• Sqlite3 "chained" query

  - by Arrieta

  I need to create a configuration file from a data file that looks as follows: MAN1_TIME '01-JAN-2010 00:00:00.0000 UTC' MAN1_RX 123.45 MAN1_RY 123.45 MAN1_RZ 123.45 MAN1_NEXT 'MAN2' MAN2_TIME '01-MAR-2010 00:00:00.0000 UTC' MAN2_RX 123.45 [...] MAN2_NEXT 'MANX' [...] MANX_TIME [...] This file describes different "legs" of a trajectory. In this case, MAN1 is chained to MAN2, and MAN2 to MANX. In the original file, the chains are not as obvious (i.e., they are non-sequential). I've managed to read the file and store in an Sqlite3 database (I'm using the Python interface). The table is stored with three columns: Id, Par, and Val; for instance, Id='MAN1', Par='RX', and Val='123.45'. I'm interested in querying such database for obtaining the information related to 'n' legs. In English, that would be: "Select RX,RY,RZ for the next five legs starting on MAN1" So the query would go to MAN1, retrieve RX, RY, RZ, then read the parameter NEXT and go to that Id, retrieve RX, RY, RZ; read the parameter NEXT; go to that one ... like this five times. How can I pass such query with "dynamic parameters"? Thank you.

• Data in linux FIFO seems lost

  - by Utoah

  Hi, I have a bash script which wants to do some work in parallel, I did this by putting each job in an subshell which is run in the background. While the number of job running simultaneously should under some limit, I achieve this by first put some lines in a FIFO, then just before forking the subshell, the parent script is required to read a line from this FIFO. Only after it gets a line can it fork the subshell. Up to now, everything works fine. But when I tried to read a line from the FIFO in the subshell, it seems that only one subshell can get a line, even if there are apparently more lines in the FIFO. So I wonder why cannot other subshell(s) read a line even when there are more lines in the FIFO. My testing code looks something like this: #!/bin/sh fifo_path="/tmp/fy_u_test2.fifo" mkfifo $fifo_path #open fifo for r/w at fd 6 exec 6 $fifo_path process_num=5 #put $process_num lines in the FIFO for ((i=0; i<${process_num}; i++)); do echo "$i" done &6 delay_some(){ local index="$1" echo "This is what u can see. $index \n" sleep 20; } #In each iteration, try to read 2 lines from FIFO, one from this shell, #the other from the subshell for i in 1 2 do date /tmp/fy_date #If a line can be read from FIFO, run a subshell in bk, otherwise, block. read -u6 echo " $$ Read --- $REPLY --- from 6 \n" /tmp/fy_date { delay_some $i #Try to read a line from FIFO read -u6 echo " $$ This is in child # $i, read --- $REPLY --- from 6 \n" /tmp/fy_date } & done And the output file /tmp/fy_date has content of: Mon Apr 26 16:02:18 CST 2010 32561 Read --- 0 --- from 6 \n Mon Apr 26 16:02:18 CST 2010 32561 Read --- 1 --- from 6 \n 32561 This is in child # 1, read --- 2 --- from 6 \n

• regular expression to remove original message from reply mail using in java ?

  - by ravi ravi

  In my forum, users can reply through email. I am handling mails from their reply. When they are replying the original message getting appended. I want to get only the reply message not the original message. I have to write regular expression for gmail & hotmail. I written regex for gmail as follows : \n.wrote:(?s).--End of Post-- It is removing the original message except date. I want to remove the date also. before removing the original message : " hi 33 On Tue, May 11, 2010 at 4:18 PM, Mmmmm, Rrrrr wrote: The following update has been posted to this discussion: test as user 222 [$MESSAGE_SIGNATURE_HEADER$] --End of Post-- " When I use the above regex it is filtering as follows : " hi 33 On Tue, May 11, 2010 at 4:18 PM, Mmmmm, Rrrrr " Here i want only the actual message 'hi 33' not that date. How can I filter the date using above regex? Also I need regex for Hotmail also. I appreciate for any reply. Thanks in advance.

• cfchart ignores my scalefrom value

  - by Monte Chan

  Hi all, I have the following codes in my page. The style variable holds the custom style. <cfchart chartheight="450" chartwidth="550" gridlines="9" yaxistitle="Score" scalefrom="20" scaleto="100" style="#style#" format="png" > <cfchartseries query="variables.chart_query" type="scatter" seriescolor="##000000" itemcolumn="MyItem" valuecolumn="MyScore"/> </cfchart> Before I begin, please go to http://www.monteandjanicechan.com/chart_good.jpg. This is how I want my report to come up. On the x-axis, there will always be three items as long as at least one of them has values. If an item does not have any values (i.e. 2010), there would not be a marker in the chart. The problem occurs only when only one item has value. Please see http://www.monteandjanicechan.com/chart_bad.jpg. As you can see, 2008 and 2010 do not have any values; y-axis is now scaled from 0 to 100. I have tried setting one of the items (ex. 2008) a value of 0 or something off the chart; it would scale according to this off-the-chart value and the 2009 value. In short, I have to have at least two items with values between 20 and 100 in order for cfchart to scale from 20 to 100. My question is, how can I correct the issue so that cfchart would ALWAYS scale from 20 to 100? I am running CF9. Thanks in advance, Monte

• How to set default date in date_select helper in Rails

  - by brad

  I'm trying to set up a date of birth helper in my Rails app (2.3.5). At present it is like so. <%= f.date_select :date_of_birth, :start_year => Time.now.year - 110, :end_year => Time.now.year %> This generates a perfectly functional set of date fields that work just fine but.... They default to today's date which is not ideal for a date of birth field (I'm not sure what is but unless you're running a neonatal unit today's date seems less than ideal). I want it to read Jan 1 2010 instead (or 2011 or whatever year it happens to be). Using the :default option has proven unsuccessful. I've tried many possibilities including; <%= f.date_select :date_of_birth, :default => {:year => Time.now.year, :month => 'Jan', :day => 1}, :start_year => Time.now.year - 110, :end_year => Time.now.year %> and <%= f.date_select :date_of_birth, :default => Time.local(2010,'Jan',1), :start_year => Time.now.year - 110, :end_year => Time.now.year %> None of this changes the behaviour of the first example. Does the default option actually work as described? It seems that this should be a fairly straightforward thing to do. Ta.

• What Happens to Commit Logs on a Branch After Merging?

  - by Levi Hackwith

  Scenario: Programmer creates a branch for project 'foo' called 'my_foo' at revision 5 Programmer makes multiple changes to multiple files as he works on the 'my_foo' feature. At the end of each major step, say adding several new functions to class, the programmer does an svn commit on the appropriate files therefore committing them to the branch After several weeks and many commits later (each commit having a commit log describing what he did), the programmer merges the branch back into the trunk: #Assume the following is being done from inside a working copy of the trunk: svn merge -r 5:15 file:///path/to/repo/branches/my_foo Hazzah! he's merged all his changes back into trunk! There's much rejoicing and drinking of Mountain Dew. Now let's say another programmer comes along a week later and updates their working copy from revision 5 to revision 15. "Wow", they say. "I wonder what's changed since revision 5". The programmer then does an svn status on their working copy and they get something like this: ------------------------------------------------------------------------ r15 | programmer1 | 2010-03-20 21:27:04 -0400 (Sat, 20 Mar 2010) | 1 line Merging Version 2.0 Changes into trunk ------------------------------------------------------------------------ r5 | programmer2 | 2010-02-15 10:59:55 -0500 (Mon, 15 Feb 2010) | 1 line Added assets/images/tumblr_icon.png to trunk What the heck happened to all the notes that the other programmer put in with all of his commits in his branch? Do those not get pulled over during a merge? Am I crazy or just forgetting something?

• Download file in coldfusion and read its content

  - by Deepak

  cfhttp with a get to download the files. Does anyone have an example of cfhttp working? Are there special settings that need to be set up on the server side to get this tag to work. When I try the following code: <CFHTTP METHOD = "get" URL="http://data.bls.gov/PDQ/servlet/SurveyOutputServlet?series_id=LNU04032231&years_option=specific_years&to_year=2010&from_year=2009&delimiter=comma&output_view&output_format=excelTable" path="/Users/Deepak" file="testfile.xls"> Nothing comes back to my computer? How do you get it to pop up the "where do you want to save the file box" dialogue box? I am submitting a form in coldfusion by hitting this link http://data.bls.gov/PDQ/servlet/SurveyOutputServlet?series_id=LNU04032231&years_option=specific_years&to_year=2010&from_year=2009&delimiter=comma&output_view&output_format=excelTable I am getting a excel file as a result. How can I save this file on my local box. Or, is it possible to directly read the content of file without saving it in my local box through coldfusion using cfftp or cfhttp? cfhttp.mimeType is application/vnd.ms-excel in this case. Thanks!!

• deploy a sinatra app with passenger gives only 404, page not founds. Yet a simple rack app works.

  - by berkes

  I have correctly (or prbably not) installed passenger on apache 2. Rack works, but sinatra keeps giving 404's. Here is what works: config.ru: #app = proc do |env| return [200, { "Content-Type" => "text/html" }, "hello <b>world</b>"] end run app Here is what works too: Running the app.rb (see below) with ruby app.rb and then looking at localhost:4567/about and / restarting the app, gives me a correct hello world. w00t. But then there is the sinatra entering the building: config.ru require 'rubygems' require 'sinatra' root_dir = File.dirname(__FILE__) set :environment, ENV['RACK_ENV'].to_sym set :root, root_dir set :app_file, File.join(root_dir, 'app.rb') disable :run run Sinatra::Application and an app.rb require 'rubygems' require 'sinatra' get '/' do "Hallo wereld!" end get '/about' do "Hello world, it's #{Time.now} at the server!" end This keeps giving 404s. /var/logs/apache2/error.log lists these correctly as "404" with something that worries me: 83.XXXXXXXXX - - [30/May/2010 16:06:52] "GET /about " 404 18 0.0007 83.XXXXXXXXX - - [30/May/2010 16:06:56] "GET / " 404 18 0.0007 The thing that worried me, is the space after the / and the /about. Would apache or sinatra go looking for /[space], like /%20? If anyone knows what this problem relates to, maybe a known bug (that I could not find) or a known gotcha? Maybe I am just being stupid and getting "it all wrong?" Otherwise any hints on where to get, read or log more developers data on a running rack, sinatra or passenger app would be helpfull too: to see what sinatra is looking for, for example. Some other information: Running ubuntu 9.04, apache2-mm-prefork (deb), mod_php5, ruby 1.8.7, passenger 2.2.11, sinatra 1.0

• Capturing exit status from STDIN in Perl

  - by zigdon

  I have a perl script that is run with a command like this: /path/to/binary/executable | /path/to/perl/script.pl The script does useful things to the output for the binary file, then exits once STDIN runs out (< returns undef). This is all well and good, except if the binary exits with a non-zero code. From the script's POV, it thinks the script just ended cleanly, and so it cleans up, and exits, with a code of 0. Is there a way for the perl script to see what the exit code was? Ideally, I'd want something like this to work: # close STDIN, and if there was an error, exit with that same error. unless (close STDIN) { print "error closing STDIN: $! ($?)\n"; exit $?; } But unfortunately, this doesn't seem to work: $ (date; sleep 3; date; exit 1) | /path/to/perl/script.pl /tmp/test.out Mon Jun 7 14:43:49 PDT 2010 Mon Jun 7 14:43:52 PDT 2010 $ echo $? 0 Is there a way to have it Do What I Mean?

• Comparing two date ranges within the same table

  - by Danny Herran

  I have a table with sales per store as follows: SQL> select * from sales; ID ID_STORE DATE TOTAL ---------- -------- ---------- -------------------------------------------------- 1 1 2010-01-01 500.00 2 1 2010-01-02 185.00 3 1 2010-01-03 135.00 4 1 2009-01-01 165.00 5 1 2009-01-02 175.00 6 5 2010-01-01 130.00 7 5 2010-01-02 135.00 8 5 2010-01-03 130.00 9 6 2010-01-01 100.00 10 6 2010-01-02 12.00 11 6 2010-01-03 85.00 12 6 2009-01-01 135.00 13 6 2009-01-02 400.00 14 6 2009-01-07 21.00 15 6 2009-01-08 45.00 16 8 2009-01-09 123.00 17 8 2009-01-10 581.00 17 rows selected. What I need to do is to compare two date ranges within that table. Lets say I need to know the differences in sales between 01 Jan 2009 to 10 Jan 2009 AGAINST 01 Jan 2010 to 10 Jan 2010. I'd like to build a query that returns something like this: ID_STORE_A DATE_A TOTAL_A ID_STORE_B DATE_B TOTAL_B ---------- ---------- --------- ---------- ---------- ------------------- 1 2010-01-01 500.00 1 2009-01-01 165.00 1 2010-01-02 185.00 1 2009-01-02 175.00 1 2010-01-03 135.00 1 NULL NULL 5 2010-01-01 130.00 5 NULL NULL 5 2010-01-02 135.00 5 NULL NULL 5 2010-01-03 130.00 5 NULL NULL 6 2010-01-01 100.00 6 2009-01-01 135.00 6 2010-01-02 12.00 6 2009-01-02 400.00 6 2010-01-03 85.00 6 NULL NULL 6 NULL NULL 6 2009-01-07 21.00 6 NULL NULL 6 2009-01-08 45.00 6 NULL NULL 8 2009-01-09 123.00 6 NULL NULL 8 2009-01-10 581.00 So, even if there are no sales in one range or another, it should just fill the empty space with NULL. So far, I've come up with this quick query, but I the "dates" from sales to sales2 sometimes are different in each row: SELECT sales.*, sales2.* FROM sales LEFT JOIN sales AS sales2 ON (sales.id_store=sales2.id_store) WHERE sales.date >= '2010-01-01' AND sales.date <= '2010-01-10' AND sales2.date >= '2009-01-01' AND sales2.date <= '2009-01-10' ORDER BY sales.id_store ASC, sales.date ASC, sales2.date ASC What am I missing?

• HTML Doctype Setting / IE Quirks Mode

  - by Frederico

  I'm working within the parameters of an un-reachable developer, whom has created an html generation system for our products.. Whenever a new page is generated he places: <!-- updated page at 05/MAY/2010 02:58.58 --> <!-- You must use the template manager to modify the formatting of this page. --> resulting in my code looking like: <!-- updated page at 05/MAY/2010 02:55.30 --> <!-- You must use the template manager to modify the formatting of this page. --> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> I don't believe IE read's this doctype at all, as when looking at the developer screen, it renders in Quirks mode... is there any other way to force IE out of this horrible Quirks mode? I've been trying to reach the developer but he has been rather un-available.. Thank you in advance for any help you might have to offer.

• Is using SharePoint as a intranet/extranet portal a good idea?

  - by Rob

  I work for a fortune 500 company in IT and we have developed many systems/applications to do a variety of things. We are in need of some commonality of these applications and a better portal/dashboard/landing page for these applications. So, our customers and employees would log into this portal and see all the "things" that they can do which then link to their own application. This could maybe just iframe in each application inside of this portal to keep brand and navigation consistency. We are trying to decide whether to use SharePoint 2007 or 2010 for this or develop a portal/dashboard of sorts in house. We would like this portal to look and feel very branded to our needs and really not even feel like its using SharePoint (if needed). An example is to provide our own Menu control that drives the navigation if needed. Does anyone have any pros/cons for using SharePoint in such a way? Any advice on implementation (e.g. use 2010, much easier to customize design than 2007, etc)?

• Table valued function only returns CLR error

  - by Anthony

  I have read-only access to a database that was set up for a third-party, closed-source app. Once group of (hopefully) useful table functions only returns the error: Failed to initialize the Common Language Runtime (CLR) v2.0.50727 with HRESULT 0x80131522. You need to restart SQL server to use CLR integration features. (severity 16) But in theory, the third-party app should be able to use the function (either directly or indirectly), so I'm convinced I'm not setting things up right. I'm very new to SQL Server, so I could be missing something obvious. Or I could be missing something really slight, I have no idea. Here is an example of a query that returns the above error: SELECT * FROM dbo.UncompressDataDateRange(4,'Apr 24 2010 12:00AM','Apr 30 2010 12:00AM') Where the function takes three parameters: The Data Set (int) -- basically the data has 6 classifications, and the giant table this should be pulling from has a column to indicate which is which. startDate (smalldatetime) endDate (smalldatetime) There are other, similar functions that expand on the same idea, all returning the same error. Quick Note: I'm not sure if this is relevant, but I was able to connect to the database via SQL Studio (but without the privs to script the functions as code), and a checked the dependency for the above sample function. It turns out that it is a dependent of a view that I have gotten to work, and that view is dependent of the larger, much-hairier data-table. This makes me think I should somehow be pointing the function at the results of the view, but I'm not seeing any documentation that shows how that is done.

• Segmentation fault while feeding in an mpeg file through ffmpeg

  Hi, I've set up FFserver as the streaming server. I'm trying to feed in an mpeg file. But it comes up with a segmentation fault. Does anyone know how to fix this?

• Why does the OnDeserialization not fire for XML Deserialization?

  - by Jonathan

  I have a problem which I have been bashing my head against for the better part of three hours. I am almost certain that I've missed something blindingly obvious... I have a simple XML file: <?xml version="1.0" encoding="utf-8"?> <WeightStore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Records> <Record actual="150" date="2010-05-01T00:00:00" /> <Record actual="155" date="2010-05-02T00:00:00" /> </Records> </WeightStore> I have a simple class structure: [Serializable] public class Record { [XmlAttribute("actual")] public double weight { get; set; } [XmlAttribute("date")] public DateTime date { get; set; } [XmlIgnore] public double trend { get; set; } } [Serializable] [XmlRoot("WeightStore")] public class SimpleWeightStore { [XmlArrayAttribute("Records")] private List<Record> records = new List<Record>(); public List<Record> Records { get { return records; } } [OnDeserialized()] public void OnDeserialized_Method(StreamingContext context) { // This code never gets called Console.WriteLine("OnDeserialized"); } } I am using these in both calling code and in the class files: using System.Xml.Serialization; using System.Runtime.Serialization; I have some calling code: SimpleWeightStore weight_store_reload = new SimpleWeightStore(); TextReader reader = new StringReader(xml); XmlSerializer deserializer = new XmlSerializer(weight_store.GetType()); weight_store_reload = (SimpleWeightStore)deserializer.Deserialize(reader); The problem is that I am expecting OnDeserialized_Method to get called, and it isn't. I suspect it might have something to do with the fact that it's XML deserialization rather than Runtime deserialization, and perhaps I am using the wrong attribute name, but I can't find out what it might be. Any ideas, folks?

• Thinking Sphinx with a date range

  - by Leddo

  Hi, I am implementing a full text search API for my rails apps, and so far have been having great success with Thinking Sphinx. I now want to implement a date range search, and keep getting the "bad value for range" error. Here is a snippet of the controller code, and i'm a bit stuck on what to do next. @search_options = { :page => params[:page], :per_page => params[:per_page]||50 } unless params[:since].blank? # make sure date is in specified format - YYYY-MM-DD d = nil begin d = DateTime.strptime(params[:since], '%Y-%m-%d') rescue raise ArgumentError, "Value for since parameter is not a valid date - please use format YYYY-MM-DD" end @search_options.merge!(:with => {:post_date => d..Time.now.utc}) end logger.info @search_options @posts = Post.search(params[:q], @search_options) When I have a look at the log, I am seeing this bit which seems to imply the date hasn't been converted into the same time format as the Time.now.utc. withpost_date2010-05-25T00:00:00+00:00..Tue Jun 01 17:45:13 UTC 2010 Any ideas? Basically I am trying to have the API request pass in a "since" date to see all posts after a certain date. I am specifying that the date should be in the YYYY-MM-DD format. Thanks for your help. Chris EDIT: I just changed the date parameters merge statement to this @search_options.merge!(:with = {:post_date = d.to_date..DateTime.now}) and now I get this error undefined method `to_i' for Tue, 25 May 2010:Date So obviously there is something still not setup right...

• PHP strtotime() looks like it is expecting a Euro format

  - by Jason Rhodes

  I've been using PHP's strtotime() method to accept a date field on a form. I love how powerful it is, in how it will accept "Tomorrow", "Next Thursday", or (supposedly) any date representation and convert it to the Unix timestamp. It's been working great -- until yesterday. Someone entered "2-4-10" and instead of logging Feb 4th, 2010, it logged April 10, 2002! So it expected Y-M-D instead of M-D-Y. I thought maybe the problem was just using a 2-digit year, so we tried again with "2-4-2010". That logged April 2nd, 2010! At that point I just don't understand what strtotime() is doing. PHP.net says it expects a US English date format. Why then would it assume D-M-Y? Is there a way around this? Or do I have to stop using strtotime()? Note: I just now did a test. When you use slashes instead of hyphen/dashes, it works fine, even with 2/4/10. Why on earth does that matter? And if that's all it is, should I just run str_replace("-", "/", $input) on the form input before passing it to strtotime()?

• Django aggregate query generating SQL error

  - by meepmeep

  I'm using Django 1.1.1 on a SQL Server 2005 db using the latest sqlserver_ado library. models.py includes: class Project(models.Model): name = models.CharField(max_length=50) class Thing(models.Model): project = models.ForeignKey(Project) reference = models.CharField(max_length=50) class ThingMonth(models.Model): thing = models.ForeignKey(Thing) timestamp = models.DateTimeField() ThingMonthValue = models.FloatField() class Meta: db_table = u'ThingMonthSummary' In a view, I have retrieved a queryset called 'things' which contains 25 Things: things = Thing.objects.select_related().filter(project=1).order_by('reference') I then want to do an aggregate query to get the average ThingMonthValue for the first 20 of those Things for a certain period, and the same value for the last 5. For the first 20 I do: averageThingMonthValue = ThingMonth.objects.filter(turbine__in=things[:20],timestamp__range="2009-01-01 00:00","2010-03-00:00")).aggregate(Avg('ThingMonthValue'))['ThingMonthValue__avg'] This works fine, and returns the desired value. For the last 5 I do: averageThingMonthValue = ThingMonth.objects.filter(turbine__in=things[20:],timestamp__range="2009-01-01 00:00","2010-03-00:00")).aggregate(Avg('ThingMonthValue'))['ThingMonthValue__avg'] But for this I get an SQL error: 'Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.' The SQL query being used by django reads: SELECT AVG([ThingMonthSummary].[ThingMonthValue]) AS [ThingMonthValue__avg] FROM [ThingMonthSummary] WHERE ([ThingMonthSummary].[thing_id] IN (SELECT _row_num, [id] FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY [AAAA].[id] ASC) as _row_num, [AAAA].[id] FROM ( SELECT U0.[id] FROM [Thing] U0 WHERE U0.[project_id] = 1 ) AS [AAAA]) as QQQ where 20 < _row_num) AND [ThingMonthSummary].[timestamp] BETWEEN '01/01/09 00:00:00' and '03/01/10 00:00:00') Any idea why it works for one slice of the Things and not the second? I've checked and the two slices do contain the desired Things correctly.

• Establishing a web page bookmarking process - looking for ideas to improve

  - by Matt

  Like many others, I have a process for bookmarking web pages to read later. My requirements for web page bookmarking are: Ability to bookmark pages must be available from all (within reason) platforms - PC/browser, mobile device, etc. Bookmarks must be centrally stored (implicit from #2) so that I can read the bookmarks from anywhere/any device Full text of web pages must be stored Bonus features would be: Bookmarks and page content should be full text searchable Maintain an archive indefinitely Distinguish between what's read vs. unread Bookmarked page content is cleaned up, e.g. ads eliminated, unnecessary html removed, pages better formatted for reading My current process (which addresses most of these requirements) is as follows: I set up a Gmail account with 2 labels, "Bookmarks Unread" and "Bookmarks Read" Gmail filters set up such that depending on the form of the address (using Gmail's '+string' functionality in addresses), the incoming bookmark gets labeled appropriately On each of my browsers/devices, I have an address book entry for [email protected] and [email protected]. If I want to clean up the page content, I use the Readability bookmarklet which does a great job of giving me the essential content only Anywhere I have Firefox, I use the Send Page by Email extension which, with 2 clicks, allows me to send the cleaned-up Readability page URL and content to one of the above email addresses. Where I don't have Firefox (e.g. iPhone or other mobile device) I use the native ability to send the current link via email (most/all apps have them, including the browser, RSS readers, NYTimes, etc.). In most cases (unless it's built into the particular app), this won't include the page body. The process is almost perfect. I've got the central access and ubiquitous access of Gmail as the storage mechanism, full text searchability (due to Gmail, but of course only for the URLs I send from that Firefox extension), a cleaned up page due to Readability, ability to read offline (assuming I use an IMAP client against Gmail) and permanent archiving of content, including what's been read vs. unread. The missing pieces are: The Send Page by Email Firefox extension seems to only send X bytes of a web page. Or some portion. So it limits my full text searchability. Where I don't have Firefox, I can only send the link, so no full text search at all in those cases. Instapaper looks like it meets most of my requirements (and bonus items). The only downside to me (personal preference) is that central storage is based on Instapaper vs. something more broad like Gmail, which as a generalized service and with Google behind it pretty much means it's permanent. I'm not too hung up on this, but I would definitely prefer to keep Gmail if possible. An upside of Instapaper is that it does the page clean-up as well as stores the entire page content, unlike my Firefox extension. Thoughts on addressing the gaps and improving this process further?

• git doesn't show where code was removed.

  - by Andrew Myers

  So I was tasked at replacing some dummy code that our project requires for historical compatibility reasons but has mysteriously dropped out sometime since the last release. Since disappearing code makes me nervous about what else might have gone missing but un-noticed I've been digging through the logs trying to find in what commit this handful of lines was removed. I've tried a number of things including "git log -S'add-visit-resource-pcf'", git blame, and even git bisect with a script that simply checks for the existence of the line but have been unable to pinpoint exactly where these lines were removed. I find this very perplexing, particularly since the last log entry (obtained by the above command) before my re-introduction of this code was someone else adding the code as well. commit 0b0556fa87ff80d0ffcc2b451cca1581289bbc3c Author: Andrew Date: Thu May 13 10:55:32 2010 -0400 Re-introduced add-visit-resource-pcf, see PR-65034. diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index f8e692d..a6f8d38 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -115,6 +115,7 @@ #:add-to-current-resource-pcf #:add-user-package-nickname #:add-value-criteria + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types commit 9fb10e25572c537076284a248be1fbf757c1a6e1 Author: Bob Date: Sun Jan 17 18:35:16 2010 -0500 update-defpackage for Spike 33.1 Delivery diff --git a/spike/hst/scheduler/defpackage.lisp b/spike/hst/scheduler/defpackage.lisp index 983666d..47f1a9a 100644 --- a/spike/hst/scheduler/defpackage.lisp +++ b/spike/hst/scheduler/defpackage.lisp @@ -118,6 +118,7 @@ #:add-user-package-nickname #:add-value-criteria #:add-vars-from-proposal + #:add-visit-resource-pcf #:add-window-to-gs-params #:adjust-derived-resources #:adjust-links-candidate-criteria-types This is for one of our package definition files, but the relevant source file reflects something similar.
