"no hardware or software fault occurred *on the spacecraft*"

There may have been a hardware or software fault on the ground, that resulted in an invalid command sequence. The desired behaviour in this case may be to enter a safe mode, so that you have a known means to recover (rather than bricking).

"Systemd is causing massive bloat in Linux."

One of the main objectives of systemd is to take advantage of linux-specific features (such as cgroups) that existed before systemd did.

The servers I am building at present have a minimum of 256GB ram, I couldn't care about a few MB of "bloat", what I *do* care about is resource limits at various levels, which cgroups gives me and systemd makes useable but default.

if you were trolling, you're the worst systemd troll I've seen this year.

Did you actually bother reading up about IPv6 (like you probably had to to switch from IPX to TCP/IP)?

You can't just treat IPv6 as IPv4 with longer addresses, some concepts (such as broadcast address) simply don't exist in IPV4.

There are some very good free training materials available, such as from afrinic.

Depending on the features the ISP needs, there may not be a suitable upgrade yet.

For example half-duplex vrf isn't available on Cisco ASR9K (Cisco's IPV6 and RFC compliance first platform) and on Cisco ASR1K it doesn't support IPV4. As far as I know, ALU BNG also doesn't support IPV6 in HD VRF.

This is the reason for no native IPV6 over ADSL in South Africa

Except the 'security appliance' line does not run IOS. These are servers (originally re-badged Dell PowerEdge, but now Cisco UCS C-class rack-mounts) running AsyncOS (a proprietary FreeBSD-based platform), which used to be branded as Ironport.

It doesn't seem to affect any IOS flavour (IOS, IOS-XE which is Linux-based, IOS-XR) or the Nexus NX-OS (Linux-based).

Cost wise, a customer consuming 1TB via torrent is about the same as one consuming 100Gb via Netflix.

This may have been the case before Net neutrality.

Most high speed dedicated links are billed based on 95th percentile, which means the peak 1.5hours.

Before net neutrality, it was feasible to limit the peak, and have torrents consume the unused capacity off-peak. With net neutrality, this isn't as practical.

(I work for an ISP in a region that doesn't have 95th-percentile billing, we have to provision/pay capacity for peak demand, even if that is the 8 hours per quarter of iOS release day, or 2 hours per month of Patch Tuesday).

Comment: Re: Dependencies (Score 2) 119 119

Some init systems used on linux supported the LSB init script headers which do a similar thing. Some of them also supported parallel start-up (start all services whose dependencies are satisfied).

For example, Mandrake/Mandriva/Mageia used prcsys from around 2004 to 2013 (when Mageia switched to systemd).

But, there are a lot of advantages to systemd and most complaints about it are FUD that have been debunked.

Don't use Type=simple (the default) in a service unit if you don't want the 'simple process intended for use with inetd-style systems' behaviour. See the relevant man page (I think systemd.service) for other options that would be more appropriate for your use case (but I am not sure there is one for "anti-systemd FUD").

Comment: Net neutrality issue? (Score 1) 134 134

Is this really a net neutrality issue? Did anyone verify whether they are injecting across-the-board or only specific sites of competing services?

Disclaimer: I work for an ISP that does JS injection to notify users on quota-based accounts when they have used all of their data, the alternative is to hard redirect http and block all traffic until they log in to a portal.

"CEOs get their bonus by raising the stock price."

Even if everyone below them knows that in order to achieve the sudden increase they have destroyed the ability for the company to operate for more than another 5 years.

The usual approach by American MBA CEOs is to cut every conceivable operational expense that isn't required in the short term of their contract's huge bonus conditions (like stop maintaining equipment, getting rid of staff who work on future products or research etc.).

Comment: Re: vCenter Web Console vs vCenter desktop app exa (Score 1) 276 276

There is one thing the vSphere Web Client does exceedingly better than the (thick) vSphere Client: allows vSphere admins who don't use Windows on their laptops to work more effectively.

While there are some differences in functionality and where features reside, vSphere Web Client is fantastic (except that on Linux it only works on Chrome due to requiring a newer version of Flash than is available as a NPAPI plugin). The fact that the vCenter appliance supports bigger environments now actually allows one to run a non-Windows vSphere shop.

Red Hat's RHEV (vSphere competitor) only has a web app, and this has counted in its favour in the past when vSphere was limited to Windows only. We will be migrating to RHEV for other reasons though ...
