Correcting Poor Typing Technique? 425

An anonymous reader writes "When beginning to use keyboards I did not pay much attention to touch typing technique. Instead, I eventually achieved decent rates by simply doing what felt natural to me. These days my qwerty typing speed is in the range of 90-110 WPM, probably more toward the lower end. While this isn't too shabby, I feel some awkwardness in my technique (such as not using my little and ring fingers when I really should). Has anyone been in a similar situation, wanted to fix it, and actually done so? What do you reckon is the best way to fix half-broken typing? Touch training sessions? Should I switch to Dvorak and pretty much learn typing from scratch, but properly this time?"
Security

Coping With 1 Million SSH Authentication Failures? 497

An anonymous reader writes "I own a small Web development studio that specializes in open source software, primarily Drupal, WordPress, and Joomla for small businesses. Our production servers, which host about 50 sites and generate ~20K hits/week, are managed by a 3rd party that I'm sure many on Slashdot would recognize. Earlier today I was researching some problems on one of our sites and found that there have been over 1 million SSH authentication failures from ~1200 IP addresses on one of our servers over the last year. I contacted the ISP, who had promised me that server security would be actively managed, and their recommendation was, 'change the SSH port!' Of course this makes sense and may help to an extent, but it still doesn't solve the problem I'm facing: how do you manage server security on a tight budget with literally no system admin (except for me and I know I'm a n00b)? User passwords are randomly generated, we use a non-standard SSH port, and do not use any unencrypted services such as FTP. Is there a server monitoring program you would recommend? Is there an ISP or Web-based service that specializes in this?"

Best WAP For Dense Crowds? 178

An anonymous reader writes "A local community organization has asked me to help them set up Wi-Fi access for an upcoming event, with some unusual (to me) requirements. All users (up to 500 people) will occupy a relatively small area and more-or-less have line-of-sight to the WAP, so issues like signal strength and wall penetration don't matter. Security also does not matter, as we plan to open this to anyone wanting to connect. Cost always matters, but we realize a $50 Linksys or three won't cut it here. In the past, I have used Cisco AP1200s for a few dozen users to great satisfaction, but they only handle 50 connections at a time, and practically count as antiques at this point anyway. My research on the matter tells me that 802.11n performs far better in this regard, but I want to support 802.11g as well. I have no objection to using two APs to split those apart (with n limited to 5.8GHz, as per the suggestion of several comments in a recent Ask Slashdot), but physical constraints make it preferable to minimize the total number of APs needed — Ten WRT54s might cost about the same as one Aironet, but I only have three good places to mount these. I welcome any suggestions and real-world experiences with similar situations, including the ever-popular Ask Slashdot refrain of 'What kind of idiot would do it like that, when you can just do this?' Ideally, I would like to know model numbers and how well they held up under real-world loads comparable to my situation."

Throttle Shared Users With OS X — Is It Possible? 403

whisper_jeff writes "I work in a design studio where the production director is also the owner's son (translation = he can do no wrong). He is fond of accessing a designer's computer via filesharing and working directly on files off of the designer's computers rather than transferring the files to his computer to work on them there. In so doing, he causes the designer's computer to grind to a near-halt as the harddrive is now tasked with his open/save requests along with whatever the designer is doing. Given that there is no way he's going to change his ways (since he doesn't see anything wrong with it...), I was wondering if there was a way to throttle a user's shared access to a computer (Mac OSX 10.5.8) so that his remote working would have minimal impact on our work. Google searches have revealed nothing helpful (maybe I should Bing it... :) so I was hoping someone with more technical expertise on Slashdot could offer a suggestion."

A Public Funded "Microsoft Shop?" 490

An anonymous reader writes "I work at a public hospital in the computer / technical department and (amongst others) was recently outraged by an email that was sent around our department: '(XXXX) District Health Board — Information Services is strategically a Microsoft shop and when talking to staff / customers we are to support this strategy. I no longer want to see comments promoting other Operating Systems.' We have also been told to remove Firefox found on anyone's computer unless they have specific authorisation from management to have it installed under special circumstances. Now, I could somewhat understand this if I was working in a company that sold and promoted the use of Microsoft software for financial gain, but I work in the publicly / government funded health system. Several of the IT big-wigs at the DHB are seemingly blindly pro-Microsoft and seem all too quick to shrug off other, perhaps more efficient alternatives. As a taxpayer, I want nothing more than to see our health systems improve and run more efficiently. I am not foolish enough to say all our problems would be solved overnight by changing away from Microsoft's infrastructure, but I am convinced that if we took less than half the money we spend on licensing Microsoft's software alone and invested that in training users for an open source system, we would be far better off in the long run. I would very much like to hear Slashdot's ideas / opinions on this 'Strategic Direction' and the silencing of our technical opinions."
Data Storage

Long-Term Storage of Moderately Large Datasets? 411

hawkeyeMI writes "I have a small scientific services company, and we end up generating fairly large datasets (2-3 TB) for each customer. We don't have to ship all of that, but we do need to keep some compressed archives. The best I can come up with right now is to buy some large hard drives, use software RAID in linux to make a RAID5 set out of them, and store them in a safe deposit box. I feel like there must be a better way for a small business, but despite some research into Blu-ray, I've not been able to find a good, cost-effective alternative. A tape library would be impractical at the present time. What do you recommend?"
Data Storage

Write Bits Directly Onto a Hard Drive Platter? 578

kidcharles writes "I'm working on a project that requires writing bits to a magnetic hard drive platter in a completely controlled fashion. I need to be able to control exactly where 1s and 0s will appear physically on the platter. Normally when data is written to a drive the actual bits that get written are determined by the file system being used, as modified by whatever kind of error handling the drive itself is using (e.g. Reed-Solomon). All of the modern innovations in file systems and error handling are great for reliable and efficient data storage, but they are making my particular task quite daunting. My question for Slashdot: is there a way to get down to the 'bare metal' and write these bits? Any good utilities out there to do this? Obviously a free and open source solution would be preferable, but I'm open to anything at this point."
GUI

How Do You Get Users To Read Error Messages? 951

A BOFH writes "The longer I do desktop support, the more it becomes obvious that my users don't read anything that appears on their screen. Instead, they memorize a series of buttons to press to get whatever result they want and if anything unexpected happens, they're completely lost. Error logs help a lot, but they have their limits. I've been toying with a few ideas, but I don't know if any of them will work and I was hoping my fellow Slashdotters could point me in the right direction. For example, I was thinking about creating icons or logos to identify specific errors. They might not remember that an error is about 'uninitialized data' but they might be more able to remember that they got the 'puppy error' if I showed a puppy picture next to the error message. Or for times when finding images is too time consuming, you could create simple logos from letters, numbers, symbols, colors, or shapes, so you could have the 'red 5' error or 'blue square' error (or any combination of those elements). I've even wondered if it would be possible to expand that to cover the other senses, for example, playing a unique sound with the error. Unfortunately, haptic and olfactory feedback aren't readily available. I like to think that my users would remember the error that caused them to get a swift kick in the balls. And if they forgot it anyhow, I could always help them reproduce it. Does anyone else have experience with ideas like these? Did it work?"

Killer Apartment Vs. Persistent Microwave Exposure? 791

An anonymous reader writes "I am considering buying a penthouse apartment in Manhattan that happens to be about twenty feet away from a pair of panel antennas belonging to a major cellular carrier. The antennas are on roughly the same plane as the apartment and point in its direction. I have sifted through a lot of information online about cell towers, most of which suggest that the radiation they emit is low-level and benign. Most of this information, however, seems to concern ground-level exposure at non-regular intervals. My question to Slashdot is: should the prospect of persistent exposure to microwave radiation from this pair of antennas sitting twenty feet from where I rest my head worry me? Am I just being a jackass? Can I, perhaps, line the walls of the place with a tight metal mesh and thereby deflect the radiation? My background is in computer engineering — I am not particularly knowledgeable about the physics of devices such as these. Please help me make an enlightened decision."

Will the Serial Console Ever Die? 460

simpz writes "Will the serial port as a console connection ever be displaced — especially for devices such as switches, routers, SAN boxes, etc.? In one sense it's a simple connection. But it is the only current port that, in order to use, you need to know about wiring / baud rates / parity, etc. It has non-standard pinouts. And it is becoming too slow to upload firmware to dead devices, as the firmware updates get larger. Also, the serial port is rapidly disappearing from new laptops — which is where you often really need it, in data centers. Centronics, PS/2, and current loop are mostly defunct. Is there any sign on the horizon of a USB console connection?"
Cellphones

What Has Your Phone Survived? 422

NotAnIndividual writes "On an ice fishing trip two months ago, I lost my iPhone somewhere in the snow. I searched and searched, but to no avail. But just this weekend when moving the ice hut, lo and behold there it was. I quickly threw it into a bag of rice and placed it under a lamp to defrost. Three hours later I plugged it in. I wasn't expecting much. I mean, really, it had been frozen in snow for the last two months! To my surprise, the Apple logo popped up. I put in the SIM card and voila, my iPhone was back. My apps, my contacts, my music and more importantly my life were back. And this is the same iPhone that I dropped in a cup of coffee a few months ago! This got me wondering how much damage a cell phone can actually take. How have other Slashdot users punished their phones without actually killing them completely?"

Should I Take Toyota's Software Update? 750

kiehlster writes "I'm a software developer, and I know that most software has bugs, but how much trust can we put in the many lines of code found in our automobiles? I have a 2009 Camry that is involved in both of the recent Toyota recalls. As part of the floor-mat issue, they're offering to install a software update that would cause 'the brake pedal to take precedence over the gas pedal if both were pressed,' or, as their latest notice states, 'would cut power to the engine if both pedals were pressed.' In the computer world, we're all taught to install firmware updates only if there is a real problem because a large percentage of firmware updates actually brick the hardware or cause other unforeseen consequences. On a base of 100 million lines of code, can I really trust a software update to work safely when it is delivered in a three-month development cycle? My driving habits don't cause the floor mat to slide much, so I see the update as overkill. What do you think? If it doesn't void the warranty, should I tell them to skip the update?"

Health Insurance When Leaving the Corporate World? 1197

An anonymous reader writes "I've been working at a large company since I got out of college, so I didn't have to give much thought to getting my own healthcare plan. Now I'm thinking about leaving the corporate world and starting out on my own. I have a family now, so I need to make sure we're going to be covered should anything happen. Researching online turns up horror stories of people trying to get individual healthcare plans, or getting denied coverage on plans they thought they had. Does anyone else have experience going through this and what you've had to deal with, or am I making too big a deal of it?"
Games

Why Are There No Popular Ultima Online-Like MMOs? 480

eldavojohn writes "I have a slightly older friend who played through the glory days of Ultima Online. Yes, their servers are still up and running, but he often waxes nostalgic about certain gameplay functions of UO that he misses. I must say that these aspects make me smile and wonder what it would be like to play in such a world — things like housing, thieving and looting that you don't see in the most popular massively multiplayer online games like World of Warcraft. So, I've followed him through a few games, including Darkfall and now Mortal Online. And these (seemingly European developed) games are constantly fading into obscurity and never catching hold. We constantly move from one to the next. Does anyone know of a popular three-dimensional game that has UO-like rules and gameplay? Perhaps one that UO players gravitated to after leaving UO? If you think that the very things that have been removed (housing and thieving would be two good topics) caused WoW to become the most popular MMO, why is that? Do UO rules not translate well to a true 3D environment? Are people incapable of planning for corpse looting? Are players really that inept that developers don't want to leave us in control of risk analysis? I'm familiar with the Bartle Test but if anyone could point me to more resources as to why Killer-oriented games have faded out of popularity, I'd be interested."

Things To Look For In a Web Hosting Company? 456

v1x writes "I have had an account with my current web hosting company for a few years, with 3 domains being hosted there (using Linux/PHP/MySQL). Recently, all three of these websites stopped functioning, and upon checking the site, all my directory structures were intact, whereas all of the files were gone. Upon contacting their technical support, I was given the run-around, and later informed by one of their administrators that none of the files could be restored. Needless to say that I am looking for a different web hosting company at this point, but I would like to make a more informed choice than I did with the current company. I have read a similar Slashdot article (from 2005) on the topic, but the questions posed there were slightly different." Reader mrstrano has a similar question: "I am developing a web application and, after registering the domain, I am now looking for a suitable web hosting provider. It should be cheap enough so I can start small, but should allow me to scale up if the web site is successful (as I hope). The idea is simple enough so I do not need other investors to implement it. This also means that I don't have a lot of money to put on it at the moment. Users of the website will post their pictures (no, it's not going to be a porn website), so scalability might be an issue even with a moderately high number of users. I would like to find a good web hosting provider from day one, so I don't have to go through the pain of a data migration. Which web host would you choose?"

After Learning Java Syntax, What Next? 293

Niris writes "I'm currently taking a course called Advanced Java Programming, which is using the text book Absolute Java, 4th edition, by Walter Savitch. As I work at night as a security guard in the middle of nowhere, I've had enough time to read through the entire course part of the book, finish all eleven chapter quizzes, and do all of the assignments within a month, so all that's left is a group assignment that won't be ready until late April. I'm trying to figure out what else to read that's Java related aside from the usual 'This is how to create a tree. This is recursion. This is how to implement an interface and make an anonymous object,' and wanted to see what Slashdotters have to suggest. So far I'm looking at reading Beginning Algorithms, by Simon Harris and James Ross."

Fingerprint Requirement For a Work-Study Job? 578

BonesSB writes "I'm a student at a university in Massachusetts, where I have a federal work-study position. Yesterday, I got an email from the office that is responsible for student run organizations (one of which I work for) saying that I need to go to their office and have my fingerprints taken for the purposes of clocking in and out of work. This raises huge privacy concerns for me, as it should for everybody else. I am in the process of contacting the local newspaper, getting the word out to students everywhere, and talking directly to the office regarding this. I got an email back with two very contradictory sentences: 'There will be no image of your fingerprints anywhere. No one will have access to your fingerprints. The machine is storing your prints as a means of identifying who you are when you touch it.' Does anybody else attend a school that requires something similar? This is an obvious slippery slope, and something I am not taking lightly. What else should I do?"

Which Linux For Non-Techie Windows Users? 766

obarthelemy writes "Having at last gotten Linux to run satisfactorily on my own PCs, I'd now like to start transitioning friends and family from XP to Linux instead of Windows 7. The catch is that these guys don't understand or care much about computers, so the transition has to be as seamless and painless as possible. Actually, they won't care for new things; even the upcoming upgrade to Windows 7 would be a pain and a bother, which is a great opportunity for Linux. I'm not too concerned about software (most of them only need browser, IM, VLC, mail and a Powerpoint viewer for all those fascinating attachments). What I'm concerned about is OS look-and-feel and interface — system bar on the bottom with clock, trash, info on the right, menu on the left, menu items similar to those of Windows. Is it better to shoot for a very targeted distro? Which would you recommend? Are there themes/skins for mainstream distributions instead? I've been looking around the web, and it's hard to gauge which distros are well-done and reasonably active."

Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"

Suggestions For a Coax-To-Ethernet Solution? 608

watanabe writes "I just moved from a house with Cat5e wiring to a house with ... a whole bunch of coax cables. Like, my living room has five coax cables coming out of a hole in the wall. All of them go back up to my attic. The house is big, (and I like it, thank you), but I have realized that our digital usage pattern (media server + squeezeboxes + remote time machine backups to a linux box) will not work without wiring. I am currently bridging some old Linksys WRT54Gs to the right places, but of course, that slows everything down. This got me thinking: 100mb ethernet is four wires, yes? And I have four wires for every two coax cables. What about a two coax-head -> ethernet jack setup? Has anyone done this before? Searching online only gives me $100+ coaxethernet transceiver type boxes. At that price, a HomePNY system would make more sense. I'm willing to solder if I have to, but I first wanted to get advice and holes shot in my plan, if there are any."
