How to build beautiful sites that work everywhere
This week we had to learn everything about making responsive websites starting for our blog. It was interesting to really think about this topic that I'm used to just take for granted. A website should just work in your phone right? Well, it's not that easy of course...
Not so long ago, the norm was to design for the desktop version of the webpage and then either adapt this design to work on phones or create a completely different version of the page called mobile version, or furthermore, a mobile application. This meant a lot more maintenance and extra work that needed to be done in order to keep the content updated on both versions as well as the fact they will probably have different features all together, not to mention a separated set of code and platforms on the apps. But technology is constantly evolving and in the past few years we have seen a rise in the use of all kinds of devices such as tablets, smartphones, smart-tvs, etc. that consequently have all sorts of different screen sizes and controls.
The design for desktop was not longer working as well and it was time to devise a new strategy to make websites that will work and look good on all -or most- devices. This is where responsive design comes along. The concept of responsive design means to create a single website to suit all needs, not mobile versions or apps. In order to do this developers use tools in CSS that allow the page contents to change depending on the screen size.
I think Responsive Design is only going to get more and more important over time as people tend to use their mobile devices more over desktop computers. I personally interact way more with websites through my phone than my desktop PC. I use the computer only to watch movies and play videogames, besides of work of course. I pretty much do everything else on my phone including my banking, emails, shopping, recharging the bus card, and more.
The next big concept we learned was Frameworks, and a really cool one it is. Frameworks are a set of predefined styles that allows the developers to do certain things easier and faster. They vary from more simple to really complex ones that have many features. To put it in simple words: somebody found solutions to make things work in a certain way and they share it with others so they don't have to create it again from zero (no need to re-invent the wheel).
Then we have this other cool thing called Wireframes, which are sort of schemes or simple drawings of what you will want your website to look like before starting the design process. Wireframes allow you to have some idea of the position of the different elements of the page without adding any style elements yet. Here you can see some examples of the wireframes I made for this personal website.
I made many mistakes when trying to implement these, he he. The most noticeable one was that I completely missed the "Home" button when doing the mobile version ('doh!'). Then I had this great idea of making a collapsible navigation bar which I might not be able to implement until I know anything about Javascript.
"Work in progress" should be the title of the site now, but one day, one day!...

<begin log>
201█-07-11 7:21 AM The neighborhood of ██████ becomes inaccessible: all access and escape routes are closed off by metallic fences made of steel rebars of the type used for building reinforcements. These fences come out from the walls of the buildings, cross the road between them, and penetrate into the adjoining building.
7:34 AM Although the neighborhood is inaccessible, beyond the fences several corpses are visible. Most of them, despite being in the street, are wearing unsuitable garments for public use, such as pajamas, bathrobes, underwear. The bodies appear pierced by numerous twisted steel rebars, mainly in the cephalic or sternal area, and many have also been traversed in the proximal portion of the legs, particularly in the femoral area. This type of attack is performed by SCP-024-IT, presumably in order to prevent the victim from escaping.
11:41 AM The area is secured by agents of the Foundation. The area is henceforth labeled as locus-024.
11:57 AM Agent P███ S██████ crosses over one of the fences; some bars of the same fence begin to move autonomously with serpentine movements and agent S██████ is pierced by 3 steel bars in the femoral area (2) and in the jugular area (1). The agents who run in his aid are attacked as well, but they are able to dodge attacks that extend for less than a meter beyond the fence; however, they are unable to get close. The self-propelled bars are henceforth labeled as SCP-024-IT.
12:09 PM Agent S██████ stops moving. Later the cause of death will be confirmed as being exsanguination.
12:41 PM Agent G██████ Z████ climbs over a roof and enters the locus-024 avoiding the fences. He is immediately attacked by several instances of SCP-024-IT that are completely free to move and crawl on the ground. Agent Z████ is injured by 4 attacks in the femoral (2), brachial (1) and retrosternal (1) areas, the latter being lethal.
A fence made of instances of SCP-024-IT. Picture taken at a safe distance from within the locus-024 by agent M████.
3:00 PM It is decided to send another agent inside the locus-024 to look for possible survivors and for further exploration of the anomalous area. Agent M██████ M████, equipped with a Kevlar suit and a reinforced integral helmet, climbs over a roof and enters the locus-024. The agent manages to dodge the attacks of SCP-024-IT; some attacks successfully hit the agent in the thoracic and femoral area but they do not result in being invalidated. Agent M████ attempts to use lethal force with her ordinance firearm, which is moderately effective in stopping instances of SCP-024-IT temporarily. Of the dozens of instances hit by the agent, 5 are broken by the bullet, and stop moving altogether; deactivated instances return to being inert and stop producing SCP-024-IT-M. It is not clear whether these instances can be reactivated or not.
3:09 PM Several instances stuck in the victims slip out of the bodies and proceed to search for agent M████. These instances have a higher concentration of SCP-024-IT-M on the surface and appear to be more reddish. They are also faster and more aggressive and they can coordinate with each other. Agent M████ undergoes several attacks in the femoral area by 3 instances that focus on the same spot, succeeding in penetrating the suit and making it impossible for the agent to walk further. Despite the agent's vocalizations of pain, a recovery action is impossible. The evaluation of an emergency plan is immediately put in place before the hemorrhagic leakage results in death for agent M████.
3:13 PM Agent M████ undergoes other coordinated attacks in the brachial area and in the cephalic area, succeeding in penetrating the overall suit and helmet. The cephalic attack results in death.
4:51 PM The SSM-IX "Machinamenta" arrives on site.
5:00 PM SSM-IX sends a drone inside the locus-024. The drone, despite flying at man's height, is not attacked by SCP-024-IT.
5:08 PM The drone identifies a kneeling man in a relatively central area, which is alive and does not appear to be injured. Immediately afterwards the rotors stop working and the drone falls to the ground. This position is labeled as ℒ1.
5:34 PM SSM-IX sends into the locus-024, the gynoid DIVINA which is able to cross over one of the fences without being attacked.
5:44 PM DIVINA reaches ℒ1 and finds the previously identified man. He is wearing work clothes and is identified as Ernesto Moretti, a construction worker employed at a construction site in the area now turned into the locus-024. DIVINA asks Mr. Moretti for explanations about his presence there and why he was not attacked by SCP-024-IT. Mr. Moretti, in tears, only enunciates the phrase «I did not mean it», repeatedly. For the rest, although he interacts with DIVINA, he does not listen to the gynoid's requests.
5:53 PM Upon order of the Command of SSM-IX, DIVINA attempts to recover Mr. Moretti. Several instances of SCP-024-IT twist around Mr. Moretti's body in a non-hostile manner, preventing the gynoid from touching him, but without attacking it. Immediately after DIVINA falls to the ground; the sensors are still active, but the servomotors do not respond; subsequent analyses, performed both on the drone and on DIVINA, revealed the formation of SCP-024-IT-M within them. Once cleansed, the machines started working again regularly.
7:08 PM SSM-IX knocks down a fence with a heavy-duty fixed turret. Agent Gianluca Laudanna, equipped with a powered exoskeleton, enters into the locus-024 before other SCP-024-IT instances are able to arrive and reconstruct the fence.
7:13 PM Agent Laudanna is fiercely attacked by numerous instances of SCP-024-IT. Many attacks are successful, but the exoskeleton is sufficient to protect the agent's body. The agent is able to neutralize several instances by using his assault rifle, whose large aperture allows a higher hit ratio.
7:27 PM Agent Laudanna arrives close to point ℒ1. While approaching the last alley before the location, several instances of SCP-024-IT, presumably formerly part of the reinforced concrete of the two buildings at the sides of the alley, emerge from the buildings and form a fence that prevents access. The agent gets around buildings, but when he comes again close to ℒ1, the same phenomenon occurs.
7:50 PM After repeated attempts, Agent Laudanna is forced to abandon the operation because following the attacks from SCP-024-IT the exoskeleton has been damaged in multiple points and the agent reports that it does not move correctly; successive analyses will reveal that the servomotors were accumulating SCP-024-IT-M inside themselves.
8:14 PM Agent Laudanna exits the locus-024, having suffered several injuries where the armor cracked. The agent reports that he heard the sound of a gunshot as he was about to retire.
9:48 PM SSM-IX starts purge operations of the locus-024. The squad agents are sent hunting for the instances, in a group and equipped with large aperture and explosive weapons, following a spiraling path. Turrets and other agents are positioned to guard all possible exit routes from locus-024 to terminate potential instances attempting to flee.
Post mortem x-ray of agent M████. The instance of SCP-024-IT (neutralized) is clearly visible.
201█-07-12 5:02 AM After all night, locus-024 is now purged of the SCP-024-IT infestation. ██ instances have been acquired still functional and are sent to Site Vulcano.
5:09 AM Recovery operations of the victims are commenced.
5:47 AM The bodies of agents S██████, Z████ and M████ are retrieved.
6:04 AM DIVINA and Mr. Moretti's body are retrieved. Mr. Moretti has a lethal gunshot wound in the occipital-temporal area and holds a drum gun in his hand.
6:12 AM Following the inspection of Mr. Moretti's clothes, a note is recovered. In its smartphone, 4 SMS messages are also retrieved in a format that should not be compatible with that phone model. For details on the finds see the Materials of Interest below.
8:30 AM The clean-up phase of the locus-024 is completed and it is commenced the search for civilian witnesses for the administration of amnestics and confiscation of audiovisual material documenting the existence of SCP-024-IT.

I am building (have build) Arduino based energy monitor. I can't get 5V out of Arduino. I only get about 4.8V. So at the mid point I get only ~2.2-2.3V.
The question is how critical is to have exactly 2.5v at the mid point? And what are the consequences if I can't get exactly 2.5V?
Please advise,
Ramunas
Re: how critical is to have exactly 2.5v at the mid point
The purpose of the mid-point reference voltage is so that the signal to be measured can swing to either side of it. If the reference is slightly away from the mid-point, it just means that the peaks of your AC signal will hit the end-points of the measurement range a bit sooner that they would otherwise have done for a signal of the same amplitude.
Providing that your reference voltage before remains constant, the maths will remove any DC content, regardless of its absolute level.
Re: how critical is to have exactly 2.5v at the mid point
thanks for the reply Calypo. I am using LM358 to stabilize the mid point voltage so I hope that it will remain constant.
So I guess the reason that my inputs are sensing some current with no loads attached (from 0.3-0.8A) has nothing to do with my mid point voltage being about 0.2-0.3v off.
Re: how critical is to have exactly 2.5v at the mid point
Correct. What you are seeing there is almost certainly noise from the digital side of the processor leaking into the analogue side - we think the likeliest route is via the analogue supply and analogue reference.
Re: how critical is to have exactly 2.5v at the mid point
Robert - sorry but I am not sure what you mean by "via the analogue supply and analogue reference".
I have my Arduino powered from Beagle Bone via USB cable. Is there any way to clean up that noise that I am seeing?
Re: how critical is to have exactly 2.5v at the mid point
Probably not. I obviously didn't know what you were using, it was possible that you had designed your own PCB. The processor has separate pins for these functions, and the manufacturer (Atmel) recommends filtering between the digital and analogue supplies. As far as I know, only a few Arduino boards have any filtering, and anecdotally most complaints of noise seem to come from users of Arduino plus Shield, or Arduino plus plugboard front-end.
If you use an ac voltage input and calculate real power, then you will see an improvement because the maths of the rms current calculation rectifies all the noise, whereas in the real power calculation, current is multiplied by voltage and then averaged, so much of the noise averages out and disappears.
Re: how critical is to have exactly 2.5v at the mid point
I did constructed my own PCB. My PCB holds 2 inputs for the 100A CT's and 5 inputs for 30A CT's as well as AC voltage sensing circuit. I can add the pictures of the PCB if that helps. I do calculate realPower.
So I guess the question is, is there a way to filter the noise? Or should I even worry about it? The reason I am asking is that the readings that I receive from my rig does not match with the "Kill a watt" meter or the portable current clamp meters. The difference is almost 1A at the low end (hard to measure in high end). For the 30A CT's I have calibration at 30, and for the 100A CT's I have calibration set to 58.8 with the 33 oms resistors.
Re: how critical is to have exactly 2.5v at the mid point
Clearly, you are worried about the noise. Are you using your own PCB design or an Arduino, or is it your design of front end feeding into the analogue inputs of an Arduino? There is a lot of information on the Atmel website that, if you have not seen it, is worth looking at.
I am guessing that you are seeing the 0.8 A on the 100 A inputs, so less than 1%. Even so, the emonTx can normally do better than that. But what is the maximum power that you can measure, and what is the noise power that you are seeing? How does that correlate with the 0.8 A? I would be very surprised if it does, for the reason I gave in a previous post.
Re: how critical is to have exactly 2.5v at the mid point
I have my Arduino powered from Beagle Bone via USB cable.
A very common source of ADC noise is a ripply Vcc supply. As an experiment, you could try powering your Arduino via it's DC-IN jack at a higher voltage thereby using the onboard regulator to produce the Vcc.... most of them are pretty clean. There's more on that here: http://openenergymonitor.org/emon/node/10111
Re: how critical is to have exactly 2.5v at the mid point
Thanks for the interesting link. I will experiment with that. When I was trying to get my voltage exactly at 5v I had 12v power connected to DC-IN. I noticed that the part next to the jack (voltage regulator I am guessing) was getting very hot. I am not sure if that is the problem or just normal operation to cut down 7v...
My only issue is, how would I record the data if I am not connected to USB. Is there any way to connect to serial without USB? I guess displaying on LCD screen is one option.
Re: how critical is to have exactly 2.5v at the mid point
Hi Robert,
I am using Arduino Mega and my own soldered PCB to connect the CT's and Voltage input. I will take a look at Atmel website.
I believe so that I was seeing 0.8 on the 100A inputs (it would be nice if I can downsize the inputs to 50A since the whole house will never use 100A). On the 30A input, currently CT's are attached to the wires in fuse box on the water heater. With the heater not running I am seeing fluctuation from 1.9 to 9 watts. I will try to run another test with CT's disconnected and power from DC-IN once I figure out how to capture the data.
thanks,
Ramunas
Re: how critical is to have exactly 2.5v at the mid point
To change from 100 A max. to 50 A max, you can double the value of your burden resistor.
Re: how critical is to have exactly 2.5v at the mid point
My only issue is, how would I record the data if I am not connected to USB.
Most Arduino designs let you use the USB for data while still powering the Arduino via the DC-IN jack. But power distribution is an area that every Arduino designer tends to do their own thing, some better than others, so you really need to check the schematic for your exact Arduino to see if they've handled it properly.
The EtherMega I used in the experiments in the link above has a very simple but effective 3-way jumper that allows you to tie Vcc to the output of the on-board DC-in regulator, or to the USB 5V, but never both. Other designs use comparators to only switch the USB 5V through if there's no voltage found on the DC-in input.
Re: how critical is to have exactly 2.5v at the mid point
Do you know if the accuracy will improve by reducing the range only up 50 A
Is there any way to reduce the range for the 30A CT's that do not have any burden resistors?

I do not think that my Arduino has the jumpers to select the power but I will inspect it when I get home. I will experiment with different options.
thanks for the info.
Re: how critical is to have exactly 2.5v at the mid point
"Do you know if the accuracy will improve by reducing the range only up 50 A"
The best way would be to leave the original burden resistor and use a 2-turn primary winding for your CT - but the cable size/CT aperture combination might not allow that. That is because the CT will still be working at the design flux density. The next best is to double the resistance of the burden. Both will reduce the noise (pro rata) but the second will marginally worsen the accuracy, the first is preferred.
"Is there any way to reduce the range for the 30A CT's that do not have any burden resistors?"
The 30 A CTs do have burden resistors, but they are internal. If you have the YHDC SCT-013-030, then as far as I know, that is identical to the -000 except that the -000 has zener diodes inside the casing to protect against over-voltage, which are unnecessary if the burden resistor is internal and cannot be disconnected. The CT is quite easy to disassemble, and if you have a suitable SMT resistor, you could change that. The CT secondary gives you 15 mA @ 30 A, you want about 1.66 V rms (no more) at whatever maximum current you decide, so calculate the burden value from that. Or you could convert it into a -000 by removing the burden resistor and fitting a pair of 8.2 V zener diodes and use an external burden resistor. If you don't want to do either, then without going to a 2-turn primary (15 A max), there's nothing you can do.
Re: how critical is to have exactly 2.5v at the mid point
So yesterday I did some experimenting with different power supplies to see how much noise I am getting from the power. This is the pics of what my rig looks like.
To measure the noise, I was using Robin's minManAndRangeChecker.ino
Here the results max indicates the bigest difference between min and max:
Arduino Mega 2560
Powered from DC-IN via 12v battery max variance max 3
Powered from DC-IN via 12v WD HDD power adapter max 31
Powered from DC-IN via 12v sec cam power adapter max 73
Powered from DC-IN via 12v sec cam power adapter max 34 interesting since it's identical adapter...
Powered from DC-IN via 12v sec cam power adapter max 80
Powered from DC-IN via 12v cable modem adapter max 370
powered from usb via BBB variance max 25
powered from usb via my computer variance max 18
powered from usb via Black Berry blk usb var max 13
powered from usb via Black Berry wht usb var max 15
powered from usb via Verizon usb variance max 15
powered from usb via Wasabi Power GoPro variance max 52
powered from usb via cut usb cable to old power max 21 (but for the most part would stay below 10)
I was surprised how differently the power adapters performed. The 2 best options were Black Berry USB chargers and old transformer based 5.2V power adapter (I cut USB cable and powered it that way).
After I scratched my head for 30 mins on why I am still getting such a high differences, since my first prototype on UNO with no LM and 10uf caps was getting only difference of 3. I decided to add a 10uf capacitor from the ground to buffered 2.5V. As soon as I added the capacitor, differences decreased to about 2-3. See the pic, this is in Watts. Tot: is the sum of 2 100A CT's and Water: is the sum of 2 30A CTs. The rest are 30A CTs.
I say not too bad. So after letting it run for a while this is what emoncms is showing:
I think at this point, I am happy with my nose levels. I just hope the added 10uf capacitor won't affect the accuracy of the CT's.
Thanks everyone, for your input and help!
Re: how critical is to have exactly 2.5v at the mid point
"I just hope the added 10uf capacitor won't affect the accuracy of the CT's."
How can it? That 2.5 V rail is supposed to be a ground to ac signals, so making it even more grounded will only affect the accuracy in a positive way.
But the need to add the capacitor does suggest that the op.amp. is marginally stable or even oscillating.
Re: how critical is to have exactly 2.5v at the mid point
But the need to add the capacitor does suggest that the op.amp. is marginally stable or even oscillating.
how can I verify if op.amp is stable and doing what it suppose to do?

Kratom Notes
8:15 - Smoke one small leaf off a Kratom plant, No rush per say but a definite alteration of mental state upon smoking. Smoke isn't harsh, very mild pleasant. Tastes like oregano but milder.
8:20- Decrease in body sensations/ pain killer effect like Vicodin
8:25- Effects seem VERY similar to cocaine but with more pain killer properties. Agitated must move. Prune salvia plants. Pace around the room. Smoke another leaf while pacing around the room
8:41- Where has the time gone? I could swear it was only 8:30. I begin typing this. Energized and agitated, the experience seems limited like cocaine. I want more but don't want to mix this with anything. No music enhancement, no visuals, clear head. This seems like another anti-entheogen like cocaine. No enlightenment just agitation.
No way could I sleep on this. This may be good if I needed to stay awake to study. I want to type so fast I don't care about grammar at all. Maybe it would be good for studying but not writing.
8:45- Mild tactile increase. Lower than normal sex drive. I may be on the verge of a headache. Maybe I should masturbate just to see if it may increase orgasm.
8:52- I'm eating some pizza. This stuff isn't suppressing my appetite.  Food tastes like cardboard but I'm still hungry.
8:55- Smoke another hit. I feel a little psychedelic in this now around the edges but not much. Food feels weird in my mouth like on mushrooms, but still no visuals at all. This must not be very visual at all because even weed gives me visuals and if they were to be found I would have found them by now. Hands feel like rubber. I'm going to masturbate just to see if it feels any different
9:07 - Finish masturbating. Erection was slightly difficult because of lack of sex drive. Orgasm was significantly increased however and my face felt hot/flushed and my heart beat rapidly for a few minutes after. I still feel agitated like there is something I should be doing or some other drug I could combine this with to make it more interesting.
9:20- I feel that I the stimulant effects are wearing off. I'm going to do a balloon of Nitrous and see how that works.
9:24- Nitrous intoxication is significantly enhanced, more than ever before, while on Kratom. I had some incredible insights into my psyche, mostly unpleasant.
9:35- I'm leaving for a party with GBL in a bottle of coke. More later.
By the time I arrived at the party the effects of the Kratom had worn down almost completely. There were no strange interactions with the GBL, as there are when combining GBL with alcohol or other depressant drugs, in fact the GBL may have had a slightly lessened effect on me. However, the GBL provided a nice end to the experience. Overall I'd say the experience is worth repeating although next time I'd like to try chewing the leaves instead of smoking them to see if the effects are different.

Troubleshooting Guide
Oh no! You're having trouble? Below is a list of solutions to common problems.
Route rules have no effect on my application
If route rules are working perfectly for the Bookinfo sample, but similar version routing rules have no effect on your own application, it may be that your Kubernetes services need to be changed slightly.
Kubernetes services must adhere to certain restrictions in order to take advantage of Istio's L7 routing features. Refer to the sidecar injection documentation for details.
Verifying connectivity to Istio Pilot
Verifying connectivity to Pilot is a useful troubleshooting step. Every proxy container in the service mesh should be able to communicate with Pilot. This can be accomplished in a few simple steps:
-
Get the name of the Istio Ingress pod:
$ INGRESS_POD_NAME=$(kubectl get po -n istio-system | grep ingress\- | awk '{print$1}')
-
Exec into the Istio Ingress pod:
$ kubectl exec -it $INGRESS_POD_NAME -n istio-system /bin/bash
-
Test connectivity to Pilot using cURL. The following example cURL's the v1 registration API using default Pilot configuration parameters and mTLS enabled:
$ curl -k --cert /etc/certs/cert-chain.pem --cacert /etc/certs/root-cert.pem --key /etc/certs/key.pem https://istio-pilot:15003/v1/registration
If mTLS is disabled:
$ curl http://istio-pilot:15003/v1/registration
You should receive a response listing the “service-key” and “hosts” for each service in the mesh.
No traces appearing in Zipkin when running Istio locally on Mac
Istio is installed and everything seems to be working except there are no traces showing up in Zipkin when there should be.
This may be caused by a known Docker issue where the time inside containers may skew significantly from the time on the host machine. If this is the case, when you select a very long date range in Zipkin you will see the traces appearing as much as several days too early.
You can also confirm this problem by comparing the date inside a docker container to outside:
$ docker run --entrypoint date gcr.io/istio-testing/ubuntu-16-04-slave:latest
Sun Jun 11 11:44:18 UTC 2017
$ date -u
Thu Jun 15 02:25:42 UTC 2017
To fix the problem, you'll need to shutdown and then restart Docker before reinstalling Istio.
Envoy won't connect to my HTTP/1.0 service
Envoy requires HTTP/1.1 or HTTP/2 traffic for upstream services. For example, when using NGINX for serving traffic behind Envoy, you will need to set the proxy_http_version directive in your NGINX config to be “1.1”, since the NGINX default is 1.0
Example config:
upstream http_backend {
server <IP_ADDRESS>:8080;
keepalive 16;
}
server {
...
location /http/ {
proxy_pass http://http_backend;
proxy_http_version 1.1;
proxy_set_header Connection "";
...
}
}
No Grafana output when connecting from a local web client to Istio remotely hosted
Validate the client and server date and time match.
The time of the web client (e.g. Chrome) affects the output from Grafana. A simple solution to this problem is to verify a time synchronization service is running correctly within the Kubernetes cluster and the web client machine also is correctly using a time synchronization service. Some common time synchronization systems are NTP and Chrony. This is especially problematic is engineering labs with firewalls. In these scenarios, NTP may not be configured properly to point at the lab-based NTP services.
Where are the metrics for my service?
The expected flow of metrics is:
- Envoy reports attributes to Mixer in batch (asynchronously from requests)
- Mixer translates the attributes from Mixer into instances based on operator-provided configuration.
- The instances are handed to Mixer adapters for processing and backend storage.
- The backend storage systems record metrics data.
The default installations of Mixer ship with a Prometheus adapter, as well as configuration for generating a basic set of metric values and sending them to the Prometheus adapter. The Prometheus add-on also supplies configuration for an instance of Prometheus to scrape Mixer for metrics.
If you do not see the expected metrics in the Istio Dashboard and/or via Prometheus queries, there may be an issue at any of the steps in the flow listed above. Below is a set of instructions to troubleshoot each of those steps.
Verify Mixer is receiving Report calls
Mixer generates metrics for monitoring the behavior of Mixer itself. Check these metrics.
-
Establish a connection to the Mixer self-monitoring endpoint.
In Kubernetes environments, execute the following command:
$ kubectl -n istio-system port-forward <mixer pod> 9093 &
-
Verify successful report calls.
On the Mixer self-monitoring endpoint, search for
grpc_server_handled_total
.You should see something like:
grpc_server_handled_total{grpc_code="OK",grpc_method="Report",grpc_service="istio.mixer.v1.Mixer",grpc_type="unary"} 68
If you do not see any data for grpc_server_handled_total
with a
grpc_method="Report"
, then Mixer is not being called by Envoy to report
telemetry. In this case, ensure that the services have been properly
integrated into the mesh (either by via
automatic
or manual sidecar injection).
Verify Mixer metrics configuration exists
-
Verify Mixer rules exist.
In Kubernetes environments, issue the following command:
$ kubectl get rules --all-namespaces NAMESPACE NAME KIND istio-system promhttp rule.v1alpha2.config.istio.io istio-system promtcp rule.v1alpha2.config.istio.io istio-system stdio rule.v1alpha2.config.istio.io
If you do not see anything named
promhttp
orpromtcp
, then there is no Mixer configuration for sending metric instances to a Prometheus adapter. You will need to supply configuration for rules that connect Mixer metric instances to a Prometheus handler.
-
Verify Prometheus handler config exists.
In Kubernetes environments, issue the following command:

How can I debug issues with the service mesh?
With istioctl
Istioctl allows you to inspect the current xDS of a given Envoy from its admin interface (locally) or from Pilot using the proxy-config
or pc
command.
For example, to retrieve the configured clusters in an Envoy via the admin interface run the following command:
$ istioctl proxy-config endpoint <pod-name> clusters
To retrieve endpoints for a given pod in the application namespace from Pilot run the following command:
$ istioctl proxy-config pilot -n application <pod-name> eds
The proxy-config
command also allows you to retrieve the state of the entire mesh from Pilot using the following command:
$ istioctl proxy-config pilot mesh ads
With GDB
To debug Istio with gdb
, you will need to run the debug images of Envoy / Mixer / Pilot. A recent gdb
and the golang extensions (for Mixer/Pilot or other golang components) is required.
-
kubectl exec -it PODNAME -c [proxy | mixer | pilot]
-
Find process ID: ps ax
-
gdb -p PID binary
-
For go: info goroutines, goroutine x bt
With Tcpdump
Tcpdump doesn't work in the sidecar pod - the container doesn't run as root. However any other container in the same pod will see all the packets, since the network namespace is shared. iptables
will also see the pod-wide config.
Communication between Envoy and the app happens on <IP_ADDRESS>, and is not encrypted.
Envoy is crashing under load
Check your ulimit -a
. Many systems have a 1024 open file descriptor limit by default which will cause Envoy to assert and crash with:
[2017-05-17 03:00:52.735][14236][critical][assert] assert failure: fd_ != -1: external/envoy/source/common/network/connection_impl.cc:58
Make sure to raise your ulimit. Example: ulimit -n 16384
Headless TCP services losing connection from Istiofied containers
If istio-citadel
is deployed, Envoy is restarted every 15 minutes to refresh certificates.
This causes the disconnection of TCP streams or long-running connections between services.
You should build resilience into your application for this type of
disconnect, but if you still want to prevent the disconnects from
happening, you will need to disable mTLS and the istio-citadel
deployment.
First, edit your istio config to disable mTLS
$ kubectl edit configmap -n istio-system istio
$ kubectl delete pods -n istio-system -l istio=pilot
Next, scale down the istio-citadel
deployment to disable Envoy restarts.
$ kubectl scale --replicas=0 deploy/istio-citadel -n istio-system
This should stop Istio from restarting Envoy and disconnecting TCP connections.
Envoy Process High CPU Usage
For larger clusters, the default configuration that comes with Istio refreshes the Envoy configuration every 1 second. This can cause high CPU usage, even when Envoy isn't doing anything. In order to bring the CPU usage down for larger deployments, increase the refresh interval for Envoy to something higher, like 30 seconds.
$ kubectl edit configmap -n istio-system istio
$ kubectl delete pods -n istio-system -l istio=pilot
Also make sure to reinject the sidecar into all of your pods, as their configuration needs to be updated as well.
Afterwards, you should see CPU usage fall back to 0-1% while idling. Make sure to tune these values for your specific deployment.
Warning:: Changes created by routing rules will take up to 2x refresh interval to propagate to the sidecars. While the larger refresh interval will reduce CPU usage, updates caused by routing rules may cause a period of HTTP 404s (up to 2x the refresh interval) until the Envoy sidecars get all relevant configuration.
Kubernetes webhook setup script files are missing from 0.5 release package
The 0.5.0 and 0.5.1 releases are missing scripts to provision webhook certificates. Download the missing files from here and here. Subsequent releases (> 0.5.1) include these files.
Automatic sidecar injection will fail if the kube-apiserver has proxy settings
This was tested on 0.5.0 with the additional files required as referenced in the above issue. When the Kube-apiserver included proxy settings such as:
env:
- name: http_proxy
value: http://proxy-wsa.esl.foo.com:80
- name: https_proxy
value: http://proxy-wsa.esl.foo.com:80
- name: no_proxy
value: <IP_ADDRESS>,localhost,dockerhub.foo.com,devhub-docker.foo.com,<IP_ADDRESS>,<IP_ADDRESS>,<IP_ADDRESS>
The sidecar injection would fail. The only related failure logs was in the kube-apiserver log:
W0227 21:51:03.156818 1 admission.go:257] Failed calling webhook, failing open sidecar-injector.istio.io: failed calling admission webhook "sidecar-injector.istio.io": Post https://istio-sidecar-injector.istio-system.svc:443/inject: Service Unavailable
Make sure both pod and service CIDRs are not proxied according to *_proxy variables. Check the kube-apiserver files and logs to verify the configuration and whether any requests are being proxied.
A workaround is to remove the proxy settings from the kube-apiserver manifest and restart the server or use a later version of kubernetes.
An issue was filed in kubernetes related to this and has since been closed. https://github.com/kubernetes/kubeadm/issues/666 https://github.com/kubernetes/kubernetes/pull/58698#discussion_r163879443

Assignment by Marty Stepp and Victoria Kirst. Based on a problem by Stuart Reges of U of Washington.
March 3, 2017
This problem focuses on Binary Trees. This is an individual assignment. Write your own solution and do not work in a pair/group on this program.
In this problem you will implement a yes/no guessing game called "21 Questions." This problem can be thought of as an enhanced version of the "20 Questions" problem you solved in a previous assignment, where this version uses your new knowledge of binary trees to make the game more interesting. You can certainly use your own code from the previous assignment to help you write this problem, though this new version is different enough that your code will need significant modifications.
Specifically, this version of the game has the following new major features:
As before, each round of the game begins by you (the human player) thinking of an object. The computer will try to guess your object by asking you a series of yes-or-no questions. Eventually the computer will have asked enough questions that it thinks it knows what object you are thinking of, so it will make a final guess about what your object is. If this guess is correct, the computer wins; if not, you win. For example, the computer might decide to ask the following series of questions to figure out what the player is thinking of:
Is it an animal? y Can it fly? n Does it have a tail? y Does it squeak? n Are you thinking of: lion? y Hooray, I win!
In the previous version of this game that you implemented, you did not store the game's questions and answers in any particular data structure; you read the input from a file line-by-line to play the game. In this version of our game, the computer keeps track of a binary tree whose nodes represent the game's questions and answers. Every node's data is a string representing the text of the question or answer. A "question" node contains a left "yes" subtree and a right "no" subtree. An "answer" node is a leaf in the tree. The idea is that this tree can be traversed to ask the human player a series of questions. (Like before, though the game is called "21 Questions," our game will not limit the tree to a height of 21; any number of questions will be allowed.)
For example, in the tree below, the computer would begin the game by asking the player, "Is it an animal?" If the player says "yes," the computer goes left to the "yes" subtree and then asks the user, "Can it fly?" If the user had instead said "no," the computer would go right to the "no" subtree and then ask the user, "Does it have wheels?"
This pattern continues until the game reaches a leaf "answer" node. Upon reaching an answer node, the computer asks whether that answer is the correct answer. If so, the computer wins.
yes = left root no = right | | Q:Is it an animal? ____/ \____ ____/ \____ / \ Q:Can it fly? Q:Does it have wheels? / \ / \ / \ / \ A:bird Q:Does it have a tail? Q:Does it have an engine? Q:Is it nice? / \ / \ / \ / \ / \ / \ Q:Does it squeak? A:spider A:car A:bicycle A:SL A:teacher / \ / \ A:mouse A:lion
In this version of the game, the computer expands its set of possible answers (with the human's help) each time it loses a game. Specifically, if the computer's answer guess is incorrect, you the human player must tell it a new question it can ask to help it do better in future games. For example, suppose in the preceding log that the player was not thinking of a lion, but of an elephant. The game log would look like this:
Is it an animal? y Can it fly? n Does it have a tail? y Does it squeak? y Are you thinking of: lion? n Drat, I lost. What was your object? elephant Type a Y/N question to distinguish elephant from lion: Does it have a trunk? And what is the answer for elephant? yes
The computer takes the new information from the lost game and uses it to grow its tree of questions and answers. You must replace the old incorrect answer node with a new question node that has the old incorrect answer and new correct answer as its children. For example, after the game represented by the preceding log, the computer's overall game tree would be the following:
yes = left root no = right | | Q:Is it an animal? ____/ \____ ____/ \____ / \ Q:Can it fly? Q:Does it have wheels? / \ / \ / \ / \ A:bird Q:Does it have a tail? Q:Does it have an engine? Q:Is it nice? / \ / \ / \ / \ / \ / \ Q:Does it squeak? A:spider A:car A:bicycle A:SL A:teacher / \ / \ A:mouse Q:Does it have a trunk? / \ / \ A:elephant A:lion
In the previous version of this problem you wrote a free-standing function to play the question game.
Since this version has a more complex state and game flow, you will instead write your code in a class named QuestionTree
.
You will use a provided structure QuestionNode
to represent each node of the question tree.
You are also provided with a main client program that handles user interaction and calls your tree's member functions to play games.
Your question tree uses input files in the same format as the prior version of this problem, such as the example below. The order in which the lines are stored represents a preorder traversal of the question binary tree.
Q:Is it an animal? Q:Can it fly? A:bird Q:Does it have a tail? Q:Does it squeak? A:mouse A:lion A:spider Q:Does it have wheels? Q:Does it have an engine? A:car A:bicycle Q:Is it nice? A:section leader A:teacher
Q:Is it an animal? | y-- Q:Can it fly? | | | y-- A:bird | | | n-- Q:Does it have a tail? | | | y-- Q:Does it squeak? | | | | | y-- A:mouse | | | | | n-- A:lion | | | n-- A:spider | n-- Q:Does it have wheels? | y-- Q:Does it have an engine? | | | y-- A:car | | | n-- A:bicycle | n-- Q:Is it nice? | y-- A:section leader | n-- A:teacher
Your QuestionTree
must have the following public members listed in the table below.
Any function that traverses your binary tree must do so recursively; absolutely no loops are allowed on this problem in any part of your code.
You will find that some of the member functions below do not have the parameters you'll need to implement the desired recursive behavior.
In such cases you should not change our required function headers, but you may add extra "helper" functions as needed to help you implement the behavior.
Any member functions you add, along with all private member variables, must be declared private.
In the previous version of this problem, a single function performed two duties simultaneously:
You were reading the game's question-and-answer data from a file, and also playing the game with the user.
In this version of the problem, those two tasks are split into two member functions: readData
and playGame
.
In the old version of the problem, you sometimes wanted to "skip" around in the data to get to the next question to ask. That is no longer the case in this version of the problem. You do not need any "skipping" function because you can move left/right in your tree to get to the next question or answer. Note that no loops are allowed in any of the members below.
| QuestionTree member | Description |
|---|---|
QuestionTree() |
In this constructor you should initialize your question tree. At first the tree contains only a single node storing the answer "computer". In other words, if you were to create a question tree and then immediately begin playing the game, the computer would ask the following question: Are you thinking of: computer? |
~QuestionTree() |
In this destructor you should free all dynamically allocated memory for your tree and its question nodes. |
getGamesLost() |
In this member function you should return the number of games the computer has lost during this session. Initially 0 games have been played and won. A game is lost when the computer asks the user, "Are you thinking of: ___?" and the user says "no". |
getGamesWon() |
In this member function you should return the number of games the computer has won during this session. Initially 0 games have been played and won. A game is won when the computer asks the user, "Are you thinking of: ___?" and the user says "yes". |
playGame() |
In this member function you should play one complete game of 21 Questions with the user, walking your question tree from its root to an answer leaf node by asking a series of Yes/No questions. This function must be written recursively and must not use any loops.
You will find that this function is somewhat similar to the
Also note that if the computer loses the game, you must prompt for a new question and answer node and modify your question tree as appropriate.
That behavior is part of the responsibility of this function.
Note that the user can type any text they like for their new question and answer; the user won't type the
Yes/no prompts:
As with the last version of this problem, ask yes-or-no questions using the function
After the game is over, the provided |
readData(input) |
In this member function you should read question tree data from the given input stream (
Assume valid input:
You may assume that the input file exists, is readable, and is in the proper format described in this spec, with no blank lines or extraneous/invalid data.
Assume that each question will have exactly two children representing its "yes" and "no" options.
You may assume that each line of the file begins with Since you are loading new data and creating a new tree of question nodes, you must free memory for any previous nodes that were in the tree beforehand. Do not leak any memory from this function. This member function loads the question tree's data of questions and answers, but it does not load any record of the number of games won or lost. Nor does it change your question tree's count of total games won/lost. |
writeData(output) |
In this member function you should write question tree data to the given output stream ( This function saves the question tree's current data of questions and answers, but it does not save any record of the number of games won or lost. |
To help you implement your question tree, we provide a file questionnode.h that declares a structure called QuestionNode
to represent one binary tree node.
It has the following members.
Do not modify questionnode.h.
struct QuestionNode { string data; // question or answer text QuestionNode* yes; // pointer to "yes" subtree (left) QuestionNode* no; // pointer to "no" subtree (right) // constructor (all parameters are optional) QuestionNode(string data = "", QuestionNode* yes = nullptr, QuestionNode* no = nullptr); };
As in other assignments, you should follow our Style Guide for information about expected coding style. You are also expected to follow all of the general style constraints emphasized in the Homeworks 1-5 specs, such as the ones about good problem decomposition, parameters, using proper C++ idioms, and commenting. The following are additional points of emphasis and style contraints specific to this problem:
Binary tree usage: Part of your grade will come from appropriately utilizing binary trees and recursive algorithms to traverse them. Any functions that traverse a binary tree from top to bottom should implement that traversal recursively. We will check this particular constraint strictly; no exceptions!
Loops: Do not use any loops in any of your code on this part of the assignment.
Recursion: Part of your grade will come from appropriately utilizing recursion to implement your algorithm as described previously. We will also grade on the elegance of your recursive algorithm; don't create special cases in your recursive code if they are not necessary. Avoid "arm's length" recursion, which is where the true base case is not found and unnecessary code/logic is stuck into the recursive case. As mentioned previously, it is fine (sometimes necessary) to use "helper" functions to assist you in implementing the recursive algorithms for any part of the assignment.
Variables: The only member variables you should have on this problem are a pointer to the root of your question tree, and counters for the number of games won and lost. You should not declare any other member variables, nor should you declare any other static or 'global' variables.
Collections: Do not use any collections on this part of the assignment, other than your internal binary tree of nodes.
Memory usage:
Your code should have no memory leaks.
Do not allocate dynamic memory (new
) needlessly, and free the memory associated with any new objects you allocate internally once they are no longer being used.

Search Integration
RAMADDA can search both its own local repository as well as other sources of content - Google, YouTube, Wolfram/Alpha, DuckDuckGo, Flickr, etc.
By default only the local RAMADDA is searched. You can select what other search providers to use in the Search form under the "Where do you want to search?" tab.
To configure your RAMADDA to use a search provider you will need to install the Search plugin from the latest
release.
Once installed, a number of the search providers require an API key. To enable the provider retrieve the the key and add it to some
.properties file (e.g, keys.properties) in your RAMADDA home or plugins directory.
Flickr Image Search
Get an API key from
Flickr and define the RAMADDA property:
flickr.api.key=<your API key>
PLoS - Public Library of Science
Get a registration key at
http://api.plos.org/registration/ and set the property:
plos.api.key=<your API key>
Open Search
To add a new search provider that uses Open Search you need to configure a "classes.txt" file in your RAMADDA plugins directory. This specifies the Java class that does the search, the id of the provider and the URL template to use. The URL template should contain a "${searchterms}" macro.
You classes.txt file should look like:
#For open search the form is:
#classpath;ID;opensearch URL;Label
#The URL should have the macro: ${searchterms}
#
#e.g:
org.ramadda.plugins.search.OpenSearchProvider;nasa;https://api-test.echo.nasa.gov/opensearch/datasets.atom?keyword=${searchterms};NASA Open Search

You've gotta love hearing Vin Scully. In case you were wondering (I don't blame you if you weren't), Ryan Theriot is currently 7-20 with the Dodgers.

 In the winter, I am an avid
skier and novice snowhiker. During the warmer months here in Colorado, I enjoy mountain biking,
hiking, golfing, and running.
During the pandemic, I was forced indoors, I hauled all my math books, and computer
books, read some of it and planning to donate the rest.
Right now, I am spending a large amount of my free time exploring the latest
technology advancements in the front-end web development world.


Tips for using t.modal()
- You should only call t.modal() as a response to a user action, such as clicking a button.
- Try to use t.popup() when possible instead of t.modal() as it helps to better maintain context.
- Try to get your modal to load and render as quickly as possible.

title: More thoughts on WPF

keywords: wpf
teaser: Notes from my first experience using WPF, including its 3D features.
---
Hi, my name is Eric, and I am a coding addict.
When I founded SourceGear, I was a programmer. Nine years
later, my company has turned me into a marketing guy. After all the sacrifices
I made to get this company going, it has coldly turned its back on me, ignoring
my once prodigious programming talents, callously replacing me with people who
are younger and better looking, watching apathetically as my technical skills
atrophy each year, forgetting all the great things I have done, and ---
Ahem. Sorry, I got a little off track there. :-) Where
was I?
Ah yes, my addiction. You see, although my company has
grown to the point where it can no longer find a place for me as a coder, I
have found it rather difficult to stop. I've got some sort of an addiction, a
disease which compels me to write code. It is this mania which has driven me
to write things like my solitaire
game and my blogging
app. I pretty much always have some kind of a hobby project going on.
Lately my hours as a compulsive coder are spent working on
some ideas for woodworking design software. Since most of my readers are interested
in neither woodworking nor solid modeling, I'll spare you the gory details.
About five weeks ago I published a few of my early thoughts on WPF
(Windows Presentation Foundation, formerly called "Avalon"). My interest in
WPF continued to grow, so recently I decided to give it a try by writing a WPF
front end for my woodworking software. In the process of doing so, I am
becoming a WPF fan.
The screen shot below is a picture of my WPF viewer in
action:
Basically, my woodworking software is designed around the
concept of a list of steps. Each step corresponds to one woodworking action,
such as cutting a board or attaching two boards together. A primary job of the
software is to draw a picture of how the project will look at each step.
In the screen shot above, the ListView on the left contains
all of the steps to build a simple bookshelf. The larger 3D picture on the
right is showing the currently selected step.
I am certainly still not an expert on WPF, but here is what
I like so far:
- It is so easy to put cool things into a ListView. In
Win32, list controls are very oriented toward text. WPF has no such
bias. I wanted my ListView control to have a little preview picture of
each step. This was really simple to do with WPF.
- WPF 3D is far simpler to use than Managed DirectX.
That's kind of a remarkable thing to say when you consider that Managed
DirectX is far simpler than using DirectX from unmanaged code. I
was able to get excellent results from the 3D features of WPF in very little
time.
- Obviously, there are tradeoffs. For example, I haven't
found a way to do volumetric textures using the 3D features in WPF.
Still, those tradeoffs seem worth the trouble.
- I haven't tried it yet, but apparently WPF is supposed to
be able to print my 3D stuff. That's a pretty big win, since I
expected printing support to be a heckuva lot of work.
- I have found XAML to be very nice, after I got past the
initial learning curve.  It didn't take too long to find myself just typing tags and
attributes.
- The Visual Studio support for WPF and XAML is more useful
than I thought. The visual UI designer is basically useless, but
installing "Cider" also adds other WPF support to Visual Studio 2005,
including special project actions and Intellisense.
- The WPF samples in the Windows SDK are quite helpful.
- The WPF documentation? Not so much.
- Since everything in WPF is built on DirectX, controls and
3D stuff don't seem to mind sharing the screen with each other. When I
was using Managed DirectX with Windows Forms, I couldn't find any easy way
to have my 3D view show up in the same window as my controls. With WPF,
this is trivial. As the screen shot shows, I have my Viewport3D in the
same window as a couple of ListView controls.
- Finally, here is the coolest example of how smooth this
integration is:
- The preview pictures in the ListView are actually not
pictures -- they are little Viewport3D objects.
- With the Trackball class from Daniel Lehenbauer,
I can use the mouse to rotate and zoom the model.
- I have hooked up all the little viewports in the ListView
to the same Trackball as the main view. So, when I rotate or zoom the
model on the right, those little previews in the ListView are
automatically updated as well.
- This is what I call Deeply Neato. It's easier to appreciate
when you watch it happen, so I captured a short movie (4.5
MB AVI, 12 seconds).
Anyway, I suppose I will soon bump into some sort of a wall,
but so far, I think WPF is really nice.
