• Why might powerpoint not let me adjust the height of a table row?

  - by YGA

  Powerpoint is fighting me every time I try to adjust the height of a table row, and I'm wondering if folks have ideas why that might be the case. See the attached picture; the Argentina row is of height 0.41", while the Nicaragua row is 0.61". Whenever I change to change the Nicaragua row (either by manually moving the row line, or by typing in a new height into the box) powerpoint immediately resets it. The difference? The Argentina row I typed in directly, while the Nicaragua row I pasted in from Excel. Thoughts what might be the difference?

• Resharper Warnings with MVVM

  - by Dan Bryant

  As I implement the MVVM pattern with WPF, I'm finding that Resharper is often warning me that certain properties are never used in my ViewModels. The problem is that they are being used, but only by the data binding system. Has anyone else encountered this annoyance and is there a way to help Resharper realize that these properties are, indeed, being used? I am glad, at least, that VS 2010 properly realizes that [Import] tagged members won't "always be null", but hopefully I can fix this issue as well.

• Deterministic key serialization

  - by Mike Boers

  I'm writing a mapping class which uses SQLite as the storage backend. I am currently allowing only basestring keys but it would be nice if I could use a couple more types hopefully up to anything that is hashable (ie. same requirements as the builtin dict). To that end I would like to derive a deterministic serialization scheme. Ideally, I would like to know if any implementation/protocol combination of pickle is deterministic for hashable objects (e.g. can only use cPickle with protocol 0). I noticed that pickle and cPickle do not match: >>> import pickle >>> import cPickle >>> def dumps(x): ... print repr(pickle.dumps(x)) ... print repr(cPickle.dumps(x)) ... >>> dumps(1) 'I1\n.' 'I1\n.' >>> dumps('hello') "S'hello'\np0\n." "S'hello'\np1\n." >>> dumps((1, 2, 'hello')) "(I1\nI2\nS'hello'\np0\ntp1\n." "(I1\nI2\nS'hello'\np1\ntp2\n." Another option is to use repr to dump and ast.literal_eval to load. This would only be valid for builtin hashable types. I have written a function to determine if a given key would survive this process (it is rather conservative on the types it allows): def is_reprable_key(key): return type(key) in (int, str, unicode) or (type(key) == tuple and all( is_reprable_key(x) for x in key)) The question for this method is if repr itself is deterministic for the types that I have allowed here. I believe this would not survive the 2/3 version barrier due to the change in str/unicode literals. This also would not work for integers where 2**32 - 1 < x < 2**64 jumping between 32 and 64 bit platforms. Are there any other conditions (ie. do strings serialize differently under different conditions)? (If this all fails miserably then I can store the hash of the key along with the pickle of both the key and value, then iterate across rows that have a matching hash looking for one that unpickles to the expected key, but that really does complicate a few other things and I would rather not do it.) Any insights?

• Tools to manage sql 2008 database mirroring?

  - by lemkepf

  We are going to be moving about 20 databases that live on a single instance of sql 2000 to a sql 2008 r2 environment with database mirroring. What I'm looking for is a tool or scripts that will help me manage the conversion and management of those 20db's onto this new mirrored environment easily. There are many steps in setting each DB up and I want to automate as much as possible. Edit: Here are the steps I've been doing manually: Create the same username/passwords from the old sql 2000 server onto new sql 2008 server. Then sync those users/passwords onto the other sql 2008 server with the same SSID's so when we do the db backup and restore they match up. Take a backup of each sql 2000 db's. Copy them to server A. Restore the backup to server A. Backup from server a, copy to server b, restore there. Run the mirror "configure security" wizard. Start mirroring. I've love to be able to script this out or have a tool that does it for me. Thanks! Paul

• Why doesn't Windows 7 allow me to format?

  - by hydroparadise

  Dell support can be fun to deal with right? Ultimately, I have been going back and forth with Dell on an issue and came to reinstalling Windows 7 32-Bit Pro. The problem is that Windows Setup will not let me format. I've read other posts that say Windows 7 must installed on first partition here. But now that confuses me because the computer came shipped with the installation on the third partion as shown in the picture below? Is there a real problem? Or is this a Microsoftism? Should I obliterate the "OEM" partition to make this work? Please note that the format, delete, new, and extend options are grayed out.

• Jython saying "No visible constructors for class"

  - by clutch

  I have a jython servlet as part of a large application running in tomcat5. I tested a few Spring Framework classes and create the objects in the Jython servlet. When I try to create objects of classes in the application I catch an Exception message "No visible constructors for class". These java classes do have a public constructor class, such as: public SchoolImpl() { } I create the object in python: from com.dc.sports.entity import SchoolImpl ... school = SchoolImpl() What am I doing wrong?

• How can I make Windows XP bootable again?

  - by Scott Severance

  Some time ago, I replaced my hard drive. Foolishly, I imaged the individual partitions, not the entire drive. That meant that my system was unbootable. For my primary OS (Linux), that was no problem as I could simply re-run GRUB. However Windows XP remains unbootable. The machine in question is a netbook which doesn't have a CD drive or a restore partition, so I can't boot from a Windows CD and run fixmbr. How can I fix Windows? Here's a picture of what I see when I try to boot Windows from the GRUB menu: I don't actually have an XP CD, since of my two machines, the netbook in question has neither a restore partition nor a CD, and my other XP machine only came with a restore partition. So I'll also need a way to get hold of the necessary files.

• Creating a structure from bytes with ctypes and IronPython

  - by Adal

  I have the following CPython code which I now try to run in IronPython: import ctypes class BarHeader(ctypes.Structure): _fields_ = [ ("id", ctypes.c_char * 4), ("version", ctypes.c_uint32)] bar_file = open("data.bar", "rb") header_raw = bar_file.read(ctypes.sizeof(BarHeader)) header = BarHeader.from_buffer_copy(header_raw) The last line raises this exception: TypeError: expected array, got str I tried BarHeader.from_buffer_copy(bytes(header_raw)) instead of the above, but then the exception message changes to TypeError: expected array, got bytes. Any idea what I'm doing wrong?

• What are these? Are they broken?

  - by Chris Nielsen

  Please excuse the poor image quality: What are the components that I've circled in red? The ones on the left look whole and solid. The ones on the right have cracked tops, and although this picture doesn't show it, there are small brown threads coming out of the top. Are the cracked ones broken, or is that supposed to happen? If they ARE broken, is this something I should worry about? This is a video card, and it appears to be fully functional: I'm using it while writing this post.

• TG2.1: Proper location to store a database session instance?

  - by Lee Olayvar

  I am using a custom database (MongoDB) with TG 2.1 and i am wondering where the proper place to store the PyMongo connection/database instances would be? Eg, at the moment they are getting created inside of my inherited instance of AppConfig. Is there a standard location to store this? Would shoving the variables into the project.model.__init__ be the best location, given that under SQLAlchemy, the database seems to commonly be retrieved via: from project.model import DBSession, metadata Anyway, just curious what the best practice is.

• Windows Server 2008 R2 Virtual Network Setup

  - by jpearl01

  Hi all, Some background: I'm very much new to networking in general, and virtualization in particular. I'm trying to set up a series of VMs as we are transitioning to a thin client setup. I have been supplied a limited number of static ip addresses. The server is located in an offsite building which houses the network we use to connect to the internet, share folders etc. The setup I've been trying to go for is this: The host OS (Windows Server 2008 R2) is bound to one nic using one of the static ips (say, Nic1 and ip 10.255.6.61). I've set up another external virtual network attached to another physical nic , and a virtual private network attached to no nic. There is one VM running the same os (as the host). This VM is connected to both the external virtual network (and uses another static ip say Nic2 and ip 10.255.6.62) and also to the virtual private network (I gave it a static random ip 192.168.88.1 subnet mask 255.255.255.0). This virtual private network is connected to all the other VMs. I'd like to share the internet connection with all the other VMs on the private virtual network, and so I installed the RRAS role on the server connected to Nic2, and selected the option to share the internet over the vpn. I've run through the RRAS wizard a few times, trying different configurations, but none of them seem to be letting the other vms connect to the 'net. The vms seem to connect to the virtual private network fine, they are assigned an ip address and everything, but no internet, and no rest of the network either. The other problem is in general I connect to the vms with RDP. Will that be possible with a setup like this? i.e. will the vms show up as computers on the network? If not, what are my other options? Thanks! ~josh

• Delegating account unlock rights in AD

  - by ewall

  I'm trying to delegate the rights to unlock user accounts in our Active Directory domain. This should be easy, and I've done it before... but every time the user tries to unlock an account (using the LockoutStatus tool), he gets denied with the error "You do not have the necessary permissions to unlock this account." Here's what I've done: I created a domain local group and added the members who should have the rights. This was created over a week ago, so the users have logged out and in again. In ADUC, I've used the Delegate Rights wizard on the OU which contains our user accounts to grant permissions to Read lockoutTime and Writer lockoutTime to the group, per MSKB 279723 I have double-checked the permissions were applied correctly in ADSIEdit. I have forced replication between all domain controllers to ensure the permission changes were copied over. The user testing it has logged out and in again to ensure he has any changes applied to his account. ...That covers all the bases I can think of. Anything else I could be missing?

• Large number of UPDATE queries slowing down page

  - by Bryan Lewis

  I am reading and validating large fixed-width text files (range from 10-50K lines) that are submitted via our ASP.net website (coded in VB.Net). I do an initial scan of the file to check for basic issues (line length, etc). Then I import each row into a MS SQL table. Each DB rows basically consists of a record_ID (Primary, auto-incrementing) and about 50 varchar fields. After the insert is done, I run a validation function on the file that checks each field in each row based on a bunch of criteria (trimmed length, isnumeric, range checks, etc). If it finds an error in any field, it inserts a record into the Errors table, which has an error_ID, the record_ID and an error message. In addition, if the field fails in a particular way, I have to do a "reset" on that field. A reset might consist of blanking the entire field, or simply replacing the value with another value (e.g. replacing the string with a new one that has all illegals chars taken out). I have a 5,000 line test file. The upload, initial check, and import takes about 5-6 seconds. The detailed error check and insert into the Errors table takes about 5-8 seconds (this file has about 1200 errors in it). However, the "resets" part takes about 40-45 seconds for 750 fields that need to be reset. When I comment out the resets function (returning immediately without actually calling the UPDATE stored proc), the process is very fast. With the resets turned on, the pages take 50 seconds to return. My UPDATE stored proc is using some recommended code from http://sommarskog.se/dynamic_sql.html, whereby it uses CASE instead of dynamic SQL: UPDATE dbo.Records SET dbo.Records.file_ID = CASE @field_name WHEN 'file_ID' THEN @field_value ELSE file_ID END, . . (all 50 varchar field CASE statements here) . WHERE dbo.Records.record_ID = @record_ID Is there any way I can help my performance here. Can I somehow group all of these UPDATE calls into a single transaction? Should I be reworking the UPDATE query somehow? Or is it just sheer quantity of 750+ UPDATEs and things are just slow (it's a quad proc server with 8GB ram). Any suggestions appreciated.

• How to design a high-level application protocol for metadata syncing between devices and server?

  - by Jaanus

  I am looking for guidance on how to best think about designing a high-level application protocol to sync metadata between end-user devices and a server. My goal: the user can interact with the application data on any device, or on the web. The purpose of this protocol is to communicate changes made on one endpoint to other endpoints through the server, and ensure all devices maintain a consistent picture of the application data. If user makes changes on one device or on the web, the protocol will push data to the central repository, from where other devices can pull it. Some other design thoughts: I call it "metadata syncing" because the payloads will be quite small, in the form of object IDs and small metadata about those ID-s. When client endpoints retrieve new metadata over this protocol, they will fetch actual object data from an external source based on this metadata. Fetching the "real" object data is out of scope, I'm only talking about metadata syncing here. Using HTTP for transport and JSON for payload container. The question is basically about how to best design the JSON payload schema. I want this to be easy to implement and maintain on the web and across desktop and mobile devices. The best approach feels to be simple timer- or event-based HTTP request/response without any persistent channels. Also, you should not have a PhD to read it, and I want my spec to fit on 2 pages, not 200. Authentication and security are out of scope for this question: assume that the requests are secure and authenticated. The goal is eventual consistency of data on devices, it is not entirely realtime. For example, user can make changes on one device while being offline. When going online again, user would perform "sync" operation to push local changes and retrieve remote changes. Having said that, the protocol should support both of these modes of operation: Starting from scratch on a device, should be able to pull the whole metadata picture "sync as you go". When looking at the data on two devices side by side and making changes, should be easy to push those changes as short individual messages which the other device can receive near-realtime (subject to when it decides to contact server for sync). As a concrete example, you can think of Dropbox (it is not what I'm working on, but it helps to understand the model): on a range of devices, the user can manage a files and folders—move them around, create new ones, remove old ones etc. And in my context the "metadata" would be the file and folder structure, but not the actual file contents. And metadata fields would be something like file/folder name and time of modification (all devices should see the same time of modification). Another example is IMAP. I have not read the protocol, but my goals (minus actual message bodies) are the same. Feels like there are two grand approaches how this is done: transactional messages. Each change in the system is expressed as delta and endpoints communicate with those deltas. Example: DVCS changesets. REST: communicating the object graph as a whole or in part, without worrying so much about the individual atomic changes. What I would like in the answers: Is there anything important I left out above? Constraints, goals? What is some good background reading on this? (I realize this is what many computer science courses talk about at great length and detail... I am hoping to short-circuit it by looking at some crash course or nuggets.) What are some good examples of such protocols that I could model after, or even use out of box? (I mention Dropbox and IMAP above... I should probably read the IMAP RFC.)
