  • Derive abstract class from non-abstract class

    - by Jehof
    Is it OK to derive an abstract class from a non-abstract class or is there something wrong with this approach? Here´s a little example: public class Task { // Some Members } public abstract class PeriodicalTask : Task { // Represents a base class for task that has to be done periodicaly. // Some additional Members } public class DailyTask : PeriodicalTask { // Represents a Task that has to be done daily. // Some additional Members } public class WeeklyTask : PeriodicalTask { // Represents a Task that has to be done weekly. // Some additional Members } In the example above i do not want to make the class Task abstract, because i want to instantiate it directly. PeriodicalTask should inherit the functionality from Task and add some additional members but i do not want to instantiate it directly. Only derived class of PeriodicalTask should be instantiated.

  • Why are getters prefixed with the word "get"?

    - by Joey
    Generally speaking, creating a fluid API is something that makes all programmers happy; Both for the creators who write the interface, and the consumers who program against it. Looking beyond conventions, why is it that we prefix all our getters with the word "get". Omitting it usually results in a more fluid, easy to read set of instructions, which ultimately leads to happiness (however small or passive). Consider this very simple example. (pseudo code) Conventional: person = new Person("Joey") person.getName().toLower().print() Alternative: person = new Person("Joey") person.name().toLower().print() Of course this only applies to languages where getters/setters are the norm, but is not directed at any specific language. Were these conventions developed around technical limitations (disambiguation), or simply through the pursuit of a more explicit, intentional feeling type of interface, or perhaps this is just a case of trickle a down norm. What are your thoughts? And how would simple changes to these conventions impact your happiness / daily attitudes towards your craft (however minimal). Thanks.

  • Unix VPS server going down at almost the same time every day

    - by ronnz
    My server load seems to be really spiking and many times the server goes down at the same time each night (Around midnight). I have about 20 cPanel accounts hosted on it and have tried everything I know to try to find what is causing the issue. Some of the things I have tried: Combined all site access logs found in /etc/httpd/domlogs and cannot see anything unusual at the time of server going down. Checked most other logs in the var/log directory and found nothing indicating the issue at the time the server is going down. Checked cron logs and cannot see anything unusual.. See below. Last night CPU spiked to 7.5 at 00:14. What else can I be checking? How can I really monitor to find out the root cause?

  • How can I schedule tasks in a WinForms app?

    - by Greg
    QUESTION: How can I schedule tasks in a WinForms app? That is either (a) what is the best approach / .NET classes/methods to use of (b) if there is an open source component that does this well which one would be recommended. BACKGROUND: Winforms app (.NET v3.5, C#, VS2008) I'm assuming I will run the winforms application always, and just minimise to the system tray when not in use Want a simple approach (didn't want to get into separate service running that UI winforms app talks to etc) Want to be able to let the user select how often to schedule the sync (e.g. hourly, daily - pick time, etc) Ability to at the times when the scheduler fires to run a chunk of code (assume it could be wrapped as a backgroundworker task for example) The application is always running & appears in the system tray

  • Are there tools that would be suitable for maintaining a changelog for a Cabal Haskell package?

    - by Norman Ramsey
    I'm working fast and furiously on a new Haskell package for compiler writers. I'm going through many minor version numbers daily, and the Haskell packaging system, Cabal, doesn't seem to offer any tools for updating version numbers or for maintaining a change log. (Logs are going into git but that's not visible to anyone using the package.) I would kill for something equivalent to Debian's uupdate or dch/debchange tools. Does anyone know of general-purpose tools that could be used to increment version numbers automatically and add an entry to a change log?

  • Extracting and Parsing data with soapUI

    - by James G
    Hi. So I am in need to learn how to use soapUI pretty quick. I'm finding it pretty tedious to start so I was hoping I might be able to get some help here. Here's what I need to do. Lets say we have Company A and Company B which is a subset of Company B. Now Company A offers a webservice accessible by Company B such that Company B can gather daily aggregated data from Company A's database. Now Company B wants to take this data and publish it on their website. What I'd like is a very basic overview of what I need to do to extract and parse the data onto a website. Just the outline of the process so I can get started. What languages should I be using at what stages and what not. Any help would be highly appreciated.

  • SpamAssassin bayesian score discrepancies

    - by CaptSaltyJack
    This makes my brain hurt. For some reason, SpamAssassin is giving high scores to certain emails, but when I test them on the command line, they get a low score. This one particular email has this in the header: X-Spam-Flag: YES X-Spam-Score: 8.521 X-Spam-Level: ******** X-Spam-Status: Yes, score=8.521 tagged_above=-9999 required=5 tests=[BAYES_99=3.5, BAYES_999=0.2, HTML_MESSAGE=0.001, NO_RECEIVED=-0.001, NO_RELAYS=-0.001, RAZOR2_CF_RANGE_51_100=0.5, RAZOR2_CF_RANGE_E8_51_100=1.886, RAZOR2_CHECK=0.922, URIBL_RHS_DOB=1.514] autolearn=no Yet when I dump the raw email into a file msg and run sudo su amavis -c 'spamassassin -t msg', I get this output: Content analysis details: (3.8 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- 1.5 URIBL_RHS_DOB Contains an URI of a new domain (Day Old Bread) [URIs: cliobeads.com] -1.0 ALL_TRUSTED Passed through trusted hosts only via SMTP 0.0 HTML_MESSAGE BODY: HTML included in message -0.0 BAYES_20 BODY: Bayes spam probability is 5 to 20% [score: 0.1855] 1.9 RAZOR2_CF_RANGE_E8_51_100 Razor2 gives engine 8 confidence level above 50% [cf: 100] 0.5 RAZOR2_CF_RANGE_51_100 Razor2 gives confidence level above 50% [cf: 100] 0.9 RAZOR2_CHECK Listed in Razor2 (http://razor.sf.net/) I'm really confused as to why when the email comes in, it gets a completely different score attached to it than when I run spamassassin -t. Is there some other way I should be testing emails? Also, my users have the ability to drag false positives into a folder called "False Positives," and every day a cron job fires off that runs this on every message in every user's folder: sa-learn --dbpath=/var/lib/amavis/.spamassassin --ham /tmp/*-*.eml >/dev/null I ran sudo locate bayes_toks and there's definitely only one bayes DB on the system, in /var/lib/amavis/.spamassassin. I'm clueless, any help would be great and may help restore my sanity!

  • Interviewing - convincing young interviewers that my experience matters [closed]

    - by ritu
    As requested, I split this question from a two part question I asked at http://stackoverflow.com/questions/2482071/modern-web-development-general-question My question is how do i convince the young programmers who interview me that my years of system programming experience, MFC, Win32 programming are still relevant and I should not be automatically rejected because I don't know the differences between Drupal and <pick your technology>. It seems like I can ask a dozen question that these guys won't be able to answer but somehow because I don't know the latest fad counts against me. I do read, but if you don't use what you read in your daily work, you will never have expert knowledge of it. So bottom line: is the only way for me to take a .NET or Java job is for me to start at the bottom all over?

  • Android - making a layout like Entourage/Outlook calendar

    - by teepusink
    Hi, I'm trying to build a layout / view like the Entourage/Outlook calendar view, where when I schedule a time block, a new view will popup overlaying the time block. Something like this one except it's daily and not monthly like in the image http://images.appleinsider.com/office-2008-entourage-10.png What is the best way to implement that? Right now I'm using TableLayout to create the time on the 1st column and supposedly overlay to schedule made on the 2nd column. However, things got very messy especially when the minutes go to 15 minutes and there are overlapping schdule. Wonder if using other layout might work better? Thanks, Tee

  • Web hosting for multiple web sites providing system isolation

    - by Justin
    We have a small number of projects where we expect the client will not be maintaining the installed versions of applications we install to power the site (such as Drupal). Given that an important part of security is keeping things updated, we don't want to host these projects on our Plesk-powered dedicated servers that currently host lots of our other client's websites. Our goal is to find a host where we can deploy isolated instances (be these slices, virtual servers, grid servers, etc) for each individual (or groups of 2-3) web sites as we need them. These instances would be completely separate, so that if one web site were hacked it would not impact any other site. Typical hosting requirements: Linux Apache PHP 5 MySQL Supports Drupal Ability to setup a cron task (but we don't need SSH access) Daily backups Virtualized/cloud hosting (we want to avoid shared) Pricing per site is around $25/month OS is patched automatically Some options we have considered but won't work: MediaTemple: Two major data center-wide security incidents and recent downtime foster doubt about this host's technical ability. Slicehost: This would require us to manage the entire server, which we don't want to do. Rackspace Cloud Sites (formerly Mosso): No backup options. Do you have any recommended hosting options for given these requirements?

  • iCloud + Storage of media in iPhone Documents folder

    - by Michael Morrison
    I, like many developers, got an email from Apple recently that stated we should move our data from the documents directory into another folder to permit more streamlined backup to iCloud. In recent testing it appears that [your app] stores a fair amount of data in its Documents folder. Since iCloud backups are performed daily over Wi-Fi for each user's iOS device, it's important to ensure the best possible user experience by minimizing the amount of data being stored by your app. Marco Arment, of instapaper fame, has a good take on the issue, which is that the recommended location for storing downloadable files is in /Library/Caches. However, the problem is that both /tmp and /Caches can be 'cleaned' anytime the OS decides that the device is running low on storage. If your app is cleaned then the data downloaded by your app and stored by your user is gone. Naturally, the user will blame you and not Apple. What to do?

  • How can I use Perl and RRD to plot ping times?

  • Dedicated server automatic backup solution

    - by Luigi
    I have a dedicated Ubuntu web server in a cloud environment, and I am looking for a nice way to do automated backups. I would like to backup some directories with web apps, and all my MySql databases. As for destination: make snapshots every two hours localy, and every six hours to a remote ftp server. Also delete backup archives older than seven days(localy + ftp), and notify on any problems by email. Now to achieve some of this functionality I use cron + shell script, and http://www.mysqldumper.net/, but really that doesn't answer my needs. Mysqldumper doesn't know automaticly about new databases, and shell script does not notify on problems. It's something I have to check out from time to time, and i don't have trust for. I googled a while, and seems like most people solve this stuff with shell scripts. Is this a method you can trust? Are there any web-gui tools, I'm missing? Maybe there is a smarter startegy for doing this? I'm a little bit confused.

  • Data sync solution?

    - by user321088
    For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

  • Multiple Servers + One MailServer

    - by theomega
    Hy, I got several Linux-Servers (running Debian) where different services run: Database-Servers, Webservers, Applicationsservers, Tools and so on. All Servers are connected to the same internal network. There is also one special Server which is the Mail-Server: All Mailaccounts are stored on this server, it is also the outbound Mailserver for all the other servers. I want all Mails for all servers to get saved on the Mailserver. For example if an cron-job fails on one of the web-servers the mail should not be delivered to the local user but instead to the Mailserver so I get a centralized place for mail storage. How do you set up this scenario? My current setup is: Using postfix as MTA on the Mailserver and using ssmtp on all the other servers. SSMTP is configured to send the mails to the Mailserver. The Mailserver is configured to allow the whole internal network to relay mails using itself. Is this the right way to choose? I also thought about setting up a MTA (postfix) on every server and configure it somehow to forward the mails. What would be the advantage of this solution?

    I do not mean any particular language or methodology. But basics( one have abstracted from ones experience and interaction with smarter people in this field) one should have including concepts, practical issues, tips/techniques/tricks one should be aware of.For example the lessons or ideas may relate to programming,testing,design,project schedules, that are really useful in daily life of software engineer/developer etc ? This may be a good question because it looks not to specific, however experience of many is better than reading from books.I find discussions much helpful than books.Hope every one will have some lessons/ideas to contribute.please substantiate with atleast one example.

  • Sharepoint SSRS: Unexpected Error Encountered

    - by Nicholas
    We are running an intranet website hosted on Sharepoint 2007, serving reports to users via SSRS. Recently, our users are experiencing error when trying to access certain reports with the error message "An unexpected error has occurred". After trying many things, to cut a long story short we manage to temporarily solve the problem by manually running UPDATE STATISTICS on the tables in the database. However, this error will periodically crop up again and again, running UPDATE STATISTICS immediately solved it. I had suggested to run a daily job in the server to auto run UPDATE STATISTICS every few hours or so but was rejected by my team lead. Is there any other workaround for this error? Why does UPDATE STATISTICS solve the problem, I still not very understand?

  • Java HotSpot 1.6 VM, Garbage Collection - Scary PermGen

    - by Gala101
    Hi, My app shows rising 'Old Generation'/'Tenured Generation' size, and when this reaches the max limit for 'Old Gen', then suddenly PermGen size increases. Here are my generation sizings: -Xmx1200m -Xms1200m -Xmn450m -XX:MaxPermSize=600m -XX:+UseParallelGC This is on 32 bit Fedora so can't have a bigger heap than this. The app is not doing any fancy classloading, though it is using Spring IOC and Hibernate, the Spring App-context.xml defines some 1000 Beans. This app starts with 175MB PermGen, which steadily increases to ~250MB in few hrs, stays that way till Tenured Generation reached ~780 MB, then permgen jumps to ~500MB while Old Gen drops to ~500MB. This forces me to restart the App on daily basis, and gives me real scare of looming OutOfMemory Error.. Any insights would be very helpful. Thanks Gala101

  • Openfiler crashing without cause or leaving any log messages

    So my linux machine keeps crashing, without so much as a bye or a leave. I've tried and tried and failed again to work out whats happening. Any help would be much appreciated. Linux chai 2.6.29.6-0.24.smp.gcc3.4.x86_64 #1 SMP Tue Mar 9 05:06:08 GMT 2010 x86_64 x86_64 x86_64 GNU/Linux Openfiler Here is what the /var/log/messages file says at the time of the latest crash. Nothing that unusual - just greg logging in and out via samba. You'll notice there is a cron running for root every minute - ignore this - this isn't the issue either it was some check I've been doing to discover its problem. Jun 2 10:32:01 chai crond(pam_unix)[16529]: session closed for user root Jun 2 10:32:49 chai samba(pam_unix)[15454]: session opened for user greg by (uid=0) Jun 2 10:33:01 chai crond(pam_unix)[16537]: session opened for user root by (uid=0) Jun 2 10:33:04 chai crond(pam_unix)[16537]: session closed for user root Jun 2 10:41:40 chai syslogd 1.4.1: restart.

So basically messages isn't revealing many secrets. dmesg only shows from startup. If there is any output I should paste. Just say when and where and it'll be done. Thanks for your help! Tim

  • How does one make sure or even guarantee server time are sync correctly between dozens of servers across multiple datacenter on different location?

    - by forestclown
    Currently our web applications contain a logic to check if the data sent to the web server is expired or not by comparing the timestamp of the data with the date/time of the server. Everything goes will, until some dude from data center accidentally modify one of the web server date/time and causes some disruptions in our web services. My managers are of course not happy with this, and said we shouldn't use timestamp to check expiry in the first place...anyway.... Network Time Protocol is implemented, because of data centers are spread across different continents so we have one NTP server in each data center. The servers within the data center will have cron jobs to check against the time with their NTP server from the same data center. If time is out of sync it will auto update the server date/time. But then with our managers not happy with it, and think it could still easily causes the same problem. e.g. what if someone accidentally modify the NTP date/time? what if all the NTP servers are out of sync with each other? which NTP servers we can really trust? and blah blah.. So my questions are: What are the current practice to sync date/time between servers across multiple data centers or locations? How does one manages time stamp between web apps? e.g. Server A send data (contain timestamp of Server A) to Server B (compare timestamp between Server B and the timestamp from the data to see if it has expired or not. This is to avoid HTTP replay) Should we really not use timestamp check? Thanks & Best Regards
