Ambition metrics seem to be evolving. Whatever happened to Victor Frankenstein ambitious? Or Craig Venter ambitious? Has creating new life become less ambitious since the story of DNA was unravelled? Turns out there are arithmetic problems that are harder that these things.

I have seen enough CRM projects fail to consider them to be hard. For all we know consumer-side CRM might be really hard. After all, it involves human relations. Perhaps someone will come along one day and prove that creating the perfect CRM system involves solving a really hard arithmetic problem.
Incredibly slow download right now. The Lion onslaught must be in full effect. I pulled Lion in about 15 minutes this morning. Xcode is estimated at about an hour and a half.
illegal? i hope someone goes to jail for this!!!
Startup Karma: The More You Give, The More You Get
"One way to get C-like performance is to use C via JNI for key sections of code. If you want to avoid using C or JNI there are still ways you can get the performance you want."

JNI has huge latency. Write code in Java to get "C-like" performance.

"One area Java can be slower is array access. This is because it implicitly does bounds checking."

Which gets optimized away by hotspot.

"However this doesn't mean you can't pre-allocate your objects, use Direct ByteBuffers and Object recycling techniques to minimise your object creation."

Please don't write your own object pools, this isn't 1995.
Redolf is a simple online music service with playlist support.
You can search & play songs, add songs to playlist and share a song or entire playlist with others.
Finally, I wish more places would do this. Not to mention airlines. I know a few places that make it just very child unfriendly, but they don't have the balls to just say it outright. I don't see the issue either; then you don't go there if you want to go with kids; there are enough restaurants, no clue why anyone would turn this into an issue.
Corporate Debt Safer Than Treasuries
If the U.S. is downgraded, there could be a handful of companies that would boast a higher credit rating than the U.S. Four major companies (Microsoft, Johnson & Johnson, Exxon and Automatic Data Processing) have a AAA rating from both S&P and Moody’s. Could corporations like these become the go-to safe haven for investors in distressed times? Based on the credit default swaps, these companies have a lower chance of default than the U.S. The swaps currently imply 0.75% cumulative chance of default for the U.S. over the next 5 years. Compare that to MSFT (0.7%), Exxon (0.5%) and J&J (0.35%). These cash rich corporations do not suffer from the political logjam currently plaguing our country’s economy. The U.S. runs the risk of not using its available resources to pay off its obligations, but there is no concern that these companies will miss coupon payments or principal repayments simply because they don’t want to.

Yep. We met with them and gave them a ton of feedback. Looking forward to their next revision.
Casey Reas on Code and Art
a) They have, ATI implemented Brook+

b) GPUs are still first and foremost special purpose hardware. Few applications are benefitting from moving all your data over to your graphics memory, pushing it through a broad but slow pipe and copying everything back to your CPU. You need to pull out all the low-level stops to get the most out of the hardware, which means dealing with really low-level libraries. CUDA has something like 7 types of memory locations you can declare for your data to sit in and some are calling OpenCL too abstract.
It's in the Lion features page, so it's probably there. But not all models are supported:

AirDrop

supports the following Mac models:

* MacBook Pro (Late 2008 or newer)
* MacBook Air (Late 2010 or newer)
* MacBook (Late 2008 or newer)
* iMac (Early 2009 or newer)
* Mac mini (Mid 2010 or newer)
* Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)
Given that Scala targets the JVM, you are going to have to use the same tricks and probably a few others.
Yeah, these might all be valid reasons to use surrogate keys. I'm not saying there are none, just that always using one often leads to design mistakes.

Incidentally, part III of the keyvil blog posts talks about reasons to use surrogates :)

As always, nothing's black or white, sometimes surrogates are OK, sometimes they're not. But I see schemas abusing surrogates much more often than schemas abusing natural keys...
Should have known that before I clicked 'buy'. Glad I own Apple shares so I can make a profit from my unnecessary purchase.
What are you looking for in your engineers? I read about your company and looked over the site the UI you all have developed is very impressive!
People Installing Lion
As someone who lived in China for seven years and is presently traveling around India (also having done business across Asia in a bunch of countries, and traveled to yet more) all I can say to this is "yes".

India + China = huge chunk of world, making many things.

Almost no legacy fixed-line infrastructure.

Low prices.

I'm online via 2G in the middle of nowhere and it works. And you know what, once you get past the "I can't watch youtube or kickstarter videos" issue, it's actually great. When the power goes out, I stay online, because I'm using a laptop and wireless.

Also, space is at more of a premium in Asian cities, so desktops make slightly less sense for that reason.

In China, the domestic wireless infrastructure is amazing because the government just said "we do this, now" and it happened. In 2001 when I first moved there, you'd see consultants flown in from the west to install, configure and maintain these systems. Now China themselves are world leading manufacturers and servicers for most of the critical infrastructure components (Huawei, etc.), and selling it to everyone else (eg: most of Africa).

Asia is amazing. I think that more people should leave the west for a few years and check it out.
I switched from JungleDisk to Backblaze a year ago and haven't looked back. BB is amazingly fast and painless to use. On top of that the cost is insanely cheap in comparison to using AWS (which Jungle Disk uses).
I wonder if there's an age difference thing here. I'm unusual for my early twenties (AFAICT) in that I have several numbers in my head (including most of my college phone numbers, original home phone number, etc). Most of my friends are helpless without their cell.
I prefer viewing and searching for code on github to any other site I've found, so I got a micro account to support the site (and keep a few repos private until I am ready to make them public).

Plus github hosts my blog for free and without headaches, so that's worth the couple bucks a month on its own.
Good. There are few things that ruin my dining experience faster than a bunch of misbehaved, screaming children. I'd go to this restaurant for no other reason than this policy if I were in the area.
Yeah, they've blurred the line a little bit. But the canonical patent troll is one that hasn't created anything, just capitalizes someone else's patents... and Myhrvold doesn't really fit into that category.

> so why have they crippled it so horribly in this release?

I'm guessing it's because they decided to put full-screen apps on their own space (sensible), but there's nothing else you can put in there since the application essentially is the space (if you shut down the full-screen mode, the application goes back to its original space).

Basically, lack of foresight: they built full-screen for small-screen machines (e.g. the Air) and it's just broken for multi-screen.

Thanks for coming! It's been great meeting all of you over the last two years at H&F.
You're right here. Every person that sees the money flowing and focuses on that will lose out on actually making something people want.

It's easy to look at a startup space and see which companies get it, and which are there because the probability of success (due to focus on that particular market from acquirers and VCs, market size, etc.)

This article is kind of scary because people are taking the approach that entrepreneurship is something that everyone can do. I think everyone can try (and would advocate for it) but this type of attitude normally precedes many failures.
Glad to see it's back to free. Now I wish I didn't waste that $5...
I have yet to find equivalent web apps which offer equivalent security and poweruser capabilities.
This. When I read the article, I was actually surprised that he didn't want his sales team to generate a smaller overall revenue, distributed over the month - I assumed that the distribution would drive down costs and lead to greater profit.

One thing that I think would have worked better is ask his sales team "why do most of our sales come at the end of a quarter?"
The battery life is 40% longer on the 13", which to me is enough to swing the balance. The size is only about an inch different in two dimensions and 1/2 pound.

I have a previous generation 13" and I find I use the SD port often, which is missing on the 11".
Is this the way you want your sci-fi?
Xcode 4.1 has now been released in MAS.
All good OS's try to use all the RAM availible (within certain limits of course). My RAM is almost always at 80% usage and above even with just a couple of lightweight applications running.

I found this video to be quite moving. It's something you already know but sometimes forget.
ARGH. I'm still bitter over the introduction of Spaces in the first place—a crappy implementation of virtual desktops that nevertheless drove all the third-party versions out of business—and now they cripple their already-weak version further?

Over and over in this review I'm seeing Steve Jobs's message come through loud and clear: "You should be on an iPad. We're going to make Macs as much like iPads as we can, even when this makes no sense and observably degrades productivity and user experience. If you're still somehow holding on to your non-iPad existence, we don't give a shit."
Github would be a networking service for developers through the software code. Gitorious seems not to have such community, I guess. A lot of open source projects on github attracts those people.
Burning A Lion Boot Disc
Similarly if you start measuring LOC (lines of code) on your developers and rewarding or penalizing as such. You are guaranteeing that the number of LOC increase. Same applies to things further up in the stack - # bugs fixed, # tickets closed, etc.
Real-money gambling historically generates over 100X more ARPU than typical social gaming revenue streams, so even with that rev split, game developers stand to make much more money than they currently do. Also, unlike other platforms that game developers are sharing their revenues with (iOS, AdMob, etc.), Betable is processing all of the transactions and resolutions related to real-money gambling play. In other words, Betable is much more hands on with helping the developer make money.
Let the Lion roam – wait two days to install
What is next: a restaurant without Asians? or without gays? or without Muslims? or without senior people? There are plenty of other restaurants that would accept them, I don't see why they would complain if just a few refused them. Or maybe a restaurant that would not accept just you!
I reinforce this comment. The title "When Employees Misinterpret Managers" at best very weakly implies that the managers are doing something. It plainly states, in normal English, that employees did something (they misinterpreted) to managers. Only by the most convoluted thinking could you remove that plain meaning and substitute in "managers gave instructions excessively prone to misinterpretation" or something similar. `bryanlarsen`'s point is absolute bullshit.

Now: reading the article, that does indicate that it's the managers' fault, and it's a bang-up job of doing that. But the headline - oy!
Millions more developers can now play with it at work. Granted they could have been using a VM up to now but for many their machine can't handle a Java based IDE (Eclipse, Netbeans) within a VM.
Note that the Airs have much more manageable screen real-estate than the 13" MBP: the 11" already has a higher resolution than the 13" MBP, and the 13" MBA has the same resolution as a non-HD 15" MBP.
Someone didn't get your humor, apparently. For those that didn't catch it, this isn't illegal at all. It's simply not allowed by the 'rules'.

The pithy comment above was a clever poke at using the word 'illegal' to describe something that wasn't illegal at all.

What is the max user processes ulimit set to?
While that certainly is a direction that things could go if you took this to an absurd level, places can already ban kids buy doing lots of things related to alcohol and smoking in many jurisdictions. Doing it outright doesn't really change much other than the liquor license requirement.

Not to mention: This isn't a ban on children, merely children under 6.
I'm keenly interested to see if this provides a visual indication of markup or layout clutter/complexity. That would be nice for sniffing out UI design smells, particularly in big enterprise portals.

Sadly, when I launch the tool it seems to create an overlay that prevents input to the page but doesn't show anything. Not blank, just invisible. I can close the overlay and keep using the page. But, I can't see anything. Hopefully I can figure that out.

I plan to use this for a side-by-side comparison of my product, Oracle web UIs (I'm scared), some nicely-designed and clean sites and some prominent web apps like Amazon or Backpack. Might be a useful tool for me on the "Marketecture" side of things.

They are getting a huge amount of free press. I have read at least two other stories and seen it on tv. That, combined with customers who approve of the ban will significantly outweigh the losses from kids/young families.

"...or you’ve installed a hard drive without OS X, for example — Internet Recovery takes over automatically"

Could a dual boot system (Lion + Ubuntu) be confused with "hard drive without OS X" and be taken over by the Lion Recovery automatically?

Hope this doesn't means that only OS X should be installed in a Mac.

I have to admit, at first i thought there was no way something like this could ever be done. It seems these guys have it figured out though. I'm sold.
Automatic Reference Counting (as in OS X Lion)
As a (hopefully) responsible father, I don't see why anyone would have any logical reason to complain about this idea. Let the owner run his business the way he wants, and if you don't like it then tough. There are plenty of other restaurants to eat at where it won't be a huge faux pas if your kid misbehaves.

I'd just hope that the staff makes the policy very clear because this is definitely outside the cultural norm. I'd be REALLY mad if I made reservations for something like a nice Father's Day brunch, showed up and was told that I could eat but my daughter would have to wait outside.
For servers, memory is usually the long tent pole. For me it boils down to:

* Use less memory.

* Don't use a lot of threads.

* Use fewer objects.

Worst-case GC is a big issue. For just a 2 GB heap you are looking at up to 7 second GC pauses with the Java 6 collector. You can use concurrent GC but it adds significant CPU and memory overhead. Direct buffers don't live in the heap so they don't contribute to GC time.

Threads in Java are extremely heavyweight in memory, if not in CPU. A rule of thumb is about 1 MB per thread. You can make it better by decreasing the stack size and/or using 32-bit addresses.
For most users no, but for $30 its kind of hard to make excuses not to upgrade.

I'm a huge fan of the ASLR and sandboxing changes so security wise there are good reasons to upgrade.
After my experience in not using them for a large schema, using an int pk is pretty much a default decision for me, unless the table's PK is meaningful compared to another table like an association table. Doing big data migration jobs where the primary keys have to change is very painful. An identity-map ORM like SQLAlchemy is keying everything on primary key - SQLA supports mutable PKs and cascading updates (both via the DB, as well as in memory if you're on sqlite/MyISAM) fully, but the changing in-memory identities is fundamentally painful to deal with when you're shoveling around a lot of data and mutations.

I have given up on TM because it chews up my external drives at an alarming rate. I have had three hard drives die in the last 2 years because of TM. My other drives of the same brand that didn't have TM are just fine still. Either I have extremely bad luck with WD drives, or time machine is just not a reliable backup mechanism (I'm inclined to think the latter). Plus, the drives have to be HFS formatted which is also a con for me (that I am willing to live with in exchange for a reliable backup solution).

Is anyone else experiencing these kinds of problems with TM?

I have a neighbor who manages Juniper support engineers. These engineers are typically working onsite at Juniper customers. He has been almost constantly recruiting new support engineers (who seem to either have CCIE certs or a similar experience level) for probably 18 months.

Since this recruiting is primarily for new customers, I would guess that Juniper is doing quite well competing against Cisco.
What's the RAID config of these boxes? 45 drives, 4 controllers, and a 16TB volume limitation from ext4. Please share if you know!

I wouldn't lump Cheryl Yeoh (the person you're quoting) in with 'drone lambda' or 'type-A square'. She's very driven, and has made a hell of a lot more progress with CityPockets than I would've expected.
That is indeed the problem.

It is perfectly legal and acceptable to throw someone out if they or their party are being disruptive.

Banning them simply on some artificial criteria is a bad idea.
Dataflow means a language or machine who's execution is driven by the availability of data.
In a dataflow computational model you do not have the concept of memory.

In a Von Neumann architecture (viz. your current CPU) execution is determined by the previous instruction. Data is stored in a global, randomly accessible memory space.

Synchronizing two data streams in dataflow is just a matter of having an instruction with two inputs. The very semantics of your machine tells you the node's instruction will only trigger when both its inputs are available.

Critical systems with the problems you described are often written in dataflow languages for exactly these reasons. Citing wikipedia:

Lustre is a formally defined, declarative, and synchronous dataflow programming language for programming reactive systems. [...] It is now used for critical control software in aircraft, helicopters, and nuclear power plants.
While I have not read that book it looks fairly biased. And as they say it's easy to lie with statistics but let's compare the fact that "Men win more custody battles" with:

"Despite changes in the law and social custom, custody arrangements remained remarkably stable over the past three decades. National estimates in the 1970's and 80's indicated that women had sole custody of the children approximately 85% of the time, and men retained sole custody 10% of the time, with the remaining 5% spread over a variety of custody arrangements, including grandparent, split or joint custody. More recent data sets indicate that father custody figures may be closer to 15%. " http://www.stanford.edu/group/psylawseminar/Child%20Custody%...

It goes further as said as joint custody became an option an increasing number of family's took that option. This suggestion a large scale imbalance where large numbers of men would like to have more custody but they are far less likely to get it.
