the issues).

Had it not come back up before end-of-day today, we might have considered differently. It's still touch & go, so we might migrate after all.

Re: The building in not a dedicated colo

Everything came back up (as expected) about a 1/2 hour ago.

I've used this same facility for the last 12 years across 4 different companies and the only other unplanned downtime was a failed switch for two hours about 6 years ago.

This particular outage was a total of 7 hours during what is being described as a 'catastrophic' storm. Overall, I would say that 9 hours of unplanned downtime in 12 years is pretty good.
