NAME
virtd_selinux - Security Enhanced Linux Policy for the virtd processesDESCRIPTION
BOOLEANS
SELinux policy is customizable based on least access required. virtd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run virtd with the tightest access possible.
If you want to allow virt to manage nfs file, you must turn on the virt_use_nfs boolean.
setsebool -P virt_use_nfs 1
If you want to allow virt to use serial/parallell communication port, you must turn on the virt_use_comm boolean.
setsebool -P virt_use_comm 1
If you want to allow virtual machine to interact with the xserve, you must turn on the virt_use_xserver boolean.
setsebool -P virt_use_xserver 1
If you want to allow virt to manage device configuration, (pci, you must turn on the virt_use_sysfs boolean.
setsebool -P virt_use_sysfs 1
If you want to allow confined virtual guests to interact with the sanloc, you must turn on the virt_use_sanlock boolean.
setsebool -P virt_use_sanlock 1
If you want to allow virt to use usb device, you must turn on the virt_use_usb boolean.
setsebool -P virt_use_usb 1
If you want to allow virt to read fuse file, you must turn on the virt_use_fusefs boolean.
setsebool -P virt_use_fusefs 1
If you want to allow virt to manage cifs file, you must turn on the virt_use_samba boolean.
setsebool -P virt_use_samba 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux virtd policy is very flexible allowing users to setup their virtd processes in as secure a method as possible.
The following file types are defined for virtd:
virt_cache_t
- Set files with the virt_cache_t type, if you want to store the files under the /var/cache directory.
- Paths:
-
/var/cache/oz(/.*)?, /var/cache/libvirt
virt_content_t
- Set files with the virt_content_t type, if you want to treat the files as virt content.
- Paths:
-
/var/lib/oz/isos(/.*)?, /var/lib/libvirt/boot(/.*)?, /var/lib/libvirt/isos(/.*)?
virt_etc_rw_t
- Set files with the virt_etc_rw_t type, if you want to treat the files as virt etc read/write content.
- Paths:
-
/etc/libvirt/.*/.*, /etc/xen/.*/.*, /etc/xen/[^/]*, /etc/libvirt/[^/]*
virt_etc_t
- Set files with the virt_etc_t type, if you want to store virt files in the /etc directories.
- Paths:
-
/etc/libvirt/[^/]*, /etc/libvirt, /etc/xen/[^/]*, /etc/xen
virt_home_t
- Set files with the virt_home_t type, if you want to store virt files in the users home directory.
virt_image_t
- Set files with the virt_image_t type, if you want to treat the files as virt image data.
- Paths:
-
/var/lib/imagefactory/images(/.*)?, /var/lib/libvirt/images(/.*)?
virt_log_t
- Set files with the virt_log_t type, if you want to treat the data as virt log data, usually stored under the /var/log directory.
virt_tmp_t
- Set files with the virt_tmp_t type, if you want to store virt temporary files in the /tmp directories.
virt_var_lib_t
- Set files with the virt_var_lib_t type, if you want to store the virt files under the /var/lib directory.
- Paths:
-
/var/lib/oz(/.*)?, /var/lib/libvirt(/.*)?
virt_var_run_t
- Set files with the virt_var_run_t type, if you want to store the virt files under the /run directory.
- Paths:
-
/var/vdsm(/.*)?, /var/run/libvirt(/.*)?
virtd_exec_t
- Set files with the virtd_exec_t type, if you want to transition an executable to the virtd_t domain.
- Paths:
-
/usr/bin/imgfac.py, /usr/bin/imagefactory, /usr/sbin/condor_vm-gahp, /usr/sbin/libvirtd, /usr/share/vdsm/vdsm
virtd_initrc_exec_t
- Set files with the virtd_initrc_exec_t type, if you want to transition an executable to the virtd_initrc_t domain.
virtd_keytab_t
- Set files with the virtd_keytab_t type, if you want to treat the files as kerberos keytab files.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux virtd policy is very flexible allowing users to setup their virtd processes in as secure a method as possible.
The following port types are defined for virtd:
- virt_migration_port_t
-
Default Defined Ports: tcp 8021
- virt_port_t
-
Default Defined Ports: tcp 8021
PROCESS TYPES
SELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux virtd policy is very flexible allowing users to setup their virtd processes in as secure a method as possible.
The following process types are defined for virtd:
virtd_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage port can also be used to manipulate the port definitions
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.

vignettes/stimulus-selection.Rmd
stimulus-selection.Rmd
This tutorial teaches you how to use the R
package
anticlust
for stimulus selection in psychological
experiments. All code can easily be reproduced via Copy & Paste. The
tutorial discusses the following functionalities:
To follow the code in this tutorial, load the anticlust
package first:
For the examples in this document, we use norming data for a stimulus
set provided by Schaper, Kuhlmann and Bayen (2019a, 2019b). It is
available when the package anticlust
is loaded:
data("schaper2019")
# look at the data
head(schaper2019)
#> item room rating_consistent rating_inconsistent syllables
#> 1 Feuchtigkeitsmaske bathroom 4.10 1.04 5
#> 2 Damenbinden bathroom 4.22 1.12 4
#> 3 Haarspray bathroom 4.32 1.13 2
#> 4 Tampon bathroom 4.35 1.22 2
#> 5 Badewanne bathroom 4.55 1.02 4
#> 6 Ohrenstaebchen bathroom 4.63 1.26 4
#> frequency list
#> 1 21 1
#> 2 19 1
#> 3 17 1
#> 4 17 1
#> 5 13 1
#> 6 21 1
The item pool consists of 96 German words, given in the column
item
. Each word represents an object that is either
typically found in a bathroom or in a kitchen. For their experiments,
Schaper et al. partitioned the pool into 3 word lists that should be as
similar as possible with regard to four numeric criteria (that is:
rating_consistent
, rating_inconsistent
,
syllables
, frequency
). Typically, stimulus
sets may contain more than 96 elements (and the selection usually
becomes more effective when the pool is larger), but the logic for
stimulus selection that is applied in this tutorial can be transfered to
arbitrarily large stimulus sets.
In the first example, I select two word lists that differ on
frequency but are as similar as possible with regard to consistency
ratings and the number of syllables. First, I need to define the
boundaries that define “high” and “low” frequency. Note that
frequency
is reverse-coded such that low values actually
indicate high frequency. Here, I arbitrarily define values below 18 as
“high” frequency and above 19 as “low” frequency, but any user-defined
splits are possible.
schaper2019 <- within(schaper2019, {
freq <- ifelse(frequency < 18, "high", NA)
freq <- ifelse(frequency > 19, "low", freq)
})
This code defined a new column freq
for the data set
schaper2019
that is either “low”, “high” or missing
(NA
). Let’s check it out:
schaper2019$freq
#> [1] "low" NA "high" "high" "high" "low" NA "high" "high" "low"
#> [11] NA "low" "high" "high" NA "high" "high" "high" "low" "low"
#> [21] "high" "low" "high" "high" "low" NA "low" "high" "low" "high"
#> [31] NA "high" "high" "high" NA NA "low" NA "low" "high"
#> [41] "low" NA "low" "high" "low" "high" NA NA NA NA
#> [51] NA "low" "low" "low" NA "high" "high" "low" "low" "low"
#> [61] "low" NA "high" "high" NA "low" NA "low" NA NA
#> [71] "low" NA NA "low" "low" NA NA "high" "high" NA
#> [81] "low" "low" NA "low" "high" "high" NA "high" "low" "high"
#> [91] NA NA "high" NA NA "high"
Before matching high and low frequency words, it is necessary to
remove cases that are not selected, i.e. where the entry in
freq
is NA
:
selected <- subset(schaper2019, !is.na(freq))
# see how many cases were selected:
table(selected$freq)
#>
#> high low
#> 33 31
Now, I use the anticlust
function
matching()
to find paired words of high and low frequency
that are as similar as possible on consistency and the number of
syllables:
# Match the conditions based on covariates
covariates <- scale(selected[, 3:5])
selected$matches <- matching(
covariates,
match_between = selected$freq,
match_within = selected$room,
match_extreme_first = FALSE
)
The first argument defines the covariates that should be similar in
both sets. I used the function scale()
before passing the
covariates to the matching function to standardize the variables. This
way, each variable has the same weight in the matching process, which is
usually desirable. The argument match_between
is the
grouping variable based on frequency
that I just defined.
The argument match_within
is used to ensure that matches
are selected between words belonging to the same room. The argument
match_extreme_first
is used to guide the behaviour of the
matching algorithm, but its precise meaning is not important for now
(for more information, see ?matching
). Generally, if we
plan to only keep a subset of all matches – as we do in the current
application –, we set match_extreme_first
to
FALSE
. If we want to keep all elements,
match_extreme_first = TRUE
is usually better.
Next, let us check out some of the matches we created:
subset(selected, matches == 1)
#> item room rating_consistent rating_inconsistent syllables
#> 12 Wattepad bathroom 4.39 1.14 3
#> 44 Rasierschaum bathroom 4.39 1.16 3
#> frequency list freq matches
#> 12 21 1 low 1
#> 44 17 2 high 1
subset(selected, matches == 2)
#> item room rating_consistent rating_inconsistent syllables
#> 29 Zuckerstreuer kitchen 4.48 1.04 4
#> 86 Mikrowelle kitchen 4.58 1.04 4
#> frequency list freq matches
#> 29 21 1 low 2
#> 86 15 3 high 2
The matches are numbered by similarity, meaning that matches with grouping number 1 are most similar. Therefore, we can easily select the 8 best-matched groups of words that we would like include in our experiment:
# Select the 8 best matches:
final_selection <- subset(selected, matches <= 8)
Last, we check the quality of the results by investigating the descriptive statistics – means and standard deviations (in brackets) – by condition:
# Check quality of the selection:
mean_sd_tab(
final_selection[, 3:6],
final_selection$freq
)
| rating_consistent | rating_inconsistent | syllables | frequency | |
|---|---|---|---|---|
| high | 4.39 (0.17) | 1.10 (0.05) | 3.50 (0.53) | 16.25 (0.71) |
| low | 4.38 (0.14) | 1.09 (0.03) | 3.50 (0.53) | 21.12 (0.64) |
The descriptive statistics are similar across the sets for the consistency ratings and the number of syllables, and dissimilar for frequency, which is good. In general, the results can even be improved if we can select from a larger item pool (then, more matches are possible).
If we are not sure how many items should be part of our experiment,
the function plot_similarity()
may help. It plots an index
of similarity (see ?plot_similarity
) for each match:
plot_similarity(
covariates,
groups = selected$matches
)
The figure depicts the sum of pairwise dissimilarities (based on the Euclidean distance) variance per match; the larger the value, the less homogenous the match. It seems indeed that the first eight matches are most similar; after the 8th match, there is already a notable decline in similarity.
# Reload the data for next example
data("schaper2019")
In another example, we construct a two-factorial design: we create
groups that differ on rating_consistent
and
rating_inconsistent
(these properties are orthogonally
crossed) but are similar on frequency and the number of syllables.
First, we categorize the variables frequency and syllables into two
levels, respectively. This time, I just use median splits, which means
that I do not exclude any data in this first step:
schaper2019 <- within(schaper2019, {
incon <- ifelse(rating_inconsistent < median(rating_inconsistent), "low incon", NA)
incon <- ifelse(rating_inconsistent >= median(rating_inconsistent), "high incon", incon)
con <- ifelse(rating_consistent <= median(rating_consistent), "low con", NA)
con <- ifelse(rating_consistent > median(rating_consistent), "high con", con)
})
Let us check how many words are left per condition:
table(schaper2019$con, schaper2019$incon)
#>
#> high incon low incon
#> high con 26 22
#> low con 27 21
Next, we conduct a matching between the four groups that resulted from crossing frequency and syllables:
# Match the conditions based on covariates
covariates <- scale(schaper2019[, c("frequency", "syllables")])
schaper2019$matches <- matching(
covariates,
match_between = schaper2019[, c("con", "incon")],
match_extreme_first = FALSE
)
In this application, each match consists of 4 words because we have 4 conditions, e.g.:
subset(schaper2019, matches == 1)
#> item room rating_consistent rating_inconsistent syllables
#> 7 Klobuerste bathroom 4.82 1.04 3
#> 47 Kloschuessel bathroom 4.84 1.13 3
#> 51 Sparschaeler kitchen 4.32 1.00 3
#> 57 Kastenform kitchen 4.10 1.18 3
#> frequency list con incon matches
#> 7 18 1 high con low incon 1
#> 47 18 2 high con high incon 1
#> 51 18 2 low con low incon 1
#> 57 17 2 low con high incon 1
To decide how many matched groups we would like to keep, let’s check out the similarity plot:
# Plot covariate similarity by match:
plot_similarity(covariates, schaper2019$matches)
Based on the plot, we select the 10 best matches:
# Select the 5 best matches:
final_selection <- subset(schaper2019, matches <= 10)
Last, we check quality of the selection by printing the descriptive statistics by condition:
mean_sd_tab(
subset(final_selection, select = 3:6),
paste(final_selection$con, final_selection$incon)
)
| rating_consistent | rating_inconsistent | syllables | frequency | |
|---|---|---|---|---|
| high con high incon | 4.68 (0.15) | 1.15 (0.06) | 3.40 (0.70) | 19.10 (1.85) |
| high con low incon | 4.70 (0.18) | 1.04 (0.03) | 3.40 (0.70) | 18.90 (1.45) |
| low con high incon | 4.32 (0.09) | 1.17 (0.04) | 3.40 (0.70) | 18.90 (1.66) |
| low con low incon | 4.26 (0.11) | 1.04 (0.03) | 3.40 (0.70) | 18.80 (1.55) |
Again, the covariates are quite similar between sets, but with a larger item pool even better results could be achieved.
# Reload the data for next example
data("schaper2019")
In the next example, we wish to partition the entire pool of 96 items into 3 sets that are as similar as possible on all variables. That means that there is no independent variable that varies between conditions; the experimental manipulation is independent of the intrinsic stimulus properties. Creating stimulus sets that are overall similar to each other can be done using anticlustering (Papenberg & Klau, 2020):
## Conduct anticlustering (assign all items to three similar groups)
schaper2019$anticluster <- anticlustering(
schaper2019[, 3:6],
K = 3,
objective = "variance"
)
## check out quality of the solution
mean_sd_tab(
subset(schaper2019, select = 3:6),
schaper2019$anticluster
)
| rating_consistent | rating_inconsistent | syllables | frequency | |
|---|---|---|---|---|
| 1 | 4.49 (0.25) | 1.10 (0.07) | 3.44 (0.98) | 18.31 (2.66) |
| 2 | 4.49 (0.23) | 1.10 (0.06) | 3.41 (0.91) | 18.31 (2.43) |
| 3 | 4.49 (0.27) | 1.10 (0.07) | 3.41 (0.91) | 18.31 (2.12) |
# Reload the data for next example
data("schaper2019")
If we do not want to include all 96 words in our experiment, we can
again use the matching()
function to select a subset of
similar stimuli that we employ. Again, we wish the select three groups
that are as similar as possible on all variables, but we only use a
subset of all 96 items. To achieve this goal, we create triplets of
similar stimuli using matching()
; afterwards, the items
belonging to the same triplet will be assigned to different experimental
sets. We use the argument match_within
to ensure that all
triplets consist of items belonging to the same room:
# First, identify triplets of similar word, within room
covariates <- scale(schaper2019[, 3:6])
schaper2019$triplet <- matching(
covariates,
p = 3,
match_within = schaper2019$room
)
# check out the two most similar triplets:
subset(schaper2019, triplet == 1)
#> item room rating_consistent rating_inconsistent syllables
#> 19 Kaffeebeutel kitchen 4.31 1.04 4
#> 58 Kaesemesser kitchen 4.28 1.04 4
#> 59 Cerankochfeld kitchen 4.34 1.04 4
#> frequency list triplet
#> 19 22 1 1
#> 58 21 2 1
#> 59 21 2 1
subset(schaper2019, triplet == 2)
#> item room rating_consistent rating_inconsistent syllables
#> 27 Buttermesser kitchen 4.40 1.00 4
#> 29 Zuckerstreuer kitchen 4.48 1.04 4
#> 53 Salatbesteck kitchen 4.48 1.02 4
#> frequency list triplet
#> 27 21 1 2
#> 29 21 1 2
#> 53 20 2 2
# Select the 10 best triplets
best <- subset(schaper2019, triplet <= 10)
Now, we use anticlustering()
to assign the matched words
to different sets:
best$anticluster <- anticlustering(
best[, 3:6],
K = 3,
categories = best$triplet,
objective = "variance"
)
In this function call, we pass the triplets
to the
argument categories
, thus ensuring that the matched items
are assigned to different sets. We can confirm this worked by looking at
the cross table of triplet
and
anticluster
:
table(best$triplet, best$anticluster)
#>
#> 1 2 3
#> 1 1 1 1
#> 2 1 1 1
#> 3 1 1 1
#> 4 1 1 1
#> 5 1 1 1
#> 6 1 1 1
#> 7 1 1 1
#> 8 1 1 1
#> 9 1 1 1
#> 10 1 1 1
Anticlustering strives to assign the matched triplets to the different sets in such a way that all sets are as similar as possible. Note that by ensuring that the triplets only consisted of items from the same room, the room was also balanced across anticlusters:
table(best$room, best$anticluster)
#>
#> 1 2 3
#> bathroom 5 5 5
#> kitchen 5 5 5
Last, we check out the descriptive statistics by anticluster, confirming that the sets are indeed quite similar on all numeric attributes:
## check out quality of the solution
mean_sd_tab(
subset(best, select = 3:6),
best$anticluster
)
| rating_consistent | rating_inconsistent | syllables | frequency | |
|---|---|---|---|---|
| 1 | 4.46 (0.26) | 1.08 (0.06) | 3.50 (1.18) | 19.00 (2.36) |
| 2 | 4.46 (0.22) | 1.08 (0.05) | 3.50 (0.97) | 18.90 (2.60) |
| 3 | 4.47 (0.28) | 1.07 (0.06) | 3.50 (0.97) | 19.00 (3.02) |

Do-it-Yourself cop car for $2K
New York Post | Submitted by: Phatlor
"Nobody turned away The Post's reporter and photographer when they sought
materials for a do-it-yourself cop car. The car's decals and lettering came
from a Manhattan graphics store. 'Can I ask you what you're going to do
with that stuff?' asked a store worker. 'I'm doing a photo shoot,' said
our photographer."  Hate to tell you
this Mr. Schumer, but there really is no way to stop anyone from doing something
like this without banning Home Depot entirely.

I'm just an interested non-pilot bystander, & hope it's OK to post here.
Thank you all for this truly fascinating information. I've a question arising from watching the ITVV DVDs: Having two pilots obviously gives some options if one becomes ill or incapacitated, but how were things handled if the FE became unable to perform his duties? Did the FO take over, & how familiar were the pilots with the FE's duties - could either pilot do the FE's job in full, or was it limited to some subset such as required for a diversion/landing etc. I assume this kind of thing was practised in the simulator regularly? I note (unless I've misunderstood) that there was some presetting of the load limit fuel transfer system, so that the pilots could initiate a CofG movement for descent if required. Thanks! |

I understand that before the first flights the test pilots had many sessions in the Concorde simulator. I have always wondered how before the first flight they decided to programme the flight enverlope into the simulator; especially as Concorde was so different to other jet transports?
I guess that as more information was gained during flight testing; that this was programmed into the simulator and therefore made it a more suitable machine for airline crew training. Thanks Nick |

For airline crew training , two new simulators were built in the early seventies, again one in Toulouse (later moved to CDG) and one in Filton. In the best Concorde style, they were designed and built by two different firms.... I don't believe anything of the development simulators has survived. As you will know, the "cab" of the British Airways Filton simulator was salvaged and taken to Brooklands, where it's now slowly being brought back to life. The Air France simulator at CDG, minus motion system and video display, was taken back to Toulouse, where it's slowly being restored, to go on display in the planned Museum at Toulouse. CJ |

M2dude,
The Braniff crews were great characters and yes many did wear cowboy boats, but the story I like is the one that goes as follows After hours of briefing prior to going on the simulator [for the first time] the Braniff crew got on the sim and went through all their checks, started the engines and taxied out to the end of the runway for their first Concorde sim take-off. Everybody was strapped in with seats in the correct position and all checks complete. The Captain called out "3,2,1, now" and all the throttles were moved sharply to full power and away we went with the visual showing the runway passing by at an ever increasing rate.  Needless to say that take off was stopped and we went back to start again at the end of the runway |

Many thanks for filling one of the many current gaps in my memory! I only "flew" her once, and that was on the original Filton development simulator. Took her up to Mach 2.11, well into the "cricket" zone... never forgot... (I think that was some development issue we were trying to settle at the time). I've been involved in a minor way with the restoration of both the Filton/Brooklands sim and the CDG/Toulouse sim, and with the SSTSIM and FlightSim Lab Concorde simulator programs, but never yet "flown" any of them. Maybe it's time I should ! CJ |

Concorde is a rare, and maybe unique, case.... Out of the eighteen surviving airframes... eighteen are now in museums. But all of them are now exactly that, museum exhibits, and none of them are even remotely likely to ever become airworthy again. And even some of the magnificient flight simulators that are around today (like the flight sim at Brooklands, or the current PC flight simulators, such as SSTSim or the new FlightLabs one) do not allow anyone to become "current" again on Concorde.

FSLabs - Concorde-X simulation for FSX
Update: This reply was not intended to be posted publicly, as it was directed to select few individuals. We will, however, honor all requests sent to Flight Sim Labs, Ltd. until 30 September, 2010. Apologies for the inconvenience!
--- Gents (and Landlady!), I am ashamed to admit that I only now discovered this wonderful thread regarding the best aircraft that ever was. I've chatted with some of the great minds behind the development of the actual aircraft and I've felt very proud that a select few (ChristiaanJ and others) have helped my team with invaluable insight as we developed the Concorde-X addon product for Flight Simulator X. (We only hope we did "her/him" a bit of justice with our final result). In recognition of all your efforts, I'd like to offer everyone who has been involved in the development and/or flying of the real aircraft a free download copy of our product, if only as a token gift which might bring back some memories of what it felt to be inside its Flight Deck and cabin. Just write our support team (support (at) flightsimlabs (dot) com) a small note (please give us some info on the nature of your relationship with the bird) and we'll provide you with the information required for the download. Please keep those memories coming - they are the best way to keep the legacy going! Regards, Lefteris Kalamaras Flight Sim Labs, Ltd. |

Are there any concorde simulators that are still working and retain their certification?
Regarding LHR JFK routes. What was the avarage fuel load and how close to full tanks was it. At FL500-600 what sort of wind was usually encountered. So high above the tropopause I would think very little. Flying magazine from the US did a spread on the concorde many years ago. Theye stated that the wind component was such a little percentage of TAS that the block times rarely differed by more then 10 mins. True or false. They also said that the type rating course was so hard that only the top performers (pilots) were selected for the training and even then there was a 50% washout rate. True or false. Does anyone still have a complete set of ground school notes? |

For various reasons, only the simulator 'cab' could be salvaged. It was taken to Brooklands to be used as a static exhibit of what the Concorde cockpit looked like. It was only well after its arrival at Brooklands that people started to think about bringing it back to life.... a huge piece of work, since about all that was left was the 'cab' itself, with the instruments and controls... the computers and interface circuits, needed to make them work, were all gone. A team of volunteers, a simulator firm and university students have now brought it back to a state where it can be 'flown'. Even if not everything works yet, ex-Concorde pilots who've 'flown' it were already full of praise. As to the visuals, the original visual system was taken back by BA, since it was recent and the same as used on other BA simulators. It's been replaced by a specialised video projector and a wide screen, which appears quite satisfactory, although I 've heard rumours about plans to replace it with a three-projector system. The story of the Air France simulator, that was located at CDG, is very different. After the end-of-service it was moved almost in its entirety to Toulouse (Airbus), minus only the visual display system and the motion platform. A small team of volunteers (mostly Airbus engineers) are slowly bringing that one 'back to life' as well, but (contrary to Brooklands) using most of the original electronics. The intention is to have it ready for display (and use) at the Toulouse 'A\xe9roscopia' museum, which hopefully will open within a few years. Unfortunately, until then the sim is not accessible to the public, since it's inside one of the Airbus site buildings. And no, of course that one isn't certified either.... One small bit of trivia... the BA and AF simulators were NOT built by the same firm. The BA one was built by, IIRC, Singer-Redifon, and the French one by LMT. Today that's a pity, really, because the Brooklands and Toulouse teams have very little technical information they can exchange. Oh and, yes, I've visited and sat in both of them, but so far I haven't flown either of them yet. CJ |

The AF simulator was regarded as a sub standard machine, never had the required interface or processing power compared the the UK machine that was built as a joint effort by Sinker-Link Miles (structure and motion) and Redifon simulation (interface and computers), with a view that the developed product would be offered to the option holding airlines.
A key failing of the AF machine was that it could not correctly simulate an engine failure on take off without going off the runway. So what happened when AF had an apparent engine failure/fire after V1 in 2000? The crew made a right hash of the procedures....Nuff said really. |

The last time that I 'flew' the Concorde simulator at Filton was about 15 years ago. The visuals were the superb Rediffusion (as it was called then) 'Wide' displays and I seem to remember that there was a sort of mechanical mask over the screens that looked somewhat like the visor, and this came up and down with the visor control lever. The very first time that I went on the sim' was in 1980, when the visuals comprised of a TV screen at the central parts of the windsheilds. (The DV and side windows I seem to remember were blanked out). The 'picture' was provided by a TV camera tracking over a huge vertical landscape model, populated with runways, houses, cows, fields etc. (If one of the models became 'unglued' it would appear to shoot horizontally across the screen).
I think that these Rediffusion 'Wide' vusuals were installed in the late 80's/early 90's and were as advanced as any simulator visuals anywhere. I believe that the original 'landscape model' was donated to a university. Dude |

Dude - that really brings back pain form the past! I remember knowing (just) enough about the flying controls to pass the ARB, but a diagram similar to that one was presented at one "Technical Refresher" day (remember those?) by one of our more chatty training EOs (could have been you?!) together with a coloured plastic overhead projector schematic complete with slidey moving jacks and PFCUs and things and it worked! I completely understood the system right up until the first pint of Brains that night...
Flying in mechanical signalling was a different experience - losing the autostabs was bad enough (and proved how good that system was). A mate on the fleet once described it as like trying to fly around on a supersonic dustbin lid. I think that description was too kind - the thing was barely controllable in that configuration. One of our skippers described an airtest when he was on the JS where the crew were trying a decel in MS: as the phugoids were diverging he thought he was about to lose his life so leant forward to restore things. Sadly the switches had been left in MS, so he had to move the switches up to "Blue" as well as then pressing the reset tits - a procedure which he described as almost impossible due to the ever more extreme manoeuvres. Recovery, fotunately, was instant. Resetting electrical signalling and autostabilisation always felt like slotting into a groove on the Concorde. For that reason, I believe, flight in mechanical signalling was removed from transonic flight on airtests and altogether from Base Training. The simulator was the only sensible way of trying to fly like that... And that flying control pre-flight check! Learning it was a conversion course rite of passage: one of the sadder parts of reading this thread was realising I'd forgotten it. Great times, great aircraft, great people. Nostalgia isn't necessarily a thing of the past... see you in March? |

Yes there was an Ignitor selector labelled LH--Both--RH, however the engines would be started using only one ignitor. This caused a few small but annoying delays as if the selected ignitor failed the start would have to be stopped the starter given a cooling period and then a further engine start using the other ignitor would be attempted, however it did give a running check that both ignitors were working. This was not very popular with the crews and the ground engineers were persuaded to test the ignitors before presenting the aircraft for service. However due to the engine starting Fuel Pump switching, this resulted with a small fire in the hanger, and so the crews were back to starting on Lh or RH ignitors. If I remember correctly the RR Conways on the VC-10 also had 2 ignitors per engine with a LH--Both-RH selector.

If you remember, if something went wrong with the Flying control check the F/E was always busy. This gave him a chance to think up a suitable answer or even better the pilots did the check again and it now worked.

Hello All,
I would like to buy/build an energy monitor for my PV/home grid system.
Is the wireless transmission the only way to connect the modules? Grid/PV meters are remote and wireless won't make it, besides I prefer wires communication and is not a problem to run them.
Many thanks
Attila
Re: Wired Energy monitor
I think it's been done, but I'm not sure of the distances involved. From memory it was the I2C that was used - MartinR certainly used the I2C bus to communicate between stacked emonTx V2s in his "Full fat" 3-phase monitor, so if the bus will drive the distance you require, that should be at least one possible solution.
Re: Wired Energy monitor
Sure, about any transport method you choose is possible. Assuming you're using the emonTX V3 code, the data transmission is handled by send_rf_data(). Using a different transport method is just a matter of using different code in that function, and having the supporting libraries for the new interface of course. Whether there's existing software for OEM that'll use the interface you want is another question. If you're willing to put in a bit of work though, it's probably not a large effort.
If Ethernet is of interest, that should be doable, and will take you a further distance than i2c without having to potentially deal with various signaling issues. If you decide to use an arduino ethernet board/sheild and the RFM is still populated but unused, be aware that a complication exists depending on which hardware revision you have for the ethernet board/shield. The SS pin on the Wiznet chip isn't wired correctly on certain arduino ethernet boards/shields. That bug is resolved in current hardware, and there are workarounds published for older hardware, but if you're not using the RFM, may as well not populate it, if possible.

Generating binding definitions and XML schema definitions from Java code is easy with JiBX. The BindGen tool, added in the 1.2 release, allows you to use both automatic and customized conversions for your Java classes. It provides a much better feature set than any of the alternative ways to generate schema definitions from Java code, including:
For an in-depth look at using BindGen, see the JiBX 1.2, Part 1: Java code to XML schema tutorial on the IBM developerWorks site. You can also look over the BindGen examples included in the distribution, which are discussed in this section of the documentation.
Besides generating schema definitions, you can also generate WSDL definitions from Java code. This uses the Jibx2Wsdl tool. Jibx2Wsdl builds on BindGen's features for generating data structure schemas, while adding equally-attractive features for generating WSDL service descriptions.
This section of the documentation covers both BindGen and Jibx2Wsdl. It also includes information on the associated SchemaGen tool, which is primarily intended for use by BindGen and Jibx2Wsdl but can also be used directly.

This example is designed to allow you to experiment with the various configuration properties provided by AutoComplete and to explore their impact on the interaction. The first field after the AutoComplete input textbox is a select element that allows you to test for bleed-through on Internet Explorer when the AutoComplete suggestion container descends to cover it. The remaining form fields allow you to change property settings on the AutoComplete instance and to see immediately how those changes look and feel in the browser.

The f_mkfs fucntion creates a file system on the drive.
FRESULT f_mkfs ( BYTE Drive, /* Logical drive number */ BYTE PartitioningRule, /* Partitioning rule */ UINT AllocSize /* Size of the allocation unit */ );
The f_mkfs function creates an FAT volume on the drive. There are two partitioning rules, FDISK and SFD, for removable media. The FDISK format is recommended for the most case. This function currently does not support multiple partition, so that existing partitions on the physical dirve will be deleted and re-created a new partition occupies entire disk space.
The FAT sub-type, FAT12/FAT16/FAT32, is determined by number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. The cluster size affects performance of the file system and large cluster increases the performance.
Available when _FS_READOLNY == 0 and _USE_MKFS == 1.

Trump to visit Apple’s Mac Pro plant in Texas tomorrow
Washington: In order to send a message to companies in the US to bring back manufacturing home and create more jobs, US President Donald Trump will visit Apple’s Mac Pro plant in Texas on Wednesday, The White House has confirmed. As part of its commitment to US economic growth, Apple in September confirmed that its newly redesigned Mac Pro will be manufactured in Austin, Texas. The latest generation Mac Pro will be produced at the same facility where Mac Pro has been made since 2013.
According to a CNBC report on Sunday, the White House confirmed the visit is scheduled to take place on Wednesday. It is likely that Apple CEO Cook would accompany Trump at the plant. Apple has asked for more exemptions on tariffs on Chinese-made Apple Watches, iPods, iPhone components and other consumer products from the US government. The new tariffs took effect in September as part of the US-China trade war.
The new Mac Pro will include components designed, developed and manufactured by more than a dozen American companies for distribution to US customers. (IANS)

ViewBag, ViewData & TempData
The "Music Store" web application does use only the "ViewBag" so we will write some tests for it. The "ViewData" and the "TempData" use similar syntax.
Testing with ViewBag entry
Let's test something simple - the HTTP Get overload of the "Login" action in the "AccountController":
public IActionResult Login(string returnUrl = null)
{
ViewBag.ReturnUrl = returnUrl;
return View();
}
We need a new dependency (seriously, stop it with these dependencies) - "MyTested.AspNetCore.Mvc.ViewData":

<PackageReference Include="xunit" Version="2.4.0" />
<PackageReference Include="xunit.runner.visualstudio" Version="2.4.0" />
</ItemGroup>
<!-- Other ItemGroups -->
We need to add the "ViewData" features, because the "ViewBag" is actually a dynamic version of it.
I hope you remember how we tested session and cache. Well, the "ViewBag" ("ViewData" and "TempData" too) is no different:
[Theory]
[InlineData("Test/Return/Url")]
public void LoginShouldHaveReturnUrlInTheViewBag(string returnUrl)
=> MyController<AccountController>
.Instance()
.Calling(c => c.Login(returnUrl))
.ShouldHave()
.ViewBag(viewBag => viewBag // <---
.ContainingEntry("ReturnUrl", returnUrl))
.AndAlso()
.ShouldReturn()
.View();
Testing with multiple ViewBag entries
Let's write another one - for the HTTP Get overload of the "Create" action in "StoreManagerController":
public IActionResult Create()
{
ViewBag.GenreId = new SelectList(DbContext.Genres, "GenreId", "Name");
ViewBag.ArtistId = new SelectList(DbContext.Artists, "ArtistId", "Name");
return View();
}
And our test:
[Fact]
public void CreateShouldHaveValidEntriesInViewBag()
{
var genres = new[]
{
new Genre { GenreId = 1, Name = "Rock" },
new Genre { GenreId = 2, Name = "Rap" }
};
var artists = new[]
{
new Artist { ArtistId = 1, Name = "Tupac" },
new Artist { ArtistId = 2, Name = "Biggie" }
};
MyController<StoreManagerController>
.Instance()
.WithData(genres)
.WithData(artists)
.Calling(c => c.Create())
.ShouldHave()
.ViewBag(viewBag => viewBag // <---
.ContainingEntries(new
{
GenreId = new SelectList(
From.Services<MusicStoreContext>().Genres, "GenreId", "Name"),
ArtistId = new SelectList(
From.Services<MusicStoreContext>().Artists, "ArtistId", "Name")
}))
.AndAlso()
.ShouldReturn()
.View();
}
The "ContainingEntries" call is equivalent to this one:
.ContainingEntries(new Dictionary<string, object>
{
["GenreId"] = new SelectList(
From.Services<MusicStoreContext>().Genres, "GenreId", "Name"),
["ArtistId"] = new SelectList(
From.Services<MusicStoreContext>().Artists, "ArtistId", "Name")
}))
Both methods will validate whether the total number of entries in the "ViewBag" is equal to the total number you provide in the test. For a sanity check - remove the "ArtistId" property from the anonymous object and run the test again:
When calling Create action in StoreManagerController expected view bag to have 1 entry, but in fact found 2.
If you do not want the total number of entries validation, just use:
.ViewBag(viewBag => viewBag // <---
.ContainingEntry("GenreId", new SelectList(
From.Services<MusicStoreContext>().Genres, "GenreId", "Name"))
.ContainingEntry("ArtistId", new SelectList(
From.Services<MusicStoreContext>().Artists, "ArtistId", "Name")))
ViewData and TempData
"ViewData" has the same API:
MyController<SomeController>
.Instance()
.Calling(c => c.SomeAction())
.ShouldHave()
.ViewData(viewData => viewData // <---
.ContainingEntry("SomeKey", someValue))
.AndAlso()
.ShouldReturn()
.View();
"TempData" too, but you will need the "MyTested.AspNetCore.Mvc.TempData" package:
MyController<SomeController>
.Instance()
.Calling(c => c.SomeAction())
.ShouldHave()
.TempData(tempData => tempData // <---
.ContainingEntry("SomeKey", someValue))
.AndAlso()
.ShouldReturn()
.View();
Additionally, you can populate the "TempData" dictionary before the actual action call:
MyController<SomeController>
.Instance()
.WithTempData(tempData => tempData
.WithEntry("SomeKey", someValue))
.Calling(c => c.SomeAction())
.ShouldReturn()
.View();
Section summary
We saw how easy it is to test with "ViewBag", "ViewData" and "TempData". Their fluent assertion APIs are very similar to the "Session" and the "Cache" ones. But enough about controllers, let's finally move on to View Components!

Barack's first-place match had excellent back and forth. In the start, he had instinctively good timing for finding points. His opponent was forced to look for points aggressively. Overall, Barack had much better control and movement, but his opponent started to come back in the end. Luckily, Barack was able to power through and win!
