  • 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?

  • Why do my Application Compatibility Toolkit Data Collectors fail to write to my ACT Log Share?

    - by Jay Michaud
    I am trying to get the Microsoft Application Compatibility Toolkit 5.6 (version 5.6.7320.0) to work, but I cannot get the Data Collectors to write to the ACT Log Share. The configuration is as follows. Machine: ACT-Server Domain: mydomain.example.com OS: Windows 7 Enterprise 64-bit Edition Windows Firewall configuration: File and Printer Sharing (SMB-In) is enabled for Public, Domain, and Private networks ACT Log Share: ACT Share permissions*: Group/user names Allow permissions --------------------------------------- Everyone Full Control Administrator Full Control Domain Admins Full Control Administrators Full Control ANONYMOUS LOGON Full Control Folder permissions*: Group/user name Allow permissions Apply to ------------------------------------------------- ANONYMOUS LOGON Read, write & execute This folder, subfolders, and files Domain Admins Full control This folder, subfolders, and files Everyone Read, write & execute This folder, subfolders, and files Administrators Full control This folder, subfolders, and files CREATOR OWNER Full control Subfolders and files SYSTEM Full control This folder, subfolders, and files INTERACTIVE Traverse folder / This folder, subfolders, and files execute file, List folder / read data, Read attributes, Read extended attributes, Create files / write data, Create folders / append data, Write attributes, Write extended attributes, Delete subfolders and files, Delete, Read permissions SERVICE (same as INTERACTIVE) BATCH (same as INTERACTIVE) *I am fully aware that these permissions are excessive, but that is beside the point of this question. Some of the clients running the Data Collector are domain members, but some are not. I am working under the assumption that this is a Windows file sharing permission issue or a network access policy issue, but of course, I could be wrong. It is my understanding that the Data Collector runs in the security context of the SYSTEM account, which for domain members appears on the network as MYDOMAIN\machineaccount. It is also my understanding from reading numerous pieces of documentation that setting the ANONYMOUS LOGON permissions as I have above should allow these computer accounts and non-domain-joined computers to access the share. To test connectivity, I set up the Windows XP Mode virtual machine (VM) on ACT-Server. In the VM, I opened a command prompt running as SYSTEM (using the old "at" command trick). I used this command prompt to run explorer.exe. In this Windows Explorer instance, I typed \ACT-Server\ACT into the address bar, and then I was prompted for logon credentials. The goal, though, was not to be prompted. I also used the "net use /delete" command in the command prompt window to delete connections to the ACT-Server\IPC$ share each time my connection attempt failed. I have made sure that the appropriate exceptions are Since ACT-Server is a domain member, the "Network access: Sharing and security model for local accounts" security policy is set to "Classic - local users authenticate as themselves". In spite of this, I still tried enabling the Guest account and adding permissions for it on the share to no effect. What am I missing here? How do I allow anonymous logons to a shared folder as a step toward getting my ACT Data Collectors to deposit their data correctly? Am I even on the right track, or is the issue elsewhere?

  • How to view pdf files on the Blackberry ?

    - by morpheous
    I recently purchased a blackberry bold - and was rather annoyed to find that I can't read my pdf files on it (unless I purchase something else [can't remember what] from RIM). Are there any free Blackberry apps out there that allow you to read pdf files (without having to connect to the internet)? Failing that, maybe someone can suggest (free) software I can use to change the pdf format to something that my Blackberry can view/read?

  • DVD Share on Vista Home Premium Failing

    - by hpunyon
    UPDATE: - I can't find any Local Policy Editor for Vista Home Premium, as suggested. - I did learn about registry keys: allocatecdroms, allocatefloppies, allocatedasd and tried adding these keys (individually and collectively) and setting them to both 0 or 1. There was no positive affect on read access to the DVD root folder - always Access Denied. ORIGINAL POST: Failing read access to the root folder of a DVD drive in Vista Home Premium laptop using the Guest account - Access Denied. The client is an XP Home PC that can see, but not access, the data in the share. I'm only trying to read the data DVD - not trying to write/burn anything. On the Vista laptop, I have: All Firewalls and Antivirus disabled.UAC disabled. Password checking disabled. "Advanced Shared" the DVD drive, with "Everyone" having full-access permissions to the share. Tried adding Guest and Anonymous users having full-access permissions to the share. RestrictAnonymous=0 set in the registry. Both PC's are in the same workgroup (MSHOME) The XP Home client sees the shared DVD in \Vista_Hostname\ but when I double click the drive icon on the client, I get a popup that access is denied, check with the administrator, etc. I can share other folders on the Vista PC and see and READ these from the XP Home client. If I enable password checking on the Vista side, I get a user/password popup, and I can authenticate (using my known Vista account, that happens to have Admin rights) and then I can get to see and read the DVD data. I need to open this up so that the (default) Guest user can see and access the DVD data files.

  • RAID 1 not performing as expected

    - by Faken
    I recently bought a new 320Gb hard drive for my computer to set up RAID 1 on it for some added security. Installation went as smooth as could possibly be (plug in power, plug in data cable, start up computer, Intel software recognized new drive, right click create RAID 1, done!). However, for some inexplicable reason, I seem to have strange test results when using BENCH32. On my old configuration, a single 7200 rpm drive, I achieved about 60 MB/s write and 70 MB/s read. With a new RAID 1 configuration, I would expect the write to be slightly diminished but read to be significantly improved (though not exactly double speed). However, with the new configuration, I am getting 90 MB/s write and only about 80 MB/s read. I should NOT be getting improved write performance, especially NOT better than read! What's going on? My system setup is: q6600 2.4ghz CPU 4Gb DDR2 667mhz RAM on board Intel ICH9R "RAID chip" 2x Seagate 7200 RPM 320GB drives in RAID 1 Widows 7 home premium 64-bit

  • Reading log files from web application

    - by Egorinsk
    I want to write a small PHP application for monitoring logs on a Debian server, including syslog logs and Apache/PHP messages. The problem here is that Apache user (www-data) has no access to /var/log directory. What would be the best way to grant an access to logs for PHP application? Let's assume that log files can be really large, like hundreds of megabytes. I have some ideas: Write a shell script that would be run via sudo and tail last 512 Kb of log into a separate file that can be read by application - that's ineffective, because of forking a new process and having to read data twice Add www-data to adm group (that can read logs) - that's insecure Start a PHP process via cron every minute to read logs — that's not very good, because it doesn't allow real-time monitoring. Also, this script will be started even when I don't read logs, and consume CPU time (server is in the cloud, and I'll have to pay for it) Create a hardlink for all log files with lowered permissions - I guess, that won't work because logrotate could recreate log files and they'll change inode number. Start a separate nginx/Apache server under privileged user that may read logs. Maybe anyone got a better solution?

  • On Windows Server 2003, permissions are not propagating to a group that is a member of a group

    - by Joshua K
    Windows Server 2003 on i386. FTP server is running as the SYSTEM user/group. Some files we want served (read and write) are owned by the group 'ftp.' ftp has full read/write/whatever permissions on those files and directories. SYSTEM can't read/write those directories. So, I added SYSTEM to the 'ftp' group. Windows happily complied, but even after restarting Filezilla, it still could not read/write those files. Is there any way to do what we want without "re-permissioning" all those files? Running the ftp server as 'ftp' isn't really an option because it also serves files that are owned by SYSTEM (And not ftp). Sigh... :) Any insights?

  • Dual boot: Windows XP and Ubuntu

    - by user19455
    (I know that there are some questions similar to this one, but the ones I have read (and I have read more than one, did not answer my question) I have installed, in two physically different hard drives Windows XP and Ubuntu 9.0. I would like to have a dual boot that, if nothing was pressed, the Windows XP would start automatically. I have read about Grub but got the impression that it wasn't possible to default the operating system to start to something other than Ubuntu. Thanks.

  • Give Access to a Subdirectory Without Giving Access to Parent Directories

    - by allquixotic
    I have a scenario involving a Windows file server where the "owner" wants to dole out permissions to a group of users of the following sort: \\server\dir1\dir2\dir3: Read & Execute and Write \\server\dir1\dir2: No permissions. \\server\dir1: No permissions. \\server: Read & Execute To my understanding, it is not possible to do this because Read & Execute permission must be granted to all the parent directories in a directory chain in order for the operating system to be able to "see" the child directories and get to them. Without this permission, you can't even obtain the security context token when trying to access the nested directory, even if you have full access to the subdirectory. We are looking for ways to get around this, without moving the data from \\server\dir1\dir2\dir3 to \\server\dir4. One workaround I thought of, but which I am not sure if it will work, is creating some sort of link or junction \\server\dir4 which is a reference to \\server\dir1\dir2\dir3. I am not sure which of the available options (if any) would work for this purpose if the user does not have Read & Execute permission on \\server\dir1\dir2 or \\server\dir1, but as far as I know, the options are these: NTFS Symbolic Link, Junction, Hard Link. So the questions: Are any of these methods suitable to accomplish my goal? Are there any other methods of linking or indirectly referencing a directory, which I haven't listed above, which might be suitable? Are there any direct solutions that don't involve granting Read & Execute to \\server\dir1 or \\server\dir2 but still allowing access to \\server\dir1\dir2\dir3?

  • Partition is missing in /dev

    - by haimg
    I'm having a strange problem since I moved from Centos5 to Centos6. I have three disks, first two are used as a RAID1, and third one is a stand-alone backup disk that is not listed in /etc/fstab (it is mounded when needed and then unmounted). My problem: After a boot, /dev/sdc exists but /dev/sdc1 does not. Also, the links in /dev/disks are also absent for the first partition of sdc. Disk itself is fine, and if I hot-remove it and plug it back in, /dev/sdc1 appears ok and everything is working. My question: What subsystem manages auto-discovery of disks, partitions, etc. during the boot process (e.g. what creates /dev/disks/by-label)? How do I configure it to scan /dev/sdc too and create all relevant files and links in /dev ? Edit: Here's the relevant part of dmesg output (the only place sdc appears). It does list sdc1, but it's not in /dev! sd 1:0:0:0: [sdb] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 3:0:0:0: [sdc] 976773168 512-byte logical blocks: (500 GB/465 GiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdc: sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: DMAR:[DMA Read] Request device [00:1e.0] fault addr 361bc000 DMAR:[fault reason 06] PTE Read access is not set sdb1 sdb2 sdb3 sdc1 sda1 sd 1:0:0:0: [sdb] Attached SCSI disk sd 3:0:0:0: [sdc] Attached SCSI disk sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk

  • Extending partition on linux gparted but not more space in the vm

    - by Asken
    I have a vm test installation of a linux running a build server. Unfortunately I just pressed ok when adding the disk and ended up with an 8gb drive to play with. Well into the test the builds are consuming more and more space, of course. The vm drive was resized to 21gb and using gparted I expanded the drive partitions and that all worked fine but when I go back into the console and do df there's still only 8gb available.

    Not a linux geek I am looking for a recommendation which Linux distro to use for a hyper-v based hosting envfironment (so access to the enlightment part easily is important). I Would also love to have something that alloows me to split operating system read only files and user files easily without too much tinkering onto two discs, so that the boot disc can be read only. (reasoning: This would allow me to set up a read only disc that is shared between multiple server instances, with the server disc only containing basically the user files)

    I recently changed permissions on my external usb drive so users by default dont have read permission. Now i realize i cannot search through the drive. after setting 'everyone' permission to read i could again. How do i set it so everyone does not have read permission except for my username (i hate clicking yes to admin prompt everytime i move a file) and allow the system to search the drive when users are allowed to access those files?

  • performance monitoring

    - by Sunny
    I want to monitor CPU usage, disk read/write usage for a particular process, say ./myprocess. To monitor CPU top command seems to be a nice option and for read and write iotop seems to be a handy one. For example to monitor read/write for every second i use the command iotop -tbod1 | grep "myprocess". My difficulty is I just want only three variables to store, namely read/sec, write/sec, cpu usage/sec. Could you help me with a script that combines the outputs the above said three variables from top and iotop to be stored into a log file? Thanks!

  • When using software RAID and LVM on Linux, which IO scheduler and readahead settings are honored?

    - by andrew311
    In the case of multiple layers (physical drives - md - dm - lvm), how do the schedulers, readahead settings, and other disk settings interact? Imagine you have several disks (/dev/sda - /dev/sdd) all part of a software RAID device (/dev/md0) created with mdadm. Each device (including physical disks and /dev/md0) has its own setting for IO scheduler (changed like so) and readahead (changed using blockdev). When you throw in things like dm (crypto) and LVM you add even more layers with their own settings. For example, if the physical device has a read ahead of 128 blocks and the RAID has a readahead of 64 blocks, which is honored when I do a read from /dev/md0? Does the md driver attempt a 64 block read which the physical device driver then translates to a read of 128 blocks? Or does the RAID readahead "pass-through" to the underlying device, resulting in a 64 block read? The same kind of question holds for schedulers? Do I have to worry about multiple layers of IO schedulers and how they interact, or does the /dev/md0 effectively override underlying schedulers? In my attempts to answer this question, I've dug up some interesting data on schedulers and tools which might help figure this out: Linux Disk Scheduler Benchmarking from Google blktrace - generate traces of the i/o traffic on block devices Relevant Linux kernel mailing list thread

  • IIS 7 with PHP in Domain with Windows Authentication

    - by Michal Saiyan Hajdony
    I have Windows Server 2008 R2 x64b installed with IIS 7, PHP 5.5. This server is added to domain exampledomain , so I have win authentication enabled and all others disabled. I left the two default providers NTLM and negotiate, I granted IIS_IUSRS read access to wwwroot. So far it has worked for me only as I am added to the Administrators group which has read/write access to wwwroot folder. Yet, when someone else is trying to connect, he gets a credentials window and when he puts the domain name and password he cannot get access to the page. The issue is solved when I add read permission to "Domain users" - then all works fine. BUT. My issue is that if one opens windows explorer and types \\servername\wwwroot one can see the files and read them. I have never configured IIS before so I know I miss some really important thing. How can I solve the file visibility problem?

  • Break a class in twain, or impose an interface for restricted access?

    - by bedwyr
    What's the best way of partitioning a class when its functionality needs to be externally accessed in different ways by different classes? Hopefully the following example will make the question clear :) I have a Java class which accesses a single location in a directory allowing external classes to perform read/write operations to it. Read operations return usage stats on the directory (e.g. available disk space, number of writes, etc.); write operations, obviously, allow external classes to write data to the disk. These methods always work on the same location, and receive their configuration (e.g. which directory to use, min disk space, etc.) from an external source (passed to the constructor). This class looks something like this: public class DiskHandler { public DiskHandler(String dir, int minSpace) { ... } public void writeToDisk(String contents, String filename) { int space = getAvailableSpace(); ... } public void getAvailableSpace() { ... } } There's quite a bit more going on, but this will do to suffice. This class needs to be accessed differently by two external classes. One class needs access to the read operations; the other needs access to both read and write operations. public class DiskWriter { DiskHandler diskHandler; public DiskWriter() { diskHandler = new DiskHandler(...); } public void doSomething() { diskHandler.writeToDisk(...); } } public class DiskReader { DiskHandler diskHandler; public DiskReader() { diskHandler = new DiskHandler(...); } public void doSomething() { int space = diskHandler.getAvailableSpace(...); } } At this point, both classes share the same class, but the class which should only read has access to the write methods. Solution 1 I could break this class into two. One class would handle read operations, and the other would handle writes: // NEW "UTILITY" CLASSES public class WriterUtil { private ReaderUtil diskReader; public WriterUtil(String dir, int minSpace) { ... diskReader = new ReaderUtil(dir, minSpace); } public void writeToDisk(String contents, String filename) { int = diskReader.getAvailableSpace(); ... } } public class ReaderUtil { public ReaderUtil(String dir, int minSpace) { ... } public void getAvailableSpace() { ... } } // MODIFIED EXTERNALLY-ACCESSING CLASSES public class DiskWriter { WriterUtil diskWriter; public DiskWriter() { diskWriter = new WriterUtil(...); } public void doSomething() { diskWriter.writeToDisk(...); } } public class DiskReader { ReaderUtil diskReader; public DiskReader() { diskReader = new ReaderUtil(...); } public void doSomething() { int space = diskReader.getAvailableSpace(...); } } This solution prevents classes from having access to methods they should not, but it also breaks encapsulation. The original DiskHandler class was completely self-contained and only needed config parameters via a single constructor. By breaking apart the functionality into read/write classes, they both are concerned with the directory and both need to be instantiated with their respective values. In essence, I don't really care to duplicate the concerns. Solution 2 I could implement an interface which only provisions read operations, and use this when a class only needs access to those methods. The interface might look something like this: public interface Readable { int getAvailableSpace(); } The Reader class would instantiate the object like this: Readable diskReader; public DiskReader() { diskReader = new DiskHandler(...); } This solution seems brittle, and prone to confusion in the future. It doesn't guarantee developers will use the correct interface in the future. Any changes to the implementation of the DiskHandler could also need to update the interface as well as the accessing classes. I like it better than the previous solution, but not by much. Frankly, neither of these solutions seems perfect, but I'm not sure if one should be preferred over the other. I really don't want to break the original class up, but I also don't know if the interface buys me much in the long run. Are there other solutions I'm missing?

  • Resumable upload from Java client to Grails web application?

    - by dersteps
    After almost 2 workdays of Googling and trying several different possibilities I found throughout the web, I'm asking this question here, hoping that I might finally get an answer. First of all, here's what I want to do: I'm developing a client and a server application with the purpose of exchanging a lot of large files between multiple clients on a single server. The client is developed in pure Java (JDK 1.6), while the web application is done in Grails (2.0.0). As the purpose of the client is to allow users to exchange a lot of large files (usually about 2GB each), I have to implement it in a way, so that the uploads are resumable, i.e. the users are able to stop and resume uploads at any time. Here's what I did so far: I actually managed to do what I wanted to do and stream large files to the server while still being able to pause and resume uploads using raw sockets. I would send a regular request to the server (using Apache's HttpClient library) to get the server to send me a port that was free for me to use, then open a ServerSocket on the server and connect to that particular socket from the client. Here's the problem with that: Actually, there are at least two problems with that: I open those ports myself, so I have to manage open and used ports myself. This is quite error-prone. I actually circumvent Grails' ability to manage a huge amount of (concurrent) connections. Finally, here's what I'm supposed to do now and the problem: As the problems I mentioned above are unacceptable, I am now supposed to use Java's URLConnection/HttpURLConnection classes, while still sticking to Grails. Connecting to the server and sending simple requests is no problem at all, everything worked fine. The problems started when I tried to use the streams (the connection's OutputStream in the client and the request's InputStream in the server). Opening the client's OutputStream and writing data to it is as easy as it gets. But reading from the request's InputStream seems impossible to me, as that stream is always empty, as it seems. Example Code Here's an example of the server side (Groovy controller): def test() { InputStream inStream = request.inputStream if(inStream != null) { int read = 0; byte[] buffer = new byte[4096]; long total = 0; println "Start reading" while((read = inStream.read(buffer)) != -1) { println "Read " + read + " bytes from input stream buffer" //<-- this is NEVER called } println "Reading finished" println "Read a total of " + total + " bytes" // <-- 'total' will always be 0 (zero) } else { println "Input Stream is null" // <-- This is NEVER called } } This is what I did on the client side (Java class): public void connect() { final URL url = new URL("myserveraddress"); final byte[] message = "someMessage".getBytes(); // Any byte[] - will be a file one day HttpURLConnection connection = url.openConnection(); connection.setRequestMethod("GET"); // other methods - same result // Write message DataOutputStream out = new DataOutputStream(connection.getOutputStream()); out.writeBytes(message); out.flush(); out.close(); // Actually connect connection.connect(); // is this placed correctly? // Get response BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream())); String line = null; while((line = in.readLine()) != null) { System.out.println(line); // Prints the whole server response as expected } in.close(); } As I mentioned, the problem is that request.inputStream always yields an empty InputStream, so I am never able to read anything from it (of course). But as that is exactly what I'm trying to do (so I can stream the file to be uploaded to the server, read from the InputStream and save it to a file), this is rather disappointing. I tried different HTTP methods, different data payloads, and also rearranged the code over and over again, but did not seem to be able to solve the problem. What I hope to find I hope to find a solution to my problem, of course. Anything is highly appreciated: hints, code snippets, library suggestions and so on. Maybe I'm even having it all wrong and need to go in a totally different direction. So, how can I implement resumable file uploads for rather large (binary) files from a Java client to a Grails web application without manually opening ports on the server side?

  • Delphi: EReadError with message ‘Property PageNr does Not Exist’.

    - by lyborko
    Hi, I get SOMETIMES error message: EReadError with message 'Property PageNr does Not exist', when I try to run my own project. I am really desperate, because I see simply nothing what is the cause. The devilish is that it comes up sometimes but often. It concerns of my own component TPage. Here is declaration TPage = class(TCustomControl) // private FPaperHeight, FPaperWidth:Integer; FPaperBrush:TBrush; FPaperSize:TPaperSize; FPaperOrientation:TPaperOrientation; FPDFDocument: TPDFDocument; FPageNr:integer; procedure PaintBasicLayout; procedure PaintInterior; procedure SetPapersize(Value: TPapersize); procedure SetPaperHeight(Value: Integer); procedure SetPaperWidth(Value: Integer); procedure SetPaperOrientation(value:TPaperOrientation); procedure SetPaperBrush(Value:TBrush); procedure SetPageNr(Value:Integer); protected procedure CreateParams(var Params:TCreateParams); override; procedure AdjustClientRect(var Rect: TRect); override; public constructor Create(AOwner: TComponent);override; destructor Destroy;override; // function GetChildOwner:TComponent; override; procedure DrawControl(X,Y :integer; Dx,Dy:Double; Ctrl:TControl;NewCanvas:TCanvas); // procedure GetChildren(Proc:TGetChildProc; Root:TComponent); override; procedure Loaded; override; procedure MouseDown(Button: TMouseButton; Shift: TShiftState; X, Y: Integer); override; procedure Paint; override; procedure PrintOnCanvas(X,Y:integer; rX,rY:Double; ACanvas:TCanvas); procedure PrintOnPDFCanvas(X,Y:integer); procedure PrintOnPrinterCanvas(X,Y:integer); procedure Resize; override; procedure SetPrintKind(APrintKind:TPrintKind; APrintGroupindex:Integer); published property PageNr:integer read FPageNr write SetPageNr; property PaperBrush: TBrush read FPaperBrush write SetPaperBrush; property PaperHeight: integer read FPaperHeight write SetPaperHeight; property PaperWidth: integer read FPaperWidth write SetPaperWidth; property PaperSize: TPaperSize read FPaperSize write SetPaperSize; property PaperOrientation:TPaperOrientation read FPaperOrientation write SetPaperOrientation; property PDFDocument:TPDFDocument read FPDFDocument write FPDFDocument; property TabOrder; end; I thoroughly read the similar topic depicted here: Delphi: EReadError with message 'Property Persistence does Not exist' But here it is my own source code. No third party. Interesting: when I delete PageNr property in my dfm file (unit1.dfm), then pops up : EReadError with message 'Property PaperHeight does Not exist'. when I delete PaperHeight then it will claim PaperWidth and so on... Here is piece of dfm file: object pg1: TPage Left = 128 Top = 144 Width = 798 Height = 1127 PageNr = 0 PaperHeight = 1123 PaperWidth = 794 PaperSize = psA4 PaperOrientation = poPortrait TabOrder = 0 object bscshp4: TBasicShape Left = 112 Top = 64 Width = 105 Height = 105 PrintKind = pkNormal PrintGroupIndex = 0 Zooming = 100 Transparent = False Repeating = False PageRepeatOffset = 1 ShapeStyle = ssVertical LinePosition = 2 end object bscshp5: TBasicShape Left = 288 Top = 24 Width = 105 Height = 105 PrintKind = pkNormal PrintGroupIndex = 0 Zooming = 100 Transparent = False What the hell happens ??????? I have never seen that. I compiled the unit several times... Encoutered no problem. Maybe the cause is beyond this. I feel completely powerless.

  • NTFS and NTFS-3G

    - by MestreLion
    I have a netbook with Ubuntu Netbook 10.04 and a desktop with Mint 10 (~ Ubuntu Desktop 10.10) Both of them have read/write NTFS partitions mounted via /etc/fstab. And it works fine. Ive read on net, google, forums, and several posts here, that NTFS-3G is the driver that allows you to have full access to an NTFS partition, that it is new, great, powerful, yada-yada. But... my entries use plain ntfs, no mention of -3g, and they still work perfectly as read and write. Am I already using ntfs-3g? Does 10.04 onwards use it "under the hood"? How can i check that in my system? Should my /etc/fstab entries should use "ntfs-3g" as the fs? Why some posts refer to mount ntfs, while others say mount ntfs-3g ? Im really confused about where should I use fs-type names (ntfs) or driver names (ntfs-3g?). Or is it irrelevant now, and ntfs is always an "alias" or something for ntfs-3g nowadays? Ive read some posts her, from Oct-10 and Nov-10 e that "announce" that ntfs-3g "finally arrived"... thats way post-Lucid 10.04. Could someone please undo this mess in my head, and explain the relation between ntfs and ntfs-3g, what is the current status (10.04 and 10.10), where should i use each, etc (regarding mount, fstab, etc)? Sorry for the long, confusing, redudant text... im really getting sleepy

  • API Auth vs User Auth

    - by user1626384
    I have read many posts and articles on this topic but still cant connect the dots. I want to make a Rails app that is strictly a JSON API maybe using Sinatra or the rails-api gem. I also want to make both a web client app and an iPhone app which consumes the API. No plans on letting third party dev's use it. So I could create a separate username/password combination for both the web and mobile client and use HTTP Basic over SSL. Each app would have these values as configs in the source and use it to authenticate to the API so only these can make a call. Anyone else trying would get a 401 error returned. This would be considered handling the API authentication. The web and mobile client apps allow end users to sign up and read/write data to the API. When each user is created, I create and save a token in their profile. If a user successfully signs in, I send back the token. On each future read/write then also send along this token in the header. I get the token and lookup the user in the database and make the read/write. Does this sound like an appropriate way to handle it. For the web client, when I initially send back the token, where do I store it. In a cookie? Do I also drop a cookie to handle session state?
