Spot the gap!

ESA publishes some really good high resolution photographs of the STM (Structural and Thermal Model) and in some of them it is possible to see there is a platform that the tubular sunscreen connects to, then a gap, then below it the instruments (this organisation can be seen in some sketch/CAD diagrams of the instruments found elsewhere).

The gap between instruments and platform appears to be covered with flaps of gold foil which in some photographs are unclipped and others partially clipped. It looks likely that when the telescope is oriented such that the solar panels aren't aimed perpendicular to the sun, light can pass the edge of panels and is supposed to be reflected away by the tube and these foil flaps. It is possible that one or more foil flaps isn't correctly overlapping - that would explain why light pollution only occurs at specific angles to the sun.

See this and its list of "Related" images:

Snaps and the fin' FOSS....

... stands for Freedom.

No matter how much freedom of choice you give, someone will always want more. Don't give them that freedom and they'll happily just get on with what they're given (e.g: Apple, Microsoft).

Tinkering with the desktop stuff always strikes me as rearranging the deck-chairs on the Titanic whilst it's sinking :)

Snap is there to allow software publishers to push out frequent changes to their software including more recent library dependencies than are in the 6-monthly Ubuntu releases, and to avoid having to learn Debian style packaging or deal with the discipline of getting their project accepted into Debian (Ubuntu's upstream) so that it flows into Ubuntu.

Some of the issues with snaps and specifically Ubuntu:

0. Critical vulnerabilities in core libraries are fixed once in the apt world and managed by a distro-wide team of maintainers. In Ubuntu there is a dedicated paid security team; in the snap world if multiple snaps embed their own versions of the affected library firstly you may not know, secondly you're reliant on swift and correct fixes and publishing of updates, and thirdly the 'team' responsible for doing those things may only be a single person publishing in their free time.

1. Core packages moving from apt repository to snap, making life difficult if one choses to remove snapd (affects -server (e.g. lxd) as well as -desktop (e.g. gnome))

2. Delivery system (snap store) is closed source. Unable to set up alternatives, or local 'stores', as is possible with apt repositories

3. Canonical controls the delivery mechanism and acts as gatekeeper

3. Mixing of open and closed source packages in the same repository (no pockets so one can easily avoid closed-source for example)

4. Lots of manual work required to obtain source code of open-source packages (see https://merlijn.sebrechts.be/blog/2020-08-17-verify-snap/ ) in contrast to: "apt-get source $package"

5. No easy way to replicate the build environment of a snap and do reproducible builds, in contrast to "apt-get build-dep $package; apt-get source $package; cd $package-$version; fakeroot debian/rules binary"

6. Reporting of bugs is not centralised via bugs.launchpad.net as it is with all Ubuntu apt packages (which also includes all package version build histories, build logs, changelogs, and source repositories)

7. Variable or lack of (professional) support. Ubuntu Advantage / Pro paid support packages do not cover snaps in the same way as they cover the apt repositories. Pro covers 2,300 packages in the Ubuntu Main repo, plus an additional 23,000+ packages in the Ubuntu Universe repository for 10 years. ( https://ubuntu.com/pro )

Autonomy's Mike Lynch loses battle against extradition to the US on fraud charges

Caveat Emptor (Buyer Beware) ?

The whole episode doesn't look good for either side. Some facts that often don't get stated make the current status more understandable.

Although originally a UK company (Autonomy Corporation PLC) it listed its shared on the US NASDAQ exchange so financial oversight was a US concern as well.

Evidence from the various trials and audit reports appears to show that HP C-level and directors curtailed or ignored due diligence reports and advice from their own financial people regarding value

HP offered a 79% premium on the share price when it made its offer in August 2011 (share price ~ US$23.50, offer US$42.11)

In October 2011 HP bought 87.3% of the shares (~242,222,749) for US$10.2 billion (giving the balance sheet valuation of ~US$11.7 billion)

If HP hadn't offered and paid the premium then the value of the company at time of offer was ~US$6.5 billion

HP C-level and directors must have decided that paying 79% premium was worth it based on projected revenues.

Evidence seems to show that methods, information and supporting data for recognising sales, and projected revenues ,was manipulated within Autonomy senior leadership.

Auditors for Autonomy signed off on the accounts that incorporated the disputed methods and information.

How it works!

"Data protection is achieved by using a bit-cover process before frames are grouped into information blocks for encoding. The DVB-S2 short block code [4] is used as the primary forward-error-correction (FEC) mechanism. This provides a fixed 16,200 bit encoded block length based on a combination of LDPC and BCH techniques with resulting rates ranging from 0.19 to 0.88 and supporting approximately 10 dB of link SNR fluctuation for a given symbol rate and modulation.

Codeword data is grouped into symbols and multiplexed across many hops, where a hop is the duration of time a transmission stays at one frequency before “hopping” away to another frequency. The hops are then permuted in time. Together, these features provide increased resistance to transient jamming or interference."

Upgrading what might be the world's oldest running Linux install

TJ1

Re: LVM over RAID over LVM

If this OS install has grown over time with in-place incremental upgrades it makes a lot of sense. Logical Volume Management (LVM) has gained features over the years that probably were not available when LVM was first adopted.

Physical > LVM > RAID >LVM is probably due to LVM not supporting RAID modes originally so likely it is Multiple Device (MD) RAID - probably RAID-1 mirror.

My guess would be originally the install was on a single HDD. As more storage is required it is far easier to manage it flexibly via OS (e.g. LVM) services rather than hardware RAID. So, add in more physical HDD/SSD, "pvcreate ; vgextend" and then "lvextend" for those volumes needing more space.

So over time, without any major OS re-installation, using several physical HDD/SSDs, the host has a RAID mirror with OS and data volumes on top.

Nowadays LVM supports RAID modes natively (using the kernel Device Mapper (DM) MD RAID functionality under the hood) so the additional layer could be removed whilst the OS is operating without too much trouble (I've done this on multiple systems over the years). This is one of the delights of using LVM - being able to re-shape storage architecture quite fundamentally whilst the system is live (including more exotic options like adding iSCSI block devices as LVM PVs to create remote mirrors).

I've also done a similar live migration from 32-bit to 64-bit in-place (original 2007 install, host still in operation). Once the kernel is switched to 64-bit it supports both 32-bit and 64-bit user-space. At that point you can create a 64-bit chroot install with all the required packages followed by copying over configuration files package by package and switching the running service from the 32-bit to 64-bit in the chroot.

Eventually you've a 64-bit kernel with a base 32-bit core running all 64-bit services. At that point the boot configuration can be pointed at the 64-bit root file-system (a Logical Volume) and the system rebooted.

When doing this it helps to actually upgrade the 32-bit packages to the target OS version first so that the package upgrade scripts handle most of the per-package configuration file changes for you. If skipping several OS releases it's unlikely we could rely on that to correctly handle all changes and would have to manually check and review each package configuration. Once that's done the switch from 32-bit to 64-bit should be straight-forward.

JavaScript dev deliberately screws up own popular npm packages to make a point of some sort

TJ1

Re: Quantity of Downloads vs Requires

Agreed about the numbers - but my primary point is the sheer complexity of verifying the combined effect of the sheer number of dependencies in most large applications, especially where there is a frequent commit cadence across the application and its dependencies.

Also, in respect to CI/CD those won't be doing a rebuild and test cycle on each commit or PR on all those dependencies - or randomising the test harness to reflect real-world client connections.

I can easily imagine one of the many dependencies introducing subtle, conditional, behavioural changes that don't do anything different when in a test environment but could trigger malicious payloads on very specific request parameters (IP address, referrer, user-agent, date/time, request parameters, etc.).

TJ1
Go

Widen the horizon - also affects live web, GoLang, Perl, Rust, etc.

I fully agree with sentiments regarding the typical Javascript eco-systems with regard to pulling in miscellaneous dependencies without review although I feel the language itself (sans strong typing) is as good or bad as any other, depending on the project requirements.

I get most upset by 'live' dependencies in web-sites to third party served code - the code being served can be trivially modified by the server based on the requesting user agent identity, IP address, and other heuristics, to deliver a highly targeted malicious payload that the web-site/application developers could never trigger.

For $deity's sake copy and serve the verified code/resource to your own server on the same domain as the primary resource!

However, a similar dependency eco-system exists with Rust crates and GoLang imports.

I was quite interested in certain GoLang projects until I dug deeper and two things stood out in particular to me and my requirements:

1. On Linux, code making syscalls needed (at the time I reviewed it - may have changed) to run a C-language co-process to call into the kernel. This aspect introduced some 'interesting' complexities and rather spoiled some of the GoLang promise (and performance - learned via 'crun' - the C-language alternative to 'runc').

2. In typical projects the source-code has an alarming number of "import "github/user/project" which relate to external dependencies fetched using "go get ..." so these external dependencies (and the graph of dependencies in a typical application-level project) have a similar security/review cycle issue.

Similar issue for point 2 in Rust Crates. Each Cargo.toml may well include lines of the form "some_external_library = { git = "https://github.com/SomeRandomAccount/SomeExternalLibrary" }"

Same applies to Perl with CPAN and others.

It seems to me there's a seesaw sliding-scale between Convenience and Trust and currently the scale is tipped too far in favour of Convenience.

Trust comes from reviewing the code - either yourself or your team, or by people you trust (typical web of trust). For example in Linux distributions we typically favour the package maintainers with implicit Trust when installed dependencies.

The problem, and challenge, for 'import the latest from $pseudo_random source' is the lack of a web of trust for each version/release/commit.

Quantity of Downloads vs Requires

Slight tangent, but related to a point that BinkyTheMagicPaperclip brings up previously: "Never, ever, blindly pull the latest version into your product without thorough testing"

"colors.js is incorporated into almost 19,000 other npm packages and gets 23 million downloads a week."

This scares/worries the systems engineer in me.

If on a WEEKLY basis 23,000,000 downloads (requires/imports) are being done across ~19,000 dependencies, and if a similar relationship holds for other critical dependencies, that seems to suggest a huge number of projects frequently iterating builds and deployments.

Bearing in mind this is a single package the security vulnerabilities of this practice seems stark across the Node.js ecosystem.

Underlying Technical Details

It's important to understand that ARNS (Aeronautical Radio-Navigation Service) operates in the 4200 - 4400 MHz range for transmit and receive. The issue appears to be a combination of ARNS receivers being sensitive to (strong) signals outside the immediate band and the cellular base-station signal strength in 3700 - 4000 MHz.

Historically the band has been used for low-power services that do not suffer 'bleed' so ARNS receiver design especially didn't require tight band-pass filtering.

"It should be understood then that any interference that is unpredictable and that can mix with the linear FM waveform, thereby causing the radio altimeter to mistake the mixed signal as terrain has the potential to cause a radio altimeter to report a false altitude. "

Re: What was the ping fix?

This transcript of the trial [0] seems to show the Ping Fix was a correction to the Horizon system involving reconciling of Camelot/Lottery transactions which originally were not handled by Horizon - the Ping Fix is apparently the addition of functionality to Horizon that relies on data provided by Camelot but still didn't get it right:

"PG so lottery and paystation weren’t part of the original Horizon design and that introduced the pre-PING issue of mistakes between terminals and post-PING it introduced the issue of dodgy TAs and integrity of the datastream?

AB yes"

From that transcript it seems like originally the Camelot/Lottery transactions were reconciled almost manually at PO HQ and in doing so introduced lots of errors, and after the Ping Fix were/should have had Transaction Corrections (TCs) but those often did not receive Transaction Acknowledgements (TAs) or TCs and TAs were applied in error - the meaning of the acronyms is not spelt out there so I may have those wrong..

Sounds to me like the whole mess was due to transactions from branch A being mixed up with some other branch due to the poor system integration and reconciliation of transactions.

Re: 3 seconds boot time?

Many times slow boot (or more accurately, time to reach "graphical.target") is due to waiting for the "network-online.target" which will only be reached on most laptops once the/a WiFi network is found and connected.

This is usually a side effect of configuring a Network Manager (WiFi) connection to be available to all system users which causes it to be brought up before desktop log-in is reached.

However, for the more general case systemd provides useful tools for identifying where boot-time delays occurred:

systemd-analyze critical-chain

systemd-analyze blame

By default these assume "--system" but with "--user" the user session start-up can be analysed separately.

"critical-chain" is the most useful when one service is delaying others, such as when waiting for a network connection to become available. The numbers show the @when and the +duration of each unit. E.g: on my laptop it takes +5.649s for the WiFi connection to be established:

graphical.target @11.614s

└─multi-user.target @11.614s

└─kerneloops.service @11.579s +34ms

└─network-online.target @11.570s

└─NetworkManager-wait-online.service @5.919s +5.649s

└─NetworkManager.service @5.419s +403ms

└─dbus.service @5.158s

└─basic.target @5.091s

TJ1
Thumb Up

BT dig up copper before thieves do!

Reports suggest spending £30 billion - that is the ball-park of what most experts believe the cost of delivering Fibre To The Premises nationwide would likely be.

According to reports in 2014 when the Government was first consulting on switching off the analogue network, and later in 2018 when BT/Opereach began consulting about withdrawing the Wholesale Line Rental (PSTN) products in favour of VoIP [2]:

"Most of the telephone network is owned by BT, some 75 million miles of wire, worth between £2.5bn and £5bn according to a 2011 estimate by Investec bank"

There was disagreement by BT at the time over the original Investec estimate that the copper could be worth £50 billion so it isn't clear what the current value is but it looks like, if it can be extracted cheaply, it could fund part of the switch to a full fibre diet, err, network!

Let's not knock the target - if it transpires BT/Openreach does want to rapidly convert to a full-fibre network (finally) including rural areas - cheer them on, even if the reality is it cannot be delivered to an unrealistic timetable; once the ball is rolling it is going to gain momentum.

As someone on the end of 2km of (quality) copper with VDSL hovering around 10Mbs/0.9Mbps I for one welcome the fibre overlords!

According to the indictment:

"j. On or about November 18, 2015, defendant YAO travelled from China to O'Hare International Airport in Chicago, Illinois. At the time, he had in his possession over 3,000 unique electronic files containing Company A's proprietary and trade secret information, including nine complete copies of Company A's control system source code and the systems specifications that explained how the control system source code worked."

Unless Yao was arrested at O'Hare how is this known unless Yao's devices were cloned and the images later inspected ?

Or is this sleight-of-hand wording to imply Yao was carrying those documents through the airport? Note the indictment uses the term "in his possession" which isn't the same as "carrying" - potentially all this means is Yao is alleged to still have copies of those trade-secret documents after ceasing to be employed by Company A. It could be this wording is being used to satisfy the 'inter-state' requirement for bringing charges.

Profit Margins

I agree with others that this data should be published, but in terms of guessing what Amazon's reasoning is, I'd suspect it might have to do with revealing to its competitors what their energy cost is and therefore, indirectly, what their margins are. Energy is probably the largest ongoing operational expense for a data centre so small differences in efficiencies probably represent several % points of profit margin.
