  • Home – Prepaid Wireless Internet Access – The frequent and occasional traveler requiring access to the Internet knows the problem: You are there, your notebook is there but no Wifi hotspot. But don't despair. 2G and 3G cellular operators in some countries offer wireless Internet access using GPRS/EDGE/UMTS via prepaid SIM cards. <br />
    For outsiders, it's a bit difficult to find out if such an offer is available at the destination. This Wiki aims to help finding such offers. The search the Wiki for a particular country, enter its name in the search dialog box on the left. In case you travel to countries for which you can't find a local offer, take a look at Vodafone WebSessions, which can be used to access the Internet in most European countries and also some countries elsewhere with a prepaid card for a daily fee.<br />

  • FYI :: Operating Systems Release History :: Software Development … – Last updated: June 21, 2005<br />
    <br />
    The release history (below) includes the published dates (E&OE) when the vendor will withdraw product availability and support for various released versions of their respective operating systems. Knowing these dates in advance helps customers (e.g., system administrators) to plan and make informed IT decisions (such as operating system upgrades, software and hardware purchases, etc.).<br />
    <br />
    Similarly, application developers can respond proactively through adaptive maintenace, or at least be aware of (and thus, anticipate) inquiries about migration (e.g., environment differences), compatibility (e.g., APIs), and porting (e.g., 32-bit to 64-bit).<br />
    <br />
    Disclaimer: Please check with the vendor's web site for updates and program details (e.g., support options, service level, geographical differences, etc.).<br />

  • newswall is a tool to display feeds and e-mails. – Just like on a "news wall" all messages – sorted by date and time – show up in small blocks, if possible together with an image. That way it is easy to find the most important and interesting news and then have a closer look at these. So it is sort of a feed reader mixed with an e-mail viewer having the look of an image gallery. Or so… Might also be a good choice for the iPad – and other tablets, too 😉 […]<br />

  • How to build your own CDN using BIND, GeoIP, Nginx, Varnish | UNIXy – In this article, we shall outline the steps required to build a private Content Delivery or Distribution Network (CDN) using a VPS with Varnish Cache and Nginx. The goal is to build a CDN using free, readily available software but most importantly spend the least amount of funds possible. To this end, all nodes participating in this network are going to be virtual machines (Xen, Virtuozzo, OpenVZ, etc). Should you have any questions or comments on the configuration of this CDN, please post them in this forum: http://www.varnish-cache.info/
  • Comandi testuali per i sistemi Windows – […] Al lavoro, spesso mi capita di dover eseguire le stesse operazioni su più server, più volte alla settimana. La maggior parte di queste operazioni riguardano utilità di sistema di Windows, come la gestione utenti di Active Directory, o quella del DNS od altro ancora. Certo, un collegamento sul desktop è comodo, ma in talune situazioni può tornare decisamente comodo (e più veloce) conoscere il nome degli eseguibili relativi ad un determinato pannello MMC, piuttosto che l’apposita applicazione contenuta nel Pannello di Controllo.<br />
    <br />
    Quello che segue è un elenco della maggior parte di questi comandi, tutti lanciabili direttamente dal pannello “Esegui” situato nello Start Menu di Windows. Alcuni di questi comandi possono essere distruttivi, portando addirittura alla formattazione del disco ed alla conseguente perdita di dati, per cui usateli solo se ritenete di essere in grado di farlo […]

  • pwnat – NAT to NAT client-server communication – pwnat, pronounced "poe-nat", is a tool that allows any number of clients behind NATs to communicate with a server behind a separate NAT with *no* port forwarding and *no* DMZ setup on any routers in order to directly communicate with each other. The server does not need to know anything about the clients trying to connect.

  • Unix File and Directory Permissions and Modes – Unix and Linux systems (including Mac OS X and other POSIX compliant systems) have a (relatively) simple system for controlling access to files and directories. This system is defined in POSIX.1:2008 standard external link, also known as the Single Unix Specification (SUS version 4). And since devices such as disks, ports, etc. have file names (under /dev) you control access to them the same way. (Note Windows systems up through Windows ME don't support permissions, just a "read only" attribute.)

Apro l’aggregatore stamattina sul tram e leggo un post di dot-coma con la notizia che in Estonia, dopo aver coperto il 100% del territorio via WiFi, ha cominciato il progetto per posare fibra ottica in modo da dare i 100mbps a tutti i cittadini entro il 2015.

Poi arrivo in ufficio e vedo il video segnalato da Stefano:

e non riesco a fare a meno di pensare che certe cose succedono nei paesi meno fortunati di noi.
