Hi, I''m trying to execute something like this method in a model: def self.sql_for_rankings() sql = "SET @counter:=0;" sql << " SET @counter:=0; SELECT *, @counter:=@counter+1 AS rank FROM testscores. " find_by_sql(sql) end Where the new rank column is a kind of autoincrementer inside of

There have been a lot of responses. I'll try to summarize the thread and respond to some of the questions/feedback. Summary ======= 1. We should teach GlobalDCE to strip out instrumented functions which the inliner cannot delete. 2. Sean suggests adding metadata to loads/stores of counters to convey that they do not alias normal program data. I'm not familiar with AA, but

Hi All, I have a questions about associative list mappings in R, and if they are possible? I have data in the form show below, and want to make a new 'bucket' variable called combined. Which is the sum of the control and the exposed metric values This combined variable is a many to many matching as values only appear in the file if they have a value > 0. conversion.type filteredID

Hi, The current design of -fprofile-instr-generate has the same fundamental flaw as the old gcc's gcov instrumentation: it has contention on counters. A trivial synthetic test case was described here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-October/066116.html For the problem to appear we need to have a hot function that is simultaneously executed by multiple threads -- then we will

I am acquiring some sampled data that is time-stamped (with a POSIXct). Some of the data is in the form of "counters" -- that is, what is interesting isn't value of a given counter at a given time, but the change in the counter from one sample to a later one. As the counters are only incremented, they would be perceived to be monotonically increasing -- ideally. Unfortunately, the

Hi, I'd like to add a new pass to LLVM which removes redundant profile counter updates. The goal is to speed up code coverage testing and profile generation for PGO. I'm sending this email out to describe my approach, share some early results, and gather feedback. Problem Overview ================ A profile counter is redundant if it's incremented in exactly the same basic blocks

Hello, Our goals for the code coverage BoF (10/19) were to find areas where we can improve the coverage tooling, and to learn more about how coverage is used. I'd like to thank all of the attendees for their input and for making the BoF productive. Special thanks to Mandeep Grang, who volunteered as a mic runner at the last minute. In this email I'll share my (rough) notes and outline

Googling for this finds me a ton of stuff that doesn't actually do what I'm looking for. I want a simple hit counter cgi script of some kind that will increment a counter on every page load but I want to access the counter from a different page. In other words, I don't want to have a visible hit counter on the webpage itself. I want to have a different webpage that will show me the

I''m working on a RESTful app, and I''ve hit a snag. Here''s a simplified example of the problem. (Excuse me if this example code isn''t strictly correct; I''m typing from memory.) Suppose I have a table which models a simple counter. It has a single column, "count": class CreateCounters < ActiveRecord::Migration def self.up

Hi everybody! I've a large dataset, about 2 Mio entries of the format which I would like to import into a frame: <integer><integer><float><string><float><string><string> Because to the huge data amount I've choosen a binary format instead of a text format when exporting from Matlab. My import function is attached below. It works fine for only

I have an application where I need to send outbound prerecorded messages. The Asterisk "call file" process works fine if I am sending the call via SIP or IAX, but not via ZAP over a PRI channel. The destination device (my cell phone) never rings. The only unusual thing I see is on the fifth line of the "full" log, below, "channel.c: Don't know what to do with

Hi all, Does ENUMLOOKUP can query multiple DNS servers without having to replicate the same code in which the only thing replaced is the server? If I use ENUMLOOKUP(${exten}), Asterisk will parse enum.conf file to find the list of DNS servers in order of preference to be queried, but, I pretend to use something like this: ${ENUMLOOKUP(+${ARG1:2:},sip,c) which does not seam to care about
