If you hit Cmd-W a bunch of times to close all open files, ST2 should not close the project window if there are no more files open. In other words, Cmd-W should close files, but not the project window.

Hi,

My computer does not recognize the sublime text installer dmg :/
Seems to be broken.

In the most recent build a feature was added - "Clicking on a background window will bring it to the front only, and not change the selection". I understand the use of this with multi-windows open, but now it's painful to place the cursor after searching for text. For example, I hit cmd + f to search for text in a document, then I have to click in the window twice to place the cursor (once to activate window, once to place cursor).

Perhaps this behaviour shouldn't happen from the find window (considering find changes the selection anyway), or there should be a toggle in preferences.

It'd be good if like TextMate I could just run the script I'm working on. Maybe this exists but I can't find it, in this case it'd be good to have it more prominent.

CMD + R is a habit of running to test my script works. Unlike TextMate though it'd be awesome if when I do this Sublime asks me for program arguments before running the program.

Caltech researchers have developed a new laser that could send data over the Internet backbone up to 20 times faster.

The breakthrough culminates five years of work by researchers working under Amnon Yariv, professor of applied physics and electrical engineering at Caltech. The current study was led by postdoctoral scholar Christos Santis and graduate student Scott Steger.

While laser light is capable of carrying vast amounts of information, it needs to be as spectrally pure, or as close to a single frequency, as possible. The greater the spectral purity, or coherence, the more information the light can carry.

Researchers have worked for decades to develop a laser that comes as close as possible to emitting a single frequency, but today’s global optical-fiber networks are still powered by a laser known as the distributed-feedback semiconductor (S-DFB) laser, which was developed in the mid 1970s in Yariv’s research group.

That laser’s unusual longevity stemmed from what, at the time, was considered unparalleled spectral purity. The laser’s increased spectral purity directly translated into a larger information bandwidth of the laser beam and longer possible transmission distances in the optical fiber. The result was that more information could be carried farther and faster than ever before.

That unprecedented spectral purity was a direct consequence of the incorporation of a nanoscale corrugation within the multilayered structure of the laser, which acted as an internal filter that discriminated against “noisy” waves contaminating the ideal wave frequency.

Despite the successful 40-year run of the old S-DFB laser, its spectral purity no longer satisfies today’s fast-growing demand for bandwidth.

“What became the prime motivator for our project was that the present-day laser designs — even our S-DFB laser — have an internal architecture which is unfavorable for high spectral-purity operation. This is because they allow a large and theoretically unavoidable optical noise to comingle with the coherent laser and thus degrade its spectral purity,” the researchers told Caltech’s Jessica Stoller-Conrad.

The old S-DFB laser consists of continuous crystalline layers of materials known as III-V semiconductors, which convert into light the applied electrical current flowing through the structure. Once generated, the light is stored within the same material.

Since III-V semiconductors are also strong light absorbers, which leads to a degradation of spectral purity, the researchers wanted to find a different solution for their new laser.

So they developed a new, high-coherence laser that still converts current to light using the III-V material, but stores the light in a layer of silicon, which does not absorb light. Spatial patterning of this silicon layer causes the silicon to act as a light concentrator, pulling the newly generated light away from the light-absorbing III-V material and into the near absorption-free silicon.

This higher spectral purity offers a 20 times narrower range of frequencies than possible with the S-DFB laser, something that could be particularly important for the future of fiber-optic communications.

Originally, laser beams in optic fibers carried information in pulses of light – data signals were impressed on the beam by rapidly turning the laser on and off, and the resulting light pulses were carried through the optic fibers. However, to meet the ever-increasing demand for bandwidth, communications system engineers are now adopting a new method of impressing the data on laser beams known as coherent phase communication, which no longer requires this “on-off” technique.

In coherent phase communications, the data resides in small delays of just a tiny fraction (10-16) of a second in the arrival time of the waves. These delays can accurately relay the information even over thousands of miles, the researchers said.

The digital electronic bits carrying video, data, or other information are converted at the laser into tiny delays in the otherwise steady light wave. However, the number of possible delays, and thus the data-carrying capacity of the channel, is fundamentally limited by the degree of spectral purity of the laser beam.

Yariv and his team concluded that while absolute purity can never be achieved due to limitations set forth by the laws of physics, they have nevertheless tried to come as close as possible to achieving this goal.

A paper about the work, entitled “High-coherence semiconductor lasers based on integral high-Q resonators in hybrid Si/III-V platforms,” was published last week in the journal Proceedings of the National Academy of Sciences.

In addition to Yariv, Santis, and Steger, other coauthors include graduate student Yaakov Vilenchik, and former graduate student Arseny Vasilyev (PhD, ’13).

This idea is implemented in the jetBrains products, and it turns out to be super helpful. Basically, you can copy up to five things and then press Ctrl+Shift+V to bring up a small dialog to pick which of the last five things you copied for you to choose which one should be pasted.

Alt+e , t  /  Alt+e , c  /  Alt+e , p  -  I rely heavily on these functions for quick and 'sure' cut/copy/paste in all programs that I use.  In sublime, these defaults are not 'the way' and custom hot-keys make the edit menu not appear at all :(  Please bring back the default functions of these keys as I highly doubt that anyone uses the 'new' methods.

would be great to have a shortcut for jumping to a parent class of the current buffer. In langs that don't have implementation/header file types it would be a great help

With beta 2095 on Mac, it looks like Wrap Paragraph at Ruler always wraps at 80 columns, regardless of what my ruler is set to.

(Minor side note: "Paragraph" is capitalized in the Wrap menu for "Wrap Paragraph at Ruler" but lowercase for all of the other items in that menu.)

Possibly: make entering ~ or / as the first character trigger non-project.
