  • Android date/time displaying 0 instead of 12

    - by bEtTy Barnes
    I wonder what's wrong with my code below: // Assign hour set in the picker c.set( Calendar.HOUR, selectedHour ); c.set( Calendar.MINUTE, selectedMinute ); // For alternative times c.add( Calendar.HOUR, SUB_SIX_HOUR ); c.add( Calendar.MINUTE, SUB_FLAT_MINUTE ); hour = c.get( Calendar.HOUR ); minute = c.get( Calendar.MINUTE ); hour = c.get( Calendar.HOUR_OF_DAY ); StringBuilder sb4 = new StringBuilder(); if(hour>=12){ sb4.append(hour-12).append( ":" ).append(minute).append(" PM"); }else if(hour == 0){ sb4.append( "12" ).append( ":" ).append(minute).append( "AM" ); }else{ sb4.append(hour).append( ":" ).append(minute).append(" AM"); } alternative.setText( "Alternative times: " + sb3 + " (9 hours)" + sb4 + " (6 hours)" ); Please help me figure out how to display 12 instead of 0 when the calculated time is 12:00 midnight. Thanks!

  • The woes of (sometimes) storing "date only" in datetimes

    - by Heinzi
    We have two fields from and to (of type datetime), where the user can store the begin time and the end time of a business trip, e.g.: From: 2010-04-14 09:00 To: 2010-04-16 16:30 So, the duration of the trip is 2 days and 7.5 hours. Often, the exact times are not known in advance, so the user enters the dates without a time: From: 2010-04-14 To: 2010-04-16 Internally, this is stored as 2010-04-14 00:00 and 2010-04-16 00:00, since that's what most modern class libraries (e.g. .net) and databases (e.g. SQL Server) do when you store a "date only" in a datetime structure. Usually, this makes perfect sense. However, when entering 2010-04-16 as the to date, the user clearly did not mean 2010-04-16 00:00. Instead, the user meant 2010-04-16 24:00, i.e., calculating the duration of the trip should output 3 days, not 2 days. I can think of a few (more or less ugly) workarounds for this problem (add "23:59" in the UI layer of the to field if the user did not enter a time component; add a special "dates are full days" Boolean field; store "2010-04-17 00:00" in the DB but display "2010-04-16 24:00" to the user if the time component is "00:00"; ...), all having advantages and disadvantages. Since I assume that this is a fairly common problem, I was wondering: Is there a "standard" best-practice way of solving it? If there isn't, have you experienced a similar requirement, how did you solve it and what were the pros/cons of that solution?

    - by dana
    hi there, i'm making a notification system, so that a user in a virtual community to be announced when someone sends him a message, or starts following him (the follow relation is like a friend relation, but it is not necessarily reciprocal) my view function: def notification_view(request, last_checked): u = Relation.objects.filter(date_follow>Notification.objects.get(last_checked=last_checked)) v = Message.objects.filter(date>Notification.objects.get(last_checked=last_checked)) if u: notification_type = follow if notice_settings == receive_notification or notice_settings == only_follow following = u if v: notification_type = message if notice_settings == receive_notification or notice_settings == only_messages message = v return render_to_response('notification/notification.html', { 'following': following, 'message':message, }, context_instance=RequestContext(request)) the models.py: class NoticeType(models.Model): follow = models.ForeignKey(Relations, editable = False) message = models.ForeignKey(Messages) classroom_invitation = models.ForeignKey(Classroom) class Notification(models.Model): receiver = models.ForeignKey(User, editable=False) date = models.DateTimeField(auto_now=True, editable = False) notice_type = models.ForeignKey(NoticeType, editable = False, related_name = "notification_type") sent = models.BooleanField(default = True) last_checked = models.DateTimeField(auto_now=True, editable = False) class NotificationSettings(models.Model): user = models.ForeignKey(User) receive_notifications = models.BooleanField(default = True) only_follow = models.BooleanField(default = False) only_message = models.BooleanField(default = False) only_classroom = models.BooleanField(default = False) #receive_on_email = models.BooleanField(default = False) my problem is: i want last_checked to be the time when someone acceses a link (the notification link). How can i possibily save that time? how can i get it? thanks in avance!

  • linux bash script: set date/time variable to auto-update (for inclusion in file names)

    - by user1859492
    Essentially, I have a standard format for file naming conventions. It breaks down to this: target_dateUTC_timeUTC_tool So, for instance, if I run tcpdump on a target of 'foo', then the file would be foo_dateUTC_timeUTC_tcpdump. Simple enough, but a pain for everyone to constantly (and consistently) enter... so I've tried to create a bash script which sets system variables like so: FILENAME=$TARGET\_$UTCTIME\_$TOOL Then, I can just call the variable at runtime, like so: tcpdump -w $FILENAME.lpc All of this works like a champ. I've got a menu-driven .sh which gives the user the options of viewing the current variables as well as setting them... file generation is a breeze. Unfortunately, by setting the date/time variable, it is locked to the value at the time of creation (naturally). I set the variable like so: UTCTIME=$(/bin/date --utc +"%Y%m%d_%H%M%Z") What I really need is either a way to create a variable which updates at runtime, or (more likely) another way to skin this cat. While scouring for solutions, I came across a similar issues... like this. But, to be honest, I'm stumped on how to marry the two approaches and create a simple, distributable solution. I can post the entire .sh if anyone cares to review (about 120 lines)

  • Does a router have a receiving range?

    - by Aadit M Shah
    So my dad bought a TP-Link router (Model No. TL-WA7510N) which apparently has a transmitting range of 1km; and he believes that it also has a receiving range of 1km. So he's arguing with me that the router (which is a trans-receiver) can communicate with any device in the range of 1km whether or not that device has a transmitting range of 1km. To put it graphically: +----+ 1km +----+ | |------------------------------------------------->| | | TR | | TR | | | <----| | +----+ 100m+----+ So here's the problem: The two devices are 1km apart. The first device has a transmitting range of 1km. The second device only has a transmitting range of 100m. According to my dad the two devices can talk to each other. He says that the first device has a transmitting and a receiving range of 1km which means that it can both send data to devices 1km away and receive data from devices 1km away. To me this makes no sense. If the second device can only send data to devices 100m away then how can the first device catch the transmission? He further argues that for bidirectional communication both the sender and the reciver should have overlapping areas of transmission: According to him if two devices have an overlapping area of transmission then they can communicate. Here neither device has enough transmission power to reach the other. However they have enough receiving power to capture the transmission. Obviously this makes absolutely no sense to me. How can a device sense a transmission which hasn't even reached it yet and go out, capture it and bring it back it. To me a trans-receiver only has a transmission power. It has zero receiving power. Hence for two devices to be able to communicate bidirectionally, the diagram should look like: Hence, from my point of view, both the devices should have a transmission range far enough to reach the other for bidirectional communication to be possible; but no matter how much I try to explain to my dad he adamantly disagrees. So, to put an end to this debate once and for all, who is correct? Is there even such a thing as a receiving range? Can a device fetch a transmission that would otherwise never reach it? I would like a canonical answer on this.

  • Cisco ASA - Unable to create "range" type of network object on 8.2

    - by j2k4j
    I'm wanting to block a range of ip addresses on my Cisco ASA 5520 (8.2) using ASDM 6.4. In the help files/cisco documentation, it says, just create a network object with a "range" type, and use that in a blocking access rule... When I'm accessing the ASA (8.2) with ASDM 6.4, I go to configfirewallobjectnetwork objects & groups, then click "add" to add the IP range as a "network object", I get the following 4 fields to fill out: Name: IP address: Netmask: Description: That's all... In the context-sensitive help files, it says that there should be a Type drop-down to select, with "range" being one of the options, but there is no "Type" drop-down list... If I try to create a "network object group" instead of just "network object", then I get a "Type" drop down list, but it only contains two options: network & host (No "Range" option here either) Can someone help me figure out how to block a range of IP's, using the current 8.2 version on the ASA? Thanks for any pointers or tips!

  • T-SQL select where and group by date

    - by bconlon
    T-SQL has never been my favorite language, but I need to use it on a fairly regular basis and every time I seem to Google the same things. So if I add it here, it might help others with the same issues, but it will also save me time later as I will know where to look for the answers!! 1. How do I SELECT FROM WHERE to filter on a DateTime column? As it happens this is easy but I always forget. You just put the DATE value in single quotes and in standard format: SELECT StartDate FROM Customer WHERE StartDate >= '2011-01-01' ORDER BY StartDate 2. How do I then GROUP BY and get a count by StartDate? Bit trickier, but you can use the built in DATEADD and DATEDIFF to set the TIME part to midnight, allowing the GROUP BY to have a consistent value to work on: SELECT DATEADD (d, DATEDIFF(d, 0, StartDate),0) [Customer Creation Date], COUNT(*) [Number Of New Customers] FROM Customer WHERE StartDate >= '2011-01-01' GROUP BY DATEADD(d, DATEDIFF(d, 0, StartDate),0) ORDER BY [Customer Creation Date] Note: [Customer Creation Date] and [Number Of New Customers] column alias just provide more readable column headers. 3. Finally, how can you format the DATETIME to only show the DATE part (after all the TIME part is now always midnight)? The built in CONVERT function allows you to convert the DATETIME to a CHAR array using a specific format. The format is a bit arbitrary and needs looking up, but 101 is the U.S. standard mm/dd/yyyy, and 103 is the U.K. standard dd/mm/yyyy. SELECT CONVERT(CHAR(10), DATEADD(d, DATEDIFF(d, 0, StartDate),0), 103) [Customer Creation Date], COUNT(*) [Number Of New Customers] FROM Customer WHERE StartDate >= '2011-01-01' GROUP BY DATEADD(d, DATEDIFF(d, 0, StartDate),0) ORDER BY [Customer Creation Date]  #

  • Game: Age of Empires sound good but video "out of range"

    - by Ezekiel
    I'm new to the Ubuntu realm. Currently i'm using Linux Mint 12 with Wine 1.4 and PLAYONLINUX as game loading/playing programs. Video card is MSI GeForce FX5200 (NVIDIA) and is 3d enabled. I can play "Call of Duty 5 demo just fine. My real love is the Age of Empires series games. I loaded the WINE version of AOE 1 demo. No sound and no picture. Black screen with "Out of Range" window in red. I loaded my CD version of AOE 1 through PLAYONLINUX. I get the sound just fine but again the black screen with "Out of Range" window in red. I have used all the monitor settings in both the "settings" and in winecfg. None of the eight monitor options worked in any combination. I have checked all the questions and blogs on this error and tried all I found and no one seems to come up with a real fix. I guess I need to know exactly what the "Out of Range" means. Any help? Anywhere? Thanks
