Although the H-1B visa technically allows the employees to change jobs, that's not the way it happens in practice. Unless you already have a second employer lined up (who had already gone through the lengthy legal process to be able to hire you), leaving an H-1B job pretty much means deportation.

That's all well and good.. but we could do even better by abandoning the whole foursquare concept entirely and just going places for the hell of it. Not everything in life needs to be turned into a badge or achievement. I am surprised that the whole "checking in" concent limped on this long considering its clunkiness and "tacked on" factor.

Comment Odd thing about the HW teardown - the rest of it (Score 1) 492 492

Shennanigans regarding Engadget vs Gizmodo (bar in Redwood City vs bar in Cupertino) aside, there is an interesting question left:
Where is the rest of the hardware teardown? All we are given is a single photo of a ribbon cable inside the phone, but none of
the shots of the chipset, PCBs, layout, etc.

More interesting still is the fact that the one (uninteresting) photo of the disassembly is named open13.jpg, implying that there
was an entire series of these shots, including juicy things like the processor, etc.

Why are these photos missing? Careless omission, or is something else going on here?

Just my $0.02.

Comment Scam site is google-ranked higher than google's. (Score 1) 291 291

Well... It appears that the first google hit for 'chrome add-ons' links to mychromeaddons.com
This site is made to look like google's, but is LITTERED WITH ADS. The whois information reveals it's a third-party site.
The OFFICIAL chrome add-on site also does list an AdBlock extension, but something is fishy about it. When trying to install it, Chrome warns that "this extension is trying to access your data on api.flickr.com." What the hell?

We'll see if and how Google will try to combat these issues...

Would apple seriously ever consider USING such a thing? It would be most terrible. But of course, apple is so obsessed with its image that I doubt they would ever employ this technology.
Of course, having a patent on this atrocious god-awful piece of work will effectively prevent other, less image-conscious vendors from doing similar things, which might mean (could it be?) less intrusive advertising on other platforms.

Comment Learn Eagle (Score 1) 262 262

Get Eagle. It's free and there are a lot of part libraries out there. It's quite backward, but you will soon learn that most electronics CAD tools are. I guess there isn't all THAT much overlap between ECE and HCI people... Have Eagle produce a Gerber file and then send it off to your favorite board house. Happy routing :)

Comment Re:I can has Multiprotocol Label Switching? (Score 1) 690 690

In a connection-oriented system, it is easier to provide QoS (guaranteed bandwidth, delay, etc) because the routers know which packet belongs to which flow. Thus, the routers can maintain per-flow bookkeeping, and drop any packets from a connection that is exceeding its allocated bandwidth. At the same time, the network is told the amount of requested bandwidth per connection ahead of time. Since each router knows its available bandwidth (and the bandwidth reserved so far), each router can definitely answer whether or not it can support X amount of extra bandwidth. This way, a proper path can be negotiated through the network, at connection time, such that every node along the way can handle the requested bandwidth, delay, jitter, etc.

As for security, knowing your path to someone else isn't the issue. The issue is being able to manipulate that path (and others) at will. There are a number of hijacking, redirection, man-in-the-middle, etc attacks that rely on issues within the way IP packets are routed. In a circuit-switched system, like MPLS, the control plane basically lives in its own separate world and is essentially decoupled from the data plane (like with the phone network). That is, forwarding decisions are made based on an extra attribute connected to every packet (the so-called label ID) and not on some user-accessible field within the data itself. The only time that the user has access to this attribute is when specifying the "connection ID" associated with each outgoing packet, but that is strictly an agreement between the user and his serving router and has little relation to the upstream label tables.

Well, of course we need to specify the destination address. In the MPLS case, we would signal the router serving us that we wish to talk to a certain address, and the router would send back a label ID that corresponds to that connection. (While the destination addresses are global, the label IDs can be reused per pair of devices, but that is besides the point). At this point, the path is set up and cannot really be "messed with" and you reference it by the label ID.
The security benefit is that the routing mechanism is invisible to the end user. He needs to specify the destination and the rest of the connection is up to the network.
Of course, the other benefits are efficiency and traffic engineering. With the network being aware of the actual connections (unlike with TCP, where packets are essentially disjoint from a router's point of view), it is relatively easy to provide features like bandwidth reservation, QoS guarantees, etc. And the actual switching process for circuit switching is a lot more efficient. It is far easier for a router to perform a label lookup and then push/pop/swap labels than it is to carry out the longest prefix match lookup. In fact, such technology is already used internally by some ISPs, but it is not available globally or end-to-end.
