• X crashes and GNOME loses all its configuration

  - by Oli

  About every 3 days on my desktop (always on), X crashes, gdm restarts and it dumps me at a login screen. When I log in Gnome appears to have lost a lot of its settings: it plays sounds in weird places, UI elements look like they're from the 90s (GTK+ defaults) and it's generally pretty hideous. Note everything works fine. It's not like my profile doesn't exist because I can browse the internet fine (Firefox knows my bookmarks, history, passwords, etc) and my desktop is unscathed (apart from the icon theme). Manually restarting gdm doesn't fix this. I have to do a full reboot. Now I'm almost certain that this is a nvidia issue causing X to baulk (I've seen similarish threads on nvnews) and I'm happy with that (my fault for running their latest drivers all the time). What I'm concerned about is why Gnome looks so fugly. Is there anything I can do to force it to reload its settings without restarting the whole computer. Restarting is an issue for me as I run several daemons that other computers on the network depend upon. This is what I mean by ugly/fugly... Look at that scroll bar!

• Will I be able to get programming interviews at good software companies with a non-CS degree?

  - by friend

  I'll be graduating in a year, but I'll have a degree in Economics. I'm pretty much done with my Economics coursework, and by the time next year comes around I will have devoted 1.5 years to learning CS. I will have almost finished the requirements to graduate with a degree in CS, but unfortunately my school requires a science series that would add another 6-9 months of study if I were to try and get the degree (not to mention a max unit cap). I have or will have taken: Objected Oriented Programming Discrete Math Data structures Calculus through multivariable (doubt this matters at all) Linear Algebra (same) Computer Organization Operating Systems Computational Statistics (many data mining projects in R) Parallel Programming Programming Languages Databases Algorithms Compilers Artificial Intelligence I've done well in the ones I've taken, and I hope to do well in the rest, but will that matter if I can't say to the HR people that I have a CS degree? I'd be happy to get an internship at first too, so should I just apply as if I'm an intern and not looking for fulltime, and then try and parlay that into something? Sidenote if you have time -- Is a computer networks or theory of computation class important? Would it be worth taking either of those in lieu of a class on my list? edit -- I know this isn't AskReddit or College Confidential; I know there will be some outrage at posting a question like this. I'm merely looking for insight into a situation that I've been struggling with, and I think this is the absolute best place to find an answer to this question. Thanks.

• REST API wrapper - class design for 'lite' object responses

  - by sasfrog

  I am writing a class library to serve as a managed .NET wrapper over a REST API. I'm very new to OOP, and this task is an ideal opportunity for me to learn some OOP concepts in a real-life situation that makes sense to me. Some of the key resources/objects that the API returns are returned with different levels of detail depending on whether the request is for a single instance, a list, or part of a "search all resources" response. This is obviously a good design for the REST API itself, so that full objects aren't returned (thus increasing the size of the response and therefore the time taken to respond) unless they're needed. So, to be clear: .../car/1234.json returns the full Car object for 1234, all its properties like colour, make, model, year, engine_size, etc. Let's call this full. .../cars.json returns a list of Car objects, but only with a subset of the properties returned by .../car/1234.json. Let's call this lite. ...search.json returns, among other things, a list of car objects, but with minimal properties (only ID, make and model). Let's call this lite-lite. I want to know what the pros and cons of each of the following possible designs are, and whether there is a better design that I haven't covered: Create a Car class that models the lite-lite properties, and then have each of the more detailed responses inherit and extend this class. Create separate CarFull, CarLite and CarLiteLite classes corresponding to each of the responses. Create a single Car class that contains (nullable?) properties for the full response, and create constructors for each of the responses which populate it to the extent possible (and maybe include a property that returns the response type from which the instance was created). I expect among other things there will be use cases for consumers of the wrapper where they will want to iterate through lists of Cars, regardless of which response type they were created from, such that the three response types can contribute to the same list. Happy to be pointed to good resources on this sort of thing, and/or even told the name of the concept I'm describing so I can better target my research.

• Introducing RedPatch

  - by timhill

  The Ksplice team is happy to announce the public availability of one of our git repositories, RedPatch. RedPatch contains the source for all of the changes Red Hat makes to their kernel, one commit per fix and we've published it on oss.oracle.com/git. With RedPatch, you can access the broken-out patches using git, browse them online via gitweb, and freely redistribute the source under the terms of the GPL. This is the same policy we provide for Oracle Linux and the Unbreakable Enterprise Kernel (UEK). Users can freely access the source, view the commit logs and easily identify the changes that are relevant to their environments. To understand why we've created this project we'll need a little history. In early 2011, Red Hat changed how they released their kernel source, going from a tarball that had individual patch files to shipping the kernel source as one giant tarball with a single patch for all Red Hat-introduced changes. For most people who work in the kernel this is merely an inconvenience; driver developers and other out-of-kernel module developers can see the end result to make sure their module still performs as expected. For Ksplice, we build individual updates for each change and rely on source patches that are broken-out, not a giant tarball. Otherwise, we wouldn’t be able to take the right patches to create individual updates for each fix, and to skip over the noise — like a change that speeds up bootup — which is unnecessary for an already-running system. We’ve been taking the monolithic Red Hat patch tarball and breaking it into smaller commits internally ever since they introduced this change. At Oracle, we feel everyone in the Linux community can benefit from the work we already do to get our jobs done, so now we’re sharing these broken-out patches publicly. In addition to RedPatch, the complete source code for Oracle Linux and the Oracle Unbreakable Enterprise Kernel (UEK) is available from both ULN and our public yum server, including all security errata. Check out RedPatch and subscribe to [email protected] for discussion about the project. Also, drop us a line and let us know how you're using RedPatch!

• How to work as a team of two

  - by Ezi

  I work in a team of 2 developers, my partner is the founder of the company, in the beginning he did everything on his own. He hired me about 3 years ago to help him get things done quicker and satisfy our customer needs. Often I get small project to do all by my own, as long as it works great (and it usually does...) he doesn't care much on what I did or how I did it. But if the customer calls him up asking why something doesn't work as expected and I'm not around to forward the call to me, he could get very angry on why he doesn't have an idea on how that program works. I don't keep anything as a secret, if he asks me on something how I did it I'm happy to explain as long as he's willing to listen (which isn't long), but I don't know why I need to say it in first place, in developing software everything is written down clearly. Most of the time I work on projects he wrote and I don't need to ask him anything (it happens maybe once a month that I ask him how something works, just because I don't have the time to look it up). I've read a lot on that great site about small teams that usually means 7-12 people. I couldn't find how 2 people work as a team; we don't have project managers, reviewers or testers. I feel that the fact he don't have time to review the code on his own is not my problem, so the question here is am I doing something rung? I need to walk over to him and give him a lecture on what I did even he doesn't ask me?

• Noise Canceling Earphones

  - by Mark Treadwell

  I travel a lot. The hours spent droning through the sky can be made more tolerable with an MP3 player and a set of noise-cancelling headphones. Reducing the sound of the airflow and engines is a great relief. For a year or two, I used a pair of folding Sony MDR-NC5 Noise Canceling Headphones, the ear foam covers self-destructed. I replaced them with old washcloth material and was happy, but the DW thought it looked bad.  I switched to a new set of Sony MDR-NC6 Noise Canceling Headphones.  These worked equally well, although they did not fold as small as the MDR-NC5 headphones. Over four years of use, the MDR-NC6 headphones started cutting out and making popping noises.  This was not surprising considering the beating they took on travel in my backpack.  It looked like I needed another new set. The older MDR-NC5 headphones were still on the shelf with the hated washcloth covers.  A quick search online showed a vibrant business in selling replacement ear foams, often at exorbitant prices.  Nowhere did I see ear foam covers made for the oblong MDR-NC5.  I then realized that foam is stretchable and that the shape should not matter.  After another search and some consideration, I purchased 2-5/16" foam pad ear covers that were able to stretch over the MDR-NC5's strange shape.  Problem solved for less than $5.

• Default mount options on auto-mounted NTFS partitions (how to add `noexec` and `fmask=0111`?)

  - by jetxee

  I use auto-mounting of external USB devices, and it works as expected, except that NTFS partitions are mounted with executability flag on. For example: /dev/sdb1 on /media/Elements type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions) All normal files are -rwxrwxrwx on this partition. I am not happy with the xs. I know I can have it mounted the way I want if I pass the fmask=0111 option. Now I use Lucid, and suppose it uses some new auto-mounting mechanism (gvfs-mount?), but I don't really know how the default mounting options can be changed now. Gconf settings in /system/storage/default_options/ntfs/mount_options have no effect. So, how do I make fmask=0111 the default automounting option for all NTFS partitions? (I'd be grateful also if someone explains how the current automounting mechanism works, how to configure it, and if the default mounting options are hard-coded, what I have to recompile to change them). I know that I can put a line in the /etc/fstab and/or mount manually, but this is not the solution I want, because 1) I don't want to edit /etc/fstab for each and every external drive I use, 2) fstab records appear in the Places pane of Nautilus, even if the drives are not present. The questions is how to change the defaults.

• Customer Reviews on Company Listings [closed]

  - by GSTAR

  I'm not sure if this is the right place but I am after some general advice on a feature I am looking to implement on my website. The website I have is a Wedding Directory. Here, companies can advertise in the form of a directory listing. This listing contains the company details - such as what they do and how you can contact them. There are three packages available - Basic package is free and Silver and Gold packages are charged for. Now in order to further enhance the directory, I want to enable customer reviews for each listing. This is basically whereby customers who have used a particular company's service can write a review (and rate out of 5) of their experience. The dilemma I face is that if customers are to be paying for their listings then surely they will expect to not have content on their listing that would tarnish their reputation (i.e. negative reviews). But at the same time I want to be impartial and help my site visitors to make informed choices on which companies to book when arranging their weddings. Of course I will exercise my ability to remove offensive or fake reviews but I do not want to be removing reviews just to satisfy my clients. Suppose a client pays me a premium fee to have their listing on my front page and at the top of the listings. Now suppose that client gets lost of negative reviews - the fact that they have increased visibility means that they will also get increased bad publicity. This in turn means they won't renew their package and will most likely request the listing to be taken down. So, how can I get the right balance here and keep everyone happy?

• Is there an alternative to the term "calling object"?

  - by ybakos

  Let's suppose you've got a class defined (in pseudocode): class Puppy { // ... string sound = "Rawr!"; void bark() { print(sound); } } And say, given a Puppy instance, you call it's bark() method: Puppy p; p.bark(); Notice how bark() uses the member variable sound. In many contexts, I've seen folks describe sound as the member variable of the "calling object." My question is, what's a better term to use than "calling object?" To me, the object is not doing any calling. We know that member functions are in a way just functions with an implicit this or self parameter. I've come up with "receiving object," or "message recipient," which makes sense if you're down with the "messaging" paradigm. Do any of you happy hackers have a term that you like to use? I feel it should mean "the object upon which a method is called" and TOUWAMIC just doesn't cut it.

• New functionality in TFS Build Manager &ndash; Managing Triggers and Build Resources

  - by Jakob Ehn

  Yesterday we pushed out a new release (August 2012) of the Community TFS Build Extension, including a new version of the Community TFS Build Manager (1.0.4.6) The two big new features in the Build Manager in this release are: Set Triggers It is now possible to select one or more build definitions and update the triggers for them in one simple operation: You’ll note that we have started collapsing the context menu a bit, the list of commands are getting long! When selecting the Trigger command, you’ll see a dialog where the options should be self-explanatory: The only thing missing here is the Scheduled trigger option, you’ll have to do that using Team Explorer for now.   Manage Build Resources The other feature is that it is now possible to view the build controllers and agents in your current collection and also perform some actions against them. The new functionality is available by select the Build Resources item in the drop down menu: Selecting this, you’ll see a (sort of) hierarchical view of the build controllers and their agents: In this view you can quickly see all the resources and their status. You can also view the build directory of each build agent and the tags that are associated with them. On the action menu, you can enable and disable both agents and controllers (several at a time), and you can also select to remove them. By selecting Manage, you’ll be presented with the standard Manage Controller dialog from Visual Studio where you can set the rest of the properties. Hopefully we’ll be able to implement most of the existing functionality so that we can remove that menu option Our plan is to add more functionality to this view, such as adding new agents/controllers, restarting build service hosts, maybe view diagnostic information such as disk space and error logs.   Hope you’ll find the new functionality useful. Remember to log any bugs and feature requests on the CodePlex site. Happy building!

• Eclipse will not install Android Support Package [migrated]

  - by Michael Mossman

  I am an experienced programmer but new to Android, hence using Eclipse for the first time. Unfortunately I cannot get my first project off the ground. I get as far trying to create the project when the following sequence happens. A screen arrives titled 'Install Dependencies' telling me that the required version is 8 and the installed version is 'Not installed' I click on the Install/Upgrade button and something must happen because Android SDK Manager pops up and I get a whole series of 'Fetching:' messages. The next screen asks me to Choose Package to Install and the only option is Android Support Library, revision 10. This doesn't bother me as I presume 10 is better than 8 so I hit the Install button. This is where it all goes wrong as I get a red message saying: File not found: C:\Program Files (X86)\Android\android-sdk\temp\support_r10.zip (Access is denied). Sure enough, when I check this folder, it is empty. Now, something must have happened as as SDK Manager did a whole lot of fetching and must have put these files somewhere. I am quite happy to find them and put them in the correct folder but the question is what is the name of the files that I am looking for?

• How to better explain complex software process in software specs?

  - by Lostsoul

  I'm really struggling with my software specs. I am not a professional programmer but enjoy doing it for fun and made some software that I want to sell later but I'm not happy with the code quality. So I wanted to hire a real developer to rewrite my software in a more professional way so it will be maintainable by other developers in the future. I read and found some sample specs and made my own by applying their structure to my document and wanted to get my developer friend to read it and give me advice. After an hour and a half he understood exactly what I was trying to do and how I did it(my algorithms,stack,etc.). How can I get better at explaining things to developers? I add many details and explanations for everything(including working code) but I'm unsure the best way I can learn to pass detailed domain knowledge(my software applies big data, machine learning, graph theory to finance). My end goal is to get them to understand as much as possible from the document and then ask anything they do not understand, but right now it seems they need to extract alot of information from me. How can I get better at communicating domain knowledge to developers?

• How you choose your first job as a programmer? [on hold]

  - by sliter

  For Brief I am a recently graduated CS student. I am looking for a job these days, but I have no idea what kind of software development jobs I like(embedded system,web development or else...). And I am looking for your advice. Here is a little more While I was a student, I had an one year internship experience as a system engineer in a semi-conductor company where I wrote Linux driver, tuned system performance, etc.. I was happy about this experience as it allowed me to deepen my understanding of the operating system and different low level things. And I thought "Em, I will continue in the embedded area after I graduate". At the end of my study, I am doing an another internship in web development, both front-end and back-end. And I also enjoys a lot the process of learning new things and making it work (Backbone, Node, socketio, etc..). Now, when I am looking for a software development position, I do not know what to apply! All I know is that I want a job which allows me to keep up with the trends instead of repeating. But besides this, I've no idea what specific type of job I want to do. Turn back to embedded system? Continue with web development? Change to other promising areas(data mining)? All these development positions makes no big difference to me. But I think this is not good and I need some criteria at choosing. So I am looking for advice and I would really appreciate if you can share your experience.

• Vote for bugs which impact you!

  - by Sveta Smirnova

  Matt Lord already announced this change, but I am so happy, so want to repeat. MySQL Community Bugs Database Team introduced new button "Affects Me". After you click this button, counter, assigned to each of bug reports, will increase by one. This means we: MySQL Support and Engineering, - will see how many users are affected by the bug. Why is this important? We have always considered community input as we prioritize bug fixes, and this is one more point of reference for us. Before this change we only had a counter for support customers which increased when they opened a support request, complaining they are affected by a bug. But our customers are smart and not always open support request when hit a bug: sometimes they simply implement workaround. Or there could be other circumstances when they don't create a ticket. Or this could be just released version, which big shops frighten to use in production. Therefore, sometimes, when discussing which bug to prioritize and which not we can not rely only on "Affects paying customers" number, rather need to make guess if one or another bug can affect large group of our users. We used number of bug report subscribers, most recent comments, searched forums, but all these methods gave only approximation. Therefore I want to ask you. If you hit a bug which already was reported, but not fixed yet, please click "Affects Me" button! It will take just a few seconds, but your voice will be heard.

• Top down or bottom up approach?

  - by george_zakharov

  this is the closest I think I can get to define my problem. I'm an interface designer and now I'm working with a team of programmers to develop a new CMS for a heavy media site. I'm sorry if it's a very, very dumb question to ask here, but I really need some help. As I've started developing a specification list for a prototype it turned out a very big one. I do realize now that the client-side will be JS heavy, with lots of DnD and other "cool designer stuff". The CMS will even include a small project management system for its users, nothing big like Basecamp, but with a live feed of comments etc. The problem is the the team has now separated. Someone is proposing the existing backend solution used in other CMS, someone is proposing to rewrite everything from scratch. The point to keep the code is that it is faster, the point to rewrite is to make it better for the proposed design (include Node.js and other stuff I don't actually get). The question is — can the UI specs influence back-end? The guys that propose to use the existing solution did everything with the Yii framework (as far as I know), and they say that everything on server is not affected by this "interface coolness". Others say that it does, that even autosave can't work without server load. Please, if this is really incomprehensible, again, I'm sorry, and I'll happy to clarify it after your questions. Thanks in advance

• VPNs - The ins and outs of IPSec & VPNs in general [on hold]

  - by Magus

  I have to decided to mess around with VPNs on my home router, to access a couple of servers in the back room of my house, however, I went into this thinking happy thoughts and easy-peasy-lemon-squeezy... Now I feel like doing drugs, as if maybe that will help me understand the myriad of terms which come with this nifty little tool. Basically, I do understand WHAT a VPN is, but I have no idea how to set one up. I have a Cisco router ( will supply more info if needed ), and would prefer to use IPSec for this ordeal. I'd like to have the following terms explained ( and yes, I have used the famous Google to help, close but no cigar ) : "Local Secure Group", "Remote Secure Group", "Remote Secure Gateway", how different types of "Keys" work ( again, I know the basics ), and for the "Add VPN Config" screen on the connecting device: "Server, does it have to be an address, or just an IP?", "Account; is this the tunnel name?", I am going to assume 'Password' means the Key, "Group Name; or is THIS the tunnel name?", and "Secret; I halfish know what this is..." I would really appreciate any contribution made, no matter how small, even if it includes a redirect. I just want to learn. Thanks in advance! Magus

• OBIEE Capacity Planning

  - by THE

  I can not even recall how many times I was asked by a customer what size the machine should be bought to run our Software. Unfortunately Tech Support is not even the right address to answer that question, as a purchase decision is closely tied to the answer. Hence, Tech Support has been limited to the answer: "The biggest machine you can afford" . Many Customers were unhappy with that and have tried to get us to be more precise and that causes a lot of explanation and lengthy discussion. In the end no one is wiser or happier.  Therefore I am happy to report that at least for OBIEE the decision has just been made a whole lot easier. Have a look at the note Oracle BI EE 11g Architectural Deployment: Capacity Planning (Doc ID 1323646.1) The document attached to that note gives you a good overview for teh sizing of the machines that Oracle recommends to run OBIEE (be it a small installation or a bigger distributed installation) If you have any more questions about this topic and what machines we recommend, then get in contact with  Oracle Consulting or speak to your sales representative.

• Transferring users and search engines to a new domain

  - by eftpotrm

  I've been asked to take over the maintnance of an existing site that's being reworked. At present it's serving localised content for several languages, but via a fairly unhelpful mechanism that means essentially search engines only have it indexed in English and any deep links will de facto appear in English as well. So, new localised sites are being built under separate domains - not just for this, there's other benefits. What we're then looking to do is to redirect users correctly to the new site, where appropriate. For humans this isn't a problem. We can send them through a gateway page on their first site visit, grab their language preference and put it in a cookie, then redirect them to the new localised content as soon as it's available. For search engines, this isn't so good... In principle I'm happy to simply bypass the gateway page and redirect known spiders to the new site, but this means we're serving radically different content (different URL even!) to human and robot users. Won't this therefore be regarded as cloaking and cause us grief? Anyone know a better way to handle this?

• How do I make my customers not like me too much?

  - by fuzzbone

  In 2004 I went to work for a consulting firm because I like variety, challenges, working with new technologies, etc. However, I've been a developer for 25 years - and spent the majority of my career as a direct-hire (12 years) then as an independent consultant for another 3 years (ah the DotCom bubble!) for one firm. So my instincts are more like a good internal developer than a consultant. My problem is what I call the "catch-22" of consulting. You go into consulting because you want to work at a lot of different engagements, but if you do a really good job your clients never want to let you go. And of course the salespeople are happy to keep you billing (and don’t want to alienate a good customer) So my question is – how do I overcome this? I have had some colleagues who had just the right type of “arrogance” (for lack of a better term) that made them initially attractive to some clients, but would grate on them over time – but that just isn’t my style. I want to do good work and be successful for my clients, but be able to “gracefully” move on after a reasonable amount of time.

• Website only displays correctly in IE using compatibility mode?

  - by user21318

  As the resident "IT Whiz" at work (ie: I know how to use a computer) I've been asked to develop a website for our small business. I've altered a wordpress theme for the time being and the company is very happy with the results. The only problem I am having with it at the moment is that for some reason the website does not display correctly and Internet Explorer unless I run it in Compatibility Mode. The main problem that I have is that my menu "slider" (it rotates pictures with links to articles etc) does not display at all, neither does the top menu they are just blink text based links. Even with Compatibility Mode enabled the slider and menus come back but the page is not centered unlike on both Firefox and Chrome. My googling has suggested the most common cause of this is old code but I'm not sure where to be looking. Is it likely in the css file or the actual php? Also any ideas on how to trouble shoot the cause of this? As in is there some dev tools or debugger I can use that would highlight "broken" code for me?

• How can I install Ubuntu's 10.10 kernel I Ubuntu 12.10?

  - by user103533

  I did use Ubuntu 10.10 for a long time, and now I replaced it with Ubuntu 12.10, every thing works great, but I do have one little problem, which is with my wireless card. On Ubuntu 10.10, it worked PERFECTLY, and it even worked better than in windows 7, so I was very happy with Ubuntu 10.10, but, like I said, after installing 12.10, my wireless card doesn't work any more, so I heard that KERNELS are the reason for that. Are kernels the reason for my wireless not working now? If yes then please teach me how to remove my current kernels and install 10.10 kernels. I went to -Additional Drivers- and i found something very weird i took picture and this is what it look like "apply changes" Button NOT active so i can't install driver :( anyway... my Wireless card is WL-138g v2 (remember on Ubuntu 10.10 it was WORKING 100% normally and FREE i did NOT pay for it driver) so... now what shall i do ? it is saying in picture // Using Non-Free firmware for linux kernel drivers from linux-firmware-nonfree (proprietary) // BTW i did "rfkill list" but NO-thing appear under that command.

• SQL Server 2012 Express LocalDB &ndash; How to get started

  - by krislankford

  As many of you aware, SQL Server can be a bit of a pig when it comes to system resources on your development machine. As part of the 2012 products Microsoft has added SQL Server 2012 Express LocalDB which is a happy medium for myself when thinking about having to install a full blown SQL Server on my box. This however does not work in all cases for all development but if you are doing web or local client development then it should suffice. On the other hand, if you are working with technologies like SharePoint or trying to run Team Foundation Server on your local box then you will be out of luck while using LocalDB. To start of with, the localDB setup is delivered and packaged with Visual Studio 2012 RC. If you want to get the stand-alone installer you can download it here in either the 32 or 64 bit flavors. Once you get it installed you can start using it right away in either Visual Studio 2010 or the new Visual Studio 2012 RC. To get started you can open the SQL Server object explorer in Visual Studio by clicking   the menu option View –> SQL Server Object Explorer. This will bring up to the navigation pane where you can add a SQL Server. Once you add the SQL Server you will be prompted with the “Connect to Server” dialog to enter the server for which you can use “(localdb)\v11.0”. Click connect and you should be connected to your localDB where you can create and manage databases from Visual Studio 2010, Visual Studio 2012 or SSMS. Once you have started creating databases here you can use the database projects in Visual Studio with these database as well as use the (localdb)\v11.0 server name inside your connections string information for your development environment. Hope this helps someone get started with SQL Server 2012 Express LocalDB! It provides a great balance for developing against SQL Server 2012.

• How can I get better at explaining complex software processes to developers?

  - by Lostsoul

  I'm really struggling with my software specs. I am not a professional programmer but enjoy doing it for fun and made some software that I want to sell later but I'm not happy with the code quality. So I wanted to hire a real developer to rewrite my software in a more professional way so it will be maintainable by other developers in the future. I read and found some sample specs and made my own by applying their structure to my document and wanted to get my developer friend to read it and give me advice. After an hour and a half he understood exactly what I was trying to do and how I did it(my algorithms,stack,etc.). How can I get better at explaining things to developers? I add many details and explanations for everything(including working code) but I'm unsure the best way I can learn to pass detailed domain knowledge(my software applies big data, machine learning, graph theory to finance). My end goal is to get them to understand as much as possible from the document and then ask anything they do not understand, but right now it seems they need to extract alot of information from me. How can I get better at communicating domain knowledge to developers?
