It's official now. Deal will create a computer services giant intended to rival IBM in the market for serving business customers.

Bournemouth has become the first town in the UK to get super-fast internet connections - via the sewerage system. More than 88,000 homes and businesses in the Dorset town will benefit from internet speeds up to 100Mbps under the scheme, considerably faster than consumer broadband speeds on the market.

If you're running Apache2 on a memory-constrained system (like in a virtual machine,) you may want to choose the prefork MPM to save memory at the cost of more process forks. However, if you have more than one CPU on that same machine, you may also want to consider using the threaded worker MPM and tweak its MaxClients and ThreadsPerChild settings from the default configuration.

On a typical apache2 installation on a Debian system, the worker MPM configuration looks like this:

<IfModule mpm_worker_module>
    MaxClients          150
    MinSpareThreads      25
    MaxSpareThreads      75
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

Using these default settings on a resource-constrained system (say a server with 128MB of RAM but with no swap) would be overkill, and the web server processes will definitely eat up all of that memory, leaving little or no room for even simple CGI scripts.

In my setup, I experimented with tweaking the values above to get apache2 to serve without eating up too much precious memory. I found that the important values to consider here are MaxClients, which dictate how many clients can connect simultaneously to my server, and ThreadsPerChild, which specifies how many threads of execution can run in a child/worker process. My resulting config becomes:

<IfModule mpm_worker_module>
    MaxClients           15
    MinSpareThreads       3
    MaxSpareThreads       7
    ThreadsPerChild       3
    MaxRequestsPerChild 200
</IfModule>

With this setup, I free up a significant amount of RAM from apache2's hold whle maximizing my thread usage in each worker process; at the same time, I avoid keeping each child process for too long by setting a maximum number of requests each worker can serve, preventing the workers to bloat too much when handling CGI.

I also tweaked the KeepAliveTimeout setting to just 2 seconds (instead of the default 15) so that each worker process can go to the next request quickly and preventing them from being tied up to a connection for too long. I also set the Timeout to 30 seconds.

Penso di essermi già lamentato abbastanza, in passato, di quanto il servizio .Mac sia arretrato rispetto alla concorrenza, o se non altro di come gli aggiornamenti ad esso siano scarsi e veramente rari. Una cosa che non ci si aspetterebbe, soprattutto visto il costo del pacchetto, di 99 euro l anno, che se non altro dovrebbe garantire una qualità pari a quella di simili servizi gratuiti di altre aziende. Nonostante questo io ne sono abbonato. Forse e soprattutto perchè oramai è da alcuni anni che lo utilizzo come email principale e, non avendo la minima voglia di cambiare l’indirizzo che oramai tutti conoscono come tale, continuo a rinnovare l’abbonamento.

Sembra tuttavia che vi siano novità in vista per il sito o che, meglio, vi saranno novità non appena uscirà l’iPhone 2.0, ovvero durante il WWDC. Questo poichè come si è visto da alcuni screenshot e rumors di giorni fa l’applicazione Mail dell’iPhone 2.0 dovrebbe consentire la ricezione Push delle mail, con gli account .Mac. Ma questa, a quanto sembra, non sarà l’unica novità introdotta: vi sarà infatti aggiunta la sincronizzazione On the Go, direttamente dal device al sito, della posta, dei contatti e dei calendari, e in più un software che la permetterà anche su Windows (dunque una specie di iSync per l’OS di Redmond).

Non male. Anche se si poteva sperare in qualche novità in più.
