Ask Slashdot: Replacing a TI-84 With Software On a Linux Box? 254

Posted by Soulskill
from the can-we-get-a-modern-display-on-these-things dept.
yanom writes "I'm currently a high school student using my TI-84 for mathematics courses. It has all the functionality I need (except CAS), but saying that the hardware is dated is putting it nicely. Waiting 4-5 seconds for a simple function to be graphed on its 96x64 screen just makes me want to hurl it at the wall. Recently, I've begun to notice the absurdity of doing my math homework on a 70's era microchip when I have an i7 machine with Linux within arm's reach. I've begun looking for software packages that could potentially replace the graphing calculator's functionality, including Xcas and Maxima, but both lack what I consider basic calculator functionality — xcas can't create a table of values for a function, and maxima can't use degrees, only radians. So, does anyone know of a good software package to replace my graphing calculator (and maybe provide CAS to boot)?"

Ask Slashdot: Facebook, Twitter For Business, Is It Worth the Privacy Trade-Off? 158

Posted by samzenpus
from the give-and-take dept.
cayenne8 writes "I've been a staunch advocate of NOT joining Facebook or Twitter or the other social networks to protect my privacy and to not voluntarily give all my personal information away to corporate America, or even the Government. However, I'm beginning to look into making money through various means on the side, one of them being photography/videography. With these mediums, being seen is critically important. Having a business facing site on Facebook/Google+ and even using Twitter can be great for self promotion, and can open up your business to a huge audience. If you were to open your FB and other social network accounts with business ONLY information, and keep your personal information (name, image, etc) off the Facebook account...will this keep your personal privacy still from them, or are their algorithms good enough to piece together who you are from the business only sites? Is the payoff worth the potential trade-off for generating potential customers for your business and guiding them to your primary website?"

First time accepted submitter Uzuri writes "I'm soon going to have the experience of interviewing an individual to be my direct supervisor. I have in mind several things to ask already, especially since I also have the strange position of working as a technical person in a non-technical office and want to be able to be certain that the interviewee understands exactly what that means without coming off as hostile or condescending. What sort of questions would you ask/have you asked the person who was to be your boss? What sort of tells would you look for? What's out of bounds?"

Ask Slashdot: Where Do You Draw the Line On GPL V2 Derived Works and Fees? 371

Posted by samzenpus
from the what-do-you-think? dept.
First time accepted submitter Shifuimam writes "I downloaded a DOSBox port for Android recently to get back into all the games of my childhood. Turns out that the only free distribution available hasn't been updated in nearly two years, so I looked for alternatives. There are two on Google Play — DOSBox Turbo and "DOSBot". Both charge a fee — DOSBox Turbo is $3.99; DOSBot is $0.99. The developer of DOSBot says on his Google Play entry that he will not release the source code of his application because it's not GPL, even though it's derived from source released under GPL v2 — this is definitely a violation of the license. The developer of DOSBox Turbo is refusing to release the source for his application unless you pay the $3.99 to "buy" a license of it. The same developer explicitly states that the "small" fee (although one might argue that $3.99 is pretty expensive for an OSS Android app) is to cover the cost of development. Unless I'm misreading the text of GPL v2, a fee can only be charged to cover the cost of the distribution of a program or derived work, not the cost of development. And, of course, it doesn't cost the developer anything for someone to log in to Google Play and download their app. In fact, from what I can tell, there's a one-time $25 fee to register for Google Checkout, after which releasing apps is free. Where do you draw the line on this? What do you do in this kind of situation?"

Ask Slashdot: Current State of Linux Email Clients? 464

Posted by Soulskill
from the unfavorable-selection-pressure dept.
mcloaked writes "We get all kinds of news about new developments, but one subject has been lacking for some time and that is email clients for Linux (or Windows for that matter). A number of reviews (mostly not all that recent) have pointed to the main clients as Thunderbird, Evolution, Claws-mail, and Kmail as possibilities. Up to about a year ago, Thunderbird seemed to be 'the' email client with the best mix of positives. However there are no recent reviews that I have seen. In the meantime Thunderbird has moved to monthly releases, which are more maintenance releases containing security fixes but little functional change — and little new development. Thunderbird also won't be significantly altered in the future, if one interprets the available news information. Evolution is reported to be rather prone to bugs, and Kmail even more so. Claws-mail has limitations, as does Kmail. So where is the future of Linux email clients going, absent any real innovation? We need a well maintained and capable mail client, preferably with good calendar integration (webcal/Google calendar), properly supported HTML composing, good maildir format storage for local mail, and good security support (including the capacity to deal with both GPG and S/MIME encryption and signing). It needs a modern UI and good import/export facilities, as well as good integration with its address book, including import/export of addresses. Are we likely to see this kind of package as we move into the future, or will mail clients slowly disappear? At the moment it looks like email client support is dead — Are too many users moving into web mail and the cloud instead of having a properly functional mail client on their desktops?"

Ask Slashdot: Best Laptop With Decent Linux Graphics Support? 260

Posted by timothy
from the holy-grail-for-the-holidays dept.
jcreus writes "After struggling for some years with Nvidia cards (the laptop from which I am writing this has two graphic cards, an Intel one and Nvidia one, and is a holy mess [I still haven't been able to use the Nvidia card]) and, encouraged by Torvalds' middle finger speech, I've decided to ditch Nvidia for something better. I am expecting to buy another laptop and, this time, I'd like to get it right from the start. It would be interesting if it had decent graphics support and, in general, were Linux friendly. While I know Dell has released a Ubuntu laptop, it's way off-budget. My plan is to install Ubuntu, Kubuntu (or even Debian), with dual boot unfortunately required." So: what's the state of the art for out-of-the-box support?

New submitter thereitis writes "Looking over my home computing setup, I see equipment ranging from 20 years old to several months old. What sorts of old and new equipment have you seen coexisting, and in what type of environment?" I regularly use keyboards from the mid 1980s, sometimes with stacked adapters to go from ATX to PS/2, and PS/2 to USB, and I'm sure that's not too unusual.

Ask Slashdot: Do You Still Need a Phone At Your Desk? 445

Posted by samzenpus
from the dial-U-for-useless dept.
First time accepted submitter its a trappist! writes "When I started my career back in the early 1990s, everyone had a 'business phone' phone on their desk. The phone was how your co-workers, customers, friends and family got in touch with you during the business day. It had a few features that everyone used — basic calling, transfer, hold, mute, three-way calling (if you could figure it out). This was before personal mobile phones or corporate IM, so the phone was basically the one and only means of real-time communication in the office. Flash forward 20 years. Today I have a smart phone, corporate IM, several flavors of personal IM, the Skype client and several flavors of collaboration software including Google Apps/Docs, GoToMeeting. My wife and daughter call me or text me on the cell phone. My co-workers who are too lazy or passive aggressive to wander into my office use IM. My brother in Iraq uses Skype. I use GoToMeeting and its built-in VoIP with customers. The big black phone sits there gathering dust. I use it for conference calls a few times each month. I'm sure that there are sales people out there who would rather give up a body part than their trusty office phone, but do any of the rest of us need them? Around here, the younger engineers frequently unplug them and stick them in a cabinet to free up desk space. Are the days of the office phone (and the office phone system) at an end?"

Slashdot Asks: SATA DVD Drives That Don't Suck for CD Ripping? 330

Posted by Unknown Lamer
from the god-save-the-cd dept.
I recently retired my ancient AthlonMP rig for something a bit more modern, and in the upgrade got a new DVD±RW drive. Since I have the new rig and a lot more disk space, the time has come to re-rip my ~450 disc CD collection into FLAC (I trust active storage more than optical discs that may or may not last another twenty years). The optical drive I had in my old rig was one recommended by Hydrogen Audio or somewhere similar for ripping CDs, and can grab an hour long album in about five minutes. My new drive, unfortunately, takes about fifteen to do the same. With the number of discs I have to churn through and the near-instaneous encoding, it's somewhat annoying. After searching the Internet high and low for advice I came up empty handed, and so I ask Slashdot: are there any SATA DVD burners that don't suck at ripping CDs? Read on for more details if you wish.

Ask Slashdot: Tablets For Papers; Are We There Yet? 180

Posted by timothy
from the getting-closer-at-least dept.
An anonymous reader writes "When I was younger, engineering and science offices didn't have computers yet. It was the tradition: Piled Higher and Deeper desks, and overloaded bookcases. I ended up doing other things, and haven't been in a regular office for a couple of decades. Now I'm older, spending a lot more time with the screen, and finding my aging butt and back aren't as pliable for the long hours of reading papers. And while looking at rather expensive chairs, etc for a solution, what I'm remembering is we used to be able to lean back, feet up, while reading the stapled print-outs — makes a change from hunched-over writing and typing. So I'm what wondering is this: Are We There Yet with tablets? You guys would know — What makes a good tablet for reading, sorting, annotating, and searching PDFs, etc? Hardware and software — what tablets have gotten this really right?"

Ask Slashdot: Good Linux Desktop Environment For Hi-Def/Retina Displays? 234

Posted by Soulskill
from the time-to-start-thinking-about-this-again dept.
Volanin writes "I have been using Linux for the last 15 years both at home and at work (mostly GNOME and now Unity). Recently, I gave in to temptation and bought myself a Macbook retina 15". As you can read around, Linux still has no good support for this hardware, so I am running it inside a virtual machine. Running in scaled 1440x900 makes the Linux fonts look absolutely terrible, and running in true 2880x1800 makes them beautiful, but every UI element becomes so tiny, it's unworkable. Is there a desktop environment that handles resolution independence better? Linux has had support for SVG for a long time, but GNOME/Unity seems adamant in defining small icon sizes and UI elements without the possibility to resize them."

Ask Slashdot: DIY 4G Antenna Design For the Holidays? 135

Posted by samzenpus
from the tune-in dept.
eldavojohn writes "This holiday season I will return to the land of my childhood. It is flat and desolate with the nearest major city being a three hour car drive away. Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?"

Ask Slashdot: What Web Platform For a Small Municipality? 161

Posted by timothy
from the right-here-in-river-city dept.
First time accepted submitter r3dR0v3r writes "I have the opportunity to help improve / replace the website of my small U.S. town (~6000 people). The town leaders are open to most any suggestions, and are open to the idea of having the website facilitate a more open government — by being a place at which town documents, meeting agendas, meeting minutes, legal forms, ordinances, etc. can be found in an organized way and downloaded. And of course the site should provide general info about the town, it's services, recreation opportunities, etc.. Now, we have no budget, so we'll be looking at free/open software. I've considered options such as Drupal, but I'm doing this as volunteer work so I don't want to start from scratch and spend overly much time. Thus, I'm looking for advice about any existing platforms made specifically for municipalities as a great way to get a jump start. I'm guessing there are other slashdotters that have helped their communities in this way. Your suggestions please?"

Ask Slashdot: Server Room Toolbox? 416

jandersen writes "I am the system manager in charge of a smallish server room (~50 servers, most in racks), and I am going to buy a set of tools; but first I want to hear what other people think would be a good idea. Certainly a range of good quality screwdrivers — slotted, Phillips, Pozidriv, Torx. But what else? Tape measure? Spirit level (for aligning the racks)? Any meters or cable testers? A wood lathe? I can probably get away with a budget of a few hundred GBP, but there ought to be some mileage in that."
