• Effective and simple matching for 2 unequal small-scale point sets

  - by Pavlo Dyban

  I need to match two sets of 3D points, however the number of points in each set can be different. It seems that most algorithms are designed to align images and trimmed to work with hundreds of thousands of points. My case are 50 to 150 points in each of the two sets. So far I have acquainted myself with Iterative Closest Point and Procrustes Matching algorithms. Implementing Procrustes algorithms seems like a total overkill for this small quantity. ICP has many implementations, but I haven't found any readily implemented version accounting for the so-called "outliers" - points without a matching pair. Besides the implementation expense, algorithms like Fractional and Sparse ICP use some statistics information to cancel points that are considered outliers. For series with 50 to 150 points statistic measures are often biased or statistic significance criteria are not met. I know of Assignment Problem in linear optimization, but it is not suitable for cases with unequal sets of points. Are there other, small-scale algorithms that solve the problem of matching 2 point sets? I am looking for algorithm names, scientific papers or C++ implementations. I need some hints to know where to start my search.

• New Write Flash SSDs and more disk trays

  - by Steve Tunstall

  In case you haven't heard, the Write SSDs the ZFSSA have been updated. Much faster now for the same price. Sweet. The new write-flash SSDs have a new part number of 7105026 , so make sure you order the right ones. It's important to note that you MUST be on code level 2011.1.4.0 or higher to use these. They have increased in IOPS from 6,000 to 11,000, and increased throughput from 200MB/s to 350MB/s.    Also, you can now add six SAS HBAs (up from 4) to the 7420, allowing one to have three SAS channels with 12 disk trays each, for a new total of 36 disk trays. With 3TB drives, that's 2.5 Petabytes. Is that enough for you? Make sure you add new cards to the correct slots. I've talked about this before, but here is the handy-dandy matrix again so you don't have to go find it. Remember the rules: You can have 6 of any one kind of card (like six 10GigE cards), but you only really get 8 slots, since you have two SAS cards no matter what. If you want more than 12 disk trays, you need two more SAS cards, so think about expansion later, too. In fact, if you are going to have two different speeds of drives, in other words you want to mix 15K speed and 7,200 speed drives in the same system, I would highly recommend two different SAS channels. So I would want four SAS cards in that system, no matter how many trays you have.

• How do I copy hyperlink only (and not text) to another cell?

  - by OfficeLackey

  I have a spreadsheet where column A displays names. There are a few hundred names and each has a different hyperlink (which links to that person's web page). I want to transfer those hyperlinks across to a different column which has different text in and no hyperlinks. Not every cell in column A has a hyperlink. There are groups of cells merged together, so A2:A7 has one link, A8:A13 the next, A9:10 the next (i.e. number of cells merged is not uniform). e.g. where A2:A7 reads "Bob" and links to www.bob.com, I want I2:I7, which reads, "Smith," and does not link to anything, to link to www.bob.com. I want to do this repeatedly, copying links from A2:A579 into I2:I579. The information is copied from a table within a web page, and that is where the hyperlinks come from.

• Can you share wisdom on using HISTIGNORE in bash?

  - by sage

  I was reading the manpages for bash on the plane and I stumbled across the HISTIGNORE variable. To test it out, I immediately edited my .profile to define this variable: export HISTIGNORE=ls I tested it out and this is great! It excludes plain 'ls' commands from my history without excluding more interesting commands with lengthy paths, but having recently harvested a great deal of wisdom from SU I am eager to know what other commands superusers might recommend or other lessons learned. What can you share about using the HISTIGNORE variable in bash? (Note: I'm about to board my next flight and I have obligations upon arrival, so I will be absent for a number of hours before I can respond to comments...)

• Windows 8 start screen will only find apps matching full words

  - by Ian Oakes

  Since doing a fresh install of Windows 8 x64 RTM I'm having trouble starting apps from the start screen. In previous version I could just start typing the apps name and I would be presented with a list of matches that decreased in number as I continued typing. In the RTM version I have to type complete words to find a match. i.e. if I want to run powershell I have to type in powershell before I get any hits. Like wise if I want to start Visual Studio I have to type visual before I get a match. If I continue and start typing Studio the match goes away and doesn't return until I finish typing studio. This problem does not affect Setting or Files which show all possible matches. Any ideas what is wrong?

• Merge Publication Data Partition Snapshot generation

  - by David Osborn

  I have a merge publication in SQL 2008 R2 with data partitions and I am wondering when I should generate the snapshots for the data partitions. I get an error sometimes when bringing a new subscribe online related to the partition snapshot being out of date and I am wondering if this has to do with the publication snapshot being scheduled at the same time as the partition snapshots. I'm not really sure how the partition snapshot gets generated, but it appears maybe it is getting generated before the publication snapshot. If this is the case how should I be scheduling the partition snapshots to get generated? Should I set them to run x number of minutes after the publication snapshot? this seems kind of poor to do in case the publication snapshot takes awhile or fails. It seems to me the publication snapshot should just run the data partition snapshot agents when it is done if this is the case.

• Copying partial cell to another cell in OpenOffice Calc

  - by Justin

  Cell A1 says 0001 John Smith Cell A2 says 0002 Bill Snyder I want to basically split this, so one column just shows the numbers (0001, 0002, etc.) and then another column just shows the name. The first part is easy. Using the function "=LEFT(A1;4)" I can get 0001. How can I grab the name? Using "RIGHT(A1;99)", for example, will grab the entire string "0001 John Smith". Since each name is different in length, I'm not sure what to do. Can I somehow tell it to grab the whole string EXCEPT the first 4 characters? Or somehow tell it to grab the last 2 WORDS instead of a number of characters like it's asking?

• Are the new Hewlett-Packard "Sandy Bridge"-based notebooks dispatched globally?

  - by leladax

  I'm currently trying to figure out why a European chain retailer is delaying a dv7 [remaining code number is not same with american]; it is listed in their site for several days and while ordered on Monday they still don't have it in their central storage. In an earlier call I was advised that since Intel announces the processor now it may start dispatching from the 6th. Is that true? Is HP obligated not to dispatch it before the 6th? (normally/legally or as a 'deal between gentlemen'). Does anyone know if HP dispatches normally dv7s now? Did they intentionally not dispatch them to retailers before the CES?

• Preventing logrotate's dateext from overwriting files

  - by Thirler

  I'm working with a system where I would like to use the dateext function of logrotate (or some other way) to add the date to a logfile when it is rotated. However in this system it is important that no logging is missing and dateext will overwrite any existing files (which will happen if logrotate is called twice on a day). Is there a reliable way to prevent dateext to overwrite existing files, but instead make another file?. It is acceptable that either no rotate happens or a file is created with a less predictable name (date with an extra number, or the time or something).

• Why can't SVN checkout into a virtualbox shared folder?

  - by Alex Waters

  I am trying to checkout into the virtualbox shared folder with svn 1.7 in ubuntu 12.04 running as a guest on a windows 7 host. I had read that this error was a 1.6 problem, and updated - but am still receiving the error: svn: E000071: Can't move '/mnt/hostShare/code/www/.svn/tmp/svn-hsOG5X' to '/mnt/hostShare/code/www/trunk/statement.aspx?d=201108': Protocol error I found this blog post about the same error in a mac environment, but am finding that changing the folder/file permissions does nothing. vim .svn/entires just has the number 12 - does this need to be changed? Thank you for any assistance! (just another reason for why I prefer git...)

• Storing bundled AMI:s at Amazon EC2

  - by Industrial

  Hi everybody, I am totally new on configuring servers and working with EC2, so please bare with me. I managed after a lot of hair pulling to get a server with Ubuntu up and running with memcached and some other goodies that would make a great package for me. I thought that however, when storing it as an AMI with this tool I would be able to have memcached available next time I launched an instance based upon that image. What can I do to make sure that my configuration is saved properly to an instance? Question number two: - Can I someway make a command that is automatically run on server creation, like initiating memcache with "memcache -d -m 1700 -u root" or even a batch of them?

• Estimate of Hits / Visits / Uniques in order to fall within a given Alexa Tier?

  - by Alex C

  Hi there! I was wondering if anyone could offer up rough estimates that could tell me how many hits a day move you into a given Alexa rank ? Top 5,000 Top 10,000 Top 50,000 Top 100,000 Top 500,000 Top 1,000,000 I know this is incredibly subjective and thus the broad brush strokes with the number ranges... BUT I've got a site currently ranked just over 1.2M worldwide and over 500k in the USA (http://www.alexa.com/siteinfo/fstr.net) Pretty cool for something hand-built on weekends (pat self on back) I was applying to an ad-platform and was told that their program doesn't accept webmasters who have an Alexa rank of greater than 100,000. (Time to take back that pat on the back I guess). I know that my hits in the last 30 days are somewhere on the order of 15,000 uniques and 20,000 pageviews. So I'm wondering how much harder do I have to work to achieve my next "goals"? I'd like to break into the top million, then re-evaluate from there. It'd be nice to know what those targets translate into (very roughly of course). I imagine that alexa ranks and tiers become very much exponential as you move up the ranks, but even hearing annecdotal evidence from other webmasters would be really useful to me. (ie: I have a site that is ranked X and it got Y hits in the last 30 days) Thanks :) - Alex

• Using ConcurrentQueue for thread-safe Performance Bookkeeping.

  - by Strenium

  Just a small tidbit that's sprung up today. I had to book-keep and emit diagnostics for the average thread performance in a highly-threaded code over a period of last X number of calls and no more. Need of the day: a thread-safe, self-managing stats container. Since .NET 4.0 introduced new thread-safe 'Collections.Concurrent' objects and I've been using them frequently - the one in particular seemed like a good fit for storing each threads' performance data - ConcurrentQueue. But I wanted to store only the most recent X# of calls and since the ConcurrentQueue currently does not support size constraint I had to come up with my own generic version which attempts to restrict usage to numeric types only: unfortunately there is no IArithmetic-like interface which constrains to only numeric types – so the constraints here here aren't as elegant as they could be. (Note the use of the Average() method, of course you can use others as well as make your own).   FIFO FixedSizedConcurrentQueue using System;using System.Collections.Concurrent;using System.Linq; namespace xxxxx.Data.Infrastructure{    [Serializable]    public class FixedSizedConcurrentQueue<T> where T : struct, IConvertible, IComparable<T>    {        private FixedSizedConcurrentQueue() { }         public FixedSizedConcurrentQueue(ConcurrentQueue<T> queue)        {            _queue = queue;        }         ConcurrentQueue<T> _queue = new ConcurrentQueue<T>();         public int Size { get { return _queue.Count; } }        public double Average { get { return _queue.Average(arg => Convert.ToInt32(arg)); } }         public int Limit { get; set; }        public void Enqueue(T obj)        {            _queue.Enqueue(obj);            lock (this)            {                T @out;                while (_queue.Count > Limit) _queue.TryDequeue(out @out);            }        }    } }   The usage case is straight-forward, in this case I’m using a FIFO queue of maximum size of 200 to store doubles to which I simply Enqueue() the calculated rates: Usage var RateQueue = new FixedSizedConcurrentQueue<double>(new ConcurrentQueue<double>()) { Limit = 200 }; /* greater size == longer history */   That’s about it. Happy coding!

• How to implement Restricted access to application features

  - by DroidUser

  I'm currently developing a web application, that provides some 'service' to the user. The user will have to select a 'plan' according to which she/he will be allowed to perform application specific actions but up to a limit defined by the plan. A Plan will also limit access to certain features, which will not be available at all for some plans. As an example : say there are 3 plans, 2 actions throughout the application users in plan-1 can perform action-1 3 times, and they can't perform action-2 at all users in plan-2 can perform action-1 10 times, action-2 5 times users in plan-3 can perform action-1 20 times, action-2 10 times So i'm looking for the best way to get this done, and my main concerns besides implementing it, are the following(in no particular order) maintainability/changeability : the number of plans, and type of features/actions will change in the final product industry standard/best practice : for future readiness!! efficiency : ofcourse, i want fast code!! I have never done anything like this before, so i have no clue about how do i go about implementing these functionalities. Any tips/guides/patterns/resources/examples? I did read a little about ACL, RBAC, are they the patterns that i need to follow? Really any sort of feedback will help.

• Outlook Express hangs when selecting multiple emails

  - by Javier Badia

  I'm using Outlook Express (6, I think) on Windows XP. Lately, it has been hanging. Sometimes this happens at startup (right after the main window with all the panes loads) and sometimes when selecting many emails (sometimes as low as three emails at once, sometimes at ten, it's not a fixed number). When this happens, msimn.exe starts to use 98-100% CPU and RAM usage shoots up very quickly, reaching hundreds of megabytes in half a minute. The message pane goes gray instead of showing the message contents. As I said, this sometimes happens right after the main window loads, sometimes when selecting many emails at once. I tried backing up everything, deleting the identities, creating a new one and restoring, but this still happens.

• Windows script to create directories of 3,000 files

  - by uhpl1

  We have some email archiving that is dumping all the emails into a directory. Because of some performance reasons with the server, I want to setup an automated task that will run a script once a day and if there is more than 3,000 (or whatever number) of files in the main directory, create a new directory with the date and move all the main directory files into it. I'm sure someone has already written something similar, so if anyone could point me at it that would be great. Batch file or Powershell would both be fine.

• ifconfig can't see USB wireless

  - by Alex

  I have a wifi USB dongle which I have previously used on a Raspberry Pi (this it is what it is target at). I am trying to get it working on an Nvidia Jetson TK1, however I am having some problems. When I run ifconfig I can't see the wifi, only the ethernet and local loopback. iwconfig reports no wireless extensions on all devices. lsusb does find the device: Bus 002 Device 008: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter So I am not sure why the network tools can't see it. I have tried logging on with a GUI and opening up the network settings through Unity, but cannot see any wireless devices either. Not sure if this is useful, but output of lsmod: Module Size Used by nvhost_vi 2940 0 How can I enable wireless networking on this computer? Command line approach is preferred, but either is fine. UPDATE I don't have the kernel module rt2800usb anywhere on my system. If I do an apt-file search for rt2800usb it lists a number of packages of the pattern: linux-image-3.13.0-*. Perhaps installing one of these will do the trick, but can anyone tell me if its safe to do so?

• Project Jigsaw: On the next train

  - by Mark Reinhold

  I recently proposed to defer Project Jigsaw from Java 8 to Java 9. Feedback on the proposal was about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. The ultimate decision rested, of course, with the Java SE 8 (JSR 337) Expert Group. After due consideration, a strong majority of the EG agreed to my proposal. In light of this decision we can still make progress in Java 8 toward the convergence of the higher-end Java ME Platforms with Java SE. I previously suggested that we consider defining a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. JEP 161 lays out a specific initial proposal for such Profiles. There is also much useful work to be done in Java 8 toward the fully-modular platform in Java 9. Alan Bateman has submitted JEP 162, which proposes some changes in Java 8 to smooth the eventual transition to modules, to provide new tools to help developers prepare for modularity, and to deprecate and then, in Java 9, actually remove certain API elements that are a significant impediment to modularization. Thanks to everyone who responded to the proposal with comments and questions. As I wrote initially, deferring Jigsaw to a Java 9 release in 2015 is by no means a pleasant decision. It does, however, still appear to be the best available option, and it is now the plan of record.

• Randomly and uniquely iterating over a range

  - by Synetech

  Say you have a range of values (or anything else) and you want to iterate over the range and stop at some indeterminate point. Because the stopping value could be anywhere in the range, iterating sequentially is no good because it causes the early values to be accessed more often than later values (which is bad for things that wear out), and also because it reduces performance since it must traverse extra values. Randomly iterating is better because it will (on average) increase the hit-rate so that fewer values have to be accessed before finding the right one, and also distribute the accesses more evenly (again, on average). The problem is that the standard method of randomly jumping around will result in values being accessed multiple times, and has no automatic way of determining when each value has been checked and thus the whole range has been exhausted. One simplified and contrived solution could be to make a list of each value, pick one at random, then remove it. Each time through the loop, you pick one fromt he set of remaining items. Unfortunately this only works for small lists. As a (forced) example, say you are creating a game where the program tries to guess what number you picked and shows how many guess it took. The range is between 0-255 and instead of asking Is it 0? Is it 1? Is it 2?…, you have it guess randomly. You could create a list of 255 numbers, pick randomly and remove it. But what if the range was between 0-232? You can’t really create a 4-billion item list. I’ve seen a couple of implementations RNGs that are supposed to provide a uniform distribution, but none that area also supposed to be unique, i.e., no repeated values. So is there a practical way to randomly, and uniquely iterate over a range?

• Can I prevent Internet Explorer 8 from running scripts until the page is loaded?

  - by Tom W

  When trying to veiw a number of different websites in IE8, I get the following error message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) On investigating the error message, it appears the script is trying to modify parts of the page before it is fully loaded. Is there a setting in IE8 I can change to prevent scripts from running until the page is fully loaded? EDIT: The sites in question used to work just fine, until I had to re-install IE8 for a seperate issue. Then they stopped working.

• The Talent Behind Customer Experience

  - by Christina McKeon

  Earlier, I wrote about Powerful Data Lessons from the Presidential Election. A key component of the Obama team’s data analysis deserves its own discussion—the people. Recruiters are probably scrambling to find out who those Obama data crunchers are and lure them into corporations. For the Obama team, these data scientists became a secret ingredient that the competition didn’t have. This team of analysts knew how to hear the signal and ignore the noise, how to segment and target its base, and how to model scenarios and revise plans based on what the data told them. The talent was the difference. As you work to transform your organization to be more customer-centric, don’t forget that talent is a critical element. Journey mapping is a good start to understanding how your talent impacts your customer experiences. Part of journey mapping includes documenting the “on-stage” and “back-stage” systems and touchpoints. When mapping this part of your customers’ journey, include the roles and talent behind the employee actions—both customer facing and further upstream from that customer touchpoint. Know what each of these roles does, how well you are retaining people in these areas, and your plans to fill these open positions in the future. To use data scientists as an example, this job will be in high demand over the next 10 years. The workforce is shrinking, and higher education institutions may not be able to turn out trained data scientists as fast as you need them. You don’t want to be caught with a skills deficit, so consider how you can best plan for the future talent you will need. Have your existing employees make their career aspirations known to you now. You may find you already have employees willing to take on roles that drive better customer experiences. Then develop customer experience talent from within your organization through targeted learning programs. If you know that you will need to go outside the organization, build those candidate relationships now. Nurture the candidates you want to hire and partner with universities, colleges, and trade associations so you can increase the number of qualified candidates in your talent pool.

• PowerShell script halts execution when Windows XP PC is locked

  - by jshin47

  I have the following script that does a continuous ping and reports failures. It works fine, except the loop apparently "suspends" when the computer is locked. I have confirmed this by starting the script, immediately locking the PC, waiting 10 minutes, and seeing how many pings have occurred. It is nowhere near the expected number. What could be the culprit? Write-Host "Entering monitoring loop..." -Background DarkRed $ping = new-object System.Net.NetworkInformation.Ping $count_up = 0 $count_dn = 0 $count_dd = 0 while ($true) { $result = $ping.send("10.1.1.1") if ($result.Status -eq "Success") { $count_up++ $count_dd = 0 } else { $count_dn++ $count_dd++ $this_date = Get-Date Write-Host "VPN ping failed at time " $this_date -Background Magenta if ($count_dd -gt 3) { Write-Host "***VPN is Down***" `a send_mail_notification("VPN is Down", "") } } if ($Host.UI.RawUI.KeyAvailable -and ("q" -eq $Host.UI.RawUI.ReadKey("IncludeKeyUp,NoEcho").Character)) { Write-Host "Exiting monitoring loop..." -Background DarkRed break; } Start-Sleep -m 250 } $total = $count_up + $count_dn $uptime = 100 * $count_up / $total Write-Host $count_up " out of " $total " pings for a " $uptime "% uptime."

• Is now the right time to move to .NET 4?

  - by bconlon

  The reason I pose this question is that I'm looking at WPF development and so using the latest version seems sensible. However, this means rolling out the .NET 4 runtime to PCs on old versions of the framework. Windows XP is still the number one O/S (estimated 40%+ market share). To run .NET 4 on XP requires Service Pack 3, and although it is good practice to move to the latest service packs, often large companies are slow to keep up due to the extensive testing involved. In fact, .NET 4 is not installed as standard with any Windows O/S as yet - Windows 7 and 2008 Server R2 have 3.5 installed. This is not quite as big an issue as it was for .NET 3.5 as .NET 4 is significantly smaller as it doesn't include the older runtimes - .NET 3.5 SP1 included .NET 3 and .NET 2 and was 250MB, although this was reduced by doing a web install. The size is also reduced a bit if you target the .NET 4 Client Profile, which should be OK for many WPF applications, and I think this may be rolled out as part of Windows service packs soon. But still, if your application is only 4-5 MB and you need 40-50 MB of Framework it is worth consideration before jumping in and using the new shiny features. #

• Can vCenter 4 authenticate and authorize against a virtual directory server??

  - by iforeman

  Hi I am looking into Identity managment in our environment. We currently use Active Directory and Sun's Enterprise Directory server (6.3). I was wondering if I used the Virtual Directory Server of the Enterprise Directory server, would we be able to point the vCenter clients to this Directory service for authentication and authorization rather than at the AD source. The reason for this is that we have more users we want to add to the management role of this server but not all are in AD, a fair number are in the Sun LDAP v3. directory. Thanks in advance Ian

• Suggestions for a Self-serv advertising service

  - by Mystere Man

  I am seeking a self-serv advertising service for my websites, but I have a few restrictions that seem to make what i'm looking for hard to find. Specifically, I want to place "advertise here" links on my pages and allow end-users to purchase advertising on that site, page, and location. These ads will not be part of a national network. Supports multi-tenancy - That is, I have a number of domains using the same "web application" but with customized content per domain. When a customer wants to advertise on a given domain, then the ads will only appear on that domain and on that page of the domain (even though the page name may be the same across multiple domains). Supports fixed ad prices, not just CPC. I need monthly and quarterly pricing regardless of performance. Integrates with OpenX and other ad networks, so that if there is no self-serv on a given zone, it will use national advertising or direct advertising. Shiny Ads has much of this, but i'm looking for alternatives, as their prices are a bit crazy (20%) and can only do PayPal.
