  • My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

    - by Dominic Bou-Samra
    So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

  • Matching the superclass's constructor's parameter list, is treating a null default value as a non-null value within a constructor a violation of LSP?

    - by Panzercrisis
    I kind of ran into this when messing around with FlashPunk, and I'm going to use it as an example. Essentially the main sprite class is pretty much class Entity. Entity's constructor has four parameters, each with a default value. One of them is graphic, whose default value is null. Entity is designed to be inherited from, with many such subclasses providing their own graphic within their own internal workings. Normally these subclasses would not have graphic in their constructor's parameter lists, but would simply pick something internally and go with it. However I was looking into possibly still adhering to the Liskov Substitution Principal. Which led me to the following example: package com.blank.graphics { import net.flashpunk.*; import net.flashpunk.graphics.Image; public class SpaceGraphic extends Entity { [Embed(source = "../../../../../../assets/spaces/blank.png")] private const BLANK_SPACE:Class; public function SpaceGraphic(x:Number = 0, y:Number = 0, graphic:Graphic = null, mask:Mask = null) { super(x, y, graphic, mask); if (!graphic) { this.graphic = new Image(BLANK_SPACE); } } } } Alright, so now there's a parameter list in the constructor that perfectly matches the one in the super class's constructor. But if the default value for graphic is used, it'll exhibit two different behaviors, depending on whether you're using the subclass or the superclass. In the superclass, there won't be a graphic, but in the subclass, it'll choose the default graphic. Is this a violation of the Liskov Substitution Principal? Does the fact that subclasses are almost intended to use different parameter lists have any bearing on this? Would minimizing the parameter list violate it in a case like this? Thanks.

  • Le e-commerce sécurise-t-il assez ses sites ? Non selon Symantec, pour qui trop de sites malveillants sont des sites "normaux" infectés

    61 % des sites malveillants sont des sites « normaux » infectés D'après Symantec : les entreprises de e-commerce sécurisent-elles assez leurs sites ? D'après Symantec, la contamination via des sites web légitimes est un problème de taille : 61 % des sites malveillants sont en effet des sites « normaux » qui auraient été infectés. « En moyenne, chaque jour, 9 314 sites web malveillants sont identifiés et 1,5 million de personnes sont victimes de cybercriminels, soit 18 personnes par seconde », explique l'éditeur. Ce qui pose la question de savoir comment ces sites sont sécurisés. Notamment pour les plus sensibles (après ceux des Banques) et les plus fréquentés que so...

  • Possible to migrate from non-RAID to RAID 1 and then RAID 5?

    - by stueng
    Using software RAID only Is it possible to start with a 2TB disk full of data and safely add it to a RAID 1 array? Is it then possible to add a third disk and migrate the RAID 1 array into a RAID 5 array? OR Is it possible to start with a 2 disk degraded RAID 5 array and then add the third disk later to create a health RAID 5 array? Backstory: I wish to migrate from a 2 disk NAS (RAID 1) to a 3 disk NAS and only purchase one new disk in doing so

  • Redirecting non existing post to homepage; is that good for SEO?

    - by BlackEagle
    I am checking my website out on Google Webmasters and I am seeing an astonishing 5000 links that could not be found by Google's Crawlers. That's normal, because my website is built in a manner that users can drop their own things, which also lead to 404 pages. Not a problem at all if I can find a workaround of course... So my question is: what if I made a function or a mod rewrite that will check if the link exists (a post for example) and if not, it will redirect it to the home page. Is this good for SEO? Will Google see this as 'link found'? How do I have to look at this problem?

  • Are there non-programming related activities akin to solving programming problems ?

    - by julien
    I'm talking about particular activities, for which you can draw parallels with the specific kind of reasonning needed when solving programming problems. Counter examples are activities that would help in almost any situation, like : take a shower or any other, somewhat passive activities, which are only helpful in triggering this sort of asynchronous problem solving our brain does exercise, because you brain simply works better when you're fit EDIT : It seems this question was quite misunderstood. I wasn't asking about what you can do when stuck on a problem but rather, what kind of activities you have in you spare time that you think help you, more or less directly, solving programing problems.

  • Temporary R+W CIFS share for non-root accounts?

    - by Coder
    I want to set up a cross platform mail client (Thunderbird), and so far I want to use NAS as a profile store. The NAS is CIFS based, and can be mounted on both Windows and Ubuntu. Also the locking works fine for mutex, and setup seems to work as a proof of concept. The problem is the Linux mount. Since I'm using a laptop, I'm not always connected to network, hence, I can't use the /etc/fstab to set up CIFS share with a modified group id. And the share has to be mounted using mount -t cifs ..., which causes it to be owned by root, and owned so badly, that it can't be chowned to the regular user account. This causes read only issues for Thunderbird, which seem to be solved if Thunderbird is launched via sudo. But I would like to avoid that and use a script to mount the share on-demand to a profile location, with profile based privileges and access rights. Is there a way to achieve that?

  • git in non-distributed, independent, lone programming ...best practice(s) ?

    - by explorest
    I am currently studying the git documentation to get a hang of distributed version control workflow and use of git command line. I want to first start using git with small, personal, pet projects so to gain experience before doing it on large scale (i.e., bigger projects, team dev). What areas of the git system should I, as a lone player, devote most of my study time to... what parts should I leave for the larger scale work later on. In other words what features of the git system will fully be grasped in team work only, and therefore should not be too involved with at an individual level?

  • How to prevent Google from indexing non-domain URL of website?

    - by Gavin
    My webhost gives you two URLs for your website: the URL on your shared server, which is something like usr283725992783.webhost.com and your domain URL, which is www.example.com Google is indexing both of these URLs, but obviously I only want www.example.com to be indexed. I can't add "nofollow" tags to usr283725992783.webhost.com because that URL serves the same files as www.example.com. How can I only make Google not follow usr283725992783.webhost.com and keep following www.example.com?

  • How do you track display impressions in Google Analytics on non Google networks?

    - by dee
    Google Analytics has a Multi-Channel funnel analysis feature that we’d like to use to understand assisted conversions and how each channel has impacted on conversion beyond just last interaction attribution. My current understanding is that the impression tracking part of this feature works really well when playing within Google’s search and display networks. Outside of Google’s network I suspect that impression tracking will no longer “just work” and feed back into GA appropriately. What our options are for tracking display impressions on other advertising networks so that we can be attributing value correctly with GA?

  • How to handle this unfortunately non hypothetical situation with end-users?

    - by User Smith
    I work in a medium sized company but with a very small IT force. Last year (2011), I wrote an application that is very popular with a large group of end-users. We hit a deadline at the end of last year and some functionality (I will call funcA from now on) was not added into the application that was wanted at the very end. So, this application has been running in live/production since the end of 2011, I might add without issue. Yesterday, a whole group of end-users started complaining that funcA that was never in the application is no longer working. Our priority at this company is that if an application is broken it must be fixed first prior to prioritized projects. I have compared code and queries and there is no difference since 2011, which is proofA. I then was able to get one of the end-users to admit that it never worked proofB, but since then that end-user has went back and said that it was working previously......I believe the horde of end-users has assimilated her. I have also reviewed my notes for this project which has requirements and daily updates regarding the project which specifically states, "funcA not achieved due to time constraints", proofC. I have spoken with many of them and I can see where they could be confused as they are very far from a programming background, but I also know they are intelligent enough to act in a group in order to bypass project prioritization orders in order to get functionality that they want to make their job easier. The worst part is is that now group think is setting in and my boss and the head of IT is actually starting to believe them, even though there is no code or query changes. As far as reviewing the state of the logic it is very cut and dry to the point of if 1 = 1, funcA will not work. So, this is the end of the description of my scenario, but I am trying not to get severally dinged on my performance metrics due to this which would essentially have me moved to fixing a production problem that doesn't exist that will probably take over 1 month. I am looking for direct answers to this question. This question is not for rants, polling, or discussions as this is not the format for StackExchange. Please don't downvote me too terribly it is pretty common on this specific site of stack, I am looking for honest answers to this situation and I couldn't find a forum more appropriate.

  • The Ubuntu Advantage Service right for my non-profit?

    - by Robert
    My small 5 computer office currently runs on Ubuntu. 2 of the desktops run Windows7 in Sun Virtualbox software, and are used for Quickbooks. I am going off to college, and I am looking for a paid tech support solution to replace my IT position. I have an approx $300/mth budget, and I am wiling to discuss higher rates. Everyone in the office is currently comfortable with regular desktop usage, but I am handling all of the software installation and updates. I was hoping to get a total support package for all of their tech related questions, but I cannot find any services which will support linux. Is the Ubuntu Advantage Service something which can take my place? They would mostly need network help, printer help, and an occasional software compatibly troubleshooting session. If this is not a solution, does anyone know of a tech support forum/hotline which would cover all of this? Thank you for reading.

  • Can other domain registrars view non-public whois information?

    - by user3188544
    If my domains are hosted at a registrar (lets take Gandi, for example) and it has privacy protection on the whois information, can another ICANN-accredited registrar (GoDaddy, for example) still view my actual information that is behind the privacy guard? i.e. I don't have a GoDaddy account. But, since they are ICANN-accredited, could they access the real whois info without the privacy protection?

  • Lubuntu 12.04 is a non-LTS release - does this mean that LXDE isn't, either?

    - by MHC
    Lubuntu 12.04 is not a long-term-support release. That's mostly due to a lack of manpower. But I don't use Lubuntu on my machine, I use LXDE over stock Ubuntu 12.04 LTS. So my question is: In the next five years, will there be security updates and bug fixes for LXDE-packages such as Openbox, PCmanFM and LXsession? Or does the "LTS" in 12.04 LTS only include stock Unity packages? I guess this question is just as relevant for any other DE out there.

  • Best way to slice up a non rectangular image?

    - by Hoff
    I have the image below and need to create a rollover for each "piece" or arrow in the circle. Because the image isn't rectangular, it boggles how me how I'm going to do this without having badly overlapping pieces. As you can see from the image below, the slices will overlap each other (quite a bit), which will not be good for the rollover. Does anybody have any ideas as to how to accomplish this without resorting to Flash or HTML5? The majority of our site's users use dinosaur browsers that don't support HTML5. Here's the link to the image: http://img812.imageshack.us/img812/3166/wheela.png

  • Do objects maintain identity under all non-cloning conditions in PHP?

    - by Buttle Butkus
    PHP 5.5 I'm doing a bunch of passing around of objects with the assumption that they will all maintain their identities - that any changes made to their states from inside other objects' methods will continue to hold true afterwards. Am I assuming correctly? I will give my basic structure here. class builder { protected $foo_ids = array(); // set in construct protected $foo_collection; protected $bar_ids = array(); // set in construct protected $bar_collection; protected function initFoos() { $this->foo_collection = new FooCollection(); foreach($this->food_ids as $id) { $this->foo_collection->addFoo(new foo($id)); } } protected function initBars() { // same idea as initFoos } protected function wireFoosAndBars(fooCollection $foos, barCollection $bars) { // arguments are passed in using $this->foo_collection and $this->bar_collection foreach($foos as $foo_obj) { // (foo_collection implements IteratorAggregate) $bar_ids = $foo_obj->getAssociatedBarIds(); if(!empty($bar_ids) ) { $bar_collection = new barCollection(); // sub-collection to be a component of each foo foreach($bar_ids as $bar_id) { $bar_collection->addBar(new bar($bar_id)); } $foo_obj->addBarCollection($bar_collection); // now each foo_obj has a collection of bar objects, each of which is also in the main collection. Are they the same objects? } } } } What has me worried is that foreach supposedly works on a copy of its arrays. I want all the $foo and $bar objects to maintain their identities no matter which $collection object they become of a part of. Does that make sense?

  • How to secure Ubuntu for a non-technical user? (your mom)

Also enabled SSH so I can intervene but I am worried that I might not be in a position to do so. Possible threats: web browsing USB sticks insecure networks prone to intrusions malware SSH/VNC vulnerabilites Skype vulnerabilities All the "securing Ubuntu" guides out there assume the user has a certain level of technical knowledge but this is not the case with moms in general. If a malware can gain even user level access it might compromise her files.

  • What are the pros and cons of a non-fixed-interval update loop?

    - by akonsu
    I am studying various approaches to implementing a game loop and I have found this article. In the article the author implements a loop which, if the processing falls behind in time, skips frame renderings and just updates the game in a loop (the last variant called "Constant Game Speed independent of Variable FPS"). I do not understand why it is acceptable to call update_game() in a loop without making sure the update function is called at a particular interval. I do not see any value in doing this. I would think that in my game I want to be sure the game is updated periodically with a known period. So maybe it is worthwhile to have two threads, one would call update periodically, and the other one would redraw the game, also periodically? Would this be a good and practical approach? Of course I would need to synchronise the threads.
