• What is the Best Free Linux Gateway

  - by rockinthesixstring

  I'm looking at moving away from using my DIR-825 as a gateway and moving into a Linux box to do it all for me. I've found IPCop, but I'm looking for something with a little more power. My main goal is basically to be able to point different external domain names to different internal servers. backup.example.com - 192.168.0.5 home.example.com - 192.168.0.1 I host my DNS on my own dedicated server (windows), so I don't know much about doing the gateway thing in my home (my hosting provider does it all for me). Do any of you know of any free Linux Distros that can accomplish what I'm looking for?

• How to deal with "partial" dates (2010-00-00) from MySQL in Django?

  - by Etienne

  In one of my Django projects that use MySQL as the database, I need to have a date fields that accept also "partial" dates like only year (YYYY) and year and month (YYYY-MM) plus normal date (YYYY-MM-DD). The date field in MySQL can deal with that by accepting 00 for the month and the day. So 2010-00-00 is valid in MySQL and it represent 2010. Same thing for 2010-05-00 that represent May 2010. So I started to create a PartialDateField to support this feature. But I hit a wall because, by default, and Django use the default, MySQLdb, the python driver to MySQL, return a datetime.date object for a date field AND datetime.date() support only real date. So it's possible to modify the converter for the date field used by MySQLdb and return only a string in this format 'YYYY-MM-DD'. Unfortunately the converter use by MySQLdb is set at the connection level so it's use for all MySQL date fields. But Django DateField rely on the fact that the database return a datetime.date object, so if I change the converter to return a string, Django is not happy at all. Someone have an idea or advice to solve this problem? How to create a PartialDateField in Django ? EDIT Also I should add that I already thought of 2 solutions, create 3 integer fields for year, month and day (as mention by Alison R.) or use a varchar field to keep date as string in this format YYYY-MM-DD. But in both solutions, if I'm not wrong, I will loose the special properties of a date field like doing query of this kind on them: Get all entries after this date. I can probably re-implement this functionality on the client side but that will not be a valid solution in my case because the database can be query from other systems (mysql client, MS Access, etc.)

• PHP, MySQL: mysql substitute for php in_array function

  - by Devner

  Hi all, Say if I have an array and I want to check if an element is a part of that array, I can go ahead and use in_array( needle, haystack ) to determine the results. I am trying to see the PHP equivalent of this for my purpose. Now you might have an instant answer for me and you might be tempted to say "Use IN". Yes, I can use IN, but that's not fetching the desired results. Let me explain with an example: I have a column called "pets" in DB table. For a record, it has a value: Cat, dog, Camel (Yes, the column data is a comma separated value). Consider that this row has an id of 1. Now I have a form where I can enter the value in the form input and use that value check against the value in the DB. So say I enter the following comma separated value in the form input: CAT, camel (yes, CAT is uppercase & intentional as some users tend to enter it that way). Now when I enter the above info in the form input and submit, I can collect the POST'ed info and use the following query: $search = $_POST['pets']; $sql = "SELECT id FROM table WHERE pets IN ('$search') "; The above query is not fetching me the row that already exists in the DB (remember the record which has Cat, dog, Camel as the value for the pets column?). I am trying to get the records to act as a superset and the values from the form input as subsets. So in this case I am expecting the id value to show up as the values exist in the column, but this is not happending. Now say if I enter just CAT as the form input and perform the search, it should show me the ID 1 row. Now say if I enter just camel, cAT as the form input and perform the search, it should show me the ID 1 row. How can I achieve the above? Thank you.

• Free-flow Alternative to Powerpoint?

  - by Nick Klauer

  So I've been digging around the net trying to find a good set of alternatives to Powerpoint. Part of my interest is that I found one, Prezi, that I liked for it's free-form style. Part of the power of it was that I can zoom out and select any part of the presentation to continue from and it feels much like a mind map or association of thoughts. Are there any other tools that offer anything similar in vein to this way of presenting material? I'm looking for something that just pops differently than a death-by-powerpoint-style presentation, so I would be happy to find tools that help present information in more fluid styles. It doesn't have to mirror Prezi, and I wouldn't want that, but after seeing what Prezi does, I have to think there are other ways of presenting information to a group of people than one square slide at a time.

• How do I setup Linq to SQL and WCF

  - by Jisaak

  So I'm venturing out into the world of Linq and WCF web services and I can't seem to make the magic happen. I have a VERY basic WCF web service going and I can get my old SqlConnection calls to work and return a DataSet. But I can't/don't know how to get the Linq to SQL queries to work. I'm guessing it might be a permissions problem since I need to connect to the SQL Database with a specific set of credentials but I don't know how I can test if that is the issue. I've tried using both of these connection strings and neither seem to give me a different result. <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;Integrated Security=True" providerName="System.Data.SqlClient" /> <add name="GeoDataConnectionString" connectionString="Data Source=SQLSERVER;Initial Catalog=GeoData;User ID=domain\userName; Password=blahblah; Trusted_Connection=true" providerName="System.Data.SqlClient" /> Here is the function in my service that does the query and I have the interface add the [OperationContract] public string GetCity(int cityId) { GeoDataContext db = new GeoDataContext(); var city = from c in db.Cities where c.CITY_ID == 30429 select c.DESCRIPTION; return city.ToString(); } The GeoData.dbml only has one simple table in it with a list of city id's and city names. I have also changed the "Serialization Mode" on the DataContext to "Unidirectional" which from what I've read needs to be done for WCF. When I run the service I get this as the return: SELECT [t0].[DESCRIPTION] FROM [dbo].[Cities] AS [t0] WHERE [t0].[CITY_ID] = @p0 Dang, so as I'm writing this I realize that maybe my query is all messed up?

• Suggestions for Troubleshooting WIndows 7 lockups

  - by Craig L

  I've got a Dell Latitude E6500 that was working fine under Vista x64. I got one of the new Seagate 500GB Hybrid SSD/HD 2.5 drives and thought.. hmm.. let's try Win 7 x64 on it. Bottom line: It works great for hours and then it will hard lock. I don't mean BSOD (or whatever the Win7 equivalent is). I mean my screen is displaying a static image (if there is a clock displayed, it will be frozen at the time the lockup occurred) and the mouse and keyboard do not work. Control-Alt-Delete will not work. I have to hold down the power button to reboot. The event log records NOTHING at the time the lockup occurs. Obviously something is happening to the system to cause the lockup, but the default Windows 7 x64 doesn't log it. How can I log the things Windows doesn't normally log in Event Viewer ?

• Tracking down random BSOD on windows 7

  - by pehrs

  I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?

• property names are different from original Object in the silverlight

  - by kwon

  Following is part of service layer which is provided by WCF service : [Serializable] public class WaitInfo { private string roomName; private string pName; private string tagNo; public string RoomName { get { return roomName; } set { this.roomName = value; } } public string PName { get { return pName; } set { this.pName = value; } } public string TagNo { get { return tagNo; } set { this.tagNo = value; } } } public class Service1 : IService1 { public List<WaitInfo> GetWaitingList() { MyDBDataContext db = new MyDBDataContext(); var query = from w in db.WAIT_INFOs select new WaitInfo { TagNo = w.PATIENT_INFO.TAG_NO, RoomName= w.ROOM_INFO.ROOM_NAME, PName= w.PATIENT_INFO.P_NAME }; List<WaitInfo> result = query.ToList(); return result; } And following is codebehind part of UI layer which is provided by Silverlight public MainPage() { InitializeComponent(); Service1Client s = new Service1Client(); s.GetWaitingListCompleted += new EventHandler<GetWaitingListByCompletedEventArgs>( s_GetWaitingListCompleted); s.GetWaitingListAsync(); } void s_GetWaitingListCompleted(object sender, RadControlsSilverlightApplication1.ServiceReference2.GetWaitingListByCompletedEventArgs e) { GridDataGrid.ItemsSource = e.Result; } And following is xaml code in Silverlight page <Grid x:Name="LayoutRoot"> <data:DataGrid x:Name="GridDataGrid"></data:DataGrid> </Grid> Is is very simple code, however what I am thinking weird is property name of object at "e.Result" in the code behind page. In the service layer, although properties' names are surely "RoomName, PName, TagNo", in the silverlight properties' names are "roomName, pName, tagNo" which are private variable name of the WaitingList Object. Did I something wrong? Thanks in advance.

• Strange behavior with complex Q object filter queries in Django

  - by HWM-Rocker

  Hi I am trying to write a tagging system for Django, but today I encountered a strange behavior in filter or the Q object (django.db.models.Q). I wrote a function, that converts a search string into a Q object. The next step would be to filter the TaggedObject with these query. But unfortunately I get a strange behavior. when I search (id=20) = Q: (AND: ('tags__tag__id', 20)) and it returns 2 Taged Objects with the ID 1127 and 132 when I search (id=4) = Q: (AND: ('tags__tag__id', 4)) and it returns also 2 Objects, but this time 1180 and 1127 until here is everything fine, but when i make a little bit more complex query like (id=4) or (id=20) = Q: (OR: ('tags__tag__id', 4), ('tags__tag__id', 20)) then it returns 4(!) Objects 1180, 1127, 1127, 132 But the object with the ID 1127 is returned twice, but thats not the behaviour I want. Do I have to live with it, and uniqify that list or can I do something different. The representation of the Q object looks fine for me. But the worst is now, when I search for (id=20) and (id=4) = Q: (AND: ('tags__tag__id', 20), ('tags__tag__id', 4)) then it returns no object at all. But why? The representation should be ok and the object with the id 1127 is tagged by both. What am I missing? Here are also the relevant parts of the classes, that are involved: class TaggedObject(models.Model): """ class that represent a tagged object """ tags = generic.GenericRelation('ObjectTagBridge', blank=True, null=True) class ObjectTagBridge(models.Model): """ Help to connect a generic object to a Tag. """ # pylint: disable-msg=W0232,R0903 content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') tag = models.ForeignKey('Tag') class Tag(models.Model): ...

• SQLAlchemy: select over multiple tables

  - by ahojnnes

  Hi, I wanted to optimize my database query: link_list = select( columns=[link_table.c.rating, link_table.c.url, link_table.c.donations_in], whereclause=and_( not_(link_table.c.id.in_( select( columns=[request_table.c.recipient], whereclause=request_table.c.donator==donator.id ).as_scalar() )), link_table.c.id!=donator.id, ), limit=20, ).execute().fetchall() and tried to merge those two selects in one query: link_list = select( columns=[link_table.c.rating, link_table.c.url, link_table.c.donations_in], whereclause=and_( link_table.c.active==True, link_table.c.id!=donator.id, request_table.c.donator==donator.id, link_table.c.id!=request_table.c.recipient, ), limit=20, order_by=[link_table.c.rating.desc()] ).execute().fetchall() the database-schema looks like: link_table = Table('links', metadata, Column('id', Integer, primary_key=True, autoincrement=True), Column('url', Unicode(250), index=True, unique=True), Column('registration_date', DateTime), Column('donations_in', Integer), Column('active', Boolean), ) request_table = Table('requests', metadata, Column('id', Integer, primary_key=True, autoincrement=True), Column('recipient', Integer, ForeignKey('links.id')), Column('donator', Integer, ForeignKey('links.id')), Column('date', DateTime), ) There are several links (donator) in request_table pointing to one link in the link_table. I want to have links from link_table, which are not yet "requested". But this does not work. Is it actually possible, what I'm trying to do? If so, how would you do that? Thank you very much in advance!

• Why doesn't my Droid phone charge when connected to a powered USB hub that is not connected to my computer?

  - by pkaeding

  I notice that my new Motorola Droid phone charges perfectly fine when I connect it to my computer via the USB cable, or if I connect it to a car cigarette lighter-USB adapter, or a wall power-USB adapter. It also works fine when I connect it to a powered USB hub that is connected to my computer. However, if that same powered USB hub is not connected to my computer when I connect the phone, it does not charge. If I connect the computer to the hub, and then connect the phone to the hub, it will charge. If I then disconnect the computer from the hub, the phone will continue to charge. Does anyone know why this is happening, or what I can do to be able to charge my phone from a powered hub, without my computer being present?

• Best way to store and deliver files on a CMS

  - by Tio

  Hi all.. First of all, this isn't another question about storing images on DB vs file system. I'm already storing the images on the file system. I'm just struggling to find a better way to show them to all my users. I' currently using this system. I generate a random filename using md5(uniqueid()), the problem that I'm facing, is that the image is then presented with a link like this: <img src="/_Media/0027a0af636c57b75472b224d432c09c.jpg" /> As you can see this isn't the prettiest way to show a image ( or a file ), and the name doesn't say anything about the image. I've been working with a CMS system at work, that stores all uploaded files on a single table, to access that image it uses something like this: <img src="../getattachment/94173104-e03c-499b-b41c-b25ae05a8ee1/Menu-1/Escritorios.aspx?width=175&height=175" /> As you can see the path to the image, now has a meaning compared to the other one, the problem is that this put's a big strain in the DB, for example, in the last site I made, I have an area that has around 60 images, to show the 60 images, I would have to do at least 60 individual query's to the database, besides the other query's to retrieve the various content on the page. I think you understand my dilemma, has anyone gone trough this problem, that can give me some pointers on how to solve this? Thanks..

• Laptop VGA Output Stopped Working

  - by Jack7890

  I regularly use an external monitor with my laptop. Today, when I booted up, the external monitor refused to work--it just keeps going into power save mode. I tried a different external monitor and had the same problem, so it must be a problem with the laptop itself. Things I've tried: Going into the Display Settings via the Control Panel (I'm running Vista) and attaching/unattaching/reattaching the external monitor. Turning the computer off, unplugging, plugging it back in, and rebooting Blowing into the VGA out to get rid of any dust Toggling through the Fn+F7 options I'm thinking maybe this is an issue with my video card? If necessary, I'm comfortable opening up my laptop and playing around with things, but I'm not sure what to look for. Does anyone have any suggestions?

• MacBook says to replace battery. Should I?

  - by Palantir

  Hi! My MacBook says that battery is not charging, and the battery is completely empty (in fact, pressing the button on the battery illuminates no LEDs). If I plug the power adapter off the mac shuts off immediately. I tried with a spare adapter, and it won't charge it. System information says it has 380 cycles. The battery is 2.5 years old. System profiler says the battery has 0 mAh of capacity, and that it should be replaced. Should I just buy a new battery, or should I bring it to an apple point, and leave it there? They can take a look at it (it's on AppleCare), they told me that they will repair it is there is anything wrong with the charging circuit, but they won't give me a new battery. They will keep the laptop for 10 working days at least... I hate when this happens :P

• jqGrid : "All in One" approach width jqGridEdit Class > how to set a composite primary key ?

  - by Qualliarys

  Hello, How to set a composite primary key for a "All in One" approach (grid defined in JS file, and data using jqGridEdit Class in php file) ? Please, for me a composite primary key of a table T, is a elementary primary key that is defined with some fields belong to this table T ! Here is my test, but i get no data and cannot use the CRUD operations : In my JS file i have this lines code: ... colModel":[ {"name":"index","index":"index","label":"index"}, // <= THAT'S JUST THE INDEX OF MY TABLE {"name":"user","index":"user","label":"user","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"pwd","index":"pwd","label":"pwd","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY {"name":"state","index":"state","label":"state","key":true}, // <= A PART OF MY COMPOSITE PRIMARY KEY ... <= AND SO ON "url":"mygrid_crud.php", "datatype":"json", "jsonReader":{repeatitems:false}, "editurl": "mygrid_crud.php", "prmNames":{"id":"index"} // <= WHAT I NEED TO WRITE HERE ??? ... In my php file (mygrid_crud.php) : ... $grid = new jqGridEdit($conn); $query = "SELECT * FROM mytable WHERE user='$user' and pwd='$pwd' and state='$state'..."; // <= SELECT * it's ok or i need to specify all fields i need ? $grid->SelectCommand = $query; $grid->dataType = "json"; $grid->table = 'mytable'; $grid->setPrimaryKeyId('index'); // <= WHAT I NEED TO WRITE HERE ??? ... $grid->editGrid(); Please, say me what is wrong, and how to do to set a composite primary key in this approach !? Thank you so much for tour responses.

• How to increase signal/range of your Wi-Fi antenna-less repeater/booster over the network?

  - by kenorb

  I've BT Home Hub in the upper flat (2-3 walls behind) and I'm using WPS Wireless-N Wifi Range Router Repeater Extender in my flat where I'm using my laptop. These are antenna-less devices. Are there any life-hack tricks to increase signal/range of my repeater without buying the new more powerful repeater? I've tried already to move my repeater closer to the ceiling or putting the aluminium foil underneath, but it didn't help. Are there any methods, specific plates or materials which can boost the signal? Specification: Model: WN518W2 Frequency range: 2.4-2.4835GHz Wireless transmit power: 14 ~17 dBm (Typical) Wireless Signal Rates With Automatic Fallback: 11n: Up to 300Mbps(dynamic), 11g: Up to 54Mbps(dynamic), 11b: Up to 11Mbps(dynamic) Modulation Technology: DBPSK, DQPSK, CCK, OFDM, 16-QAM, 64-QAM Receiver Sensitivity: 300M: -68dBm@10% PER / 150M: -68dBm@10% PER / 108M: -68dBm@10% PER / 54M: -68dBm@10% PER / 11M: -85dBm@8% PER / 6M: -88dBm@10% PER / 1M: -90dBm@8% PER Product dimensions: 11 * 6 * 7cm

• How to properly shutdown or reboot a Unix/Linux server

  - by hatorade

  What is the correct way to turn off a Unix/Linux server? From my googling, I have learned (hopefully) the following: shutdown: I should use this, with the parameter -h to halt, or the parameter -r to reboot halt: halts the computer (stops the processor? does this physically turn the power of the computer off?). I think this will call shutdown if not at init0, otherwise just halts. reboot: if not at init6, calls shutdown, otherwise just reboots the computer. if all that is correct, then the only thing I can't figure out is what exactly 'halt' does. Does it just stop the processor but not turn the computer physically off? How do I "poweroff" the computer? Thanks

• How to add admin users in 389 LDAP, fedora directory server

  - by chandank

  I want to create couple of Admin users who have access to create/delete users on a particular group/Organization Unit. For example, User: uid=testadmin, ou=people, dc=my,dc=net Should have access to create new users/delete users under ou=People,dc=my,dc=net I tried with below ACI but did not work (target = "ldap:///ou=People,dc=my,dc=net")(targetattr = "*") (version 3.0;acl "testadmin Permissions";allow (proxy)(userdn = "ldap:///uid=testadmin,ou=people,dc=my,dc=net");) I am able to add administrative users from the Directory Server console, but this user data is not stored in ldif files and only stored in binary database at /var/lib/dirsrv/slap-ldap/db/. Only problem is these users have full power and I am not sure how to restrict their access.

• What's the best way to select max over multiple fields in SQL?

  - by allyourcode

  The I kind of want to do is select max(f1, f2, f3). I know this doesn't work, but I think what I want should be pretty clear (see update 1). I was thinking of doing select max(concat(f1, '--', f2 ...)), but this has various disadvantages. In particular, doing concat will probably slow things down. What's the best way to get what I want? update 1: The answers I've gotten so far aren't what I'm after. max works over a set of records, but it compares them using only one value; I want max to consider several values, just like the way order by can consider several values. update 2: Suppose I have the following table: id class_name order_by1 order_by_2 1 a 0 0 2 a 0 1 3 b 1 0 4 b 0 9 I want a query that will group the records by class_name. Then, within each "class", select the record that would come first if you ordered by order_by1 ascending then order_by2 ascending. The result set would consist of records 2 and 3. In my magical query language, it would look something like this: select max(* order by order_by1 ASC, order_by2 ASC) from table group by class_name

• Regular expression for finding non-breaking string names in code and then breaking them up for SQL q

  - by Rob Segal

  I am trying to devlop a regex for finding camel case strings in several code files I am working with so I can break them up into separate words for use in a SQL query. I have strings of the form... EmailAddress FirstName MyNameIs And I want them like this... Email Address First Name My Name Is An example SQL query which I currently have is... select FirstName, MyNameIs from MyTables I need the queries in the form... select FirstName as 'First Name', MyNameIs as 'My Name Is' from MyTables Any time a new capital letter appears that should be a new grouping which I can pick out of the matched string. I currently have the following regex... ([A-Z][a-z]+)+ Which does match the cases I have shown above but when I want to perform a replace I need to define groups. Currently I have tried... (([A-Z])([a-z]+))+ Which sort of works. It will pick out "Address" as the first grouping from "EmailAddress" as opposed to "Email" which is what I was expecting. No doubt there is something I'm misunderstanding here so any help is greatly appreciated.
