• Possible to sort via two time stamps and display same row twice.

  - by jamiethompson90

  I'm looking at creating a time table solution. I have a task sheet that looks like Area 1 item 1 startTime endTime Area 1 item1 startTime endTime I wish to create a display where I can view what even is happening next, either endTime or startTime i.e. Newcastle reel 16:45 18:45 Newcastle reel2 17:45 19:45 would output Newcastle reel 16:45 Newcastle reel 17:45 Newcastle reel 18:45 Newcastle reel 19:45 More so, I would like to detect if the time is a startTime or an endTime would I have to enter two rows for each activity (time,area,item, start|end). I can make the interface to the creation of two rows. I just wondered if there was a better solution. Any input is appreciated, Thanks, Jamie

• Setting many key/value pairs

  - by Andrew

  Hi, I'm working on a rake task which imports from a JSON feed into an ActiveRecord called Person. Person has quite a few attributes and rather than write lines of code for setting each attribute I'm trying different methods. The closest I've got is shown below. This works nicely as far as outputing to screen but when I check the values have actually been set on the ActiveRecord itself it's always nil. So it looks like I can't use .to_sym to solve my problem? Any suggestions? I should also mention that I'm just starting out with Ruby, have been doing quite a bit of Objective-c and now need to embrace the Interwebs :) http = Net::HTTP.new(url.host, url.port) http.read_timeout = 30 json = http.get(url.to_s).body parsed = JSON.parse(json) if parsed.has_key? 'code' updatePerson = Person.find_or_initialize_by_code(parsed['code']) puts updatePerson.code parsed.each do |key, value| puts "#{key} is #{value}" symkey = key.to_sym updatePerson[:symkey] = value.to_s updatePerson.save puts "#{key}....." # shows the current key puts updatePerson[:symkey] # shows the correct value puts updatePerson.first_name # a sample key, it's returning nil end

• Where is the Fixedsys font in Vista?

  - by Philipp Lenssen

  I'm trying to locate the font Fixedsys in Windows Vista. I understand it's a hidden system font? My main goal at the end of the day is to get Google Chrome to display Fixedsys (should the CSS file ask for it), and the TrueType replacements I found so far don't look the same... Thanks!

• Reporting. MS Word templates population required

  - by Andrew Florko

  Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

• discrepancy in using AsyncTask, code is executed in weird order

  - by Pentium10

  Hello, In onCreate method I hav the following order of code objItem = new DbClass(this);//the onCreate event creates the database new PrepareAdapter1().execute();//this task uses the tables, but SQLException occures, tables doesn't exists As you see in my short code, I get a new instance of the SQLiteOpenHelper class, which does create the tables in onCreate. And after that I start an AsyncTask instance where I use the created table. But I get SQLiteException as table doesn't not exists. I am using this code in wrong way? I expect the table to be created when I launch the thread.

• Storage drives is causting system crash

  - by Chad

  I'm running Centos 5.4 with 750GB(ntfs) and 2TB drives for storage. Originally I installed the 750, everything seemed fine and then I installed the 2TB drive with NTFS already partitioned. I noticed when I would copy a lot of videos it would crash (no mouse or response from server) about 20min into it. After doing some troubleshooting I noticed the 750 would also crash when doing the same task so I decided that NTFS may be the problem. I unmounted the 2TB drive and tried to partition and format it using ext2 but when using parted it would crash at this point "writing inode tables". Looking at the dmesg logs I believe this is the error "mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining". Any idea as to what could be causing this?

• Activity ignore intent's extra fields

  - by ced

  For example, In an ActivityA there's a button to create an Intent that will start ActivityB in a new task, like this: Intent i = new Intent(this, ActivityB.class); i.setData(Uri.parse("http://www.google.com")); long timestamp = System.currentTimeMillis(); i.putExtra("ts", timestamp); i.addFlag(Intent.FLAG_ACTIVITY_NEW_TASK); Log.d(TAG, "Sending: " + timestamp); startActivity(i); Then in ActivityB's onResume() method, there's this code to check the timestamp: long timestamp = getIntent().getExtras().getLong("ts"); Log.d(TAG, "Receiving: " + timestamp); Now the first time I invoke ActivityB from ActivityA I get the following logs: Sending: 120006000 Receiving: 120006000 Then if I left ActivityB running in the background (by pressing Home button), and start ActivityA then invoke ActivityB again, the following is printed: Sending: 120013000 Receiving: 120006000 It seems although ActivityB is brought to front by the new Intent. The extra field in the intent is being left behind. Is this a bug or an intended behavior?

• MSSQLServer2008\Instance, Why?

  - by Ice

  Hi, im aware of the possibility to create instances but i don't know a real good reason to do it. This way one has per definition at least two sqlserver services running, but what for should this be good? The two instances have to share all the ressouces mainly the RAM. If you have to rename the server you will end up with an access like \NEWSQLServer\OldInstanceName. So what is the case for instances?

• filter log file by defining regexes

  - by fmpdmb

  I have some HUGE log files (50Mb; ~500K lines) I need to start filtering some of the crap out of. The log files are being produced using log4j and have the basic pattern of: [log-level] date-time class etc, etc log-message I'm looking for a way that I can identify a regex start and regex end (or something similar) that will filter out the matching entries from the file so I can more easily wade through these massive files. I'm sure I could write a java program to accomplish this task, but I thought I'd ask the community before going down that path. Thanks in advance.

• How to find the formula of best case and worst case of my algorithm?

  - by rachel7660

  I was given a task. Write an algorithm so that, the input of 2 lists of data, will have at least one in common. So, this is my algorithm: (I write the code in php) $arrayA = array('5', '6', '1', '2', '7'); $arrayB = array('9', '2', '1', '8', '3'); $arrayC = array(); foreach($arrayA as $val){ if(in_array($val, $arrayB)){ array_push($arrayC, $val); } } Thats my own algo, not sure if its a good one. So, based on my algorithm, how to find the formula of best case and worst case (big O)? Note: Please do let me know, if my algorithm is wrong. My goal is " input of 2 lists of data, will have at least one in common."

• Emacs - Disable Some Minibuffer Messages

  - by mellowmaroon

  In Emacs, there are some cases where I would like to prevent messages from appearing in the minibuffer, mainly pertaining to "Beginning/End of buffer" and "Text is read-only". Is there any way I can prevent these messages from appearing in the minibuffer? Also, is there some significant reason I might not want to disable these? At face value, I can just as easily look at the row number and buffer write status on the modeline.

• How to support udev in a kernel module?

  - by Basilevs

  I'm porting a linux kernel module. It used to create a device file for itself (using dirty hacks with syscalls from kernelspace), but now I want to do this in udev. Where can I find documentation on supporting udev in in kernel module? Note that module itself is not a device driver. It serves as a multiplexor for a set of drivers. Therefor default ways of registering devices (i.e. pci ones) are not suitable for my task.

• Where is the chink in Google Chrome's armor?

  - by kudlur

  While browsing with Chrome, I noticed that it responds extremely fast (in comparison with IE and Firefox on my laptop) in terms of rendering pages, including JavaScript heavy sites like gmail. This is what googlebook on Chrome has to say tabs are hosted in process rather than thread. compile javascript using V8 engine as opposed to interpreting. Introduce new virtual machine to support javascript heavy apps introduce "hidden class transitions" and apply dynamic optimization to speed up things. Replace inefficient "Conservative garbage colllection" scheme with more precise garbage collection scheme. Introduce their own task scheduler and memory manager to manage the browser environment. All this sounds so familiar, and Microsoft has been doing such things for long time.. Windows os, C++, C# etc compilers, CLR, and so on. So why isn't Microsoft or any other browser vendor taking Chrome's approach? Is there a flaw in Chrome's approach? If not, is the rest of browser vendor community caught unaware with Google's approach?

• How to setup THIS IPv6 network

  - by Revolter

  I have a network mapped like this : just to experiment IPv6 connectivity, i want to configure my LAN network using IPv6, can some one explain me how to convert the connection between the Desktop and the Laptop to IPv6 without loosing the internet connection ? I don't want to access IPv6 internet, I need to keep my v4. So the end result will be something like an full-IPv6 Laptop accesing IPv4 internet over a some-how-configured Desktop that acting as a NAT.

• Is it possible to run multiple mongod instances on a single set of database files

  - by 9point6

  We have large multi-gigabyte data sets on which we run very complex queries, for example { $or: [ { id: 30000001, ... }, { id: 30000005, ... }, ..., { id: 30001005, ... } ] } It seems that CPU is actually a bottleneck at this point, so I'd be advantageous to be able to run multiple mongod instances on the same set of database files. We've considered using replica sets to this end, but would prefer to not require the extra disk space simply for CPU reasons.

• Having trouble comparing a range of dates entered in a form with records in a mySQL database

  - by Andrew Fox

  I have a table called schedule and a column called Date where the column type is date. In that column I have a range of dates, which is currently from 2012-11-01 to 2012-11-30. I have a small form where the user can enter a range of dates (input names from and to) and I want to be able to compare the range of dates with the dates currently in the database. This is what I have: //////////////////////////////////////////////////////// //////First set the date range that we want to use////// //////////////////////////////////////////////////////// if(isset($_POST['from']) && ($_POST['from'] != NULL)) { $startDate = $_POST['from']; } else { //Default date is Today $startDate = date("Y-m-d"); } if(isset($_POST['to']) && ($_POST['to'] != NULL)) { $endDate = $_POST['to']; } else { //Default day is one month from today $endDate = date("Y-m-d", strtotime("+1 month")); } ////////////////////////////////////////////////////////////////////////////////////// //////Next calculate the total amount of days selected above to use as a limiter////// ////////////////////////////////////////////////////////////////////////////////////// $dayStart = strtotime($startDate); $dayEnd = strtotime($endDate); $total_days = abs($dayEnd - $dayStart) / 86400 +1; echo "Start Date: " . $startDate . "<br>End Date: " . $endDate . "<br>"; echo "Day Start: " . $dayStart . "<br>Day End: " . $dayEnd . "<br>"; echo "Total Days: " . $total_days . "<br>"; //////////////////////////////////////////////////////////////////////////////////// //////Then we're going to see if the dates selected are in the schedule table////// //////////////////////////////////////////////////////////////////////////////////// //Select all of the dates currently in the schedule table between the range selected. $sql = ("SELECT Date FROM schedule WHERE Date BETWEEN '$startDate' AND '$endDate' LIMIT $total_days"); //Run a check on the query to make sure it worked. If it failed then print the error. if(!$result_date_query = $mysqli->query($sql)) { die('There was an error getting the dates from the schedule table [' . $mysqli->error . ']'); } //Set the dates to an array for future use. // $current_dates = $result_date_query->fetch_assoc(); //Loop through the results while a result is being returned. while($row = $result_date_query->fetch_assoc()) { echo "Row: " . $row['Date'] . "<br>"; echo "Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Set this loop to add 1 day to the Start Date until it reaches the End Date for($i = $dayStart; $i <= $dayEnd; $i = strtotime('+1 day', $i)) { $date = date('Y-m-d',$i); echo "Loop Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Run a check to see if any of the dates selected are in the schedule table. if($row['Date'] != $date) { echo "Current Date: " . $row['Date'] . "<br>"; echo "Date: " . $date . "<br>"; echo "It appears as though you've selected some dates that are not in the schedule database.<br>Please correct the issue and try again."; return; } } } //Free the result so something else can use it. $result_date_query->free(); As you can see I've added in some echo statements so I can see what is being produced. From what I can see it looks like my $row['Date'] is not incrementing and staying at the same date. I originally had it set to a variable (currently commented out) but I thought that could be causing problems. I have created the table with dates ranging from 2012-11-01 to 2012-11-15 for testing and entered all of this php code onto phpfiddle.org but I can't get the username provided to connect. Here is the link: PHP Fiddle I'll be reading through the documentation to try and figure out the user connection problem in the meantime, I would really appreciate any direction or advice you can give me.

• Postrouting rule in NAT table

  - by codingfreak

  Hi I have a strange question regarding NAT using iptables. When I do SNAT in a postrouting chain in NAT table at the end of the rule should I give -J ACCEPT? I see counters on the postrouting rule getting incremented but no packet leaving the machine. So does it mean the packet is DROPPED automatically?

• Is it safe to validate a URL with a regexp?

  - by Vilx-

  In my web app I've got a form field where the user can enter an URL. I'm already doing some preliminary client-side validation and I was wondering if I could use a regexp to validate if the entered string is a valid URL. So, two questions: Is it safe to do this with a regexp? A URL is a complex beast, and just like you shouldn't use a regexp for parsing HTML, I'm worried that it might be unsuitable for a URL as well. If it can be done, what would be a good regexp for the task? (I know that Google turns up countless regexps, but I'm worried about their quality). My goal is to prevent a situation where the URL appears in the web page and is unusable by the browser.

• Programmers : Would it help us make better software if we treated our creations as our children?

  - by mcnemesis

  Sometime back, while working on some project, I found a lot of challenges in developing my ideas into a viable and really useful solution. But along the way, I developed more passion for seeing the system work - actually, I wrote in my eDiary "...I want to see this child of mine grow...". The work did mature indeed, and is now a successful system employed in analysis of academic progress in my client's schools. What am really wondering is whether it might help me more (or even other programmers) if this notion of approaching software development as if it were a task of raising one's child could help deliver better software and probably more lovable software :)

• How do I line up subsequent slides with Powerpoint's Motion Paths?

  - by ladenedge

  I'm using Powerpoint's Motion Paths to move images around in my slides. The problem is, on subsequent slides I need the previously-moved images to appear in their Motion Path destinations and I can't seem to get them to line up perfectly. The resulting effect is a smoothly moving image that suddenly "jumps" a few pixels on a slide transition. How can I get images to appear exactly at the end of their Motion Paths in subsequent slides?

• Scheduling jobs from a web environment on Linux

  - by Anders Feder

  Hi. I am developing an application in PHP on Linux/Apache. I want to be able to schedule PHP jobs (scripts) for execution at some specific time in the future from within the application. I know that many people will recommend cron and at, but first of all I don't need recurrence (cron) and secondly and most importantly, I need the solution to be able to scale. At was not designed with race condititions in mind, and if two users try to add a job at the same time one or both may fail. It's also important that jobs are executed at their specified time, and not just 'polled' once per minute or so. Can anyone please suggest solutions for this task? Thank you.
