• How do I calculate percentiles with python/numpy?

  - by Uri

  Is there a convenient way to calculate percentiles for a sequence or single-dimensional numpy array? I am looking for something similar to Excel's percentile function. I looked in NumPy's statistics reference, and couldn't find this. All I could find is the median (50th percentile), but not something more specific.

• uses for dynamic scope?

  - by Stephen

  Hi, I've been getting my hands wet with emacs lisp, and one thing that trips me up sometimes is the dynamic scope. Is there much of a future for it? Most languages I know use static scoping (or have moved to static scoping, like Python), and probably because I know it better I tend to prefer it. Are there specific applications/instances or examples where dynamic scope is more useful?

• Why make short and long-lived objects a difference in garbage collection?

  - by DR

  I've often read that in the Sun JVM short-lived objects ("relatively new objects") can be garbage collected more efficiently than long-lived objects ("relatively old objects") Why is that so? Is that specific to the Sun JVM or does this result from a general garbage collection principle?

• TCPDF Auto Page Break Not Working if Widths set

  - by kenitech

  I have a very specific 2 column layout I'm trying to set up for a client using TCPDF. AutoPageBreak works fine if you're sending text to a page with writeHTML and multiCell at the default width of the page. When I set a narrower width for a multiCell TCPDF doesn't know when to page break. This is driving me insane. Here's super simple example set up here: http://www.artworknotavailable.com/temp/tcpdf/

• Easy way to convert and copy a solution to VS 2010

  - by TheSean

  We have a VS2005 solution and I want to convert it to VS2010. I figured an easy way to keep the old solution around (for other developers) is to create new sln and proj files specific to 2010. I hoped that the conversion wizard would do this easily but it doesn't seem to. Anyone know an easy way to copy all .sln and .csproj files, then convert to VS2010?

  - by wls

  I have multiple language packs in my NSIS installer, using the MUI2 interface. Now I try to select the language pack, which is installed by the "Typical" installation type according to the user's chosen setup language. My problem is, that I can't figure out, how to get the user's language selection.

• Verilog linting tools?

  - by mrflibble

  What are your favorite linting tools for verilog? I am currently looking for a good verilog linting tool. And preferably one that can be configured to either handle or ignore certain vendor specific primitives like LUT's, PLL's, etc. I recently tried verilator-3.810, but out of the box it needs a little help with the primitives. So what (linting) tools do you use to deal with the not-so-strict syntax of verilog?

• ListView ToolTip only in First Cell - VB.NET

  - by Louise

  I'm adding a ToolTip to a ListViewItem. However, the ToolTip only shows up when the user hovers over the first cell in the row to which the ToolTip has been applied. MyListViewItem.ToolTipText = "Important Message" The only other code I have related to ToolTips is this: MyListView.ShowItemToolTips = True Any idea how I can make the ToolTip show up on a specific cell in a row, or even the entire row? Thanks.

• How to decide on what hardware to deploy web application

  - by Yuval A

  Suppose you have a web application, no specific stack (Java/.NET/LAMP/Django/Rails, all good). How would you decide on which hardware to deploy it? What rules of thumb exist when determining how many machines you need? How would you formulate parameters such as concurrent users, simultaneous connections and DB read/write ratio to a decision on how much, and which, hardware you need? Any resources on this issue would be very helpful...
