Infrastructure contractors and suppliers largely unscathed by Frontier's bankruptcy
In Frontier Communications' Chapter 11 bankruptcy filing late Tuesday, the company said it expects to continue providing "quality service to its customers without interruption and work with its business partners as usual throughout the court supervised process."
The company offers internet services in 29 states and is expected to complete the sale to Northwest Fiber by the end of this month for $1.4 billion for its operations in Washington, Oregon, Idaho and Montana.
The company, with roughly $17.5 billion in debt has approximately 2.6 million Internet subscribers with 1.4 million receiving services on DSL and 1.2 million on fiber.
In a statement, Frontier stated it would continue service uninterrupted to its 4.1 million customers that subscribe to its telephone, broadband and TV services.
Goldman Sachs Group has arranged $460 million in "debtor-in-possession" financing for Frontier to continue operating during the bankruptcy process.
In its financial restructuring plan announcement, Frontier said they were attempting to reduce their debt by over $10 billion.
Frontier's 50 largest creditors with unsecured claims are primarily noteholders, with the largest trade vendor being PeopleScout MSP, a staffing software company which is owed $5.3 million. AT&T is listed as being owed $2.6 million.
Underground utility service locator company USIC is owed $2.1 million with suppliers Anixter and Nokia of America Corporation at $1.8 million and $1.5 million.
Arris Solutions Inc. is owed $819,000. The company was acquired by CommScope in 2018.
JH Sulenfuss, Inc., a Tampa, Florida general contractor is due $781,000.
Litigants in a class-action wage lawsuit in California are identified as being owed $4.7 million as a result of a settlement.
In response to the Frontier announcement, FCC Wireline Competition Bureau Chief Kris Monteith said, "Staying connected to reliable telephone and Internet services is essential in today's America— perhaps never more so than during this unprecedented time as we confront the coronavirus pandemic. As such, I am pleased that Frontier has made clear that consumers will remain connected despite Frontier's filing of a bankruptcy reorganization plan."
"As the company undertakes this process, we expect it to comply with all Commission regulatory obligations. We will be vigilant in ensuring both that Frontier's customers stay connected to vital 911, voice, and broadband services and that Frontier continues to put the federal funds it receives through the Connect America Fund and other universal service programs to work for the American people," Monteith said in a statement.

Q: How to make Squid log url and forward traffic without proxying? I want to use squid to listen on port 80 and log all url requests and simply forward it to original destination without changing anything. How to achieve that?

A: Well, what you want to do is called proxying, so maybe what you meant was to make Squid invisible and disable any caching features ?
If so, disable caching by removing all cache_dir and refresh_pattern directives from the configuration file, and add the following to make the proxy invisible to the eyes of the web servers :
forwarded_for transparent
via off

The first directive prevents Squid from altering the X-Forwarded-For header, so it doesn't tamper with the request in any way; the second prevents it from adding the Via header with its name and version, again to be as subtle and discreet as possible.

How can we respond to a world of cascading disasters?
Over the past past few years we've had to deal with all sorts of new or resurgent evils, including climate catastrophe, Covid and the global assault on democracy. That's been made harder by the fact that our political leaders (and plenty of their supporters) have either failed to respond effectively, or have actively promoted these evils. Yet there's nothing positive about giving in to despair, either politically or personally.
In trying to respond, I've started thinking about the idea of 'mitigated disaster'. Despite our collective failures on all of these issues, there's still a good chance that the worst of the catastrophe will be staved off. And individually, we need to find ways to act responsibly and to resist the
As usual, 26 January has been marked by protests, denunciations of those protests, and further iterations. Even apart from the fact that it marks an invasion, the foundation of a colony that later became one of Australia's states isn't much of a basis for a national day.
A logical choice would be the day our Federation came into force. Unfortunately for this idea, our Founders chose 1 Jan 1901. The first day of the 20th century[1] must have seemed like an auspicious choice for a new country, but it ruled out the anniversary as a national day.
The ideal thing would be to fix the problems of our current system with a republican constitution including a treaty with the original owners of our land. That would provide a date really worthy of celebration.
In the meantime, I
Why it's vital to present a model before we vote
Shorter JQ: Albanese should release draft legislation before the Voice referendum if it is to succeed. Not doing so is a recipe for failure based in part on a mistaken analysis of the 1990s Republic referendum, which I shared for a long time.
Although polls suggested majority support for a republic, the Turnbull/Keating proposed model (appointed president) was defeated. Analysis assumes alternative of elected president would also be defeated. So, suggestion is "vote on principle of referendum first, then choose model". Sounds convincing, BUT
On the stated facts, status quo would beat either alternative and is therefore the Condorcet winner. On most theories of voting it should be selected.

An open thread on the insurrection in Brazil. I'd particularly be interested in comments from a Latin American perspective.
Dasein and Der Fuhrer
Back in the Paleolithic days of blogging, I got interested in the relationship between philosophical thought and political action, particularly in the cases of Hayek and Heidegger and their support for Pinochet and Hitler respectively. I think the evidence is in on Hayek (see here and here), so I won't discuss it further.
In Heidegger's case, there's been plenty more evidence on Heidegger's personal conduct, cumulatively quite damning. But the claim that he was one of the greatest of 20th philosophers remains widely accepted. This seems to imply (via an easy application of modus ponens), that his support for Hitler was not a consequence of his central philosophical ideas. The typical version of this claim attributes Heidegger's embrace of Nazism to some combination of opportunism
Why the (US) right is always wrong … and how both-sidesists help to ensure this
A decade ago, when the issue of Republican anti-science bias was raised, a common response was to point to attitudes to vaccination, where, it was claimed, Democrats were the anti-science party. I observed at the time that this claim wasn't justified by the available evidence. A little later, I noted the likelihood of the Republicans becoming anti-vax , a point on have been proved tragically right by the Covid pandemic.
But this case, and many more like it, hasn't prevented the publication of a continued stream of pieces starting from the premise that "both sides do it". The latest iteration relates to housing policy, and the claim that Democrats are the party of NIMBYism. For example this piece in The Atlantic by Jerusalem Demsas states

That's the headline for my latest piece in Inside Story, a review of Brad DeLong's Slouching Towards Utopia and Sebastian Edwards The Chile Project . Some extracts
The Chile Project, of which Edwards was a generally sympathetic observer, ranks with Thatcher's Britain as the paradigmatic case of what I've called "hard neoliberalism," which combines authoritarianism and radical free-market policies …Outside the United States, soft neoliberalism was often described as the Third Way. Its central theme was the idea that the goals of social democracy (or liberalism in the US sense) could best be achieved by embracing market-oriented reforms, and particularly financial deregulation, while maintaining a generally redistributive welfare state.

The Washington Post has a long piece about a Virginia family whose current (substantial but not huge) wealth derives from their slaveholding forebears and who may now be greatly enriched by the discovery of uranium under their land. There's an interesting discussion of the arguments for and against reparations
Buried in the middle of the article is something much more interesting, to me at any rate. One member of the family, Edward Coles, opposed slavery. He hid his views until he inherited ownership of 17 enslaved people, then took them to Illinois and freed them. None other than Thomas Jefferson wrote to Coles, seeking to dissuade him.
Jefferson wrote Edward a letter on Aug. 25, 1814, trying to talk him out of it.

My latest piece from Independent Australia, on my Substack
Another nuclear renaissance?
And did environmentalists kill the last one?
There has been a lot of talk lately about a revival of nuclear power, partly in response to the need to replace the energy previously supplied by Russia, and partly as a longer-term response to climate change. To the extent that this means avoiding premature closure of operational nuclear plants, while coal is still operating, this makes sense. But new nuclear power does not.
The misconception that nuclear makes economic sense remains widespread, but has been refuted many times. Less remarked on is the misconception is that the big obstacle to nuclear power is opposition from environmentalists.
Environmentalist opposition was a big factor in the decline of nuclear power in the late 20th century, but not since then in most
No new coal
Thanks to the efforts of Environmental Justice Australia (EJA) and the Environment Council of Central Queensland (EcoCeQ,), Environment Minister Tanya Plibersek reopened the environmental assessment process for 16 coal mines and two gas projects that had previously been approved. To take part, it was necessary to submit new information not available at the time of the original approvals.
I wrote the same comment for all of the coal projects*.
I wish to draw attention to the following information which was not available at the time this project was approved. This information implies that the climate damage caused by the project will be worse than seemed likely at the time, while any offsetting benefits will be smaller.

Can Labor provide cost-of-living relief without feeding inflation and interest rates?
I was part of a panel who responded to this question for The Guardian
Here's my response
The economic situation facing the majority of Australian households is dire. However, the common framing of the problem in terms of the "cost of living" distracts attention from the real problem, which is the decline in the real purchasing power of wages. Having remained stagnant for years, wages have now fallen far behind inflation. Moreover, the average rate of tax paid is rising because of bracket creep and because of the expiry of the Morrison government's low- and middle-income tax offset, which was not extended in the October budget.
Under our current policy approach, economic welfare is declining

Vote for democracy (please!)
It seems highly likely that the Republican Party will win control of the US House of Representatives, and possibly also the Senate, next week. Unless the margin is so narrow that a handful of believers in democracy can tip the balance, that will mean the end of electoral democracy in the US for the foreseeable future. Most House Republicans voted to overturn the 2020 election. All (except a few who were on the way out) voted against the Electoral Count Act which is supposed to make cheating more difficult, but which will surely be ignored if necessary. That's without considering the vast numbers of election deniers who will win (or already hold) crucial offices at state and local level, and the likelihood that the Supreme Court will enable them further.

Labor's love lost:the tide is turning on private ownership of electricity grids
I'm not a fan of the convention that newspaper and magazine editors choose the headline for articles, but I liked this one in The Conversation. The heading is neat and the sub-heading gives you the tl;dr version.
The promise by the Andrews government to reintroduce public enterprise to Victoria's electricity industry, through a revived State Electricity Commission, is something of a shock.
The process of electricity privatisation in Australia began with Labor in Victoria, when the government of Joan Kirner sold 51% of the Loy Yang B power station in 1992. Her Liberal successor, Jeff Kennett, then sold the remainder of Loy Lang B, as well as the rest of the state's publicly owned generation, transmission and distribution assets.

On Thursday there will be elections in the Manchester area including ward by-elections, Manchester Central constituency and the Police Commissioner elections.
Tens of thousands of UNISON members including hundreds from this Branch took part in the TUC 'March for an Alternative' only a few weeks ago.
Because of past disappointments some members view all parties as being the same.
But experience of this Government and its loathing of public services and contempt for working people proves there are very real differences.
The Government is hoping a low turnout will benefit right wing candidates, particularly in the Commissioner elections.
Every member is urged to use their vote in these elections on Thursday and to encourage family colleagues and friends to do the same.
This Coalition Government is looking to continue its ruinous 'austerity ' policies which are destroying our economy, services and our communities.
Take the time this Thursday to Vote for an Alternative.

Q: How to add data to two tables linked via a foreign key? If I were to have 2 tables, call them TableA and TableB. TableB contains a foreign key which refers to TableA. I now need to add data to both TableA and TableB for a given scenario. To do this I first have to insert data in TableA then find and retrieve TableA's last inserted primary key and use it as the foreign key value in TableB. I then insert values in TableB. This seems lika a bit to much of work just to insert 1 set of data. How else can I achieve this? If possible please provide me with SQL statements for SQL Server 2005.

A: That sounds about right. Note that you can use SCOPE_IDENTITY() on a per-row basis, or you can do set-based operations if you use the INSERT/OUTPUT syntax, and then join the the set of output from the first insert - for example, here we only have 1 INSERT (each) into the "real" tables:
/*DROP TABLE STAGE_A
DROP TABLE STAGE_B
DROP TABLE B
DROP TABLE A*/
SET NOCOUNT ON

CREATE TABLE STAGE_A (
    CustomerKey varchar(10),
    Name varchar(100))
CREATE TABLE STAGE_B (
    CustomerKey varchar(10),
    OrderNumber varchar(100))

CREATE TABLE A (
    Id int NOT NULL IDENTITY(51,1) PRIMARY KEY,
    CustomerKey varchar(10),
    Name varchar(100))
CREATE TABLE B (
    Id int NOT NULL IDENTITY(1123,1) PRIMARY KEY,
    CustomerId int,
    OrderNumber varchar(100))

ALTER TABLE B ADD FOREIGN KEY (CustomerId) REFERENCES A(Id);

INSERT STAGE_A VALUES ('foo', 'Foo Corp')
INSERT STAGE_A VALUES ('bar', 'Bar Industries')
INSERT STAGE_B VALUES ('foo', '12345')
INSERT STAGE_B VALUES ('foo', '23456')
INSERT STAGE_B VALUES ('bar', '34567')

DECLARE @CustMap TABLE (CustomerKey varchar(10), Id int NOT NULL)

INSERT A (CustomerKey, Name)
OUTPUT INSERTED.CustomerKey,INSERTED.Id INTO @CustMap
SELECT CustomerKey, Name
FROM STAGE_A

INSERT B (CustomerId, OrderNumber)
SELECT map.Id, b.OrderNumber
FROM STAGE_B b
INNER JOIN @CustMap map ON map.CustomerKey = b.CustomerKey

SELECT * FROM A
SELECT * FROM B

A: If you work directly with SQL you have the right solution.
In case you're performing the insert from code, you may have higher level structures that help you achieve this (LINQ, Django Models, etc).

A: If you are going to do this in direct SQL, I suggest creating a stored procedure that takes all of the data as parameters, then performs the insert/select identity/insert steps inside a transaction.  Even though the process is still the same as your manual inserts, using the stored procedure will allow you to more easily use it from your code.  As @Rax mentions, you may also be able to use an ORM to get similar functionality.

Study sheds light on the peculiar 'normal' phase of high-temperature superconductors
It reveals an abrupt transition in cuprates where particles give up their individuality; the results flip a popular theory on its head

Every character has a back story, and so do high-temperature superconductors, which conduct electricity with no loss at much higher temperatures than scientists once thought possible. To figure out how they work, researchers need to understand their "normal" state, which gives rise to superconductivity when the material is cooled below a critical transition temperature and the density of free-flowing electrons is tweaked in a process known as "doping."
Even in their normal state, these materials are pretty peculiar. Now, an experiment at the Department of Energy's SLAC National Accelerator Laboratory has probed the normal state more accurately than ever before, and discovered an abrupt shift in the behavior of electrons in which they suddenly give up their individuality and behave like an electron soup.
A research team from SLAC and Stanford University described the results in Science.
"The abnormality of this normal state is suspected to be the reason why these superconductors are such good superconductors," says Dirk Van Der Marel, a researcher at the University of Geneva who was not involved in the study.
"This study has essentially overthrown a very popular and hotly debated theory, called quantum critical point theory, that is thought to underlie superconductivity not only in this material, but in other materials as well. This is a disruptive finding, but it's a step forward, because it frees our minds to explore other ideas."
Exploring a well-known cuprate
The study was carried out on a compound called Bi2212, one of the most thoroughly studied high-temperature superconductors. As a copper oxide, or cuprate, it's part of a family of compounds where high-temperature superconductivity was first discovered more than 30 years ago.
Scientists across the world have been working ever since to understand how these materials function, with a goal of finding superconductors that operate at close to room temperature for applications like perfectly efficient power lines.
One of the most important tools for studying these materials is angle-resolved photoemission spectroscopy (ARPES). It uses light - in this case a beam of ultraviolet light from SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) - to kick electrons out of the material and measure their energy and momentum. This reveals how the electrons inside the material behave, which in turn determines its properties.
In superconductivity, for instance, electrons overcome their mutual repulsion and form a sort of collective soup in which they can pair up and flow past obstacles without losing any of their energy.
Frustrated electrons
Earlier generations of so-called conventional superconductors, which operate only at extremely low temperatures, are conventional metals in their normal state, where their electrons act independently, as they do in most materials.
But in cuprates the picture is very different. Even in their normal, non-superconducting state, electrons seem to recognize each other and act collectively, as if they were dragging each other around, in what's known as "strange metal" and even "incoherent strange metal" behavior.
"In a way you can think about these electrons as being frustrated," said Zhi-Xun Shen, a professor at Stanford and SLAC and investigator with the Stanford Institute for Materials and Energy Sciences (SIMES) at SLAC who led the study. "In other words, the electrons have sort of lost their individual identity and become part of the soup. This is a really interesting, challenging state to describe in theoretical ways."
It's been hard to explore these fascinating normal states at the warm temperatures where they occur, said Su-Di Chen, a Stanford graduate student who performed the experiments with SLAC postdoctoral researcher Yu He, Stanford postdoc Jun-Feng He and SSRL scientist Makoto Hashimoto. The theoretical part of the study at SLAC was led by SIMES Director Thomas Devereaux.
A surprisingly sharp boundary
In ARPES experiments, samples are usually placed in a cold environment inside a vacuum chamber to minimize contamination of the surface, Chen said: "But even if you put them in an ultra-high vacuum, residual gas molecules can still attach to the sample surface and affect the quality of our measurement. This problem gets worse when you warm the environment around the sample to the temperatures where the normal states exist."
To get around this, Hashimoto said, the team found a way to warm the sample, which is about the size of the tip of a ballpoint pen, by warming just the part of the setup that holds it while keeping everything else cold. This allowed them to examine the electrons' behavior across a range of temperatures and doping levels.
"What we saw was that as you increase the level of doping, there's a very sharp boundary," Hashimoto said. "On one side the electrons are jammed, or frustrated. Then, as more electrons are added, they suddenly start moving smoothly, an indication that the material is now a conventional metal. This transition was known to happen, but the fact that it was so sharp was a real surprise."
A challenge for theory
The results pose a challenge for theorists who still struggle to explain how high-temperature superconductors work, said paper co-author Jan Zaanen, a theoretical physicist at the University of Leiden in The Netherlands.
Current theory predicts that because changes in the nature of Bi2212 are gradual at very low, superconducting temperatures, they should also be gradual at the higher temperatures where the material is in a normal state, he said. Instead the high-temperature changes are abrupt, like what happens when a pot of water starts to boil: You can see either water or bubbles of steam in the roiling pot, but nothing in between.
"There are quite a number of reasons to believe that the strange metal in the normal state may be an example of densely entangled matter," Zaanen said. "Entanglement is the property of the quantum world that sharply distinguishes it from anything classical. We have no theoretical machines, be it classical computers or the available mathematics, that can describe it!
"But quantum computers are designed to handle such densely entangled stuff," he said. "My dream is that these results will eventually land on the top of the list of benchmark problems for the quantum computing community to solve."
SSRL is a DOE Office of Science user facility. Samples for the study were grown by Hiroshi Eisaki of the National Institute of Advanced Industrial Science and Technology in Japan. The work was funded by the DOE Office of Science.

Die Stahlschwalbe (Hirundo atrocaerulea) ist eine Vogelart aus der Familie der Schwalben (Hirundinidae).

Der Vogel kommt im Südosten der Demokratischen Republik Kongo, in Südtansania, Malawi, im Nordosten Sambias, in Ostsimbabwe und angrenzendem Mosambik, im Osten Südafrikas und in Eswatini vor und überwintert in Uganda, im Nordosten der Demokratischen Republik Kongo und im äußersten Westen Kenias.
Der Lebensraum umfasst offenes Grasland, Waldränder und Sumpfgebiete von 850 bis 2000 m Höhe.

Der Artzusatz kommt von  und .

Dieser Vogel ist ein Zugvogel. Nach der Brutzeit bilden sich Schwärme von 40 oder mehr Individuen. Der Vogel hält sich von Ende April bis Ende September im Bereich des Viktoriasees auf und kehrt oft in dasselbe Brutgebiet zurück, die Männchen vor den Weibchen.

Merkmale
Die Art ist 18–25 cm groß und wiegt etwa 13 g, eine charakteristische dunkelblaue Schwalbe. Das Gefieder hat einen stahl-blauen Glanz, mitunter mit etwas Violett. Manchmal finden sich einige weiße Strichelungen oder Flecken an den Flanken, auch am Nacken und Bürzel, die äußeren Schwanzfedern sind sehr lang und dünn. Beim Weibchen ist der Schwanz kürzer. Jungvögel sind blasser gefärbt mit brauner Kehle und Brust und weniger Glanz auf der Oberseite. Manchmal sind auch einzelne weiße Federn am Nacken, den Flanken und dem Bürzel zu sehen.

Die Art kann mit der Erzschwalbe (Psalidoprocne pristoptera) verwechselt werden, der einzigen ähnlichen ganz dunklen Schwalbe, hat aber einen wesentlich längeren Schwanz, außerdem ist das Gefieder glänzend dunkelblau und nicht schwarz. Zudem fliegt sie gleichmäßiger.

Die Art ist monotypisch.

Stimme
Der Gesang wird als monoton klagend, aber auch als melodisches "bee-bee-bee" beschrieben, die Rufe als "choop-choop", "chip chip" und schnelles "chip-pu-pu".

Lebensweise
Die Nahrung besteht hauptsächlich aus Insekten, die einzeln oder paarweise, manchmal auch in kleinen Gruppen gejagt werden, meist dicht über dem Erdboden in einem begrenzten Gebiet, manchmal aber auch in 50 bis 100 m Höhe.
Die Brutzeit liegt im Februar in der Demokratischen Republik Kongo, zwischen November und Dezember und im Februar in Tansania, zwischen Oktober und Januar in Malawi, zwischen November und Januar in Sambia, im Dezember in Mosambik, zwischen Oktober und März in Simbabwe und Südafrika. Zwei Bruten sind möglich. Die Nester stehen in aller Regel einzeln, Konkurrenten werden aggressiv vertrieben. Während der Balz fliegt das Männchen dicht über das Weibchen mit aufwärts gestreckten Flügeln, gespreiztem Schwanz und in den Nacken gelegtem Kopf. Beide bauen das Nest aus Lehm, mit Haaren, Gras, Wurzeln und Federn ausgelegt, an eine Wand oder ein Dach geklebt bis 5 m über dem Boden, auch in verlassenem Bau von Erdferkeln (Orycteropus afer), Flussufern, an Dolen oder Gebäuden. Die Nester können wiederverwendet werden.

Das Gelege besteht aus 2 bis 4, meist 3 Eiern, die vom Weibchen über 14 bis 17 Tage bebrütet werden. Beide Elternvögel füttern die Jungen.

Gefährdungssituation
Der Bestand gilt als "gefährdet" (Vulnerable) aufgrund Habitatverlustes.

(HealthDay News) — Results of a small study suggest that Parkinson's patients seem to improve if they think they're taking a costly medication. The findings have been published online Jan. 28 in Neurology.
In the study, 12 patients had their movement symptoms evaluated hourly, for about four hours after receiving each of the placebos. On average, patients had bigger short-term improvements in symptoms like tremor and muscle stiffness when they were told they were getting the costlier of two drugs. In reality, both "drugs" were nothing more than saline, given by injection. But the study patients were told that one drug was a new medication priced at $1,500 a dose, while the other cost just $100 — though, the researchers assured them, the medications were expected to have similar effects.
Yet, the researchers found that when patients' movement symptoms were evaluated in the hours after receiving the fake drugs, they showed greater improvements with the pricey placebo. What's more, magnetic resonance imaging scans showed differences in the patients' brain activity, depending on which placebo they'd received. The patients in the study didn't get as much relief from the two placebos as they did from their regular medication, levodopa. But the magnitude of the expensive placebo's benefit was about halfway between that of the cheap placebo and levodopa. What's more, patients' brain activity on the pricey placebo was similar to what was seen with levodopa.

In the statement Russian Defense Ministry announced that "for the first time in history, the crew of a Bastion coastal defense system of the Pacific Fleet launched an Oniks cruise missile from the territory of the Chukotka Autonomous Region."
According to the ministry's data, the missile struck a target vessel at a distance of over 200 km in the Sea.
The Oniks missile was fired in accordance with the combat training plan. About 10 warships and support vessels of the Pacific Fleet and naval aviation provided for the safe missile launch.
The P-800 Oniks supersonic missile has a maximum range of about 500 km. Therefore, Bastion coastal defense systems deployed on the Chukotka Peninsula are capable of striking targets along the entire eastern part of the Northern Sea Route, from the De Long to the Bering Straits.
